back, but it was a moment too late. Kazan was upon him. His long fangs sank deep into Broken Tooth's neck. But the old beaver had thrown himself enough back to make Kazan lose his footing. At the same moment his chisel-like teeth got a firm hold of the loose skin at Kazan's throat. Thus clinched, with Kazan's long teeth buried almost to the beaver's jugular, they plunged down into the deep water of the pond.
Broken Tooth weighed sixty pounds. The instant he struck the water he was in his element, and holding tenaciously to the grip he had obtained on Kazan's neck he sank like a chunk of iron. Kazan was pulled completely under. The water rushed into his mouth, his ears, eyes and nose. He was blinded, and his senses were a roaring tumult. But instead of struggling to free himself he held his breath and buried his teeth deeper. They touched the soft bottom and for a moment floundered in the mud. Then Kazan loosened his hold. He was fighting for his own life now—and not for Broken Tooth's. With all of the strength of his powerful limbs he struggled to break loose—to rise to the surface, to fresh air, to life. He clamped his jaws shut, knowing that to breathe was to die. On land he could have freed himself from Broken Tooth's hold without an effort. But under water the old beaver's grip was more deadly than would have been the fangs of a lynx ashore. There was a sudden swirl of water as a second beaver circled close about the struggling pair. Had he closed in with Broken Tooth, Kazan's struggles would quickly have ceased.
But nature had not foreseen the day when Broken Tooth would be fighting with fang. The old patriarch had no particular reason now for holding Kazan down. He was not vengeful. He did not thirst for blood or death. Finding that he was free, and that this strange enemy that had twice leaped upon him could do him no harm, he loosed his hold. It was not a moment too soon for Kazan. He was struggling weakly when he rose to the surface of the water. Three-quarters drowned, he succeeded in raising his forepaws over a slender branch that projected from the dam. This gave him time to fill his lungs with air, and to cough forth the water that had almost ended his existence. For ten minutes he clung to the branch before he dared attempt the short swim ashore. When he reached the bank he dragged himself up weakly. All the strength was gone from his body. His limbs shook. His jaws hung loose. He was beaten—completely beaten. And a creature without a fang had worsted him. He felt the abasement of it. Drenched and slinking, he went to the windfall, lay down in the sun, and waited for Gray Wolf.
Days followed in which Kazan's desire to destroy his beaver enemies became the consuming passion of his life. Each day the dam became more formidable. Cement work in the water was carried on by the beavers swiftly and safely. The water in the pond rose higher each twenty-four hours, and the pond grew steadily wider. The water had now been turned into the depression that encircled the windfall, and in another week or two, if the beavers continued their work, Kazan's and Gray Wolf's home would be nothing more than a small island in the center of a wide area of submerged swamp.
Kazan hunted only for food now, and not for pleasure. Ceaselessly he watched his opportunity to leap upon incautious members of Broken Tooth's tribe. The third day after the struggle under the water he killed a big beaver that approached too close to the willow thicket. The fifth day two of the young beavers wandered into the flooded depression back of the windfall and Kazan caught them in shallow water and tore them into pieces. After these successful assaults the beavers began to work mostly at night. This was to Kazan's advantage, for he was a night-hunter. On each of two consecutive nights he killed a beaver. Counting the young, he had killed seven when the otter came.
Never had Broken Tooth been placed between two deadlier or more ferocious enemies than the two that now assailed him. On shore Kazan was his master because of his swiftness, keener scent, and fighting trickery. In the water the otter was a still greater menace. He was swifter than the fish that he caught for food. His teeth were like steel needles. He was so sleek and slippery that it would have been impossible for them to hold him with their chisel-like teeth could they have caught him. The otter, like the beaver, possessed no hunger for blood. Yet in all the Northland he was the greatest destroyer of their kind—an even greater destroyer than man. He came and passed like a plague, and it was in the coldest days of winter that greatest destruction came with him. In those days he did not assault the beavers in their snug houses. He did what man could do only with dynamite—made an embrasure through their dam. Swiftly the water would fall, the surface ice would crash down, and the beaver houses would be left out of water. Then followed death for the beavers—starvation and cold. With the protecting water gone from about their houses, the drained pond a chaotic mass of broken ice, and the temperature forty or fifty degrees below zero, they would die within a few hours. For the beaver, with his thick coat of fur, can stand less cold than man. Through all the long winter the water about his home is as necessary to him as fire to a child.
But it was summer now and Broken Tooth and his colony had no very great fear of the otter. It would cost them some labor to repair the damage he did, but there was plenty of food and it was warm. For two days the otter frisked about the dam and the deep water of the pond. Kazan took him for a beaver, and tried vainly to stalk him. The otter regarded Kazan suspiciously and kept well out of his way. Neither knew that the other was an ally. Meanwhile the beavers continued their work with greater caution. The water in the pond had now risen to a point where the engineers had begun the construction of three lodges. On the third day the destructive instinct of the otter began its work. He began to examine the dam, close down to the foundation. It was not long before he found a weak spot to begin work on, and with his sharp teeth and small bullet-like head he commenced his drilling operations. Inch by inch he worked his way through the dam, burrowing and gnawing over and under the timbers, and always through the cement. The round hole he made was fully seven inches in diameter. In six hours he had cut it through the five-foot base of the dam.
A torrent of water began to rush from the pond as if forced out by a hydraulic pump. Kazan and Gray Wolf were hiding in the willows on the south side of the pond when this happened. They heard the roar of the stream tearing through the embrasure and Kazan saw the otter crawl up to the top of the dam and shake himself like a huge water-rat. Within thirty minutes the water in the pond had fallen perceptibly, and the force of the water pouring through the hole was constantly increasing the outlet. In another half hour the foundations of the three lodges, which had been laid in about ten inches of water, stood on mud. Not until Broken Tooth discovered that the water was receding from the houses did he take alarm. He was thrown into a panic, and very soon every beaver in the colony tearing excitedly about the pond. They swam swiftly from shore to shore, paying no attention to the dead-line now. Broken Tooth and the older workmen made for the dam, and with a snarling cry the otter plunged down among them and out like a flash for the creek above the pond. Swiftly the water continued to fall and as it fell the excitement of the beavers increased. They forgot Kazan and Gray Wolf.
Several of the younger members of the colony drew themselves ashore on the windfall side of the pond, and whining softly Kazan was about to slip back through the willows when one of the older beavers waddled up through the deepening mud close on his ambush. In two leaps Kazan was upon him, with Gray Wolf a leap behind him. The short fierce struggle in the mud was seen by the other beavers and they crossed swiftly to the opposite side of the pond. The water had receded to a half of its greatest width before Broken Tooth and his workmen discovered the breach in the wall of the dam. The work of repair was begun at once. For this work sticks and brush of considerable size were necessary, and to reach this material the beavers were compelled to drag their heavy bodies through the ten or fifteen yards of soft mud left by the falling water. Peril of fang no longer kept them back. Instinct told them that they were fighting for their existence—that if the embrasure were not filled up and the water kept in the pond they would very soon be completely exposed to their enemies. It was a day of slaughter for Gray Wolf and Kazan. They killed two more beavers in the mud close to the willows. Then they crossed the creek below the dam and cut off three beavers in the depression behind the windfall. There was no escape for these three. They were torn into pieces. Farther up the creek Kazan caught a young beaver and killed it.
Late in the afternoon the slaughter ended. Broken Tooth and his courageous engineers had at last repaired the breach, and the water in the pond began to rise.
