To the Shareholders
During Seligman Pennsylvania Municipal Fund's six-month reporting period ended
March 31, 1999, the US economy remained strong. In fact, the economy grew faster
than almost anyone had predicted. The Pennsylvania economy participated in this
growth, and the financial condition of the state and its municipalities
benefited from the ongoing expansion.
At the Fund's fiscal year-end in September 1998, the consensus was that the US
economy would slow, possibly to recessionary levels, in the face of worldwide
financial disorder brought on by the Asian economic crisis. However, US consumer
strength was widely underestimated, and consumer confidence and the strong
consumer demand that accompanied it remained a powerful economic force. Not only
did the economy continue to surprise on the upside, it did so without signs of
rising inflation, a common side effect of prolonged and robust growth.
Despite evidence that inflation remained under control, the unexpected
acceleration in economic activity earlier this year caused bond market
participants to worry that inflation posed a possible threat. This concern
pushed Treasury yields significantly higher. During these six months, Treasury
bond yields fluctuated within a wide range of 98 basis points. In contrast, the
Pennsylvania municipal market remained relatively stable, with yields
fluctuating within a much narrower range of 16 basis points.
At the Fund's fiscal year-end in September 1998, the yield spread between
municipal bonds and Treasuries was unprecedentedly narrow. Recently, however, a
slowdown in the supply of new municipal bond issues and rising Treasury yields
caused the yield spread between municipal bonds and Treasury bonds to widen to a
more historically normal range. We believe that this trend will continue and, as
it does, the performance of the municipal market should improve relative to the
Treasury market.
The ongoing economic expansion in the US continued to benefit the municipal bond
market. Municipal bond issuers have been able to improve their financial
situations and, for the fourth year in a row, there were more credit-rating
upgrades than downgrades. We expect that this positive trend will continue.
The Fund's manager, J. & W. Seligman & Co. Incorporated, continues to work to
ensure that all of its operations are prepared for the challenges posed by the
Year 2000 (Y2K) computer issue. We are confident that there will be no
disruption in the investment and shareholder services provided by the Fund as a
result of Y2K. In addition, your portfolio management team considers the
potential ramifications of Y2K when making decisions on which securities should
be held by the Fund.
We appreciate your confidence in Seligman Pennsylvania Municipal Fund and look
forward to serving your investment needs for many years to come. A discussion
with your Portfolio Manager and the Fund's portfolio of investments follow this
letter.

Interview With Your Portfolio Manager,
Thomas G. Moles
Q: What economic and market factors influenced Seligman Pennsylvania
Municipal Fund in the last six months?
A: During the past six months, the outlook for the US and global economies has
improved dramatically. At fiscal year-end in September 1998, economies
around the world were struggling with financial crises that threatened to
drag the US into recession. In response, the Federal Reserve Board took
immediate defensive action by lowering the federal funds rate three times
last fall.
However, the outlook for the US economy brightened as economies around the
world began to show signs of recovery and as strong US consumer demand
continued to drive economic growth.
While ending on a positive note, the last six months were nonetheless
volatile for equity markets, and thus for the US Treasury market, as
investors rushed to buy Treasury bonds during periods of market uncertainty.
This "flight to quality" was the primary cause of the sharp swings in
Treasury yields that were experienced during the period. The yield on the
30-year US Treasury bond fluctuated by more than 98 basis points during this
time.
In contrast to the volatility of the Treasury market, the municipal market
remained relatively stable throughout the period. Long-term municipal
interest rates fluctuated within a much narrower trading range of
approximately 32 basis points.
The historically low interest-rate environment led to a surge in municipal
new issue volume during 1998. The increase in municipal supply caused the
yield spread between municipal bonds and Treasury bonds to narrow, making
municipals particularly attractive. For a brief period in October, long-term
municipal yields actually exceeded long-term Treasury yields, an unusual
occurrence given the tax advantages of municipal ownership.

