    Rule 485(a) Filings of October 27, 2004 and December 13, 2004 correspondence

Dear Brion: The following is in response to our telephone conversation regarding
your comments on the filings and correspondence referenced above.

Comment 1- All Funds - Prospectus and SAI - Valuation of Shares
Make the prospectus and SAI disclosure regarding valuation procedures more
specific to the type of fund and address specific circumstances requiring fair
valuation. Response - Valuation of Shares section of the prospectus has been
rewritten (see attached). Non applicable language in the Net Asset Value section
of the SAIs has been deleted (see attached).

Comment 2 - All Funds - Prospectus - Excessive Trading
Please provide support for a) right to cancel or reject a purchase order under
Section 22(e) and Rule 22c-1 and b) right to delay exchange. Response - Right to
reject an order: Section 22(e) of the Investment Company Act prohibits an
investment company from suspending the right to redeem shares, except in
circumstances prescribed by the Commission. Rule 22c-1 does not address the
question of the right to restrict, reject or terminate any order, it merely
governs the price at which purchase and redemption orders are processed.

The fund is not suspending under any circumstances the right to redeem shares. A
shareholder has the right to redeem shares at any time. Section 22(e) does not
prohibit an investment company from suspending the right to purchase shares. In
fact, there is nothing in the Investment Company Act, which requires an
investment company to accept any purchase order. The Act establishes
requirements on how an investment company treats accepted purchase orders, that
is they must be priced on the basis of the next determined net asset value;
however, an investment company is free to reject any order or to cancel an order
if subsequent to its processing it is determined to be contrary to the fund's
policies. To suggest otherwise would be to deny an investment company




any  means of  combating  market  timing  or  excessive  trading  in the  funds,
preventing  the  use of  funds  for  money  laundering  or  implementing,  where
required, any suitability analysis.  Since an exchange order entails in effect a
simultaneous  purchase and  redemption  request,  the issue  arises  whether the
rejection or  cancellation  of an exchange order is equivalent to the suspension
of a redemption right. We believe that the better position is that the rejection
or cancellation of an exchange order does not have that effect; rather, in order
for the exchange order to be in good order and capable of acceptance, both parts
of the transaction must be appropriate for processing.  The opposite conclusion,
that the  redemption  must be processed  although the purchase is rejected,  may
result in  consequences  that are  disadvantageous  to the  investor.  With this
approach an investor always has the ability to require a redemption by placing a
redemption  order. If an investor is more concerned with the redemption  portion
of the transaction than the reinvestment, an investor may instead of an exchange
order place concurrent purchase requests for the new fund and redemption request
for the current fund. To clarify the investors rights,  appropriate language has
been added (See attached).

Right to delay Exchange: In a no-action letter to the Investment Company
Institute, dated November 13, 2002, the staff of the Commission agreed that an
investment company may effectuate exchanges on a delayed basis in order to seek
to prevent market timing in the fund. Section 11(a) generally makes it unlawful
for any fund or its principal underwriter to make an exchange offer for the
shares of another fund on any basis other than the relative net asset value of
the respective securities to be exchanged. Under Section 11(a), the net asset
value used must be the price used for public sale of the shares either (i) at
the time of receipt of the exchange offer or (ii) at such later time specified
in the offer. The staff in the ICI letter agreed that a fund could, consistent
with Section 11(a) make an exchange offer on a specified delayed basis, so long
as the terms are fully and clearly described in the prospectus.

The ICI no-action letter provided two examples of delayed exchanges but did not
suggest that such arrangements were those exclusively available in compliance
with Section 11(a). We also respectively suggest that, as the Commission has
indicated that it is incumbent upon investment companies to implement procedures
to seek to effectively prevent market timing, the staff of the Commission must
likewise be flexible in applying its interpretive positions in order to permit
the investment company to fulfill that preventative mandate, particularly where
the proposed action does not benefit the management company and is being
implemented in the best interests of shareholders of the fund.

