The boy's heart beat fast as he watched the bold swimmer and the savage reptile. There could be little doubt that the creature weighed a hundred pounds. It is the strongest for its size and the fiercest of all reptiles. Its jaws, though toothless, have cutting edges, a sharp beak, and power to the crushing of bones. Its armour makes it invulnerable to birds and beasts of prey. Like a log it lay on the beach, with its long alligator tail stretched up the bank and its serpentine head and tiny wicked eyes vigilantly watching the shore. Its shell, broad and ancient, was fringed with green moss, and its scaly armpits exposed, were decked with leeches, at which a couple of peetweets pecked with eager interest, apparently to the monster's satisfaction. Its huge limbs and claws were in marked contrast to the small, red eyes. But the latter it was that gave the thrill of unnervement. Sunk down nearly out of sight, the Indian slowly reached the reeds. Here he found bottom, and pausing, he took the rope in one hand, the tomahawk in the other, and dived, and when he reappeared he was within ten yards of the enemy, and in water but four feet deep. With a sudden rush the reptile splashed into the pond and out of sight, avoiding the rope noose. But Quonab clutched deep in the water as it passed, and seized the monster's rugged tail. Then it showed its strength. In a twinkling that mighty tail was swung sidewise, crushing the hand with terrible force against the sharp-edged points of the back armour. It took all the Indian's grit to hold on to that knife-edged war club. He dropped his tomahawk, then with his other hand swung the rope to catch the turtle's head, but it lurched so quickly that the rope missed again, slipped over the shell, and, as they struggled, encircled one huge paw. The Indian jerked it tight, and they were bound together. But now his only weapon was down at the bottom and the water all muddied. He could not see, but plunged to grope for the tomahawk. The snapper gave a great lurch to escape, releasing the injured hand, but jerking the man off his legs. Then, finding itself held by a forepaw, it turned with gaping, hissing jaws, and sprang on the foe that struggled in bottom of the water. The snapper has the bulldog habit to seize and hold till the piece tears out. In the muddy water it had to seize in the dark, and fending first the left arm of its foe, fastened on with fierce beak and desperate strength. At this moment Quonab recovered his tomahawk; rising into the air he dragged up the hanging snapper, and swung the weapon with all the force of his free arm. The blow sank through the monster's shell, deep into its back, without any visible effect, except to rob the Indian of his weapon as he could not draw it out. Then Rolf rushed into the water to help. But Quonab gasped, “No, no, go back--I'm alone.”
