The Quincy House tackle football team, led by its stalwart defense which has allowed only three touchdowns all season, battered Dwight-Silliman, 13-0, to give Harvard its only victory over the Yale Colleges in Friday's intramural tackle football competition.

"It's hard to believe we won, because we were missing four starters and almost didn't find the field in time," player-coach Gary Bravo said yesterday. "But we were very high for the game," he added.

In other games, Harvard champion Kirkland House was blown away by the Saybrook-Trumbull running attack, succumbing to the Eli champs, 21-3. Time ran out with Leverett House on the Brnaford-Edwards three yard line, as the Bunnies faltered, 14-8. Davenport-Pierson smashed fumble-ridden Winthrop, 28-0, while Stiles-Morse shut out Mather, 6-0 and Berkeley Calhoun whipped Eliot, 20-6.
