is apparent that mines can be worke
as profitably in these high ATTITUDES a
in our own country
DIR. Dastre, a French Psychologist
I who has been experimenting with AM
mails to determine the nature of sea
; sickness, reports that after they ha

cludes that similar disturbance pre-
duces seasicflness on board ships. CO
