of new milk; tin's 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.
