Dear Ms. Mengiste:

This letter responds to your comment received by telephone on March 5, 2009 for
the N-14 filings referenced above. The comment and response are outlined below:

COMMENT: Describe how an accounting survivor was determined applying the NAST
factors.

RESPONSE: At meetings of the Funds' Boards of Directors/Trustees in December
2008 and January 2009, RiverSource Investments, LLC, the investment manager for
each of the Buying Funds and the Selling Funds in the proposed reorganizations,
presented relevant information that, in each case, demonstrates that the Buying
Fund is the proper accounting survivor with respect to the proposed
reorganization based upon the guidance of



                                                                     Page 2 of 6


the Commission Staff in North American Security Trust (pub. avail. August 5,
1994). In North American Security Trust, the Staff stated that it would not
recommend enforcement action in accordance with Rule 482 under the Securities
Act of 1933, as amended, or Rule 34b-1 under the Investment Company Act of 1940,
as amended, if an investment company formed as a result of merging three
investment companies advertised its historical performance using, for periods
prior to the reorganization, the performance data of the predecessor investment
company that it most closely resembled. The Staff stated that, in determining
whether any predecessor investment company resembles a new or surviving
investment company closely enough to justify the use of the predecessor
investment company's performance, the factors to be considered are the
investment companies': (i) investment advisers; (ii) investment objectives,
policies, and restrictions; (iii) expense structures and expense ratios; (iv)
asset sizes; and (v) portfolio compositions. The Staff also stated that the
survivor of a business combination for accounting purposes (i.e., the investment
company whose financial statements are carried forward) would typically be the
investment company whose historical performance may be used by a new or
surviving investment company. We understand that the factors used by accountants
to determine the accounting survivor of a business combination are essentially
identical to those articulated by the Staff in North American Security Trust.

Applying the North American Security Trust factors to the proposed
reorganizations strongly suggests that, in each case, the Buying Fund would be
considered the accounting survivor for each proposed reorganization:

PROXY BOOK 1

PROPOSAL 1: Proposed reorganization of RiverSource Global Technology Fund
            (Selling Fund) into Seligman Global Technology Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and portfolio managers, and the same investment objective, policies and
restrictions as the Buying Fund. Although the investment portfolio for both the
Buying Fund and the Selling Fund are currently managed by the same portfolio
managers, their tenure with the Buying Fund is longer than with the Selling
Fund. Prior to the reorganization, the expense structure of the Buying Fund will
be changed to be consistent with the other funds in the RiverSource family of
funds, including the Selling Fund. However, at the time of reorganization, the
expense structure of the combined fund will more closely resemble that of the
Selling Fund based upon the length of time the expense structure has been in
place. Based on net assets at Oct. 31, 2008, the net asset level of the Buying
Fund is greater than that of the Selling Fund. Therefore, the net asset level of
the combined fund is expected to more closely resemble that of the Buying Fund.
The portfolio composition of the combined fund is expected to more closely
resemble that of the Buying Fund than that of the Selling Fund. The investment
manager therefore believes that the totality of the factors discussed above,
taken together, suggest that the combined fund will more closely resemble the
Buying Fund, and that the Buying Fund is thus the proper accounting survivor of
the proposed reorganization.

PROPOSAL 2: Proposed reorganization of RiverSource Growth Fund (Selling Fund)
            into Seligman Growth Fund, Inc. (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and portfolio manager, and the same investment objective, policies and
restrictions as the Buying Fund. Although the investment portfolio for both the
Buying Fund and the Selling Fund are currently managed by the same portfolio
manager, his tenure with the Buying Fund is longer than with the Selling Fund.
Prior to the reorganization, the expense structure of the Buying Fund will be
changed to be consistent with the other funds in the RiverSource family of
funds, including the Selling Fund. However, at the time of reorganization, the
expense structure of the combined fund will more closely resemble that of the
Selling Fund based upon the length of time the expense structure has been in
place. Based on net assets at Oct. 31, 2008, the net asset level of the Buying
Fund is less than that of the Selling Fund. Therefore, the net asset level of
the combined fund is expected to more closely resemble that of the Selling Fund.
The portfolio composition of the combined fund is expected to more closely
resemble that of the Buying Fund than that of the Selling Fund. The investment
manager therefore believes that the totality of the factors discussed above,
taken together, suggest that the combined fund will more closely resemble the
Buying Fund, and that the Buying Fund is thus the proper accounting survivor of
the proposed reorganization.



