The heavy curtain of secrecy which annually falls at Soldiers Field several days before the Yale game, forcing writers to twiddle their thumbs in Dillon Field House instead of freezing their hands outside by the Stadium, will descent today and tomorrow as the varsity prepares for Princeton.

It is the first time that Lloyd Jordan has ever had to close practice before the Princeton game. But it is also probably the first time he has had very much to hide from Charley Caldwell.

There are a great many things that Jordan may try in these two days. With Bob Hardy-resting comfortably after an operation-out for the season, Jordan must find a new quarterback. And in the process he may bring up a brand new formation.

He might, for instance, go into a straight T formation. When Cal Lowenstein first came back from the service, A T loomed probable. But Lowenstein's early injury delayed those plans considerably. The Crimson did use some T plays, however. Against B.C., after an unsuccessful first half of single wing plays, it abruptly switched into the T. Lowenstein went under center, Dick Clasby went into a normal left half position, Brian Reynolds was at right half, and John Culver at fullback. The varsity, which had been almost completely stymled until then, had little trouble moving through the B.C. defense. Reynolds looked smooth on straight cross bucks, and Clasby and Lowenstein teamed up well on passing combinations. Culver, of course, ran hard, as he does from A, B, C, D, and E formation.

Now that Jerry Marsh, second string blocking back, has returned after a leg injury, the Crimson might stay with its straight wing, alternating Clasby and Lowenstein at tailback. Or it might try a double wing or A formation, or any number of possibilities. There is no doubt that it would be advantageous to have both tailbacks in the same formation.

W. Henry Johnston, Director of Sports information, will hand out daily releases on the practice sessions. But they won't tell what happened. A lot of people would like to know just what is going on. Close to 40,000 of them are interested enough to show up Saturday to find out.
