                           FORWARD-LOOKING STATEMENTS
 
     This prospectus supplement, the prospectus, and their incorporated
documents discuss both historical information and forward-looking statements.
Most of the statements in the section of this prospectus supplement labeled "The
Company -- Strategy" are forward-looking statements. Words like "estimates,"
"expects," "plans," "anticipates," "intends," "believes," "projected,"
"forecast," and others also identify forward-looking statements. These
forward-looking statements involve uncertainties and risks. Although we believe
they are based on reasonable assumptions, we cannot assure that every stated
objective will be reached.
 
     We make forward-looking statements in reliance on the safe harbor
protections provided under the Private Securities Litigation Reform Act of 1995.
Please refer to our latest Annual Report on Form 10-K or our most recent
Quarterly Report on Form 10-Q for a discussion of important factors that could
cause our actual results to differ materially from those discussed in our
forward-looking statements.

     - New Business expenditures are for property, plant, and equipment that
       allow us to add new customers and increase the amount of gas that we
       deliver. We expect that new business will represent nearly 58 percent of
       our capital expenditures over the next five years.
 
     - Replacements expenditures help to keep our gas distribution system safe
       and reliable. We replace parts of the system as they become worn or
       obsolete, or if public authorities request that we move our facilities.
       We expect to spend just over 25 percent of our capital expenditures on
       replacements through 2003.
 
     - The remaining category, Other, is for general property and equipment such
       as buildings and related fixtures, vehicles, and computers.
 
                                USE OF PROCEEDS
 
     We will use the net proceeds realized from selling the common stock for
general corporate purposes, including capital expenditures and working capital
requirements.

                                  THE COMPANY
 
OVERVIEW
 
     The company and its distribution subsidiary are public utilities that
deliver natural gas through a nearly 22,000-mile distribution system to more
than 819,000 customers. Our service territory covers more than 6,600 square
miles, has a population estimated at 4.6 million people, and includes the City
of Washington, DC, the surrounding suburbs in Maryland and Virginia, and a
portion of the Shenandoah Valley in Virginia and West Virginia.
 
     We have been engaged in the gas distribution business for 150 years, having
been originally incorporated by an Act of Congress in 1848. We became a domestic
corporation of the Commonwealth of Virginia in 1953 and a corporation of the
District of Columbia in 1957.
 
     Average annual meter growth on our natural gas distribution system has
exceeded three percent during the last five years. Firm customers provide a
stable financial base, accounting for 72.3 percent of our therm deliveries in
fiscal year 1998. Interruptible customers, who must be able to switch to another
fuel during times of peak demand, tend to consume more gas, at lower margins,
than firm customers.

STRATEGY
 
     Deregulation and increased competition have led to significant changes in
the energy industry. As a natural gas utility, we have traditionally provided a
"bundled" service to our customers, including two primary functions: (1) the
merchant function, and (2) the core utility, or delivery, function. As the
industry has changed, we have changed our views of these functions. The
following discussion describes the merchant and core utility functions as they
exist today, and how we expect them to change over time. In addition, we discuss
our current plans for unregulated activities.
 
     The Merchant Function.  Historically, we have bought natural gas for our
customers from producers, and have had it delivered to the entrance point of our
distribution system by interstate pipeline companies. Subject to regulatory
prudence reviews, we have passed the costs paid to the producers and the
interstate pipelines directly to our customers, generally without our having any
opportunity for profit or any risk of loss.
 
     The merchant function is the industry segment currently experiencing the
greatest change. Customers in many states are being offered the opportunity to
purchase their natural gas from unregulated marketers as well as from their
regulated local distribution company. These unregulated marketers compete for
these sales and have the opportunity to make a profit or incur a loss from them.
One of our subsidiaries is an unregulated marketer.
 
