The class races, for which the crews have been working since the first part of the college year, will be rowed next Saturday afternoon, at 3 o'clock. The course will be practically the same as that rowed in previous years, but will have to be changed slightly on account of the new bridge. As now determined the course will start from a line drawn three hundred feet from the coal sheds below the railroad bridge and parallel with a line drawn from Otter street near the Union boat house; the latter is to be the finish. The course is so arranged that two crews will pass through the first span of the Harvard bridge on the Boston side of the draw, and one through each of the adjacent spans on the Boston side of the draw. A meeting of the captains of the class crews was held last evening in Captain Herrick's room to arrange the preliminaries and draw for courses. The draw resulted as follows: The seniors will row over the inside course, or that next the wall; the freshmen come next, then the sophomores, and the juniors will have the outside course. This gives the seniors a slight advantage, especially if the day is windy or the water rough. The juniors and sophomores will have to pass through the same span. The officers of the race have not yet been appointed. Each crew will have two judges, one on the referee's tug, and one at the finish. All the crews at present seem to be evenly matched. Eighty-nine has been considered for some time as the fastest crew; Ninety is showing up well altough seldom seen; Ninety-one may be said to be rowing fairly well. The freshmen will probably make a much better showing than freshman crews of recent years. The make-up of the crews with their weights will be as follows:
