"There is a cave in the mountain on the other side which I defy anyone to find," said Don Jose. "If there were a war my sons should fight, but I need them now."

While the horses were saddling, Roldan and Adan consulted together. At the end of a few moments the former went up to Don Jose.

"I think it would be wiser to separate," he said. "Adan and I will go one way, your sons another. That will put them off the track; and the cave, Carlos says, is not very large."

"As you like," said Don Jose, who was perturbed and busy. "A vaquero will go with you for a distance and advise you."

The truth was, Roldan fancied lying inert in a cave for several days as little as he fancied the somnolent life of a barrack, and Adan, who had a secret preference for the cave, was too loyal to oppose him.

In ten minutes the horses were ready, affectionate good-byes said, and Roldan and Adan, followed by many good wishes, and prayers to return, started southeastward through a dense canon.

The vaquero guided the boys rapidly through the canon. The almost perpendicular walls, black with a dense growth of brush and scrub trees, towered so high above them that the atmosphere was damp and the long strip of sky was like a pale-blue banner. The trail was well worn, and there was nothing to impede their progress. The mustangs responded to the lifted bridle and ran at breakneck speed. They emerged at the end of half an hour. It was an abrupt sally, and the great level plain before them seemed a blaze of sunlight.

"Bueno," said the vaquero, halting. "Ride straight ahead. Keep to the trail. At night you will come to a river. Before you reach it all trace of you will be lost, because between now and there are many side trails, and as the ground is so hard they cannot tell which you take. Cross the river and take the trail to the left. That will bring you to the Mission—about twenty miles farther—where the good padres will let you rest and give you fresh horses. The senor, meanwhile, will throw the officers off the scent. But if you are wise, you will make for the Sierras and hide there. Adios, senor, adios, senor;" and he wheeled about and disappeared into the darkness of the canon.
