 no desire to eat. They finally lie down and unless 

 forced to rise will seldom get up again. The progress 

 of the disease is rapid, and losses are heavy. The only 

 remedy known at present is the use of a drench of hot

Kafir Corn and Sorghum. Cattle and sheep turned 

 into fields of Kafir or sorghum often die very suddenly. 

 This is due to the presence of prussic acid, which ap-

 usual drouth conditions. Thus the young growth of 

 both of these plants is a very dangerous feed; and stock
