                                  PART I

Item 1.  Financial Statements

The unaudited Financial Statements of Atlas-Energy for the Nineties-Public
#6 Ltd. (the "Partnership") for the period January 1, 1999 to September 30,
1999

Item 2.  Description of Business

The Partnership has placed into production 44.45 net wells to
the Clinton/Medina formation in Mercer and Lawrence Counties, Pennsylvania.
As of September 30, 1999, all 44.45 net wells are in production. The first
quarterly distribution was on June 8, 1998 for natural gas production
during January, February and March, 1998.

Natural gas sales revenue for the three months was $367,384 which includes
landowner royalties.  Expenses for this period include $75.00 per month
per well for administrative costs and $275.00 per month per well for pumpers
fees.

For the next twelve months management believes that the Partnership has
adequate capital.  No other wells will be drilled and, therefore, no
additional funds will be required.

Although management does not anticipate that the Partnership will have to
do so, any additional funds which may be required will be obtained from
production revenues from Partnership wells or from borrowings by the
Partnership from Atlas or its affiliates, although Atlas is not
contractually committed to make such a loan.  No borrowings will be
obtained from third parties.

             NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

          ATLAS-ENERGY FOR THE NINETIES--PUBLIC #6 LTD.
                   A PENNSYLVANIA LIMITED PARTNERSHIP

                            Sept 30, 1999

1.      INTERIM FINANCIAL STATEMENTS

The financial statements as of September 30, 1999 and for the nine months then
ended have been prepared by the management of the Partnership without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission.  Certain information and footnote disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been omitted pursuant to such rules and
regulations, although the Partnership believes that the disclosures are
adequate to make the information presented not misleading.  These financial
statements should be read in conjunction with the audited December 31, 1998
financial statements.  In the opinion of management, all adjustments
(consisting of only normal recurring accruals) considered necessary for
presentation have been included.

2.      SIGNIFICANT ACCOUNTING POLICIES

The Partnership uses the successful efforts method of accounting for oil
and gas activities.  Costs to acquire mineral interests in oil and gas
properties and drill and equip wells are capitalized.  Oil and gas
properties are periodically assessed and when unamortized costs exceed
expected future net cash flows, a loss is recognized by a charge to income.

Capitalized costs of oil and gas wells and leases are depreciated,
depleted and amortized by the unit of production method.

3.  REPORTING ON THE COSTS OF START-UP ACTIVITIES

In 1998, the AICPA issued Statement of Position 98-5 ("SOP 98-5"), Reporting
on the Costs of Start-Up Activities.  This statement requires costs of
start-up activities and organization costs, as defined, to be expensed as
incurred.  The partnership was required to adopt the provisions of SOP 98-5
effective January 1, 1999 and as a result has written-off the unamortized
balance of Organizational/Syndication costs as of that date.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                 OF FINANCIAL CONDITION AND RESULTS OF OPERATION
                    ATLAS-ENERGY FOR THE NINETIES-PUBLIC #6 LTD.


Management's discussion and analysis should be read in conjunction with the
financial statements and notes thereto.

Results of Operations
- ---------------------

Nine Months Ended September 30, 1999
- -------------------------------------------

Natural gas sales revenue for the nine months ended September 30, 1999 was
down $92,748 (8%) due primarily to declines in natural gas production which
decreased from 657,745 Mcf in the nine months ended Sept 30, 1998 to 586,848
Mcf in the current nine months.  The decrease in gas production results
primarily from normal declines in well production in the current nine months.
Natural gas prices increased by $.07/Mcf to $2.18/Mcf during the current
nine months.

Quarter Ended Sept 30, 1999
- ---------------------------

Natural gas sales revenue for the three months ended Sept 30, 1999 was down
due primarily to normal declines in natural gas production from 318,377 Mcf
in the three months ended Sept 30, 1998 to 171,701 Mcf in the current three
months. Natural gas prices increased $.43/Mcf to $2.45/Mcf in the current
three months.

Financial Condition
- -------------------

Liquidity
- ---------

The increase in cash provided by operating activities and distributions to
partners during the nine months ended Sept 30, 1999 results primarily from
higher cash received from sales of natural gas. The partnership's
working capital decreased 26% from $434,461 at December 31, 1998 to
$320,586 at Sept 30, 1999. The decrease is attributable to normal declines
in natural gas production from the levels at the end of 1998 which resulted
in lower receivables in connection with sales of gas produced.



Capital Resources
- -----------------

There were no new material commitments for capital expenditures during the
period and the Partnership does not expect any in the foreseeable future.
