Dear Mr. Pinkerton:

                   Nuveen Commodities Income and Growth Fund
             Nuveen Commodities Income and Growth Master Fund LLC
                                  333-130360
                                 333-130360-01

   This letter responds to the comments contained in your letter dated
January 13, 2006, regarding the initial registration statement on Form S-1 of
Nuveen Commodities Income and Growth Fund (the "Fund") and Nuveen Commodities
Income and Growth Master Fund LLC, as co-registrant (the "Master Fund"). For
convenience, each of your comments is repeated below, with responses
immediately following.

   The response to each of these comments is included in pre-effective
amendment no. 1 which was filed with the SEC on the date of this letter. A copy
of that amendment, marked to show changes from the registration statement as
originally filed, is enclosed for your convenience.

1. Comment: We note that you have omitted a great deal of information that is
either currently available to the pool or that materially affects the ability
of the pool to conduct the proposed offering. For example, we note that you
have included no disclosure regarding the specific fees the pool will pay,
break-even disclosure or capsule performance data for Gresham. Please provide
this information in your next amendment. Further, include the financial
statements required by Form S-1.

   Response: Agreed. The financial statements will be included in a subsequent
filing as soon as they are available.

2. Comment: Please tell us supplementally why you believe your proposed
operations will not subject you to regulation as an investment company under
the Investment Company Act of 1940.


   Response: The Fund invests all of its assets in a Master Fund (for purposes
of this comment, the Fund and Master Fund are collectively referred to as "the
Fund"). The Fund is not subject to regulation as an investment company under
the Investment Company Act of 1940 because the Fund is primarily engaged in a
business other than that of investing, reinvesting, owning, holding or trading
in securities, and, as a result, is not an investment company under
Section 3(b)(1) of the 1940 Act. We believe that the Fund is primarily engaged
in the business of a commodity pool, and that this conclusion is supported by
an analysis of the Fund's structure and operations under established standards
enunciated by the staff of the Division of Investment Management in the Managed
Futures Association no-action letter (pub. avail. July 15, 1996) ("MFA") and
the Peavey Commodity Futures Fund no-action letter (pub. avail. June 2,
1983)("Peavey").

   In Peavey, the SEC staff stated that they would not consider an entity to be
subject to SEC jurisdiction under the Investment Company Act if it was directly
or indirectly primarily engaged in the business of investing in futures (even
if those futures were considered to be securities and subject to SEC
jurisdiction). In discussing its reasoning, the SEC staff recognized that the
traditional analysis for assessing an entity's status for Section 3(b)(1)
purposes may not reveal the primary nature of a commodity pool's business.
Instead the SEC staff articulated an alternative test for commodity pools,
stating that in making the Section 3(b)(1) determination, "...[the staff] would
consider of first importance the area of business in which the entity
anticipates the realization of the greatest gains and exposure to the largest
risks of loss." In Peavey, the SEC staff also clearly recognized that in
determining a commodity pool's "primary business" for purposes of assessing its
status under the 1940 Act, a pool's cash reserves and margin deposits, often in
the form of government securities, do not indicate the primary nature of the
pool's business. Indeed, the Peavey letter stressed that a pool with even more
than 50% of its assets in securities would not necessarily indicate that the
pool is primarily engaged in investing in securities so as to constitute an
investment company.


   In MFA, the SEC staff considered the status under Section 3(b)(1) of a
commodity pool that invests all of its assets in other commodity pools. After
citing the Peavey test, the SEC staff further refined its analysis of the
applicable Section 3(b)(1) determination, stating as follows:

   In our view, therefore, a commodity pool's primary business should be deemed
   to be investing or trading in commodity interests if, (1) the pool looks
   primarily to commodity interests as its principal intended source of gains,
   (2) the pool anticipates that commodity interests present the primary risk
   of loss, and (3) the pool's historical development, public representations
   of policy (in its prospectus or offering circular and in marketing
   materials), and the activities of those charged with management of the pool
   demonstrate that the pool's primary business is investing or trading in
   commodity interests, rather than securities.



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006

   Evaluating the Fund under the standards established by MFA and Peavey
reveals that the Fund is primarily engaged in a business other than investing
in securities and, thus, is not an investment company under Section 3(b)(1) of
the 1940 Act. As structured, the Fund primarily will purchase futures and
forward positions in a group of tangible commodities that will have an
aggregate notional value approximately equal to the total net assets of the
Fund. Additionally, the Fund will moderate the risks associated with its
commodity investments and generate positive net cash flow through writing calls
and buying puts on commodity interests. Because of the nature of commodity
trading, only a small portion of the value of a futures or forward contract is
necessary to be maintained with the broker or counterparty as a good faith
deposit toward performance of the contract. Consequently, as with all commodity
pools pursuing these types of strategies, the Fund will maintain large cash
reserves that are necessary to secure or margin its futures and forward
transactions. Moreover, these cash reserves, which are expected to normally
constitute, on average, in excess of 80% of the Fund's assets, will be invested
in short-term, investment grade, debt instruments, as these monies are subject
to the demand for margin by commodity brokers in the event of price changes in
the Fund's long futures and forward positions. Accordingly, the Fund's
investments of its cash reserves in debt instruments is strictly incidental and
corollary to its transactions in commodity interests.

   With respect to the realization of gains, the Fund's manager anticipates
that the Fund's long commodity positions will account for nearly all of the
Fund's short-term and long-term gains and its commodity call option writing
will thereby largely determine its total return. As for the potential for loss,
the Fund's greatest exposure results from the Fund's long futures and forwards
positions on commodity interests. Although the Fund's strategy seeks to
mitigate this risk through the purchase of out-of-the-money puts on commodity
interests (which protects against a significant decline in value of these
positions), the Fund's long commodity positions are expected to constitute
nearly 100% of the Fund's aggregate loss exposure.