The prospectus is clear as to the terms of the exchange offer. Under normal
circumstances, the exchange is affected at the net asset value next determined
following receipt of the exchange order. However, the fund can implement the
exchange at the relative net assets value one the following business day if that
would be in the best interests of the fund. In the context of the discussion of
excessive trading and market timing, the circumstances in which the fund may
exercise this right is clear. The prospectus has been modified to make this
context clearer (See attached).




We believe that the prospectus disclosure regarding the exchange privilege meets
the standards of Section 11(a) and the ICI no action letter and represents a
reasonable compromise in providing the individual investor with a clear
statement of that investor's rights while seeking to protect the collective
interests of shareholders of the fund.

Comment 3 - All Funds - Prospectus - Limitations on exchange activity Provide
explanation for exceptions to the exchange limitation policy. Response -
Appropriate language has been added (See attached).

Comment 4 - All Funds - Prospectus - Excessive trading risk
Since these are tax-free funds, the inclusion of disclosure regarding foreign
securities or small cap equity securities is inappropriate. Revise and include
disclosure appropriate to the nature of the fund's investments. Response -
Appropriate changes have been made (See attached).

Comment 5 - All Funds - Prospectus - Reference to SAI disclosure
Provide the statement called for by Item 4(d) of Form N-1A. Response -
Appropriate language has been added to the back cover of Prospectus in the "For
more Information section" (See attached).

Comment 6 - All Funds - SAI - Portfolio Holdings Disclosure Issue A - For all of
these disclosures, must address (a) frequency and time lag, (b) monitoring, (c)
manner of oversight and (d) why in best interest of fund. Issue B - Disclose,
pursuant to Item 11(f)(1)(v) the persons authorized to release the disclosure
(CCO) Issue C - Disclose whether each category of disclosure is ongoing, and if
so add the disclosure required by Item 11(f)(2) Issue D - Affiliated persons-
Provide disclosure regarding the procedures relating to provision of portfolio
holdings information to affiliate. Response - Disclosure has been redone to
accommodate all comments (See attached)

Comment # 7:  High Yield Municipal Bond Fund
Please address our concern that having the High Yield Municipal Bond Fund as a
series of the Tax-Free Bond Trust is misleading to the shareholders. Response -
We do not feel that this is misleading to the shareholders. The investment
policy of the High Yield Municipal Bond Fund is clearly spelled out in both the
prospectus and the Statement of Additional Information. Please note that the
fact that the Fund is a series of the Tax-Free Bond Trust is only mentioned in
the introduction to the SAI.



TRANSACTION POLICIES

Valuation of shares The net asset value (NAV) per share for each fund and class
is determined each business day at the close of regular trading on the New York
Stock Exchange (typically 4. P.M. Eastern time). Each fund generally values its
portfolio of municipal securities and other investments using closing market
prices or readily available market quotations. When closing market prices or
market quotations are not available or are considered by the Adviser to be
unreliable, a fund uses a security's fair value. Fair value is the valuation of
a security determined on the basis of factors other than market value in
accordance with procedures approved by the Board of Trustees. All methods of
determining the value of a security, including those discussed below, on a basis
other than market value, are forms of fair value. The use of fair value pricing
by a fund may cause the net asset value of its shares to differ from the net
asset value that would be calculated only using market prices. For market prices
and quotations, as well as some fair value methods, the fund relies upon
securities prices provided by pricing services. Certain types of securities,
including many municipal securities, are regularly priced using fair value
rather than market prices. The funds' pricing service may use a pricing matrix
to determine the value of municipal securities that do not trade daily. A
pricing matrix is a means of valuing a municipal or other debt security on the
basis of current market prices for other debt securities and historical trading
patterns in the market for fixed income securities. Portfolio securities may
trade on days when the New York Stock Exchange is closed, even though the funds'
shares will not be priced on those days. The fund values debt securities with
remaining maturities of 60 days or less at amortized cost. For more information
on the valuation of shares, please see the Statement of Additional Information.

Buy and sell prices When you buy shares, you pay the NAV plus any applicable
sales charges, as described earlier. When you sell shares, you receive the NAV
minus any applicable deferred sales charges.

