To Uncle Sam Selective Service Number 3196 means simply another soldier for his peace time conscription army, but to Coach Dick Harlow and the Varsity football squad it means that next fall they will probably be without the services of Charley Spreyer, who yesterday was moved up to the first string tailback position in place of red-headed Don McNicol.

Spreyer's number was extracted from the 295th blue pellet fished out of the bowl in Washington, it was learned yesterday. Since he is a student he receives deferment until July, when he probably will be called into active service.

"If it had been the Irish Sweepstakes, I wouldn't have had a chance," the Crimson gridder asserted yesterday.

As the squad went through a lengthy afternoon of customary chores in preparation for the Princeton game, Spreyer got the call at first string tailback, indicating that he will probably be in the starting backfield on Saturday.

Movies of the Dartmouth game revealed that he turned in a good all-around job both on the offense and the defense. His steadying influence will be valuable Saturday with Loren MacKinney playing his first game as a blocker.

Conversions Stressed

Place kicking came in for more than the usual amount of attention yesterday as Hank Vander Eb, Joe Koufman, George Heiden, and Bill Barnes split the uprights time after time.

MacKinney seems to be fitting into the blocking back spot very nicely, but only a game can provide the acid test. Given a little more confidence in its blocking ability under MacKinney's leadership, the Harvard team has a good chance to find itself and put on a strong offensive display against Princeton. The Tigers have always been Dick Harlow's favorite opponents, and this Crimson eleven can match the 1940 Tigers man for man.
