The first of the series of lacrosse games for the class championship will be played on Soldiers Field this afternoon at 4 o'clock, between 1910 and 1911. The Sophomores have a great advantage, as nine men played on last year's Freshman team, while the Freshmen have only three men available who have played before this year. The Juniors will play the Seniors on Friday and the final game will be played Monday.