   The Fund, of course, will have some potential to realize gains and losses
based on debt instruments purchased with those cash reserves that are not used
to purchase put options on groups of commodities or commodity indices. However,
the Fund's risk exposure from fluctuations in the value of these debt
instruments is minimal relative to the Fund's total risk exposure, due to the
high credit quality and short-term maturities of these securities. For these
same reasons, the potential for gains from these securities also is limited,
particularly relative to the potential gain from the Fund's commodity interest
positions.


   With regard to the remaining MFA factors, we note that the Fund's prospectus
(1) clearly states that the Fund is a commodity pool and that the manager is a
registered commodity pool operator subject to regulation by the CFTC and NFA
and (2) includes detailed risk factors clearly disclosing that the primary risk
of loss associated with this Fund relates to the proposed investments in the
commodity markets. Finally, the Fund will be marketed as a commodity pool and
not as an investment company.



Mr. Owen Pinkerton
Securities and Exchange Commission

   Based on the Fund's structure, its potential for the realization of the
greatest gains from the commodity investments and its exposure from those
investments to the largest risk of loss, and its public representations, we
believe that under the MFA and Peavey standards, the Fund is a classic example
of a commodity pool that may have a significant portion of its assets invested
in securities, but, under Section 3(b)(1) of the 1940 Act, nonetheless is
primarily engaged in a business other than that of an investment company.

3. Comment: Please revise throughout the prospectus to provide disclosure
substantially similar to the disclosures that would be required by Industry
Guide 5 if real estate limited partnership units were being registered. For
example, your revisions should include a narrative discussion under an
appropriate major heading of the manager's and subadvisor's experience over the
past ten years similar to that required by Item 8A of Guide 5, which includes,
among other things, a description of any major adverse business developments
and conditions that were experienced by prior programs. In addition, please
revise the cover page to briefly discuss the most material risks to
shareholders of an investment in your securities.

   Response: Agreed. In addition, the cover page has been revised to include
risk disclosure language.

4. Comment: Please confirm that your shares have been approved to trade on a
stock exchange. If not, revise your disclosure to indicate, if true, that you
have applied to have your shares quoted or listed for trading rather than "will
be" listed for trading. Further, revise to identify the exchange in which you
intend to trade your shares.

   Response: The Fund has begun the process to apply to have its shares listed
for trading on the American Stock Exchange. The prospectus has been revised
accordingly to indicate that application for listing has been made.

5. Comment: Please disclose why you decided to employ the master-feeder
structure for the pool rather than structure it as a traditional commodity pool
that does not employ a master fund and discuss the benefits or detriments of
this structure to investors.

   Response: The Registrants determined to employ the master-feeder structure
for the pool because it permits the Fund, as a grantor trust, to issue to its
owners an information statement for federal tax purposes that is based on a
Form 1099, rather than an information statement characterized as a "Schedule
K-1," although the information statement will be supplemented by further
information reflecting the Master Fund's tax status as a partnership. It is
anticipated that potential investors in the Fund would be more receptive to the
Form 1099-type of tax reporting than to a conventional Schedule K-1 that would
be issued directly by the Master Fund in the absence of a master-feeder
structure. A discussion of the tax reporting is included in the summary on page
9 under "U.S. Federal Income Tax Aspects" and in the body of the document on
page 58 under "Federal Income Tax Consequences - Certain U.S. Federal Income
Tax Consequences to U.S. Taxpayers." There are additional costs associated with
using this particular master-feeder structure (such as the expenses associated
with having a trustee - in this case, Wilmington Trust



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 5

Company), but the Registrants do not believe those costs are material or will
negatively affect shareholders. The following sentence has been added to page
23 of the prospectus under "The Master Fund's Investments."

   The Fund determined to employ a two-tierd, "master-feeder" structure in
   order to permit the Fund, as a grantor trust, to issue an IRS Form 1099
   supplemented by additional tax information relating to the Master Fund's tax
   status as a partnership. See "Federal Income Tax Considerations." There are
   additional costs associated with using a master-feeder structure (such as
   the expenses associated with having a Delaware Trustee) but the Fund does
   not believe these costs are material or will negatively affect shareholders.

6. Comment: Please revise to indicate the factors considered in determining the
offering price. Refer to Item 505 of Regulation S-K.


   Response: Because the Fund has no history of operations (and there has been
no public market for the shares), the offering price was not based on an
intrinsic value or on other fundamental factors. The offering price was set by
the Fund in a manner substantially similar to other public offerings of
commodity pools. Because there are no material factors underlying how the
offering price was determined, it is proposed that no additional disclosure be
added to the prospectus.


7. Comment: Please provide us with a complete copy of any sales material which
includes all illustrations and other inserts in the form you expect to
distribute to investors in accordance with Release No. 33-6900 and by analogy
to Item 19D of Guide 5. We may have further comment after we receive your
materials.

   Response: Agreed. These materials (which will present a balanced discussion
of both the risks and rewards of investment in the Fund consistent with the
prospectus) will be forwarded to you as soon as they are available.

8. Comment: Your prospectus contains many defined terms, legalese and dense,
embedded lists that make it more difficult to read. Reduce your over-reliance
on defined terms, legalese and embedded lists of dense information. As you
revise your document, consider minor changes that would make the material
information clear, concise, and more understandable. For example, a shortened
version of a full name is often clear from context, as are commonly known
acronyms. In addition, please refrain from capitalizing terms that are clear
from their plain meaning, including, without limitation, "Shares."

   Response: Agreed. Appropriate changes have been made throughout the document.

9.  Comment: Please restrict the disclosure found on the cover page to that
which is required by Item 501 of Regulation S-K, Release No. 33-6900 and
information that is key to an investment decision.

    Response: Agreed. The cover page has been revised accordingly.

