<ottles, which were left to evaporate; and after a week I refilled, 
and so again the third week, when I could see that all the flees dis- 
appeared by degrees. 
We were delighted, as we could not go to the chicken house, 
the road was so covered with the pests. To put the foot one second 
in the sand was enough to cover them with little fleas. I hope no 
one else will have so many, hut there are a great many in this State 
who cannot keep poultry to advantage for this pest. 
Hoping you will use this whenever convenient, as I am ready tc 
vouch for it at any time, I remain

CARBON BISULFIDE FOR HEN LICE. 
The following is from Dr. Schneider, in the Paris Journal dt 
V Agriculture on Sulfide of Carbon for destroying lice : 
“The very next day after using it I was agreeably surprised to 
find that the enemy had left leaving none but dead and dying be- 
hind, and on the following day not a single living insect was to be 
found, while my birds were sitting quietly on the roosts enjoying an 
un wontedly peaceful repose. This lasted for twelve days, till the 
Sulfide had evaporated. Twenty four hours later a fresh invasion 
of lice had put in an appearance under the wings of the birds in the 
warmest portions of the house, where there were no currents of air. 
I replenished the supply of Sulfide, and the next morning only a 
few of these were remaining. The next morning every trace of the 
vermin had disappeared. Since that time I have personally made a 
great number of further trials with the Sulfide, with immediate 
and absolute success. I should rec'ommend the Sulfide of Carbon 
to be put in small medicine vials hung about the pigeon house or 
poultry roost. When it has about three parts evaporated the 
remainder will have acquired a yellowish tinge, and no longer acts 
so completely as before, but if it be shaken up afresh it will suffice 
to keep the enemy at a distance.” 
In relation to the above Mr. Taylor says; 
“I should think a few small bottles of it tied to the perches as 
indicated, would be very efficient, as when the chickens roost their 
feathers would come almost down to the mouth of the bottle ; 
though the vapor naturally goes down, the law of diffusion of gases 
will cause enough of it to go upward to be sufficient, as the writer 
indicates.” 
I have used Bisulfide of Caibon for the common gray and small 
red lice, and never found anything to equal it for effectiveness and 
ase of application. Place in open mouth vials and hang them un-
