West Point, N. Y., October 14--Coach "Biff" Jones diagnosis of the mistakes made in the Davidson game constituted the main part of today's workout for the Army team. He held a long skull session, pointing out the errors that his aides had noted, in an effort to perfect a smooth running machine.

After the talk the entire squad, dressed in sweat-clothes, went through a light workout on the field taking things easier than usual. The backs, ends, centers, and linemen all reported to their respective coaches for assignment instructions. A short-signal drill concluded the workout.

Stiffer practices and a good test against Harvard plays probably will be on the bill for the remainder of the week.
