sheep. Both male and female in Dorset sheep are horned, while the 

 Suffolk breed are both hornless. 



The Rocky Mountain Bighorn (Figure 230) is a large strong an - 

 mal adapted to its life on the mountain top. It is valued for its 

 massive horns and its flesh. The Chamois of the European Alps,

Rocky Mountain goat is not a true goat, but is our only native goat- 

 like species. It has very high shoulders, thick legs and a long face. 

 It lives just above the timber line on high mountains and has ex- 

 ceedingly sharp hoofs adapted to ice and snow. 



The true goats include the Spanish Ibex, the Steinbock of the 

 Tyrolean Alps and the Persian Wild goat. The goats of Cashmere 

 and Thibet furnish extremely fine wool, while the Angora goat (Asia 

 Minor) also furnishes a highly valuable silky hair. In Southern 

 Europe, herds of goats are driven from house to house and milked 

 at the customer's door. 



The ibex is a large wild goat with horns that extend nearly 

 straight up in a scimitar-like curve. Formerly found in the Alps, 

 they are now limited to the Himalaya Mountains, Syria and Abys-
