As soon as she had gone, this wee baby turned over, lifted his head, and, seeing the door of the cave ajar, put out his hand. Touching the sides of the cradle, he sprang out like a boy ten years old. Slipping through the doorway, Mercury ran quickly down to the river bank near his home. A river tortoise was in his way. His tiny toes tripped over it and he fell. Vexed to be stopped by such a slow, clumsy creature, Mercury dashed it on a rock and killed it. Then he threw it into the river and watched the fish feed on its flesh. It seemed but a minute before the empty shell drifted to his feet. Mercury picked it up and felt sorry for what he had done.