Execution of requests Each fund is open on those days when the New York Stock
Exchange is open, typically Monday through Friday. Buy and sell requests are
executed at the next NAV to be calculated after Signature Services receives your
request in good order.

At times of peak activity, it may be difficult to place requests by phone.
During these times, consider using EASI-Line, accessing www.jhfunds.com, or
sending your request in writing.

In unusual circumstances, any fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to three business days
or longer, as allowed by federal securities laws.

Telephone transactions For your protection, telephone requests may be recorded
in order to verify their accuracy. Also for your protection, telephone
redemption transactions are not permitted on accounts whose names or addresses
have changed within the past 30 days. Proceeds from telephone transactions can
only be mailed to the address of record.

Exchanges You may exchange shares of one John Hancock fund for shares of the
same class of any other, generally without paying any additional sales charges.
The registration for both accounts involved must be identical.

Class B and Class C shares will continue to age from the original date and will
retain the same CDSC rate. A CDSC rate that has increased will drop again with a
future exchange into a fund with a lower rate. A fund may change or cancel its
exchange policies at any time, upon 60 days' notice to its shareholders. For
further details, see "Additional Services and Programs" in the SAI (see the back
cover of this prospectus).

Excessive trading The funds are intended for long-term investment purposes only
and do not knowingly accept shareholders who engage in "market timing" or other
types of excessive short-term trading. Short-term trading into and out of a fund
can disrupt portfolio investment strategies and may increase fund expenses for
all shareholders, including long-term shareholders who do not generate these
costs.

Right to reject or restrict purchase and exchange orders Purchases and exchanges
should be made primarily for investment purposes. The funds reserve the right to
restrict, reject or cancel, for any reason and without any prior notice, any
purchase or exchange order, including transactions representing excessive
trading and transactions accepted by any shareholder's financial intermediary.
For example, the funds may in their discretion restrict, reject or cancel a
purchase or exchange order even if the transaction is not subject to the
specific "Limitations on Exchange Activity" described below if the funds or
their agents determine that accepting the order could interfere with the
efficient management of a fund's portfolio or otherwise not be in the fund's
best interest in light of unusual trading activity related to your account. In
the event that the funds reject or cancel an exchange request, neither the
redemption nor the purchase side of the exchange will be processed. If you would
like the redemption request to be processed even if the purchase order is
rejected, you should submit separate redemption and purchase orders rather than
placing an exchange order. The funds reserve the right to delay for up to one
business day the processing of exchange requests in the event that, in the
funds' judgment, such delay would be in the funds' best interest, in which case
both the redemption and purchase side of the exchange will receive the funds'
net asset values at the conclusion of the delay period. The funds, through their
agents in their sole discretion, may impose these remedial actions at the
account holder level or the underlying shareholder level.

Exchange limitation policies The funds' Boards of Trustees have adopted the
following policies and procedures by which the funds, subject to the limitations
described below, take steps reasonably designed to curtail excessive trading
practices.

Limitations on exchange activity The funds, through their agents, undertake to
use their best efforts to exercise the



funds' right to restrict, reject or cancel purchase and exchange orders, as
described above, if an account holder, who purchases or exchanges into a fund
account in an amount of $5,000 or more, exchanges $1,000 or more out of that
fund account within 30 calendar days on three occasions during any 12-month
period. Nothing in this paragraph limits the right of the funds to refuse any
purchase or exchange order, as in the preceding paragraph.

Exchanges made on the same day in the same account are aggregated for purposes
of counting the number and dollar amount of exchanges made by the accountholder.
These exchange limits may be modified for accounts held by certain retirement
plans to conform to plan exchange limits, ERISA considerations or Department of
Labor regulations. Certain automated or pre-established exchange, asset
allocation and dollar cost averaging programs are not subject to these exchange
limits. These programs are excluded from the exchange limitation since the fund
believes that they are advantageous to shareholders and do not offer an
effective means for market timing excessive trading strategies. These investment
tools involve regular and pre-determined purchase or redemption requests made
well in advance of any knowledge of events effecting the market on the date of
the purchase or redemption. These exchange limits are subject to the funds'
ability to monitor exchange activity, as discussed under "Limitations on the
ability to detect and curtail excessive trading practices" below. Depending upon
the composition of a fund's shareholder accounts and in light of the limitations
on the ability of the funds to detect and curtail excessive trading practices, a
significant percentage of a fund's shareholders may not be subject to the
exchange limitation policy described above. In applying the exchange limitation
policy, the funds consider information available to them at the time and reserve
the right to consider trading activity in a single account or multiple accounts
under common ownership, control or influence.

