Grubs in Cattle.

Last winter good many OF our
readers wrote to us complaining that
tumor-like lunches had appeared
upon the backs of their cattle and
they were at a loss to know what vas
the cause, while others on squeezing
the Jumps had found them to con ain
large Srubs. We explained that tEese
grubs came from the eggs of the OK
warble fly, which are deposited III der
the skin during fly time in SUMNER.

writing this article to remind our
readers that MARBLES can be prever TED

other insect pests of cattle. Despite

When it is seen chat flies are most
troublesome to cattle on grass we
think it will surely pay to spray their
backs with any one of the commercial
ny reporters. These applications al

in preventing warble fly attacks. To
the same end 1t Is well to provide
shade for cattle away from barn yards

themselves it will be observed that
cattle get as far away from these
places as possible during fly time.

this habit of cattle and the owner

for his stock away from the farm

of the cattle couple of times in late
fall, using a strong brine for the pur-

they hatch out and penetrate the
walls Of the stomach or gullet, gain
access TO the blood and finally work
their way through the flesh and other

this alleged life-history of the ox-war-