     Ultimately, we expect our regulated local distribution company to play a
much smaller role in the merchant function. The distribution company may
ultimately exit the merchant function as more customers buy natural gas from
unregulated marketers. During this transition period, we will continue to have
certain obligations under long-term contracts to purchase both natural gas from
producers and transportation capacity from interstate pipeline companies.
Accordingly, our strategy will focus on recovering contractual costs and
maximizing the value of contractual assets. We currently plan to avoid some
activities that are often considered part of the merchant function, such as
commodity trading, exploring for and producing natural gas, operating interstate
natural gas pipelines, or expanding storage facilities beyond current capacity.

     The Core Utility or Delivery Function.  Through the construction of our
distribution system, we have committed over 90% of our assets to the delivery of
natural gas to our customers. The core utility function currently includes the
infrastructure needed to provide such customer services as reading meters,
preparing bills, and answering telephone inquiries. Historically, our local
regulatory commissions have allowed us to earn a fair rate of return on the
capital invested in our distribution system and to recover expenses such as
customer service and maintenance costs, taxes, and depreciation.
 
     The high cost of constructing a duplicate distribution system is a strong
barrier to potential competitors in the delivery function. Thus, we do not
expect direct competition from another natural gas distributor. We expect that
the local regulatory commissions will continue to function as surrogates for
competition, determining the prices we charge our customers and the terms and
conditions of service for the delivery function. Because of continuing
regulation, we do not expect the risk profile of the delivery function to
change, and we do not expect the profitability of the delivery function to
decline as a result of customers purchasing natural gas from unregulated
marketers. We plan to continue to construct, operate and maintain our natural
gas distribution system, increase the efficiency of our operations, add
customers profitably, and compete against other fuels such as electricity and
oil.
 
     Although we currently provide customer services as part of our core utility
function, these services can potentially be offered economically by competitors.
We may or may not continue our role as the provider of customer services,
depending on our competitive position, customer demand, and regulatory policy
preferences.
 
     Unregulated Activities.  The unregulated activities of the company and its
subsidiaries include the following:
 
        1. selling natural gas in competition with unregulated marketers and
     unregulated marketing subsidiaries of other utility companies;
 
        2. providing commercial energy services by designing and renovating
     mechanical heating, ventilating and air conditioning systems; and
 
        3. financing gas appliances and certain other equipment for residential
     and small commercial customers.
 
     At the present time, our unregulated activities are not significant to the
company's results of operations. However, our gas marketing activities involve
risks not historically experienced in our natural gas distribution business
because they require us to manage any difference between the price and volume of
natural gas we commit to our customers and the actual cost and volumes we must
purchase. Currently, we manage this risk by closely matching purchases of
natural gas from suppliers with commitments to sell natural gas to customers at
offered prices.
 
     We intend to continue competing in the energy-related markets listed above,
and potentially to enter into others. Accordingly, we are studying the
possibility of changing our corporate structure to clarify the separation of
regulated from unregulated operations, if appropriate for business and
regulatory reasons. One structural option we are considering is the formation of
a parent holding company like that of many other utilities.
 
              COMMON STOCK PRICE RANGE, DIVIDENDS, AND SHARE DATA
 
     As of 1998, we have paid dividends on our common stock for 147 consecutive
years, one of the longest dividend records of companies listed on the New York

22 years. We declare dividends on a quarterly basis, and formally review
dividend policy annually. Future earnings growth and the strength of our
financial condition may affect future dividend payments. Please refer to

     The underwriters are obligated to purchase all shares of common stock
offered hereby if any shares are purchased. We have granted to the underwriters
an option, exercisable within 30 days after the date of this prospectus
supplement, to purchase up to 300,000 additional shares of common stock solely
for the purpose of covering over-allotments, if any, at the public offering
price less the underwriting discounts and commissions set forth on the cover
page hereof. If the underwriters exercise this option, each underwriter will be
committed, subject to certain conditions, to purchase an additional number of
shares of common stock proportionate to such underwriter's initial commitment.
 
