"Well, we've seen the last of him for a while."

"Aren't you going to try to catch him?" asked Nat, as he watched the horse dash across the meadow-like hollow, and then vanish in the belt of dark wood on the hillside beyond.

"No good," said Cal decisively, "wouldn't be able to do a thing with him for days. That loco weed is bad stuff. If I'd ever noticed it growing around here you can bet that Bismuth, or whatever that Dutchman calls him, wouldn't have left the camp."

Herr Muller, rubbing a grievous bump he had received when the ungrateful equine turned upon the hand that fed him, now came up and joined the party. He made such a grievous moan over the loss of his horse that Nat's heart was melted. He promised finally that they would stay in the vicinity the next day, and if Bismark had not appeared that they would make a short search in the mountains for him.

This was strongly against Cal's advice, but he, too, finally gave in. The Westerner knew better even than the boys with what a desperate gang they were at odds, and he did not favor anything that delayed their getting out of that part of the country as quick as possible.

"My mine is only a day or so's run from here," he said to Nat, "and if once we reached there we could stand these fellows off till help might be summoned from some place below, and we could have Morello's gang all arrested."

"That would be a great idea," agreed Nat, "do you think it could be done?"

"Don't see why not," rejoined Cal, "but you'll see better when you get a look at the place. It's a regular natural fortress, that's what it is. My plan would be to hold 'em there while one of us rides off to Laredo or Big Oak Flat for the sheriff and his men."

"We'll talk some more about that," agreed Nat, to whom the idea appealed immensely. In fact, he felt that there was little chance of their really enjoying their trip till they were sure that Col. Morello's gang was disposed of. Somehow Nat had a feeling that they were not through with the rascals yet. In which surmise, as we shall see, he was right.

Supper that night was a merry meal, and after it had been disposed of, the waterproof tent which the boys had brought along was set up for the first time. With its sod cloth and spotless greenish-gray coloring, it made an inviting looking little habitation, more especially when the folding cots were erected within. But Herr Muller was in a despondent mood. He ate his supper in silence and sat melancholy and moody afterward about the roaring camp fire.
