There is but one thing to do at such a time and that is to take safety in flight, for the beaver does not consider that he can match his cunning against that of man.
While the beavers were still considering whether to go at once or wait another day, there were sounds of heavy blows upon the tops of their houses and then there was a loud explosion and the water began to fall. Then they fled in every direction, some taking refuge in the burrows that they had dug under the banks all along the lake for such an emergency, while others sought to leave the lake altogether; some going up stream and some down. But the destruction of Beaver City had been planned very carefully by their cunning enemy, man, and most of them perished while leaving the lake.
When the men who were watching on the ice above saw a beaver swimming in the water under them, they would follow upon the ice, going just where the beaver went. The beaver would stay near the bottom of the lake as long as he could hold his breath, but finally he would have to come to the surface for air when the trapper would strike a hard blow upon the ice, stunning him, or perhaps killing him outright. Then he would cut a hole in the ice and fish out his unfortunate victim.
It was from such perils as these, although they were not fully understood by the beavers, that Shaggycoat and his grandfather fled the second night of this reign of terror. They would gladly have gone in a larger company, with Shaggycoat's brothers and sisters and with his father and mother, but all the rest of their immediate family were missing and they never saw them again.
They went in the inky night, before the moon had risen. Silently, like dark shadows, they glided along the bottom of the lake, which was still about half full of water, for the white man's thunder had not been able to entirely destroy the beaver's strong dam.
Shaggycoat's grandfather, being very old, and wise according to his years, took the lead, and the younger beaver followed, keeping close to the tail of his guide. They swam near the bottom and were careful to avoid the bright light of the great fires that men had built upon the ice in many places to prevent their escape.
By the time the moon had risen they were near the upper end of the lake. They at once took refuge in an old burrow that the trappers had overlooked and lay still until the moon went under a cloud when they came out and crept along the bank, still going under the ice. When the moon appeared again they hid under the roots of a tree that made a sort of natural burrow. There they lay for all the world like the ends of two black logs, until a friendly cloud again obscured the moon when they pushed on. Once the trappers came very near to them when they were hiding behind some stones, waiting for a friendly cloud, and Shaggycoat was about to dash away and betray their whereabouts, when his grandfather nipped him severely in the shoulder which kept him still, and alone saved his fine glossy coat.
They were now getting well up into the river that had supplied their lake, and it was not so easy to find breathing places as it had been in the lake where the water was low. But they could usually find some crack or crevice or some point where there were a few inches between the water and the ice and where they could fill their lungs before they journeyed on.
They had come so far and so fast that poor Shaggycoat's legs ached with the ceaseless motion, but the older beaver gave him no rest, and led him on and on, swimming with easy, steady strokes. Although his own legs were weary and a bit rheumatic, he valued his life more than he did his legs and so set his teeth and breasted the current bravely. They both held their fore paws close up under them and used their hind legs entirely for propelling themselves, so these had to do double duty, plying away like the screw wheel on a great steamer.
When Shaggycoat remonstrated against going any farther, saying in beaver language that his legs were ready to drop off, his senior reminded him that his skin would drop off if they stopped, and, with a new wild terror tugging at his heart, he fled on.