Interview With Your Portfolio Manager,
Thomas G. Moles
This situation has now begun to reverse itself. Year-to-date, new issue
volume has slowed from its robust pace, causing the yield spread between
municipal bonds and Treasury bonds to widen to a historically normal range.
The continued strength of the US economy, which is now in its ninth year of
economic expansion, has allowed the financial condition of the nation's
states, cities, and municipalities to steadily improve. For the fourth year
in a row, credit-rating upgrades exceeded downgrades. We expect that this
positive trend will continue with the possible exception of healthcare
bonds, whose issuers have been experiencing increased financial and
operating pressures.
Q: What was your investment strategy?
A: The relative lack of volatility in the municipal market limited our
opportunities to enhance total return through trading activity. Therefore,
we focused on improving the relative value of Seligman Pennsylvania
Municipal Fund's portfolio. Through in-depth credit analysis and market
research, we have been able to identify municipal credits that we believe
have been undervalued by the market, and we have used this information in
our security selection process.
During the period, our investment strategy was consistent with our
positive outlook for the economy and long-term interest rates. We reduced
portfolio holdings with short durations, replacing them with longer-term
bonds because they offer the greatest opportunity for price appreciation
during periods of declining interest rates. (Conversely, during periods of
rising interest rates, long-term bonds will depreciate more than
shorter-term bonds.) Long-term bonds have also provided the highest yields
historically. During the past six months, long-term municipal yields rose
slightly, resulting in a decline in Seligman Pennsylvania Municipal Fund's
net asset value.
We have concentrated new purchases in triple "A" rated insured bonds because
of the prevailing narrow yield spread between high-quality and lower-quality
bonds. At this time, lower-quality bonds do not offer enough additional
yield to compensate for the increased credit risk. For the six-month period,
high-quality insured bonds outperformed lower-quality bonds.
Q: What is your outlook?
A: Recent economic reports have suggested that the economy may be
strengthening further, raising concerns about an acceleration in the rate
of inflation. In response, long-term municipal yields have increased
modestly. However, we believe that any increase in long-term yields will
be temporary and our outlook for interest rates remains positive. We will
continually monitor market conditions and will adjust our investment
strategy accordingly.
There are currently a number of factors that bode well for the municipal
market going forward. First, new issue supply has slowed, widening the yield
spread between municipals and Treasuries to a historically normal range. If
this trend continues, and we believe that it will, the performance of the
municipal market should improve relative to the Treasury market. In
addition, the municipal bond market has been the beneficiary of a healthy
economy and a stable rate of inflation, and we anticipate that these
favorable market conditions will continue for the balance of the year.

NOTES TO FINANCIAL STATEMENTS
1. Multiple Classes of Shares -- Seligman Pennsylvania Municipal Fund (the
"Fund") offers two classes of shares. Class A shares are sold with an initial
sales charge of up to 4.75% and a continuing service fee of up to 0.25% on an
annual basis. Class A shares purchased in an amount of $1,000,000 or more are
sold without an initial sales charge but are subject to a contingent deferred
sales charge ("CDSC") of 1% on redemptions within 18 months of purchase. Class D
shares are sold without an initial sales charge but are subject to a
distribution fee of up to 0.75% and a service fee of up to 0.25% on an annual
basis, and a CDSC of 1% imposed on redemptions made within one year of purchase.
The two classes of shares represent interests in the same portfolio of
investments, have the same rights, and are generally identical in all respects
except that each class bears its separate distribution and certain other class
expenses, and has exclusive voting rights with respect to any matter on which a
separate vote of any class is required.
2. Significant Accounting Policies -- The financial statements have been
prepared in conformity with generally accepted accounting principles which
require management to make certain estimates and assumptions at the date of the
financial statements. The following summarizes the significant accounting
policies of the Fund:
a. Security Valuation -- All municipal securities and other short-term
holdings maturing in more than 60 days are valued based upon quotations
provided by an independent pricing service or, in their absence, at fair
value determined in accordance with procedures adopted by the Trustees.
Short-term holdings maturing in 60 days or less are generally valued at
amortized cost.
b. Federal Taxes -- There is no provision for federal income tax. The Fund has
elected to be taxed as a regulated investment company and intends to
distribute substantially all taxable net income and net gain realized.
c. Security Transactions and Related Investment Income -- Investment
transactions are recorded on trade dates. Identified cost of investments
sold is used for both financial statement and federal income tax purposes.
Interest income is recorded on the accrual basis. The Fund amortizes
original issue discounts and premiums paid on purchases of portfolio
securities. Discounts other than original issue discounts are not amortized.
d. Multiple Class Allocations -- All income, expenses (other than
class-specific expenses), and realized and unrealized gains or losses are
allocated daily to each class of shares based upon the relative value of the
shares of each class. Class-specific expenses, which include distribution
and service fees and any other items that are specifically attributable to a
particular class, are charged directly to such class. For the six months
ended March 31, 1999, distribution and service fees were the only
class-specific expenses.
e. Distributions to Shareholders -- Dividends are declared daily and paid
monthly. Other distributions paid by the Fund are recorded on the
ex-dividend date. The treatment for financial statement purposes of
distributions made to shareholders during the year from net investment
income or net realized gains may differ from their ultimate treatment for
federal income tax purposes. These differences are caused primarily by
differences in the timing of the recog nition of certain components of
income, expense, or realized capital gain for federal income tax purposes.
Where such differ ences are permanent in nature, they are reclassified in
the components of net assets based on their ultimate characterization for
federal income tax purposes. Any such reclassifications will have no effect
on net assets, results of operations or net asset value per share of the
Fund.

