Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Oregon
Municipals Fund ("Fund") for the period ended October 31, 1998. In this report,
we summarize the period's prevailing economic and market conditions and outline
our portfolio strategy. A detailed summary of the Fund's performance can be
found in the appropriate sections that follow.


Performance and Investment Strategy Update

For the six months ended October 31, 1998, the Fund's Class A shares returned
4.59% before the deduction of any sales charges. In comparison, the Fund's
Lipper Analytical Services, Inc. ("Lipper") peer group average had a total
return of 4.46% during the same period. (Lipper is an independent fund-tracking
organization.) Performance information for the Fund's other share classes can
be found beginning on page five.


Based on its net asset value ("NAV") of $11.00 as of October 31, 1998 and the
current monthly income distribution rate of $0.04 for Class A shares, the
Fund's annualized distribution rate is 4.42%. For an Oregon investor in a
combined federal and state tax bracket of 41.76%, the Fund's tax-exempt yield
of 4.42% is equivalent to a taxable yield of 7.59%. (This figure assumes an
investor is in a federal income tax bracket of 36%.)


We continue to maintain a fairly long average life in the Fund because we see
little inflation risk over the medium term. In addition, the bulk of the Fund's
assets remain in quality, high coupon issues. We believe this strategy should
boost the Fund's performance potential and help provide a steadier long-term
income when interest rates are low.


As of October 31, 1998, the Fund's average call-adjusted life was about 9 years
and 95% of the Fund's holdings were rated investment grade. In addition, 36% of
the Fund's portfolio was rated AAA, the highest quality bond rating.

Oregon Economic Highlights

Like many other parts of the country, Oregon's booming economy has started to
slow down. Oregon's economic growth has been extraordinary in recent years,
outpacing the national average gains in both employment growth and personal
income. Moreover, Oregon has been successful in further diversifying its
economy from one reliant on timber and agriculture to larger investments in
high technology and services companies. Oregon's rising standard of living has
attracted large numbers of new residents. Thanks to economic success and
prudent debt management, Oregon continues to enjoy high marks from nationally
recognized credit rating agencies.

However, many Asian nations are major trading partners with the State and
ongoing weakness in that region has already begun to affect its economy. For
example, Oregon's exports to Asian countries were down 17.9% in the first
quarter of 1998 compared to the same period last year. Overall exports in the
State were down 6.6% in the first quarter of 1998. Nevertheless, we believe
that Oregon is well positioned for future prosperity. We remain positive on its
long-term economic outlook.

Municipal Bond Market and Economic Overview

Bond market performance was shaped primarily by surging demand for U.S.
Treasury securities and a massive issuance of municipal bonds in the past six
months. During the reporting period, municipal bond prices remained relatively
flat with coupon interest providing most of the returns for municipal bonds.


Troubled financial markets abroad and a strengthening U.S. dollar further
exacerbated an already dramatic flight of capital from foreign countries into
U.S. markets. The U.S. Treasury bond, considered to be the global benchmark for
credit quality, was the chief beneficiary of these capital inflows. The large
flows of money into U.S. Treasury securities drove their prices upward and
their yields lower. On September 30, 1998, the yield of the bellwether 30-year
U.S. Treasury bond fell to 4.95%, the lowest level for long-term government
debt since 1967. Since then, long-term U.S. Treasury yields fell even further
before drifting upward in recent days.


Up until July, many bond investors had been focused on any signs of the
reappearance of inflation. However, developments in the Pacific Rim, such as
Japan's failure to shore up its ailing banking system and Russia's unexpected
devaluation of its currency, altered that view considerably. Moreover, a number
of speculators who found themselves caught in highly unusual market conditions
added to the growing uncertainty in U.S. capital markets.

<PAGE>

In response to global tumult, the Federal Reserve Board ("Fed") signaled a
shift in policy from vigilance against inflation toward concerns of global
deflation by cutting short-term interest rates 0.25% at its September 1998
meeting. The rate cut was the first action by the Fed since March 1997. Shortly
afterwards, the Fed took an extraordinary and unexpected action by cutting
short-term interest rates again by another 0.25% on October 15, 1998. This
latest action brings the federal-funds rate to 5.0% and the largely symbolic
discount rate to 4.75%.* (The federal-funds rate is the interest rate banks
charge each other for overnight loans and a closely watched indicator of the
direction of interest rates. The discount rate is the interest rate the Federal
Reserve charges its member banks for loans.)


Foreign investors, who do not benefit from the tax-exempt status of municipal
bonds, have been large buyers of U.S. Treasury securities. As a result, yields
for U.S. Treasury securities have declined further than those of municipal
bonds. Municipal bond yields are currently yielding as much as 100% of
equivalent maturity U.S. Treasury bonds. Municipal bonds are considered by many
investors to be a good value when they yield about 85% of U.S. Treasury bonds.
At their present levels, we believe that tax-exempt bonds can now provide a
competitive income stream for risk-averse investors of almost any income tax
bracket.


