The explanation for. the sharp divi-

rumor has it that the ‘Faculty were
able to force the contents of enough

it must be-said that the Faculty’ were
on their toes and deserved their 4-3
victory on the ground of superior
playing.

Miss Rice, who holds one of. the
top positions on the women’s first ten-
nis team at the Merion Cricket Club,
defeated Auchincloss, ’40, earlier in
the week. Lee, ’41; Whitmer, ’39, and
Walton, ’42, were the Varsity winners
in singles matches which required
Steady stroking and the ability to
cover the court. Mrs. Woodrow,
showing the effects of recent’ badmin-
ton, could have been more. accurate
in her returns to Lee, while Whitmer
defeated Mr. Broughtgn when she ral-
lied to win the third set.

Meyer, ’42, put up a good, defense
against Mr. Lattimore’s fast, aggres-
sive game, but .it was not ‘enough.
Lee and Auchincloss found themselves
in’much the same situation, and were
unable to cope with the excellent court
manoeuvering of Miss Rice and Mrs.
Woodrow, while Mr. Lattimore and
Mr. Broughton defeated Meyer and
Whitmer.
