YALE HAD SECRET PRACTICE

New Haven, Conn., Nov. 15.--The Yale team came through the Princeton game in good shape, with the exception of Wiedemann, who has a wrenched knee. An hour's secret practice, consisting of a blackboard talk and signal drill was Yale's only workout today, under Coach Shevlin and the other coaches. Secret practice will continue tomorrow. The team lined up today in the same order as on Saturday against Princeton, except that Allen took the place of Wiedemann.
