THE MAIN WIRELESS STATION

CHE University of Wisconsin radio labora-
tory is the only university "lab" in the
country which is permitted to manufacture
the important pliotron bulb which is a funda-
mental part of every high powered wireless out-
fit. Professor Terry, director of the course in
wireless, is exhausting the air from a pliotron
bulb.
Many wireless students, after enlistment, have
been assigned to government schools for further
instruction, and in time will see actual service as
operators.
