Sweeping first and second places in five events, Bill Brooks' freshman swimming squad took its second victory of the season by sinking Boston University 54 to 21 Saturday afternoon in the Blockhouse.

The first-termers from across the Charles looked like competition in only two events--the dive and the 200-yd. freestyle relay, both of which they won. The latter, a thrilling race from start to finish, grew more exciting as the Crimson almost came from behind.
