Eisenhower Calls Berlin Meeting As Russians Suggest Negotiation; Soviets Protest Boarding of Ship

LEIPZIG, East Germany--Soviet Premier Nikita Khrushchev eased away from his May 27 deadline on Berlin in a free-wheeling talk Thursday and offered lightly to sign a Western-drafted German peace treaty.

He said his deadline for an end to the four-power occupation of Berlin might be postponed, if the West will negotiate sensibly, until June 27 or maybe July 27.

At the same time he reiterated that the Soviet Union will sign a separate peace treaty with Communist East Germany, an eager potential heir to Soviet occupation controls, if the West refuses to sign an all-German treaty.

President Eisenhower Thursday asked Democratic and Republican congressional leaders to a White House conference Friday on the Berlin crisis and German problems generally.

Soviets Protest Boarding

MOSCOW--The Soviet Union Thursday denounced the U.S. detention of a Soviet fishing trawler off New Foundland as a provocative act.

A protest said the trawler Novorossisk was fishing on the high seas Feb. 26 when she was suspected of cutting the transatlantic cables and was boarded by a party from a U.S. destroyer.
