What is expected to be a very important meeting of the Yale Athletic Committee has been set for this evening. The meeting was originally scheduled for last Wednesday but was changed. The reason for the change, it is understood, is business connected with the searching investigation into Yale football which was carried on during the past season, and which resulted in the appointment of a special football committee, which has been preparing a report of several football matters, incidentally one on the question of head coach, which was not ready last Wednesday.
