Chapter XX.

HOW CAL STARTED FOR MEXICO.

Wah-wah-o-be and Kah-go-mish had an advantage over Colonel Evans, for they knew what had become of Ping and Tah-nu-nu while his uncertainty about Cal grew darker and darker. He and the cowboys faithfully and warily threaded the part of the chaparral through which they had marched in the earlier hours of that eventful day. The buglers blew regularly, taking care not to get out of hearing of each other, but the firing ceased after it was discovered that a clear bugle-note could be heard farther than could the report of a gun.

As Ping and Tah-nu-nu rode slowly along, they began to comprehend the remarkable proceedings which had so completely puzzled their father, lying under the bushes. Each had one arm connected by a lariat with the arm of a cowboy, but they were not far from one another. They asked no questions and had refused to answer any, but they now and then exchanged a few words in their own tongue when the Chiricahuas were out of hearing.

On went the fruitless search, and at last the two young Apaches were led to a place where two paths ran into one. They knew the spot, for Ping had lost an arrow there. He remembered, too, how he had lost it, and so he said nothing, but Tah-nu-nu had nothing upon her conscience, and she turned to her brother to say, "Ugh! Heap pony!"

"Ah ha! You saw him, did you?" said the sharp-eyed cowboy she was tied to, and he at once shouted to Colonel Evans, who was riding a little ahead of them.

"What is it, Bill?"

"Why, colonel, these two young redskins saw him pass, right here. The gal let it out and the boy doesn't deny it."

The secret was out. Ping himself gave up and was willing to use any English or Spanish words he knew in telling that he had seen "Heap red pony" gallop away by the path which led to the right.

"That's the red mustang," said the colonel, sadly. "Cal's away beyond the spring, long ago. No use to hunt hereaway any more. Call in the boys. We must try the western chaparral. Maybe he will fall in with the cavalry."
