filthy, decaying, and other vegetable refuse. They may be expected 

 on wet or low land in a dry season, or on high and naturally dry 

 land in very wet seasons, if the soil is rich in humus. In such lo- 

 calities, the different forms of anthrax make their appearance as 

 enzootic diseases. Foods that contain an abundance of nitrogenous 

 compounds, and are difficult to digest, or those of rank and rapid 

 growth, as aftermath clover, green rye, wheat distiller's mash, spoiled 

 or moldy garden vegetables, and smutty grain, may favor, possibly, 

 the development of anthrax. The most thrifty animals in a herd 

 become victims of the disease, contracting' it usually in its most 

 acute and malignant forms, while the poorer animals may escape 

 entirely, or take it in a mild form. It, is contagious alike in cattle 

 or sheep, and very difficult to destroy, as it is spread by the blood, ,

 fact that too much care cannot' be taken in securing the best sani- 

 tary condition of the herd. There is no specific for the disease, 

 hence the necessity of prevention. The sick should be separated 

 from the well at once, and the latter given free range in a pasture 

 where the water is pure. The period of incubation may be only a 

 few hours, or it may continue longer: In some cases the disease 

 runs its course in a short time, and in others it itakes much longer.
