Yale Eleven Engaged in Secret Signal Practice

New Haven, Conn., November 9, 1915.--The Yale football team held a secret practice today and will probably do so for the rest of the week. The greater part of today's practice was devoted to signal drill and dummy work on the team's offensive. No scrimmage was held.

B. C. Chamberlin had charge of the dummy tackling of the University team for the first time today. Scovil's hand has shown much improvement and may be well enough on Saturday to allow him to play in the Princeton game.
