"Very neatly."

"Sure," from Billie. "It was a short stop."

"I perceive that you are an American. I am also a fan."

"What!" from the three Americans.

"True. I am even worse. I formerly shot the pill in one of the bush leagues. I aspired to a place in the box of one of the major league clubs, but instead I joined the Madero revolution. I had all the sport I wanted and finding my brother in this forsaken land, I joined him as a public entertainer. Shall we give you a sample of our performance?"

"Not now," from Donald. "Let's go and round up this bunch of revolutionists first."

"But why?" queried the mountebank. "To-morrow they may be the government."

The boys looked at each other with an expression that said as plainly as words: "True! We never thought of that."

"Now, I have a better plan," continued the mountebank. "Let's go and entertain the revolutionists. Let's be neutral."

"I'm afraid we are already belligerents," laughed Adrian. "We have had one brush with them."

The mountebank heaved a sigh.

"Of course, if you have declared war, we shall have to fight to a finish, unless," with a grin, "we can intrench."

"It is they who are intrenched," explained Billie. "They are at the bottom of the old mine, although I don't know how they got there."

"So," laughed the mountebank. "Suppose we go and find out."

Arrived at the shaft house, for that is what the gable-roofed building was, the boys and their new-found friend approached and listened to the sound of voices which still arose to the top of the shaft.

Evidently considering themselves free and safe, the bandits were preparing their evening meal, for it was now well on toward sunset. They were singing and joking as though they had not just lost half or two-thirds their number.

From a few remarks made now and then, it appeared that they proposed on the following day to recruit the band up to its former strength.

"That is the thing we must prevent," declared Donald.

"A very easy thing," said the mountebank, "if we had enough provisions to remain here for twenty-four hours, or more."

"How so?" asked Billie.

"Why, they will doubtless send out two or three to do the recruiting. We can capture them as they leave the ruins."

Billie glanced at the man from under his broad-rimmed sombrero as he asked: "How did you know they came out through the ruins?"

The mountebank smiled.

"Now, don't go to mistrusting me, young fellow, for I'm on the level. But I've been in this place before, and I know that the only way to where your friends down there are camping is through the ruins."

"Have you ever been down there?"

"Yes. They are only about sixty feet below the ground, in a chamber which was originally a gallery in the mine. The shaft over which this house is built is over two hundred feet deep."

"I'd like to explore it," remarked Adrian.

"Do you think you have the nerve?" and the stranger bent upon him a penetrating gaze.

Billie laughed softly.

"Say, stranger," he finally said. "I guess you never heard of the Broncho Rider Boys. We've got the nerve to do anything that any other human being dare do."

"Then we'll get rid of these bandits in short notice," declared the mountebank emphatically. "You are just the chaps I have been looking for."

He leaned over the mouth of the shaft and gave a shrill whistle.

In an instant all was silent below.

Half a minute later he repeated the whistle thrice.

There was a clatter below of arms and accoutrements.

"Over behind those big cactus with you, quick," was the next command. "If you insist on fighting these men later, you can.

Now let's get rid of them."

For just a moment the boys hesitated, but there was something in the man's manner that seemed to force obedience and they obeyed.

They were not a moment too soon, for they had no more than secreted themselves than the back wall of the ruin flew open and the men rode out. Of those who had been at the mouth of the shaft only a few moments before, only the mountebank with his ape was in sight.

"What is it?" asked one of the band, riding up to him.

"Guard the track at the summit. Let no train pa.s.s, even if you have to tear up the track."

"By whose order?"

The mountebank made a mysterious sign with his left hand.

"_Bueno!_" from the horseman. "Close up the doors and care for the wounded," and putting spurs to his horse, he led the bandits from the basin.

As soon as they were out of sight, the mountebank summoned the boys to the shaft house by a wave of his hand.

"Now," he said, "you'll have a chance to test your nerve, and we must work rapidly to get where we wish to go before dark."

He took from a crude knapsack which he wore upon his shoulders a coil of cord about half the size of a lead pencil, but evidently of much strength. Then seizing the ape, he fastened one end of the cord to the belt about the animal's body, and despite its unwillingness to be thus treated began to lower it into the shaft.

Totally unable to account for his actions, the boys stood speechless, watching the operations.

After some minutes, the cord slackened.

"He's reached the bottom," was the information vouchsafed. Then a moment later: "Help me to pull him up, one of you."
