 Prong-horn. '(A-) 



Unlike those of other Antelopes, the horns of the 



Prong -horn are deciduous. 

 The core, however, is not 

 exposed, but is protected by 

 a growth of stiff hairs. 



The Mountain Goat is ex- 

 tremely rare, though some- 

 times found on the higher 

 slopes of the Rocky Mount- 

 ains. It has small, jet black, 

 ringed horns, and long white 

 hair. 



The Mountain Sheep, 

 found wild on the Rocky 

 Mountain slopes, has a con- 

 vex forehead, horns directed backward, then spirally for- 

 ward, and two kinds of hair, one being crimped. It feeds 

 on grassy knolls surrounded 

 by craggy rocks, to which it 

 retreats when attacked by 

 wolves Its horns sometimes 

 grow so long and curve so far 

 downward and forward, that it 

 can not graze on level ground. 

 It was formerly supposed to 

 inhabit only the higher and 

 more inaccessible cliffs ; but 

 more recent explorations have 

 found it at home in the Bad Lands about the sources of 

 the Missouri and Yellowstone rivers.
