A portion of a diary outlining Arthur H. Bremer's plot to shoot former president Richard M. Nixon or former Alabama governor George Wallace belongs to the construction worker who found it, a judge ruled yesterday.

"The evidence is clear," Wisconsin Judge David Willis said, "that Mr. Bremer has not established that he owns it. This was abandoned property and becomes the property of the person who legitimately found it."

Sherman Griffin, of Dalton, Wis., found the 148-page manuscript at a Milwaukee bridge construction site Aug. 26, 1980. He claimed ownership and said he wants to sell it.

It lasted longer than many institutional offspring of the '60s, but inflation and the realities of politics and publishing in 1981 finally claimed the Liberation News Service, co-founded 14 years ago by author Raymond Mungo.

"It was a combination of things that did us in," said Andy Marx, 33, whose two stints as an LNS editor totaled more than eight years. "Staffing problems and the changing nature of the papers we serve were important. But it was inflation that was lethal, both for us and our subscribers."

LNS, which supplied news and photographs to 1,000 "underground" newspapers at its peak, was created at a convention of college newspaper editors in 1967. The twice-weekly LNS packets initially focused on campus disturbances and antiwar activity, and later expanded coverage to environmental, consumer, civil-rights and health-care issues.

John Carta, a daredevil parachutist out for "the sport of it," dropped safely from the skies yesterday to the roof of the 110-story World Trade Center, a quarter of a mile above the ground.

As soon as Carta, of suburban New Rochelle, N.Y., wrapped up his multicolored chute, a Port Authority police officer took him in for questioning. Officials later released him with a $50 summons for "unlawful parachuting."

"Maybe we should have invited Mr. Begin to step in," Anne Merete Petrignani said worriedly to her husband, Italian ambassador Rinaldi Petrignani, as they greeted guests last night at the Venini glass exhibit opening at the Renwick Gallery. Next door, Secret Service agents kept a careful watch over Blair House guest Menachem Begin -- even cordoning off the front of the gallery. Early guests were forced to enter through the basement, until, said Renwick director Lloyd Herman, "we were able to convince the Secret Service to let us use the front."

Among the guests on hand to view the 154-piece exhibit of colored glass made between 1921 and 1981 were Laura Venini Hillyer, the daughter of the late Paolo Venini, founder of the Venetian glass manufactory, and designer Massimo Vignelli.
