the buildings, yards and runs. The most satisfactory method of destroying
lice on the bodies of animals is by washing or dipping in a water solution
or mixture of some reliable disinfectant or oil.

_Running hogs through a dipping tank_ that contains a one or two per cent
water solution of liquor cresolis compositus, or a coal tar disinfectant,
or that has from three-fourths to one and one-half inches of oil on top of
the water, is the most satisfactory method of destroying the hog louse.
Because of the thinness of the hog's coat and the danger from irritating
the skin when strong solutions of a disinfectant are used, most swine
breeders prefer crude oil as a remedy for lousiness in hogs. Crude oil may
be applied to the bodies of hogs with a swab. If this method is practised
instead of dipping, it is advisable to crowd the hogs into a small pen, and
apply the oil in front and between the thighs and back of the arms. This
may be practised during the cold weather when it is impossible to dip the
animals.

_Horses_ may be washed with a one or two per cent water solution of liquor
cresolis compositus, or a coal tar disinfectant. If the weather is cold, it
is advisable to pick a sunny day, and blanket the animal after rubbing it
as dry as possible in order to prevent chilling and catching cold.

_Cattle_ may be treated in the same manner as horses. Mercurial ointment
rubbed in small amounts on the skin back of the horns and ears, where the
animal cannot lick it, is a common remedy. The absorption of a small amount
of this drug does the animal no harm, but a larger quantity may salivate
it.

_Sheep_ are treated by dipping in a water solution of a reliable coal tar
disinfectant. This should not be practised during cold weather, as the