In contrast to the diminishing U.S. Treasury security supply, municipal bond
issuance continued at record levels. This disparity in supply and demand
between U.S. Treasury bonds and municipal bonds is a primary reason for
municipal bond underperformance relative to U.S. Treasurys.

Municipal Bond Market Outlook

As noted above, we believe that municipal bonds represent competitive values
under the current market conditions. With the stock market's recent volatility,
many investors may be looking to reallocate their existing portfolios. In our
opinion, this may be a timely opportunity for many of these investors to
consider further diversifying their portfolios with municipal bonds.


We believe that economic conditions should remain supportive for the municipal
bond market over the near term. The relatively high yield ratio between
municipal bonds and U.S. Treasury bonds should slow the rate of advance
refundings and help alleviate the oversupply of municipal bonds. Moreover, the
U.S. economy remains sound despite the widely reported economic distress of
many other countries. Although U.S. economic growth will likely slow over the
coming months, we expect the economy to expand modestly. Despite recent remarks
by Fed chairman Alan Greenspan, we expect that the Fed will be forced to
continue to gradually lower short-term interest rates and that in turn should
help correct some of the imbalances that exist in the overall bond market
today.

  November 17, 1998, after this letter was written.

+ Hypothetical illustration of $10,000 invested in Class A shares at inception
  on May 23, 1994, assuming deduction of the maximum 4.00% sales charge at the
  time of investment and reinvestment of dividends and capital gains, if any,
  at net asset value through October 31, 1998. In addition, there is an
  hypothetical illustration of $10,000 invested in Class B shares at inception
  on May 23, 1994, assuming deduction of a 4.50% CDSC, which applies if shares
  are redeemed within one year from purchase. This CDSC declines by 0.50% the
  first year after purchase and thereafter by 1.00% per year until no CDSC is
  incurred. The Lehman Brothers Municipal Bond Index is a broad based, total
  return index comprised of investment grade, fixed rate municipal bonds
  selected from issues larger than $50 million issued since January 1991. The
  index is unmanaged and is not subject to the same management and trading
  expenses as a mutual fund. The performance of the Fund's other class of
  shares may be greater or less than Class A and B shares' performance
  indicated on this chart, depending on whether greater or lesser sales
  charges and fees were incurred by shareholders investing in the other class.
   

  All figures represent past performance and are not a guarantee of future
  results. Investment returns and principal value will fluctuate, and redemption
  values may be more or less than the original cost. No adjustment has been made
  for shareholder tax liability on dividends or capital gains.

* This figure includes the effect of the cash contribution to capital from the
  investment adviser.

 Bond Ratings (unaudited)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's -- Ratings from "AA" to "BBB" may be modified by the addition
of a plus (+) or minus (-) sign to show relative standings within the major
rating categories.
<TABLE>
<S>        <C> 
AAA   --   Bonds rated "AAA" have the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
AA    --   Bonds rated "AA" have a very strong capacity to pay interest and repay principal and
           differs from the highest rated issue only in a small degree.
A     --   Bonds rated "A" have a strong capacity to pay interest and repay principal although it
           is somewhat more susceptible to the adverse effects of changes in circumstances and
           economic conditions than debt in higher rated categories.
BBB   --   Bonds rated "BBB" are regarded as having an adequate capacity to pay interest and repay
           principal. Whereas they normally exhibit adequate protection parameters, adverse
           economic conditions or changing circumstances are more likely to lead to a weakened
           capacity to pay interest and repay principal for debt in this category than in higher rated
           categories.
<CAPTION>
Moody's -- Numerical modifiers 1, 2 and 3 may be applied to each generic rating
from "Aa" to "Baa," where 1 is the highest and 3 the lowest ranking within its
generic category.

Aaa   --   Bonds rated "Aaa" are judged to be of the best quality. They carry the smallest degree
           of investment risk and are generally referred to as "gilt edge." Interest payments are
           protected by a large or by an exceptionally stable margin and principal is secure. While
           the various protective elements are likely to change, such changes as can be visualized
           are most unlikely to impair the fundamentally strong position of such issues.
Aa    --   Bonds rated "Aa" are judged to be of high quality by all standards. Together with the "Aaa"
           group they comprise what are generally known as high grade bonds. They are rated lower
           than the best bonds because margins of protection may not be as large in Aaa securities
           or fluctuation of protective elements may be of greater amplitude or there may be other
           elements present which make the long-term risks appear somewhat larger than in Aaa
           securities.
A     --   Bonds rated "A" possess many favorable investment attributes and are to be considered
           as upper medium grade obligations. Factors giving security to principal and interest are
           considered adequate but elements may be present which suggest a susceptibility to
           impairment some time in the future.
Baa   --   Bonds rated "Baa" are considered as medium grade obligations, i.e., they are neither
           highly protected nor poorly secured. Interest payments and principal security appear
           adequate for the present but certain protective elements may be lacking or may be
           characteristically unreliable over any great length of time. Such bonds lack outstanding
           investment characteristics and in fact have speculative characteristics as well.
NR    --   Indicates that the bond is not rated by Standard & Poor's or Moody's.

