There were streaks and patches of shining white quartz here and there. Tah-nu-nu had never heard of such a thing as beauty, any more than Ping, but she felt its power as he did not. She arose and stole softly out to look at the marvellous picture made by that ledge in the moonlight. She looked and looked, but she had no Apache word for what she saw. It was all utterly still during many minutes, and then Tah-nu-nu was sure she saw something moving around at the farther border of the ledge. Her first impulse was to go out and see what it was, but her next thought was of her bow and arrows and of Ping.

"Ugh!" said Ping, as she shook his arm, and he sprang to his feet.

"Hist!" she said. "Come! Look!"

He strung his bow and fastened his quiver of arrows to his belt, while she whispered an exclamation. Then he went to where the family packs had been thrown down and brought back a weapon at which Tah-nu-nu nodded approval.

Days before that a careless pony had stepped upon and broken one of the best lances of Kah-go-mish. The blade was as keen as ever, and there were six feet of shaft remaining, below the crosspiece, so that it made a pretty dangerous-looking pike, although it was no longer a lance.

Ping followed Tah-nu-nu, and not a word was uttered until they were out upon the ledge. Some prowling wolf might be there, attracted by the odor of cooked meat and fish, or even some more important animal, for bears also have noses. Ping would not have given a useless alarm for anything. That would have brought upon him sharper ridicule than had the scratch on his ear. He had no idea that any human enemy could be near that lonely camp, and wild animals, he knew, were sure to keep at a distance from camp-fires. That was true, but then Wah-wah-o-be and her friends were not camp-fires, and were not near to any. They were asleep away out on that side of the camp, and it was so safe that it had no sentry, and the eyes of Tah-nu-nu had been of so much the greater value.

She and Ping were stealing out upon the broken ledge, and he had an arrow upon the string, but she had not, as yet.

"Ugh!" he said, as he crouched low and drew his arrow to the head.

Tah-nu-nu uttered a sharp cry. It was the Apache word for "cougar!"

Ping's bowstring twanged, and then he bounded to the right as if he were dodging something. So he was, for the whole camp heard the snarling roar with which a great "mountain lion" came rushing through the air and crashed down a bush close to the children of Kah-go-mish and Wah-wah-o-be.
