Harvard's Committee for Wallace will join with other Young Progressives and with the Longshoremen's Union this morning in picketing the "scab ship" S.S. Mount David, currently docked at Commonwealth Pier.

The ship arrived from the West Coast last week, but has not been unloaded because she left that area in violation of a Longshoremen's strike there.

The student picketers leave from in front of Harvard Hall at 6:45 a.m. in a jeep and a trailer rendezvousing with other Greater Boston Y.P.A.'s at their intown headquarters. The demonstration is set for a half hour, beginning at 7:30 a.m. and will feature singing by HCW chairman Richard Stone.
