bolic solutions, pine tar, oil of tar, fish oil,
laurel oil, oil of citronella, oil of sassafras, oil of camphor, and
cod-liver oil. These things must be used judiciously or they will result
in poisoning or removal of the hair from the animal in some instances.
Ten per cent oil of tar in Beaumont oil or in cottonseed oil was found
to be safe and efficacious by Graybill.

The use of the fly-maggot trap noted under stomach worms of the horse,
and of the various forms of the Hodge flytrap, is recommended.

FLEAS.

The flea of man and those of poultry, when numerous, will bite the horse
and give rise to rounded swellings on the skin. To dispose of them it is
needful to clear the surroundings of the grublike larvae as well as to
treat the victim. The soil may be sprinkled with quicklime, carbolic
acid, coal tar, or petroleum; the stalls may be deluged with boiling
water and afterwards painted with oil of turpentine and littered with
fresh pine sawdust, and all blankets should be boiled. The skin may be
sponged with a solution of 1 part carbolic acid in 50 parts of water.
Other animals should be kept free from fleas or kept away from the
vicinity of the stable.

The chigoe (_Pulex penetrans_) of the Gulf coast is still more
injurious, because it burrows under the surface and deposits its eggs to
be hatched out slowly with much irritation. The tumor formed by it
should be laid-open and the parasite extracted. If it bursts so that its
eggs escape into the wound, they may be destroyed by introducing
chloroform into the wound.

LICE, OR PEDICULI.

Two kinds of lice attack the horse, one of which is furnished with
narrow head and a proboscis for perforating the skin and sucking the
blood, and the other--the broad-headed kind--with strong mandibles, by
which it bites the skin only. The poor condition, itching, and loss of
hair should lead to suspicion, and a close examination will detect the
lice. They may be destroyed by rubbing the victim with sulphur
ointment, or with sulphuret of potassium 4 ounces, water 1 gallon, or
with tar water, or the skin may be sponged with benzine. The application
should be repeated a week later to destroy all lice hatched from the
nits in the interval. Buildings, clothes, etc., should be treated as for
fleas.

STINGS OF BEES, WASPS, AND HORNETS.

These are much more irritating than the bites of flies, partly because
the barbed sting is left in the wound and partly because of the quanti
