 and under the wings will keep down the lice for a 

 time, but the dusting must always be done twice at 

 intervals of five or six days, so that the nits which 

 hatch after the first dusting may be killed. 



Dipping in sheep dip, tobacco water or kerosene

 fowls free from lice a whole season or longer, but it

Blue Ointment A mercury preparation which is 

 recommended by many experiment stations, is said 

 to be very effective in ridding the hens of lice, but