NOTES TO FINANCIAL STATEMENTS
3. Purchases and Sales of Securities -- Purchases and sales of portfolio
securities, excluding short-term investments, for the six months ended March 31,
1999, amounted to $2,183,788 and $926,234, respectively.
At March 31, 1999, the cost of investments for federal income tax purposes
was substantially the same as the cost for financial reporting purposes, and the
tax basis gross unrealized appreciation and depreciation of investments amounted
to $1,841,495 and $7,025, respectively.
4. Management Fee, Distribution Services, and Other Transactions -- J. & W.
Seligman & Co. Incorporated (the "Manager") manages the affairs of the Fund and
provides the necessary personnel and facilities. Compensation of all officers
of the Fund, all trustees of the Fund who are employees or consultants of the
Manager, and all personnel of the Fund and the Manager is paid by the Manager.
The Manager's fee, calculated daily and payable monthly, is equal to 0.50% per
annum of the Fund's average daily net assets.
Seligman Advisors, Inc. (the "Distributor"), agent for the distribution of
the Fund's shares and an affiliate of the Manager, received concessions of
$1,209 for sales of Class A shares, after commissions of $9,236 paid to

shares for which the organizations are responsible; and fees for providing other
distribution assistance of up to 0.75% on an annual basis of such average daily
net assets. Such fees are paid monthly by the Fund to the Distributor pursuant
to the Plan. For the six months ended March 31, 1999, fees incurred under the
Plan amounted to $4,029, or 1% per annum of the average daily net assets of
Class D shares.

Report of Independent Auditors
The Trustees and Shareholders,
Seligman Pennsylvania Municipal Fund:
We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Seligman Pennsylvania Municipal Fund as of
March 31, 1999, the related statements of operations for the six months then
ended and of changes in net assets for the six months then ended and for the
year ended September 30, 1998, and the financial highlights for each of the
periods presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
March 31, 1999 by correspondence with the Fund's custodian and brokers; where
replies were not received from brokers, we performed other auditing procedures.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
In our opinion, such financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Seligman Pennsylvania Municipal Fund as of March 31, 1999, the results of its
operations, the changes in its net assets, and the financial highlights for the
respective stated periods, in conformity with generally accepted accounting
principles.

GLOSSARY OF FINANCIAL TERMS
Capital Gain Distribution -- A payment to mutual fund shareholders of profits
realized on the sale of securities in the fund's portfolio.
Capital Appreciation/Depreciation -- An increase or decrease in the market
value of a mutual fund's portfolio securities, which is reflected in the net
asset value of the fund's shares. Capital appreciation/depreciation of an
individual security is in relation to the original purchase price.
Compounding -- The change in the value of an investment as shareholders receive
earnings on their investment's earnings. For example, if $1,000 is invested at
a fixed rate of 7% a year, the initial investment is worth $1,070 after one
year. If the return is compounded, second year earnings will not be based on
the original $1,000, but on the $1,070, which includes the first year's
earnings.
Contingent Deferred Sales Charge (CDSC) -- Depending on the class of shares
owned, a fee charged by a mutual fund when shares are sold back to the fund
(the CDSC expires after a fixed time period).
Dividend -- A payment by a mutual fund, usually derived from the fund's net
investment income (dividends and interest less expenses).
Dividend Yield -- A measurement of a fund's dividend as a percentage of the
maximum offering price or net asset value.
Expense Ratio -- The cost of doing business for a mutual fund, expressed as a
percent of the fund's net assets.
Investment Objective -- The shared investment goal of a fund and its
shareholders.
Management Fee -- The amount paid by a mutual fund to its investment
advisor(s).
Multiple Classes of Shares -- Although an individual mutual fund invests in
only one portfolio of securities, it may offer investors several purchase
options which are "classes" of shares. Multiple classes permit shareholders to
choose the fee structure that best meets their needs and goals. Generally, each
class will differ in terms of how and when sales charges and certain fees are
assessed.
National Association of Securities Dealers, Inc. (NASD) -- A self-regulatory
body with authority over firms that distribute mutual funds.
Net Asset Value (NAV) Per Share -- The market worth of one fund share, obtained
by adding a mutual fund's total assets (securities, cash, and any accrued
earnings), subtracting liabilities, and dividing the resulting net assets by the
number of shares outstanding.
Offering Price -- The price at which a mutual fund's share can be purchased.
The offering price is the current net asset value per share plus any sales
charge.
Portfolio Turnover -- A measure of the trading activity in a mutual fund's
investment portfolio that reflects how often securities are bought and sold.
Prospectus -- The legal document describing a mutual fund to all prospective
shareholders. It contains information required by the Securities and Exchange
Commission, such as the fund's investment objective and policies, services,
investment restrictions, how shares are bought and sold, fund fees and other
charges, and the fund's financial highlights.
SEC Yield -- SEC Yield refers to the net income earned by a fund during a
recent 30-day period. This income is annualized and then divided by the maximum
offering price per share on the last day of the 30-day period. The SEC Yield
formula reflects semiannual compounding.
Securities and Exchange Commission -- The primary US federal agency that
regulates the registration and distribution of mutual fund shares.
Statement of Additional Information -- A document that contains more detailed
information about an investment company and that supplements the prospectus. It
is available at no charge upon request.
Total Return -- A measure of fund performance encompassing all elements of
return. Reflects the change in share price over a given period and assumes all
distributions are taken in additional fund shares. The Average Annual Total
Return represents the average annual compounded rate of return for the periods
presented.
Yield on Securities -- For bonds, the current yield is the coupon rate of
interest, divided by the purchase price. For stocks, the yield is measured by
dividing dividends paid by the maximum offering price of the stock.
