The Cave Twins in Bloomington, MN

One bright morning of early spring, long ages ago, the sun peered through the trees on the edge of a vast forest, and sent a shaft of yellow sunlight right into the mouth of a great, dark cave. In front of the cave a bright fire was burning, and on a rock beside it sat an old woman. In her lap was a piece of birch-bark, and on the bark was a heap of acorns. She was roasting them in the ashes and eating them. At her right hand, within easy reach, there was a pile of broken sticks and tree-branches, and every now and then the old woman put on fresh wood and stirred the coals to keep the fire bright.
