The book isn't closed on this one, but as of last night the future of George S. Dunlop as assistant secretary of agriculture for natural resources and environment continued in doubt.

As House and Senate conferees met to work out differences in their respective fiscal 1988 agriculture appropriations bills, House Chairman Jamie L. Whitten (D-Miss.) refused to budge from his position that he wants Dunlop out.

The House committee would abolish Dunlop's job to show its displeasure with his handling of soil conservation programs, including his backing of White House positions calling for sharply reduced conservation spending. Whitten, a strong supporter of the programs, retaliated by moving to wipe out Dunlop's job.

Senate conferees protested yesterday that Whitten's action was undercutting the Senate's confirmation role, but the doughty chairman wouldn't move. "We're clearly within our rights and we're clearly within the facts," he said.

Whitten, however, indicated that he might compromise. "We will see where he can be assigned to work {elsewhere} with the secretary," he said. Lands of No Name . . .

The day Soviet leader Mikhail Gorbachev left Washington, the Federal Register published presidential proclamation 5752 -- Human Rights Day, Bill of Rights Day and Human Rights Week, 1987.

But the "countries where monopoly power rests with a single group or political entity" are not named. Nuclear Tourism . . .

There's always a local angle if you look hard enough. In the post-summit rush, the office of Sen. William L. Armstrong (R-Colo.) issued a press release heralding Pueblo, Colo., as "a focal point for the nuclear disarmament effort the two superpowers have now begun."

Armstrong said the shells and fuel of up to 450 Pershing missiles would be destroyed at Pueblo over a three-year period. "The Pueblo Army Depot is going to become a favorite tourist attraction for Soviet visitors," he proudly noted. Bipartisan Partners . . .

New in Town: The Jefferson Group. The recently formed public affairs and communications firm is described by vice president William Keyserling, who directed the 1984 presidential campaign of Sen. Ernest F. Hollings (D-S.C.), as a "bipartisan operation." The firm's president is Mark D. Cowan, formerly a Reagan administration appointee at the Labor Department.
