Bucking the strongest Harvard team encountered in recent years, the Big Green upset unanimous predictions and lost at Cambridge Saturday, 19-7. The Crimson played letter-perfect football for four periods. Capt. French of Harvard, aided by Guarnaccia, flashed a running attack of all-America calibre. Lateral passes, excellent punting, an aggressive line, fast, shifty backs and a stonewall defense against Dartmouth's line- plunging, all combined to defeat the Green.
