NEW HAVEN, Conn., Nov, 24 Two problems one mechanical and one psychological have held the spotlight of attention for Ducky Pond this week as be sent the Yale squad down the home stretch, bound for the climactic clash in the Harvard Stadium tomorrow.

First of all, the Blue Chief-of-Staff has been concerned with a remedy for the faulty blocking in his backfield which has sapped a good deal of the Bulldog's offensive strength throughout the season. And secondly he has had to face the task of building his embattled Elis up to a high emotional pitch which came so near to carrying them to victory over the Princeton powerhouse.

Both Problems Solved

According to the late reports from the Blue camp both of these problems have been satisfactorily solved. The solution of the first involves Bill Starbuck, success-story Sentor, whom Pond has selected to start in the first backfield as blocking back tomorrow. Up to two weeks ago, Starluck was a little-known understudy for Captain Bill Stack at center, and for this very reason his appearances in games had been few and brief.

But in recent practices he has shown that he has a valuable contribution to make as a dependable blocking back. The veteran Hank Wood, and Fred Kieckhefer, a Sophomore who came up from the Junior Varsity to face Brown is this capacity, will be ready to take over should Starbuck not be up to scratch against John Harvard.
