As the two youths looked they heard a shot and saw a movement among the buffaloes. Another shot followed and then a half dozen. The portion of the herd near by seemed suddenly to contract and to roll in upon itself. The waiting wolves disappeared in the woods, and snorts of terror arose from the herd. "There they are! I see them!" exclaimed Paul. "It is the Spaniards, sure enough!" Five or six men in the Spanish military attire burst from the forest, not more than a hundred yards away, and continued to fire as fast as they could into the herd. "How foolish!" exclaimed Henry. "Either they are wasting their shots or if they don't waste them they are killing far more buffaloes than they can use!" The boys withdrew into a thicket, as they did not wish to be seen by the Spaniards, and watched closely. The soldiers continued to reload and fire and uttered shouts of joy whenever a buffalo fell. Transported by excitement they scattered, and one man ran down near Paul and Henry, detaching himself unconsciously from the rest of his comrades. This Spaniard was young and athletic, and he fired at a huge bull. Had he been an experienced hunter, he would have known better, as the bull was too big and tough to eat, and he was also one of the savage guardians of the herd. Moreover, the Spaniards were armed mostly with muskets, a weapon far inferior to the Kentucky rifle. This great bull stung in the flank, but stung only, uttered a roar of pain, and, sharp horns down, charged directly upon the young Spaniard. He was a terrifying sight as he tore up the grass of the prairie, his red eyes flaming. The Spaniard, appalled, dropped his musket and ran for the woods, the great beast thundering at his heels, and his hot breath, in fancy at least, upon his back. Both Paul and Henry at that instant recognized him. It was one of the unfortunate sentinels. Luiz. "I'll save him," said Henry, "but keep back, Paul! Don't let him see you!" The Spaniard was about to reach the edge of the wood, but another jump would bring the raging buffalo upon him. His foot caught among some roots and with a despairing cry he fell upon his face. But as he struck the ground there was a sharp, lashing report, far different from the dull boom of a musket, and the great animal suddenly ploughed forward on his head. So violent was his plunge, as he was stricken in mid-charge, that his neck was broken, and, after his crashing fall, he lay quite still.