                                                                     Page 3 of 6


PROPOSAL 3: Proposed reorganization of RiverSource Large Cap Value Fund (Selling
            Fund) into RiverSource Equity Value Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and portfolio managers, and the same investment objective, policies and
restrictions as the Buying Fund. Although the investment portfolio for both the
Buying Fund and the Selling Fund are currently managed by the same portfolio
managers, their tenure with the Buying Fund is longer than with the Selling
Fund. At the time of reorganization, the expense structure of the combined fund
will more closely resemble that of the Buying Fund based upon the overall
expense ratio (excluding the impact of any performance incentive adjustment to
the management fee). Based on net assets at Oct. 31, 2008, the net asset level
of the Buying Fund is greater than that of the Selling Fund. Therefore, the net
asset level of the combined fund is expected to more closely resemble that of
the Buying Fund. The portfolio composition of the combined fund is expected to
more closely resemble that of the Buying Fund than that of the Selling Fund. The
investment manager therefore believes that the totality of the factors discussed
above, taken together, suggest that the combined fund will more closely resemble
the Buying Fund, and that the Buying Fund is thus the proper accounting survivor
of the proposed reorganization.

PROPOSAL 4: Proposed reorganization of RiverSource Small Cap Advantage Fund
            (Selling Fund) into Seligman Smaller-Cap Value Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and portfolio managers, and the same investment objective, policies and
restrictions as the Buying Fund. Although the investment portfolio for both the
Buying Fund and the Selling Fund are currently managed by the same portfolio
managers, their tenure with the Buying Fund is longer than with the Selling
Fund. Prior to the reorganization, the expense structure of the Buying Fund will
be changed to be consistent with the other funds in the RiverSource family of
funds, including the Selling Fund. However, at the time of reorganization, the
expense structure of the combined fund will more closely resemble that of the
Selling Fund based upon the length of time the expense structure has been in
place. Based on net assets at Oct. 31, 2008, the net asset level of the Buying
Fund is less than that of the Selling Fund. Therefore, the net asset level of
the combined fund is expected to more closely resemble that of the Selling Fund.
The portfolio composition of the combined fund is expected to more closely
resemble that of the Buying Fund than that of the Selling Fund. The investment
manager therefore believes that the totality of the factors discussed above,
taken together, suggest that the combined fund will more closely resemble the
Buying Fund, and that the Buying Fund is thus the proper accounting survivor of
the proposed reorganization.

PROXY BOOK 2

PROPOSAL 1(A) AND 1(B): Proposed reorganization (each a "Reorganization") of
                        either or both RiverSource Large Cap Equity Fund
                        (Selling Fund) and Seligman Common Stock Fund (Selling
                        Fund) into RiverSource Disciplined Equity Fund (Buying
                        Fund)

At the time of each Reorganization, the combined fund will have the same
investment manager and portfolio managers, and the same investment objective,
policies and restrictions as the Buying Fund. Although the investment portfolio
for the Buying Fund and each Selling Fund are currently managed by the same
portfolio managers, their tenure with the Buying Fund is longer than with each
Selling Fund. Prior to each Reorganization, the expense structure of Seligman
Common Stock Fund will be changed to be consistent with the other funds in the
RiverSource family of funds, including the Buying Fund. However, at the time of
each Reorganization, the expense structure of the combined fund will more
closely resemble that of the Buying Fund based upon length of time the expense
structure has been in place (compared to Seligman Common Stock Fund only), the
presence of a performance incentive adjustment (which is absent for Seligman
Common Stock Fund) and the overall expense ratio (compared to each of the
Selling Funds and excluding the impact of any performance incentive adjustment
to the management fee for RiverSource Large Cap Equity Fund). Based on net
assets at Oct. 31, 2008, the net asset level of the Buying Fund is less than
that of RiverSource Large Cap Equity Fund and greater than that of Seligman
Common Stock Fund. Therefore, the net asset level of the combined fund is
expected to more closely resemble that of the Selling Fund when compared to
RiverSource Large Cap Equity Fund but is expected to more closely resemble the
Buying Fund



                                                                     Page 4 of 6


when compared to Seligman Common Stock Fund. The portfolio composition of the
combined fund is expected to more closely resemble that of the Buying Fund than
that of each Selling Fund. The investment manager therefore believes that the
totality of the factors discussed above, taken together, suggest that the
combined fund will more closely resemble the Buying Fund, and that the Buying
Fund is thus the proper accounting survivor of each proposed Reorganization.

