This species varies much in the tint of the colouring, and in 

 the length of the hair in the different seasons. In summer they 

 are covered with very short, elosely pressed fur, letting the skin 

 be seen between the hairs. In the cold weather, and in England, 

 the fur is longer and more abundant. The hair of the chin and 

 neck is long and rigid in all seasons, and even in the young ani- 

 mals. The tail of the adult specimen is cylindrical and nearly 

 bald, ending in a tuft of black hair ; in the young specimens, 

 especially in the winter fur, the base of the tail is fringed with 

 hair on each side. The male is much brighter-coloured, and the 

 chest and belly are nearly black, like the legs. The hinder parts 

 of the rump of the young animals are greyish white ; in the older 

 specimens it becomes pure white and broader in extent.

 not think their flocks of cattle will be healthy or fruitful unless
