It was surprising to Jim and his comrades how quietly Juarez's roan took matters, but there is no relying on a broncho, because he always does the unexpected, and the Captain was so pleased with his behavior that he decided to ride the animal himself.

"Now, that's what I call a well broken hoss," he said. "I ain't so sure of the black so I will let you cruise on him, Jack, being the most active. I don't know what I shall do for Pete, unless I can find him a rocking-horse."

"What are you going to do with the boys?" inquired the mate. "Have 'em walk?"

"They can ride their pack mule," said the Captain grimly.

So Jo, Juarez and Jim were securely fastened on the patient mule, while Tom rode behind the mate upon his own horse, but no longer as master. Then the queer procession started up the trail through the dense fog. The Captain was in the lead, followed by the mate with Tom, then the mule with Pete and the Mexican dwarf guarding the animal and its cargo, while the active Jack Cales was the rear guard. It was exactly twelve o'clock when they weighed anchor and sailed from the harbor or cove in the mountain canyon.

The three boys said little to each other. They did not waste their breath with threats of what they would do to their captors later on, but accepted the situation with true western stoicism. But you may be sure that their minds were active even if their tongues said little.

They were so securely tied that there was no chance for them to make a move as their arms were corded tight to their bodies and their feet were tied under the belly of the mule. Unless they had been experienced riders they would have had a difficult time of it. But it was terribly humiliating, especially under the insolence of the malignant Mexican. But he did not dare do them any actual injury, because the Skipper had given him a warning which he did not dare to disregard. Finally, old Pete put an end to his slurring remarks to the prisoners, so he had to content himself with ugly looks and frequent expectoration wherewith to express his disgust.

Before they reached the foot of the trail, Jack Cales changed with Pete, though the latter demurred at first, at boarding the strange black craft with four legs, but finally consented under the urging of Jack and the warm recommendation of the boys, who had taken somewhat of a fancy to the old sailor, since he had shut up the Mexican in their behalf.

"He won't hurt you, Pop," said Jim, "he is a good horse. Any lady could ride him."

"I ain't no lady," replied the old fellow suspiciously, as he slowly and stiffly mounted, while Jack held his head, that is to say, the horse's head, not Pete's.
