 be in the fluff around the vent and on the lower side of 

 the body and in the fluff under the wings. Its efficiency,

 exercised that a reinfestation is not brought about 

 by the introduction of lousy birds. 



The lousy henhouse should be thoroughly and 

 frequently cleansed and the walls whitewashed.
