"So Little Chief made his home in the rock-slide high up on the mountain
and was happy, for it was just as he thought it would be--no one
thought of looking in that bare place for him. For food he ate the pea
vines and grasses and other green things that grew just at the edge of
the rock-slide and was perfectly happy. One day he decided he would take

took home to add to his bed. Then he took home some more that was green,
and this spoiled just as the other had done.

"Little Chief was puzzling over this as he squatted on a rock taking a
