346 Diseases of Sheep, 



the following as a very efficient ^^lick/' to prevent the disease 

 from spreading through a herd : — 



No. 392. Nitrate of potash, 



Sulphate of magnesia, 



Ground calamus, 



Laurel leaves, 



Juniper berries, of each, 2 lbs. 



Golden sulphuret of antimony, 1 lb. 



Mix well with the food, clover preferred, and give one-quarter night 

 and morning, for two days. 



This amount is enough for one hundred sheep. The same 

 author urges that great care be observed in regard to feeding, 

 so that the change from stable-feeding to pasture-feeding is 

 only to be allowed by degrees. In the morning the sheep 

 must not be driven to pasture until the dew and moisture 

 have entirely disappeared from the meadow, which depends 

 upon the temperature and weather. At noon a shady and 

 cool resting-place must be provided. 



Another preservative, as well as preventive, consists in 

 the application of cold shower-baths, which may be applied 

 to the herd by means of a squirting engine, the nozzle of 

 which is provided with a sieve, or by means of a garden- 

 spout ; the cold water to be applied at different times of the 

 day, and until the animals are perfectly cooled. The herd 

 may also be driven into cold or refreshing streams ; in case 

 of rain the herd must be allowed to remain exposed to it 

 at their pleasure. 



There appears to be a hereditary disposition to this dis- 

 ease ; it may therefore be presumed that in case of an ex- 

 traordinarily frequent occurrence among certain herds, tlie 

 sale of such sheep and the purchase of other stock will prove 

 the most profitable.