     The shares of common stock are offered subject to prior sale, when, as and
if issued by the company and accepted by the underwriters, to the public at the
public offering price set forth on the cover page hereof and to certain dealers
at such price less a concession not exceeding $0.50 per share. Underwriters and
dealers may reallow to certain other dealers a discount not exceeding $0.10 per
share. After the public offering, the public offering price and concessions and
discounts to dealers may be changed by the underwriters.
 
     The underwriting agreement provides that we will indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act of
1933, as amended.
 
     In connection with this offering, the underwriters may purchase and sell
shares of our common stock in the open market. These transactions may include
over-allotment and stabilizing transactions and purchases to cover syndicate
short positions created in connection with this offering. Stabilizing
transactions consist of certain bids or purchases for the purpose of preventing
or retarding a decline in the market price of the common stock; and syndicate
short positions involve the sale by the underwriters of a greater number of
shares of common stock than they are required to purchase from us in this
offering. The underwriters also may impose a penalty bid, whereby selling
concessions allowed to syndicate members or other broker-dealers in respect of
the shares of common stock sold in this offering for their account, may be
reclaimed by the syndicate if such shares of common stock are repurchased by the
syndicate in stabilizing or covering transactions. These activities may
stabilize, maintain or otherwise affect the market price of the common stock,
which may be higher than the price that might otherwise prevail in the open
market; and these activities, if commenced, may be discontinued at any time
without notice. These transactions may be effected on the New York Stock
Exchange or otherwise.
 
     The underwriters have in the past and may in the future engage in
transactions with, or perform services for, us in the ordinary course of their
business.

     The Company and its distribution subsidiary are public utilities that
deliver and sell natural gas through a 21,000-mile distribution system to more
than 818,000 customers. The franchise area covers over 6,600 square miles and
has a population estimated at 4.6 million people. This area includes the City of
Washington, D.C. and the surrounding suburbs in Maryland and Virginia, and a
portion of the Shenandoah Valley in Virginia and West Virginia.
 
     The Company has been engaged in the gas distribution business for 150
years, having been originally incorporated by an Act of Congress in 1848. It
became a domestic corporation of the Commonwealth of Virginia in 1953 and a
corporation of the District of Columbia in 1957.
 
     Meter growth on the Company's natural gas distribution system has averaged
over 3 percent annually during the last five years. Residential and firm
commercial customers provide a stable financial base, accounting for 72.4
percent of the Company's therm deliveries in fiscal year 1997.
 
     Non-utility activities of the Company and its subsidiaries include: (1) the
sale of natural gas in competition with third-party suppliers such as gas
marketers and non-regulated subsidiaries of other utility companies; (2)
providing commercial energy services by designing and renovating mechanical
heating, air conditioning and ventilation systems; and (3) the financing of gas
appliances and certain other equipment for residential and small commercial
customers.
 
     The principal executive offices of the Company are located at 1100 H

shares of such stock, the holders of the Preferred Stock (whether voting or
non-voting) have the right, as a class, until all dividends then in default have
been paid, to elect the largest number of directors that does not exceed 25% of
the Board of Directors, but in no event less than two directors; and the holders
of Common Stock will be entitled to elect the remaining directors.
 
