Coach Harry Parker's heavyweight crew will row one of its toughest races The heavies, who will stroke against Penn and Navy on the Schuylkill River in Philadelphia have won both of their so far this season. Last week they out-rowed Princeton by five-and-a-half lengths, and two weeks ago they beat Brown by a length.

Penn has a potentially fine crew. Two years ago it beat Princeton by more than a length in a rough-water race. Navy, however, has had its troubles this year and is looking for its first victory.

Schuylkill is a difficult course because of a 15-degree turn right in the middle. Coach Parker, however, anticipates trouble with the course "as long as the coxswains do a decent job."

The lightweights will be racing Princeton and Yale on the Charles. Last week the lights beat Navy by over two lengths and two weeks ago they beat a highly-touted M.I.T. crew by almost three.

Coach Bill Weber said that neither Yale nor Princeton should be counted out. Princeton beat Navy by two lengths earlier in the season before loosing to Cornell. Yale finished in a dead heat with Dartmouth earlier in the spring, two lengths behind M.I.T.

Freshmen Challenged

The freshman heavyweights will have the toughest challenger this weekend, as they go against Penn and Navy in Philadelphia. Coach Ted Wash burn said yesterday that Penn's freshman heavyweight crew is rumored to be beating the varsity boat regularly. Navy's plebe boat, usually a slow starter each season, beat Cornell last week, which may indicate that the Middies are jelling earlier than usual.

The freshman lightweights have swept Columbia, M.I.T., and the Holy Cross varsity heavyweights in their three races this year. They may be slowed Saturday, however, as the four-man on the first boat is in Stillman Infirmary.