10. Comment: Please ensure that your cover page does not exceed one page. See
501(b) of Regulation S-K.

    Response: Agreed. The cover page has been revised accordingly.

11. Comment: Please disclose on the cover page that investors must purchase a
minimum of 100 shares in this offering. In addition, please identify your
subadvisors on the cover page and their affiliations, if applicable, to the
pool.

    Response: Agreed. The cover page has been revised accordingly.

Special Note Regarding Forward-Looking Statements, page iii

12. Comment: Please remove your statement that "neither the Manager nor any
other person assumes responsibility for the accuracy or completeness of the
forward-looking statements." In addition, please relocate this section as well
as the section entitled, "Patent Application Pending" so that they appear in
the body of the prospectus.


    Response: Agreed. The above-noted statement has been deleted. The sections
noted above have been moved to page 14 of the prospectus after "Fees and
Expenses."


Prospectus Summary

13. Comment: Please limit your summary to a concise description of the material
characteristics of the pool and the material terms of your offering.

    Response: Agreed. The summary has been revised accordingly.

The Fund, page 1

14. Comment: Please disclose the dates the pool and the Master Fund were
organized. It is not clear why this information is not available.

    Response: Agreed. The Master Fund and the Fund were both organized on
December 7, 2005. This information has been added on page 1 of the prospectus.



Mr. Owen Pinkerton
Securities and Exchange Commission

Page 7

Investment Objectives, page 2

15. Comment: Please revise to separately quantify the portion of your proceeds
that will be used to purchase (1) commodities pursuant to Gresham's Tangible
Asset Program; (2) options pursuant to your "Option Strategy"; and (3) debt
instruments.


    Response: Agreed. The requested information has been added on pages 25 and
26 of the prospectus.


Break-even Threshold, page 9

16. Comment: We note your statement that the Break-even point is based on the
"Master Fund's initial minimum size." Please advise us as to the meaning of
this statement. The offering itself is a firm commitment underwritten offering,
not a minimum/maximum continuous offering. Please advise. This comment also
applies to your disclosure on page 10 of the "Maximum Amount Offered" in this
offering.

    Response: The above-noted statement has been deleted. The break-even
analysis has been revised to reflect that the table is based on an estimate of
$250 million offering size. Since the offering is a firm commitment
underwriting, the actual size of the Fund will not be known until the initial
offering has closed.

Break-even Analysis, page 11

17. Comment: Please clarify why you have included two separate columns for your
break-even table in light of the fact that the offering is a firm commitment
underwritten offering. In addition, please revise the table to include the
selling commissions or underwriting commissions that will be paid to the
underwriters in connection with this offering or tell us why you do not believe
this information is required.

    Response: The table has been significantly revised in response to the
staff's comment and to incorporate additional information.

18. Comment: By footnote, please disclose what fees are included under
"Offering and Organizational Expenses" and "Operating Expenses"

    Response: Agreed. The necessary footnote information has been included in
the table.

Risk Factors, page 15

19. Comment: Some of your risk factors fail to specifically state the risk that
may flow from the facts and circumstances you describe. For example, but not
limited to, under Fund performance may be hindered by increased competition for
positions on page 15 you fail to state the risk that will result from increased
competition. Also, see Gresham historic performance



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 8

record on page 15. Please review and revise your risk factors to include a
discussion of how these risks affect Nuveen or the securities being offered.

    Response: Agreed. The risks identified in this comment and other risks have
been revised to more specifically state the risk described.

20. Comment: Please review your risk factor subheadings to ensure they reflect
the risk you describe in the text. Some of your subheadings merely state facts
about your business. For example, The Master Fund will rely heavily on key
personnel at Gresham to manage the master Fund's commodity interest on page 18.
Also, see, but not limited to:

    .  Shareholders have limited voting rights..., page 18;
    .  The Master Fund pays fees and expenses regardless of profitability, page
       19; and
    .  You will not be able to review the Fund's holdings on a daily basis,
       page 19.

Please review and revise subheadings to succinctly state the risks that will
result from the facts or circumstances you discuss.

    Response: Agreed. Several of the "Risk Factors" subheadings, including but
not limited to those identified in this comment, have been revised in response
to this comment.

21. Comment: Please discuss only risks that are material to you. Your risk
factors section should not describe any possible risk to the company, no matter
how remote. For example, under Regulatory changes could restrict the master
Fund's Operation's, page 20, you discuss the risk of a disruption on
operations. Please describe, in a manner specific to the company and its
planned operations, how you would be at risk different from other similar
companies. Please review all of your risk factors and if necessary, revise or
delete them with this comment in mind.

    Response: Agreed. Certain risk factors have been deleted, and others
revised, in response to this comment.

22. Comment: Please revise to include a risk that discusses the possibility of
conflicts of interest. In this regard, we note your disclosure on page 30.


    Response: Agreed. A risk factor discussing conflicts of interest has been
added on page 20.


Commodity Investment Strategy Risks, page 15


Investments in commodity interests are volatile and may result in losses, page
15


23. Comment: Please discuss what makes the investment volatile, including the
use of leverage and the general nature of the futures markets. As part of this,
please discuss the fact that



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 9

trading in the commodities markets is a "zero-sum game" which is not the case
with trading equity securities.


    Response: For the staff's information, the Fund does not presently intend
to use leverage in the sense that the Fund's long commodity positions will not
exceed the value of its net assets. The Fund does not intend to carry "short"
positions (i.e., the call options that the Fund writes will be covered) whereby
the portfolio exposure could exceed the Fund's net assets. The Fund does not
believe that the "zero-sum game" disclosure is meaningful to investors because
the potential for loss has been disclosed and the significant fact to emphasize
to investors is the volatility itself. Moreover, based on historical returns
from long-only, broad-based commodity investments (in contrast to "commodity
trading"), the Fund believes that it might be misleading to characterize a
long-only commodity investment program as a "zero-sum game."


