of new milk; this is about the proper dose for twenty-five 
hens. The sulphur passing off through the pores in the 
skin helps greatly to kill the lice. Whitewash the walls, 
ceiling, roosts and nests and put clean straw in the nests. 
This effects a complete cure. If the lice are in other build- 
ings treat in just the same way. 
This treatment for killing hen lice will also kill the 
germs of other diseases, such as roup, etc., and is a process 
through which a hen house should go every fall and spring 
to keep disease from the fowl. It is also a good plan to 
thoroughly spray the house by blowing coal oil into the 
cracks and crevices and about the roost and nests before 
whitewashing. An ordinary spray pump may be used. 
2. Scaly Leg. 
Causes. — Scaly leg may be transmitted from one fowl 
to another. Dirty, filthy quarters is the most frequent cause. 
The scales are the result of a parasite burrowing into the 
skin of the shanks and toes. 
Symptoms. — It appears 
as a rough, warty, dry de- 
posit on the legs and toes. 
Treatment. — Place a table- 
spoonful of lard on the 
stove and warm it, remove 
from the stove and add an 
equal quantity of coal oil. 
Saturate the legs and toes 
once a day with this solution, 
applying it with a stiff fea- 
ther or varnish brush. Con- 
tinue this treatment until 
the scales may be easily re- 
moved or fall off. Keep the 
fowls' quarters dry and clean 
and see that lice are not 
present. When the scales fall off, apply a little of the white 
lotion or vaseline.
