scne and 2 parts of raw linseed oil. If a quick cure is impera- 

 tive a half-and-half mixture may be used. Robinson in Farm 

 Poultry, May, 1907, recommends a quick and easy method of 

 applying this. It is to take a tall quart measure of the liquid to 

 the hen house at night and dip both legs of each infected bird 

 into the measure of oil, holding them there for a moment and 

 then allowing them to drip for a moment more and then re- 

 placing the hen on the roost. With any treatment which in-

 feathers of the leg, as this causes irritation and sometimes burns 

 the skin much as the human skin is burned when it is rubbed 

 with kerosene and covered with flannel. 



A second method of applying kerosene is to put a teaspoon ful 

 of the oil in a quart measure of w^ater and treat the birds by 

 the method given above The same care should be taken not to 

 wet the feathers.

 application to a number of birds.
