                                  SCHEDULE XIV

                         NOTES TO FINANCIAL STATEMENTS

- --------------------------------------------------------------------------------
INSTRUCTIONS:    The space below is provided for important notes regarding the 
                 financial statements or any account thereof.  Furnish 
                 particulars as to any significant contingent assets or
                 liabilities existing at the end of the year.  Notes relating 
                 to financial statements shown elsewhere in this report may be 
                 indicated here by reference.
- --------------------------------------------------------------------------------
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    a. Property, Plant and Equipment and Related Depreciation

           Property, Plant and Equipment is stated at historical cost.
       Depreciation is provided on a composite straight-line basis using the
       average of depreciable property at the beginning and end of each year.

    b. Income Taxes

           The Corporation provides deferred taxes with respect to timing
       differences in the recognition of revenues and expenses for tax and
       accounting purposes.  The major difference results from using
       accelerated depreciation for tax purposes.  The Corporation is included
       in the Consolidated Federal Income Tax Return filed for The Columbia Gas
       System, Inc.

    c. Pension Costs

           The Corporation participates in the Retirement Income Plan of The
       Columbia Gas System, Inc.  This is a trusteed noncontributory Retirement
       Income Plan which, with certain minor exceptions, covers all regular
       employees.  The Service Corporation's portion amounted to $2,194,252 in
       1993 and $2,015,343 in 1992, including the amortization of unfunded
       prior service costs.

    d. Leases

           Payments made by the Corporation in connection with operating leases
        are charged to expense as incurred.

    e. Account Numbers

           The Corporation uses certain FERC accounts which do not match
       existing SEC accounts; therefore, the year-end balances of the following
       FERC accounts were reclassified to a corresponding SEC account.

    f.  Post-Retirement Benefits Other Than Pensions

             During 1991, the System adopted SFAS No. 106, Employer's
        Accounting for Post-Retirement Benefits Other Than Pensions,
        retroactive to January 1, 1991.  The Corporation has elected to record
        and defer the full amount of its estimated accumulated post-retirement
        obligations other than pensions.  These obligations total $12,990,009
        as of December 31, 1993, and represent the actuarial present value of
        the post-retirement benefits to be paid to current employees and
        retirees based on services rendered.

    g.  System Money Pool

             During 1993, the Corporation served as the administrator of the
        System Money Pool, which allows for affiliate companies to loan excess
        cash to other affiliate companies.  Listed below are the outstanding
        balances at December 31, 1992 and 1993 respectively.