Swap contracts and other contracts traded on a principal basis are subject to
counterparty credit risks, page 15

24. Comment: In order to give depth to your disclosure, please revise to
quantify the percentage of assets that you intend to invest in swap contracts
and other instruments that are not cleared by an exchange or clearinghouse.


    Response: The Master Fund does not intend to invest in swap contracts and
the disclosure has been revised on page 20 and throughout the document
accordingly. As a result, the risk discussed above has been deleted. In
addition, the Master Fund will not invest more than 5% of its assets in other
instruments that are not cleared by an exchange or clearinghouse (virtually all
of which will be OTC put options on a group of commodities or commodity indices
(such as the DJ/AIG or the GSCI) in order to closely resemble the price
movements of the TAP/SM/ positions). The following language has been added on
page 20 and throughout the document as necessary:


    The Master Fund does not expect that more than 5% of the Master Fund's net
    assets will be used to purchase OTC commodity put options, although the
    value of the commodities underlying these OTC commodity put options may
    represent up to 100% of the notional value of the Master Fund's commodity
    investments.

Risk that the Fund's Shares will trade at a Discount to Net Asset Value, page 17

There is a risk that the Fund's Shares may trade at prices other than the
Fund's net asset value per unit, page 17

25. Comment: Please expand this risk factor to describe in more detail why you
believe the trading prices of your shares will fluctuate in accordance with NAV
and the risk to investors if your NAV does not correlate to the market price.



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 10

    Response: Agreed. The following language replaces the current disclosure:

    The net asset value of each share will change as fluctuations occur in the
    market value of the Master Fund's portfolio. Investors should be aware that
    the public trading price of a share may be different from the net asset
    value of a share. The price difference may be due, in large part, to the
    fact that supply and demand forces at work in the secondary trading market
    for shares is closely related to, but not identical to, the same forces
    influencing the prices of the commodity contracts and other instruments
    held by the Master Fund at any point in time.

Commodity Subadvisor Risks page 17

Speculative position and trading limits may reduce profitability page 18

26. Comment: Mitigating language is not appropriate in the discussion of a risk
factor. Please remove the third sentence under this subheading

    Response: Agreed. Mitigating language has been deleted as noted in your
comment and elsewhere as appropriate.

Fund performance may be hindered by increased competition for positions, page 18

27. Comment: Please expand this risk factor to note that increased competition
also tends to lead to more severe price swings since more market participants
hold larger positions than in the past which makes it difficult to liquidate
such positions.

    Response: Agreed. The existing risk factor has been deleted and the
following language has been added on page 18:

    Increased competition could reduce the profitability of the commodity
    subadvisor. The commodity subadvisor believes that there has been, over
    time, an increase in interest in commodity investing. As the capital under
    management on the same general principles increases, an increasing number
    of traders may attempt to initiate or liquidate substantial positions at or
    about the same time as the commodity subadvisor, or otherwise alter
    historical trading patterns or affect the execution of trades, to the
    detriment of the Fund.



Mr. Owen Pinkerton
Securities and Exchange Commission

An investment in the Fund may not necessarily diversify an investor's overall
portfolio, page 19

28. Comment: Please clarify whether the investment performance of commodity
interests has generally been non-correlated or negatively correlated to equity
and debt securities. Non-correlated and negative correlation have significantly
different meanings. Please provide us with support for your contention that
commodity interests have historically been negatively correlated to equity and
debt securities.

    Response: Agreed. In addition, supporting documentation relating to a low
negative correlation between the investment performance of commodity
investments and other asset classes such as equity securities and debt
securities is attached as Exhibit A to this letter.

Risk of Investing in Non-U.S. Markets, page 19

Investing in Non-U.S. markets would expose the Master Fund to additional credit
and regulatory risk, page 19

29. Comment: In order to give depth to this risk, please quantify the portion
of your assets that you intend to invest through foreign markets and exchanges.

    Response: Agreed. The following disclosure has been added on page 19:


    The Master Fund currently expects that up to 30% of its investments in
    commodity futures and forward contracts, options on commodity futures and
    forward contracts and OTC commodity put options may be invested in non-U.S.
    markets.


Operating Risks, page 20

Shareholders' liability may not be limited in certain circumstances...page 20

30. Comment: Please delete the words "although unlikely" in the second sentence
under this heading as mitigating language is not appropriate in the risk factor
section. Provide similar revisions to the third sentence in the second
paragraph beginning with "although."


    Response: Agreed. The requested changes have been made, and the above-noted
disclosure has been moved to page 51 under "Declaration of Trust and LLC
Agreement."




Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 12

The Master Fund pays fees and expenses regardless of profitability, page 21

31. Comment: Please quantify the fees that the Master Fund must pay.

    Response: Agreed. The risk noted above has been revised and the following
language has been added:


    Those fees and expenses include asset-based management fees of up to
    1.25% per year and brokerage fees and operating expenses expected to be
    approximately 0.59% per year. Assuming underwriting discounts and
    commissions of 4.5%, the Master Fund will have to generate profits,
    exclusive of interest income, of 2.44% per year during its first year of
    operations in order for an investor in this offering to break even for the
    year. Consequently, the expenses of the Master Fund could, over time,
    result in significant losses to your investment therein. You may not
    achieve profits, significant or otherwise.


The Master Fund's Investments, page 23

32. Comment: Please disclose any provisions in the Declaration of Trust and LLC
Agreement or otherwise that would limit the fund's ability to invest in
products other than the ones you have identified, use leverage, or borrowings
in its investment strategy. Disclose whether there are any limits on the
Manager's ability to change the fund's investment strategy.


    Response: Agreed. The following disclosure has been added as the first
paragraph on page 23 under "The Master Fund's Investments."


