Summer arrived, and with it the moulting season when the wild water-fowl shed their feathers, with which the Indians fledge their arrows. Near Nopatsis's lodge there was a great lake, to which these birds resorted in large numbers, and to this place the brothers went to collect feathers with which to plume their darts. They built a raft to enable them to reach an island in the middle of the lake, making it of logs bound securely with buffalo-hide. Embarking, they sailed to the little island, along the shores of which they walked, looking for suitable feathers. They parted in the quest, and after some time Akaiyan, who had wandered far along the strand, suddenly looked up to see his brother on the raft sailing toward the mainland. He called loudly to him to return, but Nopatsis replied that he deserved to perish there because of the brutal manner in which he had treated his sister-in-law. Akaiyan solemnly swore that he had not injured her in any way, but Nopatsis only jeered at him, and rowed away. Soon he was lost to sight, and Akaiyan sat down and wept bitterly. He prayed earnestly to the nature spirits and to the sun and moon, after which he felt greatly uplifted. Then he improvised a shelter of branches, and made a bed of feathers of the most comfortable description. He lived well on the ducks and geese which frequented the island, and made a warm robe against the winter season from their skins. He was careful also to preserve many of the tame birds for his winter food. One day he encountered the lodge of a beaver, and while he looked at it curiously he became aware of the presence of a little beaver. "My father desires that you will enter his dwelling," said the animal. So Akaiyan accepted the invitation {186} and entered the lodge, where the Great Beaver, attended by his wife and family, received him. He was, indeed, the chief of all the beavers, and white with the snows of countless winters. Akaiyan told the Beaver how cruelly he had been treated, and the wise animal condoled with him, and invited him to spend the winter in his lodge, when he would learn many wonderful and useful things. Akaiyan gratefully accepted the invitation, and when the beavers closed up their lodge for the winter he remained with them. They kept him warm by placing their thick, soft tails on his body, and taught him the secret of the healing art, the use of tobacco, and various ceremonial dances, songs, and prayers belonging to the great mystery of 'medicine.' The summer returned, and on parting the Beaver asked Akaiyan to choose a gift. He chose the Beaver's youngest child, with whom he had contracted a strong friendship; but the father prized his little one greatly, and would not at first permit him to go. At length, however, Great Beaver gave way to Akaiyan's entreaties and allowed him to take Little Beaver with him, counselling him to construct a sacred Beaver Bundle when he arrived at his native village.