     Upon liquidation, the holders of Common Stock shall be entitled to share
ratably in the distribution of the remaining assets available for distribution
after satisfaction of the preferential liquidation requirements of, and
accumulated unpaid dividends on, the Preferred Stock. The Common Stock and all
series of Preferred Stock have no preemptive rights.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Company's Common Stock is The Bank
of New York. The Bank of New York extends credit to the Company, along with
other banks, under revolving credit agreements. From time to time the Company
has entered into contracts with The Bank of New York for the sale, on a recourse
basis, of certain non-utility accounts receivable. The Bank of New York also
serves as transfer agent and registrar for the Company's Preferred Stock.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Common Stock in any of three ways: (1) through
underwriters or dealers; (2) directly to a limited number of purchasers or to a
single purchaser; or (3) through agents. The distribution of the Common Stock
may be effected from time-to-time in one or more transactions at a fixed price,
at a price which may be changed, at market prices prevailing at the time of
sale, at prices related to such prevailing market prices, or at negotiated
prices. Each Prospectus Supplement will set forth the terms of the offering of
the Common Stock offered thereby, including the name or names of any
underwriters or agents, the purchase price of such Common Stock and the proceeds
to the Company from such sale, any discounts and other items constituting
underwriters' and agents' compensation, and any discounts or concessions allowed
or reallowed or paid to dealers. Any initial public offering price and any
discounts or concessions allowed or reallowed or paid to dealers may be changed
from time to time.
 
     If underwriters are used in the sale, the Common Stock will be acquired by
the underwriters for their own account and may be sold from time to time in one
or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of the sale. The
Common Stock may be offered to the public either through underwriting syndicates
represented by one or more managing underwriters as may be designated by the
Company, or directly by one or more of such firms. The underwriter or
underwriters with respect to a particular underwritten offering of Common Stock
will be named in the Prospectus Supplement relating to such offering and, if an
underwriting syndicate is used, the managing underwriter or underwriters will be
set forth on the cover page of such Prospectus Supplement. Unless otherwise set
forth in a Prospectus Supplement, the obligations of the underwriters to
purchase the Common Stock offered thereby will be subject to certain conditions
precedent, and the underwriters will be obligated to purchase all such shares of
Common Stock if any are purchased.
 
     The Company may grant to underwriters options to purchase additional Common
Stock to cover over-allotments, if any, at the initial public offering price
(with additional underwriting commissions or discounts), as may be set forth in
the applicable Prospectus Supplement. If the Company grants any over-allotment
option, the terms of such option will be set forth in the applicable Prospectus
Supplement.
 
     The Common Stock may be sold through agents designated by the Company from
time to time. Each Prospectus Supplement will set forth the name of any agent
involved in the offer or sale of the Common Stock in respect of which such
Prospectus Supplement is delivered as well as any commissions payable by the
Company to such agent. Unless otherwise indicated in such Prospectus Supplement,
any such agent will be acting on a best efforts basis for the period of its
appointment. Any such agent may be deemed to be an underwriter, as that term is
defined in the Securities Act of 1933, as amended ("Securities Act"), of the
Common Stock so offered and sold.

     If a dealer is utilized in the sale of Common Stock in respect of which
this Prospectus is delivered, the Company will sell such Common Stock to the
dealer as principal. The dealer may then resell such Common Stock to the public
at varying prices to be determined by such dealer at the time of resale. Any
such dealer may be deemed to be an underwriter, as such item is defined in the
Securities Act, of the Securities so offered and sold. The name of the dealer
and the terms of the transaction will be set forth in the applicable Prospectus
Supplement.
 
     Offers to purchase Common Stock may be solicited directly by the Company,
and the sale thereof may be made directly by the Company to institutional
investors or others who may be deemed underwriters within the meaning of the
Securities Act with respect to any resale thereof. The terms of any such sales
will be described in the applicable Prospectus Supplement.
 
     If so indicated in a Prospectus Supplement, the Company will authorize
agents, underwriters or dealers to solicit offers by certain specified
institutions to purchase the Common Stock offered thereby from the Company at
the public offering price set forth in such Prospectus Supplement pursuant to
delayed delivery contracts providing for payment and delivery on a specified
date in the future. Such contracts will be subject to those conditions set forth
in such Prospectus Supplement, which will set forth the commission payable for
solicitation of such contracts.
 
     Agents and underwriters may be entitled under agreements entered into with
the Company to indemnification by the Company against certain civil liabilities,
including liabilities under the Securities Act. Agents, underwriters, and
dealers may be customers of, engage in transactions with, or perform services
for, the Company in the ordinary course of business.