    There are no provisions in the Fund's Declaration of Trust or the Master
    Fund's LLC Agreement or otherwise that limit the ability of the Master Fund
    to change its investment strategy (including the types of products in which
    the Master Fund may invest). The Fund has no present intent to use leverage
    or borrowings.

33. Comment: Please clarify whether investment policies disclosed on pages
22-24 refer to the policies that Gresham, as your CTA, will follow in
connection with its TAP Program, or whether they refer to additional
investments in commodity interests that the pool may make in addition to its
investment in the TAP Program. Your disclosure appears to indicate that these
investments will be made directly by the Master Fund which would imply that
they are separate from the investment in the TAP Program. If so, please
indicate the portion of your portfolio that will be comprised of these
discretionary trades.

    Response: Agreed. The disclosure has been revised to clarify that the
Master Fund will not make investments outside of TAP/SM/ and the integrated
investment strategy.

34. Comment: We note that John P. Amboian is the President of the Manager and
Director and Principal Executive Officer of the Trustee. Please revise to
indicate the amount of time Mr. Amboian will serve in each capacity. In
addition, in light of the fact that he serves as an executive of the Manager
and Trustee, how the Trustee is considered to be unaffiliated with the Manager.

    Response: Wilmington Trust Company, a Delaware trust company, will serve as
the Delaware trustee of Fund. Mr. Amboian will not serve in that capacity and
the document has been revised accordingly.

35. Comment: For each of the named executives listed in this section of the
prospectus, please include all information required by Item 401 of Regulation
S-K. For example, please revise to include:

    .  Business experience for Mr. Zimmerman during the last 5 years;

       Mr. Spencer's biographical information;
    .  Whether Mr. Hepworth remains an executive of Falconwood and, if so, his
       position with Falconwood;

prospectus.

Gresham Investment Philosophy and Process, page 29

36. Comment: Please disclose the number of trading programs administered by
Gresham Investment. If none, state so.


    Response: Agreed. Gresham administers two trading programs: (i) TAP/SM/;
and (ii) TAP/SM/ and the integrated investment strategy. The prospectus has
been revised accordingly.


37. Comment: Please revise to further describe Gresham's TAP Program.
Specifically, include information regarding what the description "rules-based"
is meant to represent, whether the trading program is technical or fundamental
in nature and whether the program requires the existence of price trends in
order to be successful. In addition, where you discuss the concept of
"backwardation," please discuss how your program is able to determine that
backwardation is occurring and how frequently this occurs.

    Response: Agreed. The requested information has been included in the
prospectus.

38. Comment: Please disclose the duration of your agreement with Gresham and
any material terms in the agreement regarding the ability of Gresham or you to
terminate the agreement. In

addition, please disclose what criteria the Manager will use if it selects
additional CTAs or replaces Gresham.

    Response: Agreed. The following language has been added on page 32 as the
final paragraph before the subheading "Regulatory and Litigation":


    Unless earlier terminated, the manager's agreement with each of the
    subadvisors will remain in effect for two years from the commencement of
    the Master Fund's investment operations, and are renewable for periods of
    up to two years. The agreements may be terminated at any time, without
    penalty, by either the manager or a subadvisor upon 60 days written notice.
    If the manager determines in the best interests of shareholders to select
    additional CTAs or to replace a subadvisor, the manager will consider
    certain information with respect to each new CTA, including the following:


    .  general information including the identity of its affiliates and key
       personnel;

    .  investment strategy and risk management principles of the CTA;

    .  the CTA's financial condition;

    .  relevant performance history and the quality of services provided;

    .  fees and expenses; and

    .  capacity to take on new business.

39. Comment: In light of the fact that you anticipate that your securities will
be traded on a national securities exchange, please disclose whether and to
what extent there will be any transparency regarding your holdings at any given
time. If there will be no real-time transparency, please disclose this.

    Response: As noted in "Reports to Shareholders", the manager will furnish
Fund shareholders with annual reports as required by the rules and regulations
of the SEC as well as those reports required by the CFTC and NFA. In addition,
each month the manager will post on its website such information relating to
the Fund's shares as required by the CFTC and, on a voluntary basis, each
quarter (and perhaps more frequently) will disclose underlying Master Fund
holdings. The following sentence under "Reports to Shareholders" on page 14 has
been revised as follows (new text is underlined):

    In addition, each month the manager will post on its website
    (http://www.nuveen.com) (which is also the Fund's website) such information
    relating to the Fund's shares as the CFTC and the NFA may require to be
    given to participants in commodity pools (like the Fund) and quarterly (and
    perhaps more frequently) will post underlying Master Fund holdings.

Option Strategy, page 27

40. Comment: We note your strategy is based on "normal market circumstances."
Please revise to indicate what constitutes "normal market circumstances" and
examples of abnormal market circumstances and how you would respond to these
circumstances.

    Response: On page 27 and throughout the document, we have removed
references to "normal market circumstances." In addition, the following
language was added on page 27 as the final sentence of the first paragraph
under the subheading "The Manager":

    If the manager determines that it is in the best interests of Fund
    shareholders to do so based on existing market conditions or otherwise, the
    manager may change, or temporarily deviate from, the Master Fund's
    investment strategy and the manner in which the strategy is implemented.

Management Fees, page 32

    Response: Agreed. The first sentence under "Management Fees" on page 32 has
been revised as follows (new text is underlined):

    The Master Fund has agreed to pay an annual fee based on its average daily
    assets, as calculated daily, for the services and facilities provided by
    the manager, payable on a monthly basis, according to the following
    schedule:

Gresham Performance Record, page 33

42. Comment: Please disclose whether and to what extent Nuveen Asset Management
has any experience similar to what it will be conducting as the "Collateral
Subadvisor."

