Details were the keynote at Soldier's Field yesterday, but one could sense the steadily rising tension and spirit as the Varsity worked through everything from signal drills to place-kicking.

Charlie Roche, Jim Noonan, and Jim Kenary led the passing drill, firing them long and short to every available end before the session turned to punting. Then the jayvees took over the role of the opposition party once again for the final hour of drill, running T plays against Varsity defensive units.

Cadets Will Pass

Although the jayvees threw no passes, the Cadets are expected to rely more on an aerial game tomorrow than they have in the past, since word has gotten around that pass defense is not the Crimson's forte. The same weakness has appeared in all of Army's encounters to date, and Harvard may be expected to retaliate in kind.

Army's main threat, however, is in a powerful running attack, engineered by Arnold Galiffa with the help of Bobby Jack Stuart, Win Scott, and Rudy Cosentino. Coach Valpey is relying on his same defensive team to stop this fleet combination.

Offense Not Decided

'The question of offense is yet to be decided, as the coaching staff did not go into the question of game strategy until last night. But probably the same unit will take the field against Army as faced Cornell, with the fullback post a toss-up between Chip Gannon or Paul Shafer. Hal Mofile is far enough back into shape to assume full-time duties once more in the second backfield.

A 120-man contingent leaves South Station for West Point at 8 a.m. this morning, and the team will arrive in time for an afternoon workout in Michie Stadium, that awesome plant in which the Cadets have produced 123 football victories since its construction in 1924. The superstitious can gain some solace from the fact that Harvard took one of the eight games Army has dropped in that time. But Army is particularly ferocious in its own lair, and they are not expected to fold tomorrow.

Army Coach Earl Blaik, in addition to his scouting information, has had the advantage of seeing the Michigan system before. His boys managed to eke out a 36 to 7 win over the Maize and Blue in 1946. And that was against the real McCoy.
