rance they multiply amazingly. They live in cracks and 
crevices of the house and under the perches during the 
day unless they are very numerous, when some may be 
found on the fowls at any time. The mixture described 
will destroy them without fail, if faithfully used. Poultry 
houses should be painted with this lice-killer at least 
once in a month, and oftener if lice are found. If there 
are any present they may be found by lifting up the 
perches, as they cluster together and are at once revealed 
by their intense red color, the color being that of the 
blood on which they have gorged themselves. 
Every poultry house should have a dust-box in it, as 
dust is the natural lice-killer for fowls and if they are 
furnished with a supply of it lice will rarely get a very 
good foothold in the flock. The Iowa station gives the 
following directions for making cresol soap and recom- 
mends it for disinfecting and killing lice and mites: 
Shave one 10-cent cake of laundry soap into 1 pint of 
soft water; heat or allow to stand until a soap paste is 
formed; stir in 1 pound of commercial cresol and heat- 
or allow to stand until the soap paste is dissolved; then 
stir in 1 gallon of kerosene. For a lice-killer use undi- 
luted, painting the perches and sides of the house with 
a paint brush. If used as a spray add 50 parts of water 
and stir. This will make a milky fluid which may be 
used in the sprayer. Cresol is a coal-tar product and 
druggists supply it. 
LIMBERNECK.—This is a disease in which the fowl 
loses the power to hold its head up, and often the neck 
-is twisted. It is usually caused by eating decaying ani- 
mal matter, although on rare occasions it may be caused 
by eating some other poisonous matter. To prevent it 
bury or burn at once all dead animals or fowls. To