    Response: Agreed. The following disclosure relating to the collateral
subadvisor's experience has been added at the end of the final paragraph under
"Background and Personnel" on page 31:

    Effective January 1, 2005, Nuveen Advisory Corp. and Nuveen Institutional
    Advisory Corp. (prior thereto, each a separate investment advisory
    subsidiary of Nuveen Investments) were reorganized into Nuveen Asset
    Management. The collateral subadvisor and its predecessors have been
    providing investment advice to mutual funds, closed-end funds and/or other
    institutional and retail clients since 1976. As of December 31, 2005, the
    collateral subadvisor had approximately $61 billion in assets under
    management. The collateral subadvisor is comprised of two seasoned
    investment teams: a Chicago-based municipal fixed income team and a



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 16

    Los Angeles-based taxable fixed income team. The taxable fixed income team
    has worked together since 2000 (including time at other firms) with senior
    professionals averaging over 17 years of investment experience. The team
    has diverse and extensive experience in credit research, economic analysis,
    financial engineering and risk management. The collateral subadvisor's
    taxable fixed income team manages assets in several different strategies
    including multistrategy short-term, multistrategy core plus, high yield,
    emerging markets debt, and alpha transport. The Master Fund's collateral
    will be invested in short duration investment grade debt instruments,
    including obligations issued or guaranteed by the U.S. government, its
    agencies and instrumentalities; corporate obligations; and asset-backed
    securities. Such instruments are common investments for the collateral
    subadvisor in several of its investment strategies.

43. Comment: Please include the current NAV for the trading program as well as
definitions of the terms "drawdown," "peak-to-valley drawdown," and "notional
assets."

    Response: Agreed. The requested information has been included in the
prospectus.

Conflict of Interests, page 36

44. Comment: We note that there are no formal resolutions of conflicts
procedures. We also note that there are present and potential future conflicts
of interests in the Fund's structure and operation. As such, please revise to
indicate how you intend to resolve these conflicts.

    Response: See response to Comment 47 below.

45. Comment: Please refrain from using terms such as "theoretically,"
"occasionally," and "from time to time" to discuss when and whether conflicts
of interest may occur. We note that you have no operating history to use a
basis for these determinations, and these terms tend to mitigate the risk posed
by the conflicts presented.

    Response: Agreed. Those terms have been removed.

Conflicts Relating to the Commodity Subadvisor, page 36

46. Comment: Please revise to briefly describe the legal restrictions on the
combined size of specific commodity interests positions that may be taken for
all accounts managed by the commodity subadvisor.

    Response: Agreed. The requested information has been added on page 36 under
"Conflicts Relating to the Commodity Subadvisor."



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 17

47. Comment: Please disclose information pertaining to the "allocation
methodology" referred to on page 15 that the Subadvisor must use if it is
simultaneously effecting transactions of the same commodity interest for two or
more customers.


    Response: Agreed. When orders are combined, and it is not possible to
receive the same execution price, the commodity subadvisor utilizes average
pricing when allocating executed orders among accounts where possible. The
effect of the average price may operate on some occasions to the disadvantage
of the Master Fund. Where it is not possible to use average pricing, the
commodity subadvisor will allocate executed orders in accordance with a
systematic methodology that is designed to assure equitable treatment of all
accounts over time. The effect of using this methodology may operate on some
occasions to the disadvantage of the Master Fund. Appropriate language has been
added on page 37.


Conflicts Relating to the Manager and the Commodity Subadvisor, page 37

48. Comment: Where you discuss the ability of principals and other affiliates
of the pool to invest for their own accounts, please clarify whether you are
referring to investments in the pool or investments in futures contracts and
other commodity interests that the Master Fund will make. If it's the former,
please advise us as to how you intend to ensure that insiders who have access
to information regarding specific trades made by the Master Fund which will not
be available to the market will not trade on this information.

    Response: Agreed. Additional disclosure has been added on page 37.

No Formal Resolution of Conflicts Procedures, page 31

49. Comment: Please remove the final two sentences under this heading. The
prospectus should contain a discussion of the known material risk factors that
investors face. With respect to the last sentence, if you choose to encourage
investors to consult their own legal or tax professionals, please revise to
indicate this.

    Response: Agreed. The above-noted risk has been deleted.

Investment Policies of the Master Fund, page 39

50. Comment: We note that the Master Fund will invest only in commodity
interests that are traded in sufficient volume to permit ease of taking and
liquidating positions. Please revise to describe the criteria the Manager will
use to determine if a commodity interest has sufficient volume.



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 18

    Response: Agreed. The following sentence has been added on page 39 at the
end of the paragraph under "Liquidity":

    Sufficient volume includes only those futures and forward contracts that
    trade at least 200,000 contracts per year and that are in the top three of
    their respective commodity groups by a measure that includes trading volume.

Leverage, page 39

51. Comment: Please revise to clarify whether there are any limitations on the
amount you may employ.

    Response: Agreed. The following sentence has been added as the first
sentence under "Leverage":


    Although the Master Fund has no current intention to utilize leverage (and
    subject to the specified limitation noted below), the Master Fund may
    utilize leverage through the issuance of its preferred units and/or
    borrowings. The Master Fund (and the Fund) may not utilize leverage in an
    amount exceeding 33% of the Master Fund's capital after such leverage.


Description of Funds Shares and The Master Fund Units, page 40

Transfer Agent and Registrar, page 41

52. Comment: Please disclose the fees to be paid to the transfer agent. In this
regard, we note that you will be responsible for the fees charged by the
transfer agent.

    Response: Agreed. The Master Fund will be responsible for the Fund's
transfer agency fees in the estimated amount of 0.04% of the Master Fund's
total assets per year. This information has been included on page 41 under
"-Transfer Agent and Registrar." The transfer agency fees are included in
"Operating Expenses" in the break-even table.