PROXY BOOK 3

PROPOSALS 1-14:

Proposed reorganization (each a "Reorganization") of any or all of:

     Seligman Colorado Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Florida Municipal Series, a series of Seligman Municipal Series
     Trust,

     Seligman Georgia Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Louisiana Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Maryland Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Massachusetts Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Michigan Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Missouri Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Inc.,

     Seligman Oregon Municipal Class, a series of Seligman Municipal Fund
     Series, Inc.,

     Seligman Pennsylvania Municipal Fund Series, and

     Seligman South Carolina Municipal Class, a series of Seligman Municipal
     Fund Series, Inc., (each a "Selling Fund"),

into Seligman National Municipal Class, a series of Seligman Municipal Fund
Series, Inc., (the "Buying Fund")

For each Reorganization, the combined fund will have the same investment
objective, policies and restrictions as the Buying Fund. Also, for each
Reorganization the investment manager and portfolio managers of the combined
fund will be the same as both the Buying Fund and the Selling Fund. For each
Reorganization, the expense structure of the combined fund will more closely
resemble that of the Buying Fund. For each Reorganization, except for the
combination of Seligman Michigan Municipal Class into the Buying Fund, the
combination of Seligman Ohio Municipal Class into the Buying Fund and the
combination of Seligman South Carolina Municipal Class into the Buying Fund, the
net asset level of the Buying Fund is greater than that of the Selling Fund,
based on net assets at Oct. 31, 2008. Therefore, the asset level of the combined
fund is expected to more closely resemble that of the Buying Fund except for the
combination of Seligman Michigan Municipal Class into the Buying Fund, the
combination of Seligman Ohio Municipal Class into the Buying Fund and the
combination of Seligman South Carolina Municipal Class into the Buying Fund. For
each Reorganization, the portfolio composition of the combined fund is expected
to more closely resemble that of the Buying Fund than that of the Selling Fund.
The investment manager therefore believes that the totality of the factors
discussed above, taken together, suggest that the combined fund will more
closely resemble the Buying Fund, and that the Buying Fund is thus the proper
accounting survivor of each proposed Reorganization.

PROXY BOOK 4

PROPOSAL 1(A): Proposed reorganization of Seligman Asset Allocation Aggressive
               Growth Fund (Selling Fund) into RiverSource Portfolio Builder
               Total Equity Fund (Buying Fund),

               Fund (Selling Fund) into RiverSource Portfolio Builder Moderate
               Aggressive Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and portfolio managers, and the same investment objective, policies and
restrictions as the Buying Fund. Prior to the reorganization, the expense
structure of the Selling Fund will be changed to be consistent with the other
funds in the RiverSource family of funds, including the Buying Fund. However, at
the time of reorganization, the expense structure of the combined fund will more
closely resemble that of the Buying Fund based upon the length of time the
expense structure has been in place and the overall expense ratio. Based on net
assets at Oct. 31, 2008, the net asset level of the Buying Fund is greater than
that of the Selling Fund. Therefore, the net asset level of the combined fund is
expected to more closely resemble that of the Buying Fund. The portfolio
composition of the combined fund is expected to more closely resemble that of
the Buying Fund than that of the Selling Fund. The investment manager therefore
believes that the totality of the factors discussed above, taken together,
suggest that the combined fund will more closely resemble the Buying Fund, and
that the Buying Fund is thus the proper accounting survivor of the proposed
reorganization.

