At the time when our story begins, Shaggycoat was a two-year-old beaver, fleeing with his grandfather from he knew not what. They had been so happy in the woodland lake, which was their home before the terrible intrusion, that the whole matter seemed more like a hideous dream than a reality.

When Shaggycoat thought of the old days and his family, he could remember warm summer afternoons upon clean sand banks, where he and his brothers and sisters frolicked together. Then there were such delightful swims in the deep lake, where they played water-tag, and all sorts of games, diving and plunging and swimming straight away, not to mention deep plunges to the bottom of the lake where they vied with one another in staying down. Then when they were hungry, the bulbs of the lily and a cluster of wild hops made a dinner that would make a beaver's mouth water; with perhaps some spicy bark added as a relish.

Then came the cold and the pond was covered with ice. They could still see the sun by day and the stars by night, but they could not come to the surface to breathe as they had done before. There were a great many air holes, and places under the ice where the water did not reach it, but for breathing space they had to depend largely upon the queer conical houses in which they lived and their burrows along the bank.

There was still another way to breathe that I had nearly forgotten. A beaver or any of these little Water Folks can come up to the surface and breathe against the ice. A big flat bubble is at once formed and as it strikes the ice it is purified and then the beaver breathes it in again and it is almost as fresh as though it came from the upper air. This he can do three or four times before having to find an air hole or going into one of the houses or burrows.

The beavers were very snug under the ice which kept away the wind and cold, and also their worst enemy, man.

The breath of the family made the houses warm, and as the walls were frozen solid, and were two or three feet thick, they were very hard to break into.

A store of wood had been laid up from which the bark was stripped for food as fast as it was needed, so that Beaver City had been very snug and comfortable, before the trouble came.

Then when they were sleeping through the short winter days, and prowling about the lake in the night in search of fresh twigs or sticks that had been frozen into the ice, the trouble began.

First there came the sound of pounding and soon there were holes in the ice near their supply of wood. Then occasionally a beaver who was hungry and had gone for breakfast was missed from the family or lodge where he lived. At first they thought he had gone for a swim on the lake and would soon come back, but when several had gone out to the winter's store and had not returned, the truth dawned upon some of the older and wiser beavers. Their forest lake had been invaded by some enemy, probably man, and one by one the colony was being slaughtered.

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.

When daylight came, they had covered five good English miles up the river, and were nearly eight miles from their dam and the beautiful woodland lake that had been their home.

Then the old beaver began looking for some burrow or overhanging bank where they might hide during the day and get some sleep, of which they were in great need. Finally they found a suitable place where the bank had shelved in, leaving a natural den, high and dry above the water. Here they rested and passed the day, getting nothing better to eat than a few frozen lily stems and some dead bark from a log that had been frozen into the ice. The dry lifeless bark was not much like the tender juicy bark that they were used to, but it helped a little to still the gnawings of hunger, and in this retreat they soon fell asleep and slept nearly the whole of the day.

But the older beaver was always watchful, sleeping with one eye open, as you might say, and waking very easily.

Once, when he was awakened by a sense of danger, he saw a large otter swim leisurely by their hiding-place and his heart beat hard and fast until he was out of sight, for he knew that if the otter discovered them, he would at once attack them and the battle would probably end in his favor.

Shaggycoat would be of little help in a real fight for life and the old beaver was far past his prime, his teeth being dull and broken. When the otter was out of sight, the watchman lay down and resumed his nap.

When Shaggycoat awoke, he knew it was evening for he could plainly see the stars shining through the ice.

His legs were cramped and stiff and there was a gnawing sensation in the region of his stomach, but there was nothing in sight to eat. His grandfather informed him in beaver language that there were weary miles to cover before they could rest again.

As soon as it was fairly dark, they came out from under the overhanging bank that had shielded them so nicely during the day and resumed their journey, swimming like two ocean liners, on and on. Their track was not as straight as that of the boats would have been, for they dodged in and out, going where the darker ice and projecting banks gave them cover, and stopping when they scented danger.

When they had gone about a mile, they found a spot where the river had set back over the bank, freezing in some alder bushes. Upon the stems of these they made a scant meal and went on feeling a bit better. This night seemed longer and wearier to Shaggycoat than the first had. He was not so fresh and the first excitement was over, but the old beaver would not let him rest as he knew their only safety lay in putting a long distance between them and their destroyers.

They were not so fortunate in finding a hiding-place as they had been the day before, but they finally took refuge in a deserted otter's burrow, which made them a very good nest, although it was possible that some wandering otter might happen in, and dispossess them.

When night again came round, they made a light supper on frozen lily stems and pushed on. They covered less distance that night than they had done before, for both were feeling the strain of the long flight, and so they rested frequently and took more time to hunt for food.

About daybreak of this third night of their journey, they found an open place in the ice where the stream was rapid and went ashore; here they soon satisfied their hunger upon the bark of the poplar and birch.

When they had made a good meal, the prudent old beaver, assisted by Shaggycoat, felled several small poplars and cutting them in pieces about three feet long dragged them under the ice to a protected bank and hid them against the time of need, for he had decided to spend a few days where they were, getting the rest and sleep which they both needed.
