When Washington residents dial WEather 1212, they hear a sweet-voiced
lady predicting the weather over and over again. Those who would
like to enjoy the voice indefinitely are cut off automatically
after about nine reports. A $20,000 telephone company gadget
provides this unique service. The report, as read by a young
lady selected for clearness of speech, is recorded on an endless
wire tape by magnetizing the molecules in the tape in proportion
to the variations in the audio signals. The message can be erased
by a second magnet in preparation for re-recording whenever
the U. S. Weather Bureau decides to change its prediction.
A St. Louis resident complained to the sheriff's office that
his chickens were being shocked by an electric fence put up
by a neighbor. The deputy who investigated found that a bare
wire, supported on insulators at the level of a chicken's head,
had been erected around a flower bed to discourage destruction
of young plants by the chickens. Since this fence was on private
property, the law decided the neighbor was entirely within his
rights in maintaining the fence. The officer gave orders, however,
that a sign be erected warning that the fence was charged. It
is now up to the complainant's chickens to learn how to read.
Experiments in the transmission of orders by radio from the
central control tower of a railroad freight yard to switching

for this purpose from the Federal Communications Commission.
Construction permits were issued for two 15-watt stations, one
operating somewhere between 300,000 and 400,000 kc., and the
other being assigned to four different frequencies in the range
from 35,000 to 40,000 kc. This newest application of radio may
mean hundreds of additional jobs for men with radio training.
