Four new developments, including an offer of assistance from the Transport Workers Union of the CIO, occurred at strike-bound Yale over the weekend. Last night negotiations between the university and the union were still deadlocked.

Michael J. Quill, president of the Transport Workers Union of America, offered "all our support" to the independent Federation of Yale University Employees Friday night, but the Yale union declined "at this time."

Last official word from the university was President Whitney A. Griswold's statement earlier in the week that he did not see how the union demands for a ten-cent-an-hour wage increase could possibly be met. "We have strained our resources to the limit," he said.

At the power plant Yale police arrested a picket captain in the weekend's only near outbreak of violence. The captain attempted to halt the passage through the picket lines of an oil truck. When he resisted a police order to permit the truck to pass, a momentary struggle between pickets and police broke out but quieted with the captain's arrest. Last night he was out on $100 ball.

Elsewhere picket lines were being broken consistently by non-union members, students, and faculty.

One faculty member, however, refused to cross the picket lines and held his Saturday classes in the office of the Yale News.

New Haven's Park Commission denied a request by the union to hold a demonstration the n citoy green Saturday. The commission gave no reason for its refusal.

Students are still being inconvenienced relatively little. By Saturday, however, steam heat for the gymnasium had been cut off.