Limitation  on the ability to detect and  curtail  excessive  trading  practices
Shareholders seeking to engage in excessive trading practices sometimes deploy a
variety of strategies to avoid detection,  and, despite the efforts of the funds
to prevent  their  excessive  trading,  there is no guarantee  that the funds or
their agents will be able to identify such shareholders or curtail their trading
practices.  The  ability  of the funds and their  agents to detect  and  curtail
excessive  trading  practices  may also be limited by  operational  systems  and
technological  limitations.  Because the funds will not always be able to detect
frequent  trading  activity,  investors should not assume that the funds will be
able to  detect  or  prevent  all  frequent  trading  or  other  practices  that
disadvantage the funds.  For example,  the ability of the fund to monitor trades
that are placed by omnibus or other  nominee  accounts  is  severely  limited in
those  instances  in which the  financial  intermediary,  including  a financial
adviser,  broker,  retirement plan  administrator or fee-based  program sponsor,
maintains the record of a fund's underlying beneficial owners.  Omnibus or other
nominee  account  arrangements  are common  forms of  holding  shares of a fund,
particularly among certain financial  intermediaries such as financial advisers,
brokers,  retirement plan  administrators or fee-based  program sponsors.  These
arrangements often permit the financial intermediary to aggregate their clients'
transaction  and  ownership   positions  and  do  not  identify  the  particular
underlying shareholder(s) to the fund.

Excessive trading risk To the extent that the funds or their agents are unable
to curtail excessive trading practices in a fund, these practices may interfere
with the efficient management of the fund's portfolio, and may result in the
fund engaging in certain activities to a greater extent than it otherwise would,
such as maintaining higher cash balances, using its line of credit and engaging
in portfolio transactions. Increased portfolio transactions and use of the line
of credit would correspondingly increase the fund's operating costs and decrease
the fund's investment performance, and maintenance of higher levels of cash
balances would likewise result in lower fund investment performance during
periods of rising markets.

To the extent that the fund invests in municipal securities, including below
investment grade (junk) bonds, that may trade infrequently or are fair valued as
discussed above under "Valuation of Shares," investors may seek to trade fund
shares in an effort to benefit from their understanding of the value of these
securities (referred to as price arbitrage). Any such frequent trading
strategies may interfere with efficient management of the fund's portfolio to a
greater degree than funds which invest in highly liquid securities, in part
because the fund may have difficulty selling these portfolio securities at
advantageous times or prices to satisfy large and/or frequent redemption
requests. Any successful price arbitrage may also cause dilution in the value of
the fund shares held by other shareholders.

Account information John Hancock Funds is required by law to obtain information
for verifying an account holder's identity. For example, an individual will be
required to supply name, address, date of birth and social security number. If
you do not provide the required information, we may not be able to open your
account. If verification is unsuccessful, John Hancock Funds may close your
account, redeem your shares at the next NAV minus any applicable sales charges
and take any other steps that it deems reasonable.

Certificated shares The funds no longer issue share certificates. Shares are
electronically recorded. Any existing certificated shares can only be sold by
returning the certificated shares to Signature Services, along with a letter of
instruction or a stock power and a signature guarantee.

Sales in advance of purchase payments When you place a request to sell shares
for which the purchase money has not yet been collected, the request will be
executed in a timely fashion, but the fund will not release the proceeds to you
until your purchase payment clears. This may take up to ten business days after
the purchase.

Eligibility by state You may only invest in, or exchange into, fund shares
legally available in your state.

