DISEASES OF POULTRY. 



appearance of dried bread. As the crust thickens by 

 deposits on the inner surface, the cavities first formed 

 become smaller by the drying of the walls surround- 

 ing them, and the Sarcopt abandons this location for 

 a position nearer the flesh, where there is more mois- 

 ture. The mites are, there- 

 fore, only found on the in- 

 ner surface of the crust, 

 although the cavities or 

 honey -combed appearance 

 exists throughout the 

 whole substance. 



Treatmen t. — When 

 this disease is first observed 

 in a flock, prompt and 

 energetic measures should 

 be adopted to eradicate it. 

 The affected birds should 

 be isolated to prevent the 

 spread of the contagion. 

 The houses which they 

 have occupied should be 

 thoroughly cleaned. The 

 roosts and other woodwork 

 should be scalded with 

 boiling water or covered 

 with carbolated lime wash. 

 The treatment of the af- 

 fected birds is the same as 

 with scabies of the body, 

 with the single exception that the loosened scales must 

 be removed in order to bring the remedy in contact 

 with the mites. In order to accomplish this the legs 

 should be soaked for a sufficient time in warm water
