This I think is rarely more than six or eight 
miles in diameter. If pursued by man, dogs, 
or wolves it is likely to run in great circles, 
keeping within the bounds of home territory. 
Most antelope are not migratory, but in a few 
localities the flocks make a short migration. 
For winter they may travel to a more broken 
locality, one that gives some shelter from the 
wind and contains spaces off which the wind 
sweeps the snow. 
The antelope makes long leaps but not high 
jumps. I watched an antelope that had been 
separated from the flock hurrying to rejoin it. 
In its way was a line of willows along the dry,

he sometimes saw several thousand in a single