                                       1


NET ASSET VALUE

For purposes of calculating the net asset value ("NAV") of the Fund's shares,
the following procedures are utilized wherever applicable.

Debt investment securities are valued on the basis of valuations furnished by a
principal market maker or a pricing service, both of which generally utilize
electronic data processing techniques to determine valuations for normal
institutional size trading units of debt securities without exclusive reliance
upon quoted prices. In addition, because of the amount of time required to
collect and process trading information as to large numbers of securities
issues, the values of certain securities (such as convertible bonds, U.S.
government securities and tax-exempt securities) are determined based on market
quotations collected prior to the close of the Exchange. Occasionally, events
affecting the value of such securities may occur between the time of the
determination of value and the close of the Exchange which will not be reflected
in the computation of the Fund's net asset value. If events materially affecting
the value of such securities occur during such period, then these securities
will be valued at their fair value following procedures approved by the
Trustees.



Short-Term debt investments which have a remaining maturity of 60 days or less
may be valued at amortized cost which approximates market value. If market
quotations are not readily available or if in the opinion of the Adviser any
quotation or price is not representative of true market value, the fair value of
the security may be determined in good faith in accordance with procedures
approved by the Trustees.


If any securities held by the Fund are restricted as to resale, the fair value
of such securities is generally determined as the amount which the Fund could
reasonably expect to realized from an orderly disposition of such securities
over a reasonable period of time. The valuation procedures applied in any
specific instance are likely to vary from case to case. However, consideration
is generally given to the financial position of the issuer and other fundamental
analytical data relating to the investment and to the nature of the restrictions
on disposition of the securities (including any registration expenses that might
be borne by the Fund in connection with such disposition). In addition, specific
factors are also generally considered, such as the cost of the investment, the
market value of any unrestricted securities of the same class, the size of the
holding, the prices of any recent transactions or offers with respect to such
securities and any available analysts' reports regarding the issuer.



The NAV for each class of the Fund is determined  each business day at the close
of regular trading on the New York Stock Exchange  (typically 4:00 p.m.  Eastern
Time) by dividing a class's net assets by the number of its shares  outstanding.
Trading of fixed income securities may take place on Saturdays and U.S. business
holidays  on which the Fund's NAV is not  calculated.  Consequently,  the Fund's
portfolio  securities may trade and the NAV of the Fund's redeemable  securities
may be  significantly  affected on days when a shareholder  has no access to the
Fund.

APPENDIX E


               Description of Portfolio Holdings Disclosure Policy

General. The Board of Trustees has adopted a policy that governs when and by
whom portfolio holdings information may be provided to investors, service
providers to the fund or market participants. It is the policy of the fund to
provide nonpublic information regarding fund's portfolio holdings only in the
limited circumstances permitted by the policy and only where there is a
legitimate business purpose for providing the information. The policy applies to
the officers of the fund, the adviser, any subadviser, John Hancock Funds, its
affiliates and their employees. This is a summary of the fund's policy. The
Board of Trustees has approved this policy and must approve any material
changes. In doing so, the Board has concluded that the limited circumstances
where disclosure of non-public information is permitted are in the best
interests of the fund. Under no circumstances may any person receive
compensation for providing non-public information regarding the fund's holdings
to any person.

     The Board  has  delegated  to the  Chief  Compliance  Officer  ("CCO")  the
responsibility for monitoring the fund's and the Adviser's  compliance with this
policy.  The CCO is required to report any material  issues that may arise under
the policy or  disclosure  in violation of this policy to the Board of Trustees.
If the fund or another party subject to this policy desire to provide  portfolio
information that has not already been made public to a Nonaffiliated  Person (as
defined below), the CCO determines if the interests of the fund and the services
providers  may be in  conflict  in  determining  whether  to  supply  that  such
information. If the CCO determines that no conflict exists, the Board or the CCO
may authorize release of the information.  If the CCO determines that a conflict
exists, the CCO refers the conflict to the Board of Trustees.

         The following defined terms are used in the policy and this summary.

