The class races, postponed from Saturday, were rowed yesterday afternoon just before six. The race was announced to come off at half-past two, and at that hour a crowd commenced to gather at the Union boat-house. The roof of the boat-house was partially covered with spectators, and all along the street at the finish the walls were lined with men and boys, so that the scene was almost as lively as on Saturday. A stiff breeze was blowing up the course, making the water for the first half-mile very rough but from the sluice-way to the finish, the river was as smooth as could be wished. After waiting for an hour and a half, word came to the crowd that the race had been postponed till half past five, and in a few minutes the entire crowd had dispersed. When half-past five come, not more than half the number gathered again to see the crews come in. The crews had come out at the hour appointed, but had been sent back by the referee on account of the postponement. At length, at about halfpast five, the crews drew up in line, and everything was made ready for the start. The referee abandoned the "67" and took his station on the tug, filled with enthusiastic '87 men. After the preparatory "are you ready," at 5.40 the referee fired a pistol as the signal for the start. '85 caught the water first, but '84 made a beautiful start and took the lead. closely followed by '85, '87 and '86 in the order named. After a few strokes had been taken, '84 began to shoot ahead, and soon had a good lead, with the other three crews following about abreast of each other. The seniors never lost this lead but kept increasing it to the finish. At the end of the first half-mile the seniors were leading, followed by '85, who had crossed over and taken '86's water, then '87 and '86. After this the juniors commenced to pull away from the '86 boat at every stroke. '86 was not rowing in her usual good form, but was slashing considerable. The freshmen, meanwhile, were steering a perfectly straight course for the boat-house and made no attempt to get under the shelter of the wall. At the end of the mile, when the race was half over, '84 had gained a commanding lead, while '87 had crept ahead and was rowing about a length ahead of '85. The sophomores had fallen still more to the rear. From this point on, the race was settled for first place beyond doubt. The seniors, pulling in beautiful form, were getting over the course far more rapidly than the others, and it became simply a contest between '85 and '87 for second place, with '86 out of the race, her boat having taken in a lot of water. Eleven minutes and twelve seconds from the start, '84 passed over the line an easy winner by six lengths over '85, who, in turn, was three-quarters of a length ahead of the freshmen, and '86 last. The times of the crews were as follows : '84, 11m. 12s.; '85, 11m. 38s.; '87, 11m. 45s.; '86, 12m. The referee was Dr. C. H. Williams, '71.

The seniors may take pride in having won a fair and square race. They rowed in beautiful form throughout. The juniors pulled a good race, also, but not within three minutes as fast as the best time pull they have made. They rowed strongly and well together, but were seemingly unable to keep up with the seniors with their boat half full of water. The freshman surprised everyone by the way in which they pulled. They are really a remarkably good freshman crew, and show the result of last winter's hard work and their faithful practice on the water. '86 has been pulling in such splendid form that it was a surprise to everyone to see them come in where they did. They certainly did not do themdelves justice by their position, although they, too, had a boat half full of water.

The strokes rowed by the crews were as follows : At the start, '84 pulled 41 to the minute; '85, 37; '86, 36; '87, 39.

At the Crescent boat-house, '84 was pulling 38; '85, 37; '86, 34; '87, 40. At the pump, '84 had dropped to 35; '85, 36; '86, 32; '87, 36. Opposite the hotel Vendome, '84 was still pulling 35; '87, 36; '86, 32; '87, 36.
