Instead of trying to find safety in headlong flight, the Indian stood at bay, with both hands firmly gripping the shaft of his copper-bladed spear, at far too close quarters for employing bow and arrows, while the copper knife in his sash was held in reserve for still closer work. Snarling, growling, displaying its great teeth while clumsily waving enormous paws which bore talons of more than a finger-length, the bear was balanced upon its hindquarters, evidently just ready to lurch forward with striking paws and gnashing teeth. Its enormous weight would prove more than sufficient to end the contest ere it fairly began, while a slight stroke from those taloned paws would both slay and mutilate. No one was better aware of all this than the Indian lad himself, yet he took the initiative, swiftly darting his spear forward, lending to its keen point all the power of both arms and body. A suicidal act it certainly appeared, yet one which could scarcely make his position more perilous. An awful roar burst from bruin as he felt that thrust, the blade sinking deep and biting shrewdly; but then he plunged forward, striking savagely as he dropped. The Indian strove to leap backward an instant after delivering his stroke, but still clung to the spear-shaft. This hampered his action to a certain degree, yet in all probability that stout ashen shaft preserved his life, which that wound would otherwise have forfeited. The stroke but brushed a shoulder, nor did a claw take fair effect, yet the stripling was felled to earth as though smitten by a thunderbolt. All this before the brothers could solve the enigma thus offered them so unexpectedly; but that fall, and the awful rage displayed by the wounded grizzly as he briefly reared erect to grind asunder the spearshaft, decided the white lads, and, temporarily forgetting how dangerously nigh were yonder Aztecan hosts, both Bruno and Waldo opened fire with their Winchester rifles, sending shot after shot in swift succession into the bulky brute, fairly beating him backward under their storm of lead. Victory came right speedily, but its finale was thrilling, if not fatal, the huge beast toppling forward to drop heavily upon the young savage, just as he was recovering sufficiently from shock and surprise to begin a struggle for his footing. Firing another couple of shots while rifle-muzzle almost touched an ear, the brothers quickly turned attention towards the fallen Indian, more than half believing him a corpse, crushed out of shape upon the underlying rocks by that enormous carcass. Fortunately for all concerned, the young Aztec was lying in a natural depression between two firm rocks, and while his extrication proved to be a matter of both time and difficulty, saying nothing of main strength, success finally rewarded the efforts of our young Samaritans.
