PRONG-HORNED ANTELOPE 
range. These antelope were, in fact, very much tamer than any others I 
afterwards saw in the main range in the Big Horns, where they were little 
hunted yet were constantly on the watch. I have several times noticed this 
disposition amongst wild animals; for, where they are very abundant 
and on some home range which they have no intention of leaving, they 
will often permit hunters of experience (that is to say, men who do not 
follow and chase the game after having fired a single shot) to stay almost 
in their midst and take toll of them; whilst in other places where they 
are only rarely disturbed, but are nevertheless not permanent dwellers, 
they seem to be always on the qui vive and full of suspicion. So, too, the 
wildness or tameness of certain animals, especially antelopes, seems to 
be affected by weather as well as the movements of men who pursue them. 
I have toiled for hours, and often for days in the sun in Africa, trying to 
get near wild antelopes and, after repeated failures, have, during the 
same day ridden my horse, or walked past troops of the same antelope 
within 100 yards, when I had no desire to shoot one. 
In the mountains it is common to see one, two or three adult males 
together, always standing on the ridge and using their telescopic eyes. 
I have now seen a good many wild animals in their homes, and have not 
yet discovered one that approaches the American prong -buck in powers 
of vision. Even the sharp eyed mountain sheep is its inferior and one mem- 
ber of a band is always on the look out. When a prong -horn stands upon 
a ridge he seems to see even the things that lie still, as well as the things 
which move, which few animals do; and if two men are hunting together 
almost the only chance of a shot is for one to remain in full view of the 
game, and allow the other to crawl away and make the stalk. Even this is 
seldom successful, for by the time the stalker has make his circuit the 
antelope has got tired of watching the man in the valley and has retired 
to the next ridge. 
As already noted, these antelope are only migratory when forced to move 
by severe conditions. The prong-buck in Jackson’s Hole go south 150 miles 
to the Red Desert. Those of the main range of the Rockies go first towards 
the foothills and then to the open prairies. Formerly vast numbers of 
antelope collected about Colorado Springs in the winter, and, when the 
Union Pacific was first opened, enormous numbers were seen in every 
sheltered valley between Cheyenne and Denver. 
The old range of the prong -buck covered an area of two million square 
miles, whilst the present range is about half that size. The reduction
