At this point rain began again and everyone headed for Building Seven, the main administration building. A 15-minute march through the building's winding corridors-chanting "Get off your ass, get out of class, end war research" and "John Brown, live like him, dare to struggle, dare to win" -ended with the demonstrators about a block away from the CIS.

Outside the CIS about 50 faculty and student members of the M.I.T. political science department and of the CIS stood in a "vigil for free speech."

"We support full discussion of the problem of war-related research," their statement read. "We affirm the right to non-violent political demonstrations on the campus."

"We deplore the closing of any building at M.I.T." the statement continued. "We oppose the use or the threat of the use of violence as a means for the promotion of change within the university."

The demonstrators read an "indictment and permanent restraining order" against four CIS members: Max Milikan, the Center's director; Lucien Pye; Ithiel de Sola Pool; and William P. Bundy.

At 2 p.m. the CIS group-about 700 strong-returned to the administration building and joined SACC in the rotunda. Outside Johnson's office were a small group of students and faculty members and several M.I.T. policeman. No Cambridge police were present.

After the group voted-first not to occupy the offices, and then not to occupy the corridors-they left and marched to instrumentation Lab Five at 45 Osborne St. Five uniformed MDDC police and several plainclothesmen were seen just inside the door-57 MDC police were reportedly assiged to Cambridge.

The group returned to the student center at 4 p.m., and about 600 spent the night there, watching films, listening to music, and planning today's strategy. Factions from various colleges held their own meetings before the full NAC tactics meeting which stretched well into the early morning hours.

Apples, peanut butter and jelly sandwiches, and hot dogs were distributed free, and some students went out to recruit more for this morning's picket line.

"This afternoon the Movement came to M.I.T. in force, an NAC statement distributed last night reads. "We have closed down the CIS and served notice on the M.I.T. administration that further, stronger actions are on the way in the days ahead."
