One summer long ago, when the Blackfeet Indians roamed freely over the Canadian plains, the son of one of the Chiefs decided to go off alone to seek adventure. He wanted to be a great man like his father, and he thought he could never become great if he always stayed at home. He said to his father, "I am going away far to the West, beyond the mountains. I have heard that our Indian enemies who live there have many fine horses. I will bring some of their horses back to you." His father loved his son well, for he was his only child. He knew that it would be a very dangerous journey, and he tried to persuade his son not to go. But the boy said, "Have no fear for me. If I do not come back before the frost is on the prairies, do not be worried about me. But if I do not come before the snow lies deep on the plains, then you will know that I have gone forever and that I shall never come back." His father knew that only by attempting dangerous deeds and doing hard tasks could his son become great. And although he was loath to see him go, he said good-bye and wished him good luck.