Distributions, page 41

53. Comment: Please revise to indicate whether there are any restrictions that
may prevent the Master Fund from making distributions to the Fund or the Fund
making distributions to the Shareholders. In addition, please provide examples
of when the Master Fund and the pool may not make distributions.



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 19

    Response: Agreed. The following sentence has been added as the final
sentence in the paragraph before "Net Asset Value":

    The Master Fund will make distributions to the Fund (and the Fund will in
    turn make distributions to its shareholders) so long as the fair value of
    the Master Fund's assets generally exceed its liabilities.

54. Comment: Please clarify your statement that, "Over time, the Master Fund
and the Fund will distribute all of their net earnings." If this refers to the
distribution policies that will be followed by the Master Fund and the pool at
a later date, please expand your disclosure to indicate at what point in time
this would occur and what circumstances could cause the Master Fund and the
pool not to distribute all of their net earnings.

    Response: The above-noted sentence has been deleted. Additional disclosure
has been added to clarify the terms of the Fund's distribution policy.

Net Asset Value, page 42

55. Comment: Please clarify why you believe that prices reported at the
beginning and end of trading day should be used "for informational purposes."
Since any exchange trading of your units that will occur will not be made with
the benefit of knowing the pool's investment portfolio at any given time,
please explain the import of these trades to investors.

    Response: In response to your comment, the second, third and fourth
paragraphs under "Net Asset Value" have been deleted.

56. Comment: We refer to your disclosure of an "approximate value" of the
pool's shares that may not be calculated in the same manner as the NAV. Please
disclose the following with respect to the "approximate value:"

    .  Who will calculate the "approximate value;"
    .  Where this value may be accessed by investors;
    .  How often the value will be updated during the trading day;
    .  What investments will be excluded in determining the value (i.e.
       non-exchange traded forward contracts, swaps, etc.).; and,
    .  Whether this value will include any purchases of futures contracts
       during the trading day or whether it only reflects the current prices of
       interests held as of close of business of the previous trading day.

    Response: In response to your comment, the second, third and fourth
paragraphs under "Net Asset Value" have been deleted.

57. Comment: We note that NAV per Master Fund Unit is computed by dividing the
value of all assets of the Master Fund by the total number of Master Funds
Units Outstanding. Please revise



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 20

to briefly describe the guidelines that the commodity subadvisor will use to
value put options, swap contracts and other off-exchange commodity interests.

    Response: The last two sentences of the current third paragraph under "Net
Asset Value" has been revised as follows (new text is underlined):


    In such circumstances, THE MASTER FUND WILL USE AN INDEPENDENT PRICING
    SERVICE TO VALUE SUCH INVESTMENTS. The commodity subadvisor will REVIEW THE
    VALUES AS DETERMINED BY THE INDEPENDENT PRICING SERVICE AND DISCUSS THOSE
    VALUATIONS WITH THE PRICING SERVICE IF APPROPRIATE BASED on pricing
    oversight guidelines established by the MANAGER THAT IT BELIEVES ARE
    consistent with industry standards.


Use of Proceeds, page 43

58. Comment: Please revise to include organization and offering expenses and
underwriting commissions to be paid.

    Response: Agreed. The requested information has been added on page 43.

Underwriters, page 44

59. Comment: Please identify all underwriters known to you that will
participate in the initial offering as of the time of effectiveness of this
registration statement. In this regard, we note your disclosure on the cover
page of the prospectus that Nuveen Investments LLC will serve as an underwriter.


    Response: Agreed. The manager is currently in discussions with potential
lead underwriters for the Fund. As a result, the requested information will be
included in the registration statement as soon as it is available.


60. Comment: Please revise to identify the underwriters that may engage in
electronic distribution of your prospectus. Also, please advise us how your
procedures for the electronic distribution of your prospectus comply with
Section 5 of the Securities Act. In particular, please provide your analysis of
how you or the underwriters will provide investors with a prospectus that
satisfies the prospectus delivery requirements. In addition, please describe
the following to us in more detail:

    .  The communications used;
    .  The manner of conducting the distribution and sale, such as the use of
       indications of interest or conditional offers; and
    .  The funding of an account and payment of the purchase price.

Your analysis should address the communications made during the pre-effective
and post-effective periods. If the underwriters' procedures for electronic
distribution have already



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 21

been approved by the staff, please confirm that the procedures have not changed
since the time of our approval.


    Response: As noted above, the manager is currently in discussion with
potential lead underwriters for the Fund. The requested information will be
provided to the staff as soon as it is available.


61. Comment: Tell us whether you or the underwriters have any arrangements with
a third party to host or access your preliminary prospectus on the Internet. If
so, identify the party and the website, describe the material terms of your
agreement and provide us with any written agreement. Provide us also with
copies of all information concerning your company or prospectus that appeared
on their website. If you subsequently enter into any such agreements, promptly
supplement your response.


    Response: As noted above, the manager is currently in discussion with
potential lead underwriters for the Fund. The requested information will be
provided to the staff as soon as it is available.


62. Comment: Please provide us with a draft underwriting agreement when
available.


    Response: As noted above, the manager is currently in discussion with
potential lead underwriters for the Fund. A draft underwriting agreement will
be provided to the staff as soon as it is available.


63. Comment: We note your reference to the lockup agreement you have among the
Fund, the Master Fun[d] and the Subadvisors. Please disclose whether they
intend to participate in the offering and, if so, whether they will purchase
shares at the offering price or at a discount.


    Response: Agreed. Neither the Fund, the Master Fund nor the subadvisors
will purchase shares of the Fund in the initial public offering. Thereafter,
shares may only be purchased in the secondary market at market value. The
requested information has been added on page 44.


64. Comment: We note that the underwriting agreement may be terminated in the
event that "trading in the Fund's Shares shall have been suspended by the
Securities and Exchange Commission." Since there is no trading market for your
shares and will not be a market until after the registration statement is
brought effective, please explain why this provision has been included.


