The $10-million Columbia gymnasium was planned for an area that many of these youths use as a playground.

Brown emphasized that this fight was the community's too. He and Carmichael left after about an hour. They were scheduled to speak in Newark tonight.

Two Factions

The campus is severely split into two factions--those who are sympathetic with the demands of the demonstrators and those who want them expelled.

The sympathetic faculty group, called the Ad Hoc Committee, vociferously booed Vice President David B. Truman last night when he announced that Columbia was ordering outside police onto the campus. Several distinguished faculty members associated with this group have threatened to resign unless the demands are met.

The other faculty group, led by Warner Shilling, a government professor, has said that it will make no concessions to the demonstrators. One faculty member reported that Shilling said at a meeting last night, "Either Rudd goes or I go."

Shilling is faculty leader of a group of several hundred conservative students, many of them campus athletes, who call themselves the Majority Coalition.

A leader of the Coalition, Frank Dann, a member of the swimming team, claimed that the administration had promised him that SDS demonstration leaders would be expelled.

Dann's group continually harassed the demonstrators today, but there were no incidents of violence this time. Last year conservative students and SDS members came to blows during a demonstration against Marine recruiters.

Beat Twenty Dollars

Still, tempers were high. One student complained that while the University was closed he was missing classes. "That costs me twenty dollars a day," he said. "And I'm going to beat that twenty dollars out of one of those SDS kids when I get my hands on him."

Last night, members of the Coalition came to the steps of Fayeweather and demanded a chance to "get even" with the demonstrators inside. "Three years of the administration giving in to SDS is a long time to restrain ourselves," one said.

Low Library, the huge Roman-style building where Columbia President Grayson Kirk has his offices, remained the focus of attention today. Professor Robert Fogelson announced that students would no longer have free access to the building.

He explained that if the demonstrators left the building they would have their identification cards confiscated and would be unable to re-enter. Food and messages could be brought inside however.

The first to leave was Gary Menaged, who said that his father had wanted to talk to him about the demonstration. Menaged, who had been inside the library for two days, said that he did not know he could not return.
