After silently bickering with Teodoru and McCarty for ten minutes about how much time he had, the man left the podium. By that time the meeting had been cancelled.

As the crowd dribbled out of the hall, SDS speakers called for a march on the CFIA. Around 100 SDS sympathizers marched to the CFIA where the march broke up in confusion.

The speakers were escorted by University police across the lobby and down into Room 136 of Memorial Hall, from there they went out of the building and proceeded immediately to the Allston studios of WGBH Radio, which had broadcast the teach-in. The four spoke for nearly an hour over the radio.

The organizers of the teach-in had originally stated that both the South Vietnamese and Thai Ambassadors to the U.S. would speak at the teach-in. The Counselor for Political Affairs at the South Vietnamese Embassy in Washington and the Royal Thai Ambassador to Canada were the speakers who actually appeared.

University spokesmen repeatedly stressed the gravity with which they viewed the disruption. At an impromptu council of war late last night in the basement of University Hall-attended by Dean May and Dean Dunlop-Cox told reporters, "I couldn't over-emphasize the seriousness of it."

Immediately after the cancellation, Dean Epps angrily told reporters, "In the past, it has always been people from the outside who have been trying to tell us what we could teach and say. I guess we'll just have to get the radicals' permission before we have any more speakers here. Perhaps they could post a list of speakers who are permitted."

In a joint statement released last night, Dean Dunlop and Dean May said that "Professor Cox spoke eloquently for both of us."

"Tonight a minority prevented speech from being heard," the statement added. "We urge all those who cherish this University to join in condemning this deliberate breach of our most basic freedom."

Cox said, "I would hope that there are numbers of both Faculty and students who were willing to stand up and be counted on behalf of free speech by identifying those who disrupted."

Photographic records of the disruption will not be lacking. In addition to the two Harvard film crews, there were at least five news photographers from local media-some of whom will sell pictures to the University if it wants to buy them-and a film and sound crew from the United States Information Service.

Students for a Just Peace-which had earlier warned that it would seek both disciplinary and criminal action against anyone disrupting the teach-in-had four of its number present armed with cameras. The group also used a videotape camera to record faces of demonstrators.

Gary S. Golding '74, a member of SJP, last night said, "We have a lot of stuff, both witnesses and photos. We could get a lot of people in trouble; let's just put it that way."

Asked what the group planned to do with the evidence, Golding said, "We'd just like to make it a surprise."
