pears weak, growing weaker and thinner, the skin seems 
to shrink upon the body, and there is a slimy discharge 
from the body, and whev the chick eats it is usually 
with difficulty, and as the supposed disease advances it 
seems almost impossible for the chick to swallow, finally 
refusing to eat. When any or all of these symptoms ap- 
pear, then examine the under part of the head and the 
throat and at the sides for the head louse, and nine 
times out of ten he will be found snugly at home among 
the down or sprouting feathers; then apply two-thirds 
glycerine, one-third carbolic acid,and five times as much 
water as the above mixture.” 
A few general measures will answer for all kinds of 
lice. To smoke them out is a very thorough way, if the 
house is tight enough to hold the fumes. Where the 
house can be made tight an excellent plan is to fumigate 
it with pure carbon bisulphide once every two months. 
This is done by simply pouring the bisulphide into an 
open saucer, using about one pound for each one thou- 
sand cubic feet of space in the house. Close the house 
tightly, and leave for at least twelve hours. Bisulphide 
of carbon is very explosive, and must not be brought 
near a fire or light. It is very sure, and will kill any 
insect. Besides sulphur, already mentioned, tobacco 
stems are very commonly used for smoking. The smoke 
must be very dense, and should remain in the house at 
least twelve hours, If the first smoking does not kill 
all, repeat the operation. Another good way is to drench 
the roosts with kerosene or hot water, followed by white- 
washing, and the use of tar on the ends of the poles and 
wherever they come in contact with supports. The ad- 
dition of four ounces of crude carbolic acid to the gallon 
of whitewash increases its efficiency for this purpose. 
Repeated applications may be necessary, but due atten- 
tion to reaching all points to which the pests resort will 
keep the nuisance in check at least. For the red mites
