Two of the Crimson's three crews, the varsity and JV, extended their traditional domination of local rowing Saturday afternoon with victories over MIT and BU. The varsity's win was more clear cut than it appeared to most onlookers who lined the banks of the Charles to watch the season's only some regalia.

Not until the race was substantially into the last quarter did the Crimson edge away from Tech, which had earlier stayed even with the winners and often led them.

M.I.T., however, was working at a 34 stroke during most of the race and stepped it up to 36 and 37 beginning with the last half mile, while Lou McCagg, making his debut at stroke for the Crimson, shrewdly held his boat down to a 31 or 33 1/2.

Stops Up Beat

When the Harvard boat finally stepped up to a 37 boat in the finish, M.I.T. completely collapsed and the Crimson crossed the finish line with a full length load. BU trailed three lengths behind the Engineers. It had been out of the race from the start.

The varsity's race was about as tough physically as any it will row until the four-mile haul with Yale in June. Not only was Tech a good competitive crew bat a strong headwind made the oarsmen put in work equivalent to that required for a two-mile sprint. In fact, the varsity labored under such poor rowing conditions that its time, 10:20.2, bad even for the beginning of the season, was higher than the J.V.'s 10:16.2.

The J.V.'s, rowing a slothful 31 beat almost to the finish, beat Tech by two lengths, with BU bringing up the rear.

MIT Lesee Load

Going under the Harvard Bridge, the one-mile mark, M.I.T. held a slight lead, which it relinquished a quarter-mile later. BU started with a 36 boat as all the crews did but when it tried to settle down along with M.I.T.'s 34, and Harvard's 31 power stroke, it quickly lapsed into the rear, with nothing to show for its winter racing experience in Florida.

Like its elders, Tech's J.V. grabbed an early lead. But the Crimson shell, which stroke Art Rouner never forced over 31 until the very last yards, caught up at the three-quarter mark and moved steadily ahead. M.I.T.'s and BU's times were 10:22.8 and 10:29.6 respectively.
