The annual spring interclass tennis tournament will begin at 2.30 o'clock this afternoon on the courts at Jarvis and Soldiers Fields. All undergraduates who entered have been divided into four groups by classes. The men in each division will play for their class championship, and the four winners will enter the final series for the College championship. The winners of the class tournaments will receive cups.

In the preliminary rounds, the matches will be for the best two out of three sets; in the finals, for the best three out of five. Deuce and advantage sets are optional only in the semi-finals. Matches must be played on the day scheduled or defaulted. If a player is more than 30 minutes late, he will lose by default. Courts will be reserved for the matches, but players must supply their own balls. In order that the tournament may not be too prolonged, it will be necessary that some contestants play two matches this afternoon.

Score-cards have been placed in the CRIMSON Office, where the results of the matches must be posted by the winners before 6.30 o'clock on the day of the match; otherwise, both contestants will be considered out of the tournament. No man who is on probation is eligible to play.