PROPOSAL 1: Proposed reorganization of Seligman Core Fixed Income Fund, Inc.
            (Selling Fund) into RiverSource Diversified Bond Fund (Buying Fund),
            and

PROPOSAL 4: Proposed reorganization of Seligman High-Yield Fund (Selling Fund)
            into RiverSource High Yield Bond Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and portfolio managers, and the same investment objective, policies and
restrictions as the Buying Fund. Although the investment portfolio for both the
Buying Fund and the Selling Fund are currently managed by the same portfolio
management team, its tenure with the Buying Fund is longer than with the Selling
Fund. Prior to the reorganization, the expense structure of the Selling Fund
will be changed to be consistent with the other funds in the RiverSource family
of funds, including the Buying Fund. However, at the time of reorganization, the
expense structure of the combined fund will more closely resemble that of the
Buying Fund based upon the length of time the expense structure has been in
place and the overall expense ratio. Based on net assets at Oct. 31, 2008, the
net asset level of the Buying Fund is greater than that of the Selling Fund.
Therefore, the net asset level of the combined fund is expected to more closely
resemble that of the Buying Fund. The portfolio composition of the combined fund
is expected to more closely resemble that of the Buying Fund than that of the
Selling Fund. The investment manager therefore believes that the totality of the
factors discussed above, taken together, suggest that the combined fund will
more closely resemble the Buying Fund, and that the Buying Fund is thus the
proper accounting survivor of the proposed reorganization.

PROPOSAL 2: Proposed reorganization of Seligman Emerging Markets Fund (Selling
            Fund) into Threadneedle Emerging Markets Fund (Buying Fund)

PROPOSAL 3: Proposed reorganization of Seligman Global Growth Fund (Selling

PROPOSAL 6: Proposed reorganization of Seligman International Growth Fund
            (Selling Fund) into RiverSource Partners International Select Growth
            Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
manager and subadviser, and the same investment objective, policies and
restrictions as the Buying Fund. Prior to the reorganization, the



                                                                     Page 6 of 6


expense structure of the Selling Fund will be changed to be consistent with the
other funds in the RiverSource family of funds, including the Buying Fund.
However, at the time of reorganization, the expense structure of the combined
fund will more closely resemble that of the Buying Fund based upon the length of
time the expense structure has been in place, the presence of a performance
incentive adjustment to the management fee and the overall expense ratio
(excluding the impact of any performance incentive adjustment to the management
fee for the Buying Fund). Based on net assets at Oct. 31, 2008, the net asset
level of the Buying Fund is greater than that of the Selling Fund. Therefore,
the net asset level of the combined fund is expected to more closely resemble
that of the Buying Fund. The portfolio composition of the combined fund is
expected to more closely resemble that of the Buying Fund than that of the
Selling Fund. The investment manager therefore believes that the totality of the
factors discussed above, taken together, suggest that the combined fund will
more closely resemble the Buying Fund, and that the Buying Fund is thus the
proper accounting survivor of the proposed reorganization.

PROPOSAL 7: Proposed reorganization of Seligman U.S. Government Fund Securities
            Fund (Selling Fund) into RiverSource Short Duration U.S. Government
            Fund (Buying Fund)

At the time of reorganization, the combined fund will have the same investment
objective, policies and restrictions as the Buying Fund. However, the investment
manager and portfolio manager(s) for the combined fund will be the same as both
the Buying Fund and the Selling Fund. Prior to the reorganization, the expense
structure of the Selling Fund will be changed to be consistent with the other
funds in the RiverSource family of funds, including the Buying Fund. However, at
the time of reorganization, the expense structure of the combined fund will more
closely resemble that of the Buying Fund based upon the length of time the
expense structure has been in place, the presence of a performance incentive
adjustment to the management fee (for the reorganization of Seligman Income and
Growth Fund, Inc. into RiverSource Balanced Fund only) and the overall expense
ratio (excluding the impact of any performance incentive adjustment to the
management fee for RiverSource Balanced Fund). Based on net assets at Oct. 31,
2008, the net asset level of the Buying Fund is greater than that of the Selling
Fund. Therefore, the net asset level of the combined fund is expected to more
closely resemble that of the Buying Fund. The portfolio composition of the
combined fund is expected to more closely resemble that of the Buying Fund than
that of the Selling Fund. The investment manager therefore believes that the
totality of the factors discussed above, taken together, suggest that the
