Princeton, N. J., November 3.--The Princeton eleven was given an hour's scrimmage with the scrubs today, the first half being devoted to defensive work against Harvard formations used by the scrub eleven, and the second half to offensive play. It took the Varsity a long time to diagnose some of the Harvard plays, but after they had warmed up to it, scrub gains were rare. The scrubs did not score but the Varsity made two touchdowns. Special time was given to catching punts against the sun as it will have to be done in the Stadium, Law, Tibbott and Dickerman practised drop-kicks. Law was decidedly off form but the others performed creditably. Some time was spent at the end of the practice in developing the punch which has been lacking recently. The Varsity was given the ball on the 15-yard line and scored several times from that point. The work-out was the hardest this week and the showing of the men throughout very satisfactory.