Short-Term Security Ratings (unaudited)

<TABLE>
<S>            <C>
SP-1     --    Standard & Poor's highest rating indicating very strong or strong capacity to pay principal
               and interest; those issues determined to possess overwhelming safety characteristics are
               denoted with a plus (+) sign.
A-1      --    Standard & Poor's highest commercial paper and variable-rate demand obligation
               (VRDO) rating indicating that the degree of safety regarding timely payment is either
               overwhelming or very strong; those issues determined to possess overwhelming safety
               characteristics are denoted with a plus (+) sign.
VMIG 1   --    Moody's highest rating for issues having a demand feature--VRDO.
P-1      --    Moody's highest rating for commercial paper and for VRDO prior to the advent of the
               VMIG 1 rating.

1. Significant Accounting Policies

Smith Barney Oregon Municipals Fund ("Fund"), a Massachusetts business trust,
is registered under the Investment Company Act of 1940, as amended, as a non-
diversified, open-end management investment company.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities are
valued at the mean between the quoted bid and ask prices provided by an
independent pricing service; (c) securities maturing within 60 days are valued
at cost plus accreted discount or minus amortized premium, which approximates
value; (d) gains or losses on the sale of securities are calculated by using
the specific identification method; (e) interest income, adjusted for
amortization of premium and accretion of original issue discount, is recorded
on an accrual basis; market discount is recognized upon the disposition of the
security; (f) direct expenses are charged to the Fund and each class;
investment advisory, administration fees and general fund expenses are
allocated on the basis of relative net assets by class; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the
Fund intends to comply with the applicable provisions of the Internal Revenue
Code of 1986, as amended, pertaining to regulated investment companies and to
make distributions of taxable income sufficient to relieve it from
substantially all Federal income and excise taxes; (i) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles; and
(j) estimates and assumptions are required to be made regarding assets,
liabilities and changes in net assets resulting from operations when financial
statements are prepared. Changes in the economic environment, financial markets
and any other parameters used in determining these estimates could cause actual
results to differ.

In addition, organization costs have been deferred and are being amortized on a
straight-line method over a five-year period, beginning with the commencement
of the Fund's operations in May 1994.

2. Fund Concentration
Since the Fund invests primarily in obligations of issuers within Oregon, it is
subject to possible concentration risks associated with economic, political or
legal developments or industrial or regional matters specifically affecting
Oregon.

3. Exempt-Interest Dividends and Other Distributions
The Fund intends to satisfy conditions that will enable interest from municipal
securities, which is exempt from regular Federal income tax and from designated
state income taxes, to retain such tax-exempt status when distributed to the
shareholders of the Fund.

<PAGE>

Notes to Financial Statements (unaudited) (continued)

Capital gains distributions, if any, are taxable to shareholders, and are
declared and paid at least annually. Additional taxable distributions may be
made if necessary to avoid a Federal excise tax.

4. Investment Advisory Agreement, Administration Agreement and Affiliated
   Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment adviser to the Fund. The Fund pays MMC an
investment advisory fee calculated at an annual rate of 0.30% of the Fund's
average daily net assets. This fee is calculated daily and paid monthly. MMC
waived $9,247 of the investment advisory fees for the Fund for the six months
ended October 31, 1998.

MMC also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets up to
$500 million and 0.18% of the average daily net assets in excess of $500
million. This fee is calculated daily and paid monthly. MMC waived $6,164 of
its administration fees for the six months ended October 31, 1998.


On October 8, 1998, CFBDS, Inc. became the Fund's distributor. Prior to that
date Salomon Smith Barney Inc. ("SSB"), was the Fund's distributor. SSB (as
well as certain other broker-dealers) continues to sell Fund shares to the
public as members of the selling group.


On June 12, 1998, the Portfolio's existing Class C shares were renamed Class L
shares. Effective June 15, 1998, Class L shares are being sold at net asset
value plus a maximum initial sales charge of 1.00%. Class L shares also have a
1.00% contingent deferred sales charge ("CDSC"), which applies if redemption
occurs within the first year of purchase.


There is also a CDSC of 4.50% on Class B shares, which applies if redemption
occurs within one year from purchase. This CDSC declines by 0.50% the first
year after purchase and thereafter by 1.00% per year until no CDSC is incurred.
 


For the six months ended October 31, 1998, SSB received sales charges of
$22,000 and $3,000 on sales of the Fund's Class A and Class L shares,
respectively. In addition, CDSCs paid to SSB for Class B shares were
approximately $20,000.

At October 31, 1998, the Fund had an unlimited number of shares of beneficial
interest authorized with par value of $0.001 per share. The Fund has the
ability to issue multiple classes of shares. Each share of a class represents
an identical interest and has the same rights, except that each class bears
certain direct expenses, including those specifically related to the
distribution of its shares. Effective June 12, 1998, the Fund adopted the
renaming of existing Class C shares as Class L shares.
