Contagion must, therefore, be accepted as the cause of this plague, and it should be guarded against on the same principles as are the infective elements of other communicable diseases. Treatment.— Young cliickens hatched under hens almost invariably have lice ujion them and should be treated as soon as removed from the nests. An effica- cious and safe remedy in this case is pure lard. It should be carefully rubbed into the feathers upon the top of the head and under the throat. Lard obstructs the breathing pores of the lice and soon kills them. Nothing should be mixed with the lard to increase its activity as such young birds are very sensitive to the action of irritants and are seriously injured by them. Some recommend mixing powdered sulphur with the lard for this purpose; but it should on no account be used on small chickens as it causes inflammation of the eyes and arrests the growth. Pure lard is harmless and will kill the lice, con- sequently it can be used with full confidence. A small quantity may also be rubbed under the wings, but this is not usually considered necessary until the chicks are a week or two old. Chickens hatched in the incubator should be free from lice, and will be unless the incubator has in some way become infested. It is well to examine even in- cubator chicks occasionally for lice as the incubator or brooder may have these insects introduced into them in various ways and then become favorable places for the growth of the parasites as well as for the develop-. ¥\g. 42— Lipi'iirua caponis.
