The seating in the first University shell for the triangular regatta in the Charles River Basin this Saturday was still uncertain yesterday afternoon when it was reported that C. E. Mason '30 would probably be unable to row until Monday of next week. C. McK. Norton '29 rowed at No. 4 in Mason's place in yesterday afternoon's workout and will take his place Saturday unless the Sophomore's hands heal more rapidly than is expected.

With Norton out of the second crew D. S. Greer '29, who has been stroking the Junior class eight, was moved to No. 4 in the second University shell where he will row. Saturday if Norton fills Masson's position in the first eight.

The lineups for the first two 150-pound crews are still uncertain but Coach C. S. Heard '25 will probably decide on the order in which the men will be seated for the races at the end of the week after this afternoon's practice. R. H. Miller '30, who is now eligible, having completed his language requirements, is giving R. W. Herr '28 a hard fight for the coxswain's position in the first 150-pound shell.

The Sophomore crew which will race the Yale class championship combination at Derby this Saturday is as follows:

Stroke, J. L. Batchelder '30: 7, H. W. Sturges '30; 6, G. P. Hamlin '30; 5, C. N. Comstock '30; 4, R. A. Page '30; 3, Roger Donaldson '30; 2, R. S. Mitchell '30; 1, J. S. Wintringham '30; cox., either D. F. Baum '30, or L. L. Wadsworth '30, E. H. Daniels '30, and E. H. Wilson '30, will also make the trip as substitutes.