    Response: Although the manager has not selected a lead underwriter for the
Fund and does not have a draft underwriting agreement, the Fund expects the
agreement to contain such a provision as it is a standard provision in
underwriting agreements. It is expected that the Fund will enter into an
underwriting agreement with such a provision on the date that the Fund's
registration statement is declared effective by the Commission and that the
Fund's shares will begin trading on the American Stock Exchange on the next
business day. The closing of the offering is expected to occur approximately
three business days after effectiveness of the registration statement so there
will be a time period during which the common shares will trade prior to the
closing of the offering. It is during this time period that the underwriting
agreement may be terminated if "trading in the Fund's shares shall have been
suspended by the SEC."

Operation, page 48

65. Comment: Please revise to discuss your liquidity on a short term and long
term basis.

    Response: Agreed. The penultimate sentence of the first paragraph under
"Liquidity and Capital Resources" has been revised as follows (new text is
underlined):

    A significant portion of the Master Fund's net assets are expected to be
    held in debt instruments and instruments permitted by the CFTC for
    investment of customer segregated or secured amount funds by a futures
    commission merchant, substantially all of which will be highly liquid.

Credit Risk, page 49

66. Comment: In order to give depth to your disclosure, please revise to
disclose the percentage of your assets that you intend to invest in
off-exchange or over-the-counter commodity interests with a counterparty.


    Response: Agreed. As noted in comment 24, the following language has been
added on page 20 and throughout the document:


    The Master Fund does not expect that more than 5% of the Master Fund's net
    assets will be used to purchase OTC commodity put options, although the
    value of the commodities underlying these OTC commodity put options may
    represent up to 100% of the notional value of the Master Fund's commodity
    investments.

Declaration of Trust and LLC Agreement, page 51

Withdrawal or Removal of the Manager, page 53

67. Comment: We note that holders of an unspecified percentage of shares may
remove the Manager with or without cause. We also note that the Manager has no
obligation to call a Special Meeting even if holders of an unspecified
percentage of shares submit a written request for a Special Meeting. In light
of this, please disclose the procedures that shareholders would have to comply
with in order to remove the Manager.

    Response: The prospectus has been revised to state that the manager will
call a shareholder meeting upon the written request of at least a majority of
the shareholders.

Legal Opinion, page 57

68. Comment: Your statement under this heading that Bell, Boyd & Lloyd LLC will
not give investors legal advice tends to qualify the legal opinion that counsel
will be providing in



Mr. Owen Pinkerton
Securities and Exchange Commission
March 10, 2006
Page 23

connection with this offering. In addition, this language may imply that
investors cannot rely on either the legal or tax opinion. Please remove this
qualifying language.

    Response: Agreed. The above noted language has been deleted.

Where you can find more information, page 83

69. Comment: Please revise to update the address of the SEC's public reference
room to 100 F Street, N.E., Room 1580, Washington, D.C. 20549.

file with the SEC and the reports that will be provided to shareholders
pursuant to CFTC rules.

    Response: Agreed.

Part Two: Statement of Additional Information

71. Comment: Please include your financial statements in Part One of the
registration statement.

    Response: Agreed. The financial statements, to be included in a subsequent
filing, will be included in Part One of the registration statement.

Supplemental Performance Table, page 79

72. Comment: We refer to your statement that the "Table has been presented
based upon the amount of funds that would have been committed to the trading
program by a nonaffiliated client." In light of this, please tell us why you do
not consider the supplemental performance table to constitute hypothetical
performance data instead of extracted performance data.

    Response: Agreed. The supplemental performance tables are being prepared
and the statements explaining them will be incorporated in a subsequent filing.
We expect to have a number of performance tables that will show both pro forma
adjustments to the commodity subadvisor's performance and hypothetical
performance tables that will show adjustments to historical performance as it
is affected by the integrated investment strategy.

73. Comment: We refer to number 9 under this heading where you state that the
table will include annual management fees of 1 percent. Please advise us as to
whether that will be consistent with the management fee to be paid in the
proposed offering.

    Response: The table has been revised to reflect a 1.25% management fee (the
highest expected management fee that may be charged by the manager).

Appendix A

74. Comment: Please include this information in Part One of the registration
statement where you discuss the trading policies of Gresham and the Master Fund.

    Response: Agreed. The information contained in Appendix A has been moved to
page 22 under "Overview of Commodity Investment Strategy and Integrated
Investment Strategy."

Part II

75. Comment: Please explain why the Director and Principal Executive Officer of
Nuveen Commodities Asset Management, LLC has signed this registration statement
rather than Nuveen Commodities Income and Growth Master Fund LLC.


    Response: The signature page has been revised to reflect the signature of
Mr. Amboian on behalf of the Fund and the Master Fund in his capacity as an
officer of Nuveen Commodities Asset Management, LLC, the manager of the Master
Fund, and pursuant to delegated authority from the current sole trustee of the
Fund.


Item 16. Exhibits and Financial Statement Schedules

76. Comment: Please file the legal and tax opinions with the next amendment or
provide drafts for us to review. We must review the opinions before we can
declare your registration statement effective and we may have comments on the
opinions.

    Response: Agreed. The opinions will be provided to the staff as soon as
they are available.

Item 17. Undertakings

77. Comment: Please remove the undertakings found under (a) since these
undertakings relate to continuous offerings subject to Rule 415. Alternatively,
if such undertakings are included for use by an affiliate of the Fund in
market-making transactions, please note this in the footnotes to the fee table
and in the "Underwriting" section of the prospectus, or include alternate pages
to the registration statement to be used as a "market-making prospectus." If
you do intend to use this prospectus or an alternate prospectus for
market-making activities, please note that the undertakings required under
Item 512(a) have been revised as of December 1, 2005.

    Response: Agreed.
