CHICKEN LICE.


ogists OF the department OF agricul-
ture have discovered. This inexpen
siye white powder, they find, will rid
a flock OF all the seven common
species OF chicken lice in few days.
One pound, costing only 40 or So
cents at the time OF this writing, is
enough to treat 100 fowls. II Quoted

as far. 1t is easily applied, economi
cal, gives immediate results, and
does not injure the fowls or the poul
tryman.
The complete effectiveness OF the
sodium fiuorid remedy and methods
OF using IL are discussed in Farmers
Bulletin sol of the United States De-
partment of Agriculture, "Mites and
Lice on POULTRY by f. c. Bishopp
and H. +. Wood The bulletin deals
also with mites, the night pests OF
chickens. which requires a different
treatment. Lice are the biting in
sects that work by day and are a ser
ious foe in neglected small focks of
general farm and back yards.

the druggist or you may get sodium

use against cockroaches. and still
more recently against poultry. this
substance had not been employed as
an insecticide. The demand for It,
therefore. has been quite limited.
and IL is not ordinarily found in the
stock OF the small drug store. Drug
gists, however, can obtain II readily
from manufacturing chemists, and
with demand il likely will be carried
by local dealers. The finely powder
ed commercial form Is cheaper and
more easily applied by the busting
method than the fine, crystallized
sodium fluroid

To apply the material in dust
form, place Ii in an open vessel on
table and with one hand hold the
fowl by the legs or wrings. With
the other hand place small pinches
of the chemical among the feathers
next to the skin, according to what
Is known as the pinch" method
thich proceeds as follows: One

me below the vent. one on the tail
ne on either thigh, and one scatter
on the under side of each wing
,hen spread Each pinch can be dis
.ributed by pushing the thumb and
pgers among the feathers as the
aterial is released. If the chicken
held over the vessel the material
lich falls from the fowl during the
beration is recovered.
The material also may be applied
means OF a shaker, but this meth
has some disadvantages as com
