He was not afraid to go out alone, although his grandfather had always gone with him. It was only a few steps and he thought nothing could harm him, but something seemed to hold him back and fill him with a sense of danger. Then he happened to glance up and, close to the opening in the ice, he saw a large gray animal crouched, watching the hole intently.

The stranger was two or three times the size of Shaggycoat, as large as any beaver he had ever seen, but he was not a beaver. His fore paws were too long and powerful, his head with tufted ears too flat, and his eyes were too cruel and hungry. The longer Shaggycoat looked at the fierce animal above him on the ice, the greater grew his fear, until he fled at a headlong pace to the overhanging bank, where his grandfather was sleeping. His precipitate flight into the burrow awoke the old beaver who slept lightly and was always watchful.

When Shaggycoat related his adventure, the old beaver looked troubled and combed his head thoughtfully with the claws upon his hind leg. After dusk had fallen and the stars appeared, he carefully reconnoitred, leaving Shaggycoat in the burrow. After half an hour's time, he returned and his manner was anxious.

He told Shaggycoat that they must not use the opening in the ice any more or go upon the land, for a lynx had found their hiding-place and would watch by their front door until he dined upon beaver meat. They must start that very night and go farther up the river and find a new opening, and even then they must be cautious. This was sorrowful news for them both and the younger beaver remonstrated against leaving their fine store of bark, but he got a sharp nip in his ear and was told to keep his advice until it was asked for. So, after making a hearty supper, they went sorrowfully upon their way to find a new open spot in the river where the lynx would not be watching for them.

They went only about a mile that night, but found several open spots for the ice was getting ready to break up. At last, they found a place that suited them and dragged themselves up under a sheltering bank, near a rapid, that afforded them a chance to go in search of food. Then the old beaver slept long and sound, leaving Shaggycoat upon guard with orders to wake him if anything uncommon appeared.

The young beaver did not like these silent vigils and the hours seemed very long to him, but he did as he was told. He thought his grandfather never would wake, but at last he did, late in the afternoon, but they did not go ashore for bark—it was too dangerous, the older beaver said—so they had a slim supper of frozen lily pads. But this was not enough for the hungry stomach of Shaggycoat who gnawed away at some tree roots that pierced the bank where they were hiding. It was not as good as the fresh bark of the birch, but it filled him up and made him feel better.

If Shaggycoat had been older and wiser, he would have been alarmed at the old beaver's symptoms, but he was young and thoughtless, and knew not of age, or the signs of failing life.

At last the spring freshet came and the ice in the river broke up. Then they had to look for a spot where the bank was very high so they would not be drowned out. It was a long and arduous search to find the right spot, but at last it was found just in time, for the old beaver's strength was nearly spent. But every day that the snow melted and the ice went out of the river, food for the beavers grew more plentiful and the sunshine and hope of spring made them glad.

Shaggycoat was now left to himself, to swim in the river and feed upon the bark of saplings along the shore. The old beaver was too tired with their long journey to venture out of the burrow they had chosen. He gave Shaggycoat much good advice, and among other things told him to always keep close to the water where he was comparatively safe, while upon land, he was the easy prey of all his natural enemies. The peculiar angle of his hind legs made it impossible for him, or any other beaver, to travel much on shore, but, while in the water they were his safeguard.

These were delightful days for the two-year-old. The water was getting warm and the mere act of swimming filled him with delight. Besides, it seemed like a very wonderful world in which he lived. He had come so far and seen so many strange things. He wondered if there were other rivers and if they were all as long as this one.
