He reached for his gun, which he had laid ready loaded on going to bed; the beast looked well capable of goring or trampling him to death at less than a minute's notice. But even while, half sitting, half lying, he took aim for the creature's eye, a general lowing sounded from farther down the hill, and the bull turned and ran swiftly down the slope. The bewildered Englishman arose and was now able to learn the cause of the lowing. A dozen mounted Indians were in the valley, their horses standing motionless, while two more, approaching from the left and right sides of the hill, were seeking to frighten a small herd of the remarkable-looking animals into the valley. The bull, no doubt the recognised protector of his tribe, whom curiosity had betrayed into a momentary neglect of duty, had heard the bellowings of alarm, and was hastening to the defence of his kindred. But even as he charged wrathfully down the hill, the nearer of the Indians made a motion with his arm, and he fell with a crash that was distinctly audible to the spectator above; while the second Indian, spurring his horse and bawling at the top of his voice, rode straight at the retreating cattle; these, of course, became panic-stricken and ran helter-skelter down towards the spot where the unruffled horsemen were awaiting them with lassoes. From his vantage ground, Hinchcliff watched the proceedings with breathless interest. For a minute or so a whole maze of lassoes showed against the background of the next slope, curling and twirling; then the herd fled, some right, some left; some to rush away out of sight, others to be pulled up in mid-career by the fatal thong that had been deftly thrown over their horns; and so suddenly and sharply, that in most cases they fell to the ground. The Englishman walked quickly towards his particular bull, which lay roaring piteously, but the animal was up again before he could reach him; the Indian had dismounted, slipped a noose over the roarer's head, and untwisted from his forelegs what Hinchcliff at once recognised as a _bolas_--three thongs of equal length, the upper ends joined, the lower loose, and each terminating in a ball of metal or heavy wood. The redskin, whose only garment was a pair of loose-fitting trousers made of deer-skin, looked inquisitively at the stranger and gave him a respectful "good morning" in Spanish; adding to the bull, which was beginning to toss his head and stamp, "Useless, old friend; useless; we have coveted you this many a day," and even while he spoke he vaulted across his horse and started away at a breakneck speed, dragging his captive after him, willy-nilly.
