mostly done with bow and arrows.

Another story told of his boyhood is that when he was about
twelve he went to look for the ponies with his little brother, whom
he loved much, and took a great deal of pains to teach what he had
already learned. They came to some wild cherry trees full of ripe
fruit, and while they were enjoying it, the brothers were startled
by the growl and sudden rush of a bear. Young Crazy Horse pushed
his brother up into the nearest tree and himself sprang upon the
back of one of the horses, which was frightened and ran some
distance before he could control him. As soon as he could,
however, he turned him about and came back, yelling and swinging
his lariat over his head. The bear at first showed fight but
finally turned and ran. The old man who told me this story added
that young as he was, he had some power, so that even a grizzly did
not care to tackle him. I believe it is a fact that a silver-tip
will dare anything except a bell or a lasso line, so that
accidentally the boy had hit upon the very thing which would drive
him off.

It was usual for Sioux boys of his day to wait in the field
after a buffalo hunt until sundown, when the young calves would
come out in the open, hungrily seeking their mothers. Then these
wild children would enjoy a mimic hunt, and lasso the calves or
drive them into camp. Crazy Horse was found to be a determined
little fellow, and it was settled one day among the larger boys
that they would "stump" him to ride a good-sized bull calf. He
rode the calf, and stayed on its back while it ran bawling over the
hills, followed by the other boys on their ponies, until his
strange mount stood trembling and exhausted.
