The book of antelopes, vol. 4…
(1899)
“ With all his wits about him, the lordly bull, active and powerful, may now and then be detected browsing at grey dawn upon some rugged hill summit, or ranging some grassy slope, either alone, or escorted by a small troop of skittish dames, all seeming alike his sentinels; but taking the note of alarm from the slightest noise, he stamps his brave foot upon the ground, tosses his spiral frontlet to the blue sky, and once fairly in motion, never stops to look behind until he has gained the threshold of his sanctuary. ”
