Item 1.  Financial Statements

The unaudited Financial Statements of Atlas-Energy for the Nineties-Public #6
Ltd. (the "Partnership") for the period January 1, 2000 to June 30, 2000.

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
June 30, 2000, 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 $336,857 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

1.       INTERIM FINANCIAL STATEMENTS

         The financial statements as of June 30, 2000 and for the six 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
the 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, 1999
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.



                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  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

SIX MONTHS ENDED JUNE 30, 2000

Natural gas sales revenue for the six months ended June 30, 2000 was down
$86,103 (11%) from the prior year due to lower gas production. Gas production
for the six months ended June 30, 2000 was 275,979 Mcf, down from 415,147 Mcf
in the prior year. The decrease in gas production results primarily from
normal well declines. Natural gas prices for the six months ended June 30,
2000 increased by $.69/Mcf to $2.76/Mcf.

QUARTER ENDED JUNE 30, 2000

Natural gas sales revenue for the quarter ended June 30, 2000 was down
$18,116 (5%) from the prior year's second quarter due to lower gas
production. Gas production for the quarter ended June 30, 2000 was 134,924
Mcf, down from 190,533 Mcf in the prior year's second quarter. The decrease
in gas production results primarily from normal well declines. Natural gas
prices for the quarter ended June 30, 2000 increased by $.72/Mcf to $2.85/Mcf.

FINANCIAL CONDITION

LIQUIDITY

The decrease in cash provided by operating activities and distributions to
partners during the six months ended June 30, 2000 results primarily from
lower cash received from sales of natural gas. The Partnership's working
capital decreased from $297,913 at December 31, 1999 to $279,780 at June 30,
2000. The decrease is attributable to distributions to partners, higher
accounts payable and normal declines in natural gas production from the
levels at the end of 1999, which result 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.
