"No, I flattened myself on my pony," answered Gracia with a laugh. "He thought you were leading a packhorse."

"Good," chuckled Hooker; "you did fine! Now don't say another word—because they'll notice a woman's voice—and if we don't run into some more of them we'll soon be climbing the pass."

The waning moon came out as they left the wide valley behind them, and then it disappeared again as they rode into the gloomy shadows of the cañon. For an hour or two they plodded slowly upward, passing through narrow defiles and into moonlit spaces, and still they did not mount the summit.

In the east the dawn began to break and they spurred on in almost a panic. The Mexican paisanos count themselves late if they do not take the trail at sun-up—what if they should meet some straggling party before they reached the pass?

Bud jumped Copper Bottom up a series of cat steps; Gracia's roan came scrambling behind; and then, just as the boxed walls ended and they gained a level spot, they suddenly found themselves in the midst of a camp of Mexicans—men, saddles, packs, and rifles, all scattered at their feet.

"Buenos días!" saluted Bud, as the blinking men rose up from their blankets. "Excuse me, amigos, I am in a hurry!"

"A donde va? A donde va?" challenged a bearded man as he sprang up from his brush shelter.

"To the pass, señor," answered Hooker, still politely, but motioning for Gracia to ride on ahead. "Adios!"

"Who is that man?" bellowed the bearded leader, turning furiously upon his followers. "Where is my sentinel? Stop him!"

But it was too late to stop him. Bud laid his quirt across the rump of the roan and spurred forward in a dash for cover. They whisked around the point of a hill as the first scattered shots rang out; and as a frightened sentinel jumped up in their path Bud rode him down. The man dropped his gun to escape the fury of the charge and in a mad clatter they flung themselves at a rock-slide and scrambled to the bench above. The path was rocky, but they pressed forward at a gallop until, as the sun came up, they beheld the summit of the pass.
