"Bugles?" said Colonel Evans.
"Why, yes," said the captain, "if Cal is tangled in the chaparral he must have something to guide him. I must push on, along the boundary line, to see what luck I can have with the Mescaleros. Colonel Romero and his men will follow their direct trail, and so they won't find them; but we both make it safer for you. Patrol back, blowing all sorts of noise, and Cal's pretty sure to ride right up to one bugle or another. Scatter 'em wide."
"Thank you. Thank you, captain," said the colonel. "Sam, get all the bugles you can. Give a horse for a bugle. Give anything!"
The captain at once rode into Mexico for a talk with Colonel Romero. There was, indeed, an over-supply of musical instruments in that command, and its gallant colonel sympathized impressively with the feelings of Cal's father and friends. So did two militiamen who were happy enough to own unnecessary bugles. Sam Herrick did not give a horse for either, but one battered, crooked tube of sheet brass brought enough money to replace it with a new one at least half silver.
Captain Moore hardly needed to explain so simple a plan. He had tried it twice, he said, for stray men of his own, and in each case they had ridden safely in. Neither he nor Colonel Evans guessed that Cal had already ridden away beyond the stretch of chaparral in which they proposed to toot for him.
Chapter XVII.
HOW PING AND TAH-NU-NU GOT TO THE SPRING.
Colonel Romero and his gay lancers and his picturesque ranchero militia rode away along the well-marked trail so carefully left for them by the Apaches. It led manifestly into their own republic, and there seemed to be no danger whatever of their losing it. They had two bugles less than when they entered the chaparral, but they made noise enough to notify any red men lurking in the bushes ahead of them that they were coming. The one special precaution which they continually took was against possible ambuscades. They were determined not to be taken by surprise, and their wary scouts routed out a considerable number of jackass rabbits and sage-hens. Beyond these they met with no excitement whatever until they came to the barren gravel patch, beyond which the Apache trail did not go.