Nonpublic Information. Portfolio holdings are considered Nonpublic Information
until such holdings are posted on a publicly available website which is
disclosed in the fund prospectus or until filed with the SEC via Edgar on either
Form N-CSR or Form N-Q.

"Affiliated Persons" are: (a) persons affiliated with the Funds, (b) the Funds'
investment adviser or principal underwriter or any affiliate of either entity,
(c) the investment adviser's ultimate parent, Manulife Financial Corporation
("MFC") or any affiliate thereof, (d) in the case of a particular Fund
portfolio, the subadviser to the portfolio, or any affiliate of the subadviser,
(e) the Funds' custodian and (f) the Funds' certified public accountants.

"Nonaffiliated Persons" is any person who is not an Affiliated Person.



Public Disclosure. The Funds' portfolio holdings are disclosed in publicly
available filings with the SEC (e.g. Form N-CSR or Form N-Q). The Funds also
publish the following information on their website jhfunds.com:

(1)      On the fifth business day after month-end, the following information
         for each fund will be posted on www.jhfunds.com: top ten holdings (% of
         each position); top ten sector analysis; total return/yield; top ten
         countries/SIC; average quality/maturity; beta/alpha/r2 (open-end funds
         only); top ten portfolio composition

(2)      The following information regarding portfolio holdings will be posted
         on www.jhfunds.eom each month on a one-month lag (i.e., information as
         of December 31 will be posted on February 1): security name; cusip;
         market value; shares/amount; coupon rate; maturity date

(3)      With respect to Money Market Fund and U.S. Government Cash Reserve, the
         following information regarding portfolio holdings will be posted
         weekly on www.jhfunds.com: net assets; seven day yield; thirty day
         yield; % maturing in last seven days; portfolio breakdown by securities
         type; weighted average maturity


Disclosure of Portfolio Holdings to Nonaffiliated Persons

         Subject to monitoring by the CCO, persons subject to the policy may

information that falls in this category.




Disclosure of Portfolio Holdings to Affiliated Persons

     Certain affiliated persons of the fund or its service providers need access
to Non-Public information regarding portfolio holdings in order to provide their
services to the fund. For example,  employees of the Adviser or a subadviser who
provide  portfolio  management  or  administrative  services  to the funds  need
current access to portfolio holdings to perform those services. Accountants need
access to portfolio holdings in performing audits. In addition, some persons who
work for the affiliates of the adviser may need access to Non-Public information
to perform their roles. For example,  risk management personnel of the Adviser's
parent, may need to know the portfolio holdings in order to evaluate whether the
Adviser's  internal  controls  are  being  properly   implemented  or  designed.
Generally,  affiliated  persons that have access to Non-Public  Information  are
provided  that  information  without  time lag and  with  such  frequency  as is
necessary to perform their duties, which frequently is daily. The following is a
list of the  categories  of  affiliated  persons  who  may be  given  access  to
portfolio holdings.

     o    The Adviser or any subadviser and their employees.
     o    The fund's custodian,  fund accounting agent or other agent (and their
          employees) who require  information in order to provide their assigned
          services to the fund.
     o    The fund's  certified  public  accounting  firm and its  employees who
          provide audit or other services to the fund.
     o    Manulife,  its  affiliates and any of their  employees,  to the extent
          such   entities  or  persons  are  acting  in  a  legal,   accounting,
          compliance,  internal control or supervisory  capacity but only to the
          extent  that such  access is required  to enable  those  employees  to
          perform their assigned duties which do not conflict with the interests
          of the fund.

              The entities listed above must provide the CCO with assurances
that their employees will keep any Non-Public Information confidential. As with
any of the fund's policies, the CCO is charged with reviewing its implementation
and evaluating periodically if it is reasonably designed to comply with the
federal securities laws. The CCO will, in that process, consider whether the
access outlined above to Affiliated Persons continues to be appropriate.

              The CCO may authorize the provision of any Nonpublic Information
regarding portfolio holdings to other Affiliated Persons, but must report such
approval to the Board of Trustees.
