...will give tone signals for ten minutes every hour. Ordinarily this apparatus is used for short distances only, but it is hoped that the sound may be deflected by certain strata in the high atmosphere and thus by following a series of taugents to the globe, reach the south polar region. If the expedition succeeds in picking up these signals it is possible that direct communication by voice may be established for a short period each day. For the present, aerial broadcasts will be sent to Buenos and relayed to New York...

They quit early to have tea, rest their minds, study. Next day-a hot day -they moiled over discontinuous functions, convergent series, polar coordinates, second derivations. The finished papers were turned over to Professor Dresden at Swarthmore College. He was to announce results in ten days. Coaches for both teams agreed that fewer than four men on each side had been able to complete ten problems. They thought that one of the problems...
