But that would not satisfy him at all, and one morning he said "Good-by" to all his friends and relatives, and set sail for unknown lands. He set sail, but not on water. He crawled up a tree, and out to the end of one of its branches. There he began spinning a long silken rope, and letting the wind blow it away from the tree. He held fast to one end, and when the wind was quite strong, he let go of the branch and sailed off through the air, carried by his rope balloon, and blown along by the wind.
