"They are certainly found in a great many different places," was the reply, "and even in the warmest countries. In one of the missionary settlements in Africa there is a solitary willow that has a story attached to it. It was the only tree in the settlement--think what a place that must have been!--except those the missionary had planted in his own garden, and it would never have existed but for the laziness of its owner. Nothing would have induced any of the natives to take the trouble to plant a tree, and therefore the willow had not been planted. But it happened, a long-time ago, that a native had fetched a log of wood from a distance, to make into a bowl when he should feel in the humor to do so. He threw the log into a pool of water, and soon forgot all about it. Weeks and months passed, and he never felt in the humor to work. But the log of wood set to work of its own accord. It had been cut from a willow, and it took root at the bottom of the pool and began to grow. In the end it became a handsome and flourishing tree."
