The cattle first stolen by the rustlers were not recovered, but it was found that when they seemed they had been spirited off in an airship they had been merely back-tracked and hidden until an opportune time to dispose of them. Del Pinzo's gang was in hiding, waiting for a chance to drive off the main body of steers, when they were surprised by our heroes. Whether Hank Fisher was in with the rustlers was not decided, though suspicions pointed toward him. The outlaws were sentenced to long terms after being captured by the troopers, and their secret meeting place, having been discovered, was destroyed. After these explanations had been made, it was decided not to try to drive the cattle out of the crater until the next day. The night passed without incident, though none of the boy ranchers turned in early. They were too excited, and they wanted to talk over what had happened. The existence of the old crater was not generally known, but Del Pinzo and his rustlers appeared to have the secret of it. They had driven off Bud's cattle, put them into the natural corral and then filled in, with dirt, the only entrance visible from the defile trail leading from Happy Valley. They intended to use the larger opening out of the bowl, to the south, to get the cattle away. But their plans were frustrated. The next day the troopers drove off before them the discomfitted Del Pinzo and his disheartened followers, Yellin' Kid taking the Mexican's elaborate hat to replace the cowboy's with the bullet holes. Lieutenant Wayne said farewell to the boy ranchers, promising to come and see them again, in his real character. The wounded were transported as tenderly as possible out of the main egress from the bowl, it being impractical to use the other. And it was from this larger entrance, after the fence had been torn away, that the cattle were driven, by a long winding trail amid the mountains back to Happy Valley. Only a few were lost by the raid, which was the largest ever perpetrated by the rustlers in that part of the country. "But I guess, now that the troopers have Del Pinzo, and not the local authorities with their flimsy town jails, that this Greaser won't be foot-loose for some time," observed Bud, when, once more, the boy ranchers were back in camp. "I don't want to hear his name again," murmured Dick, nursing his wounded hand. "And to think that Four Eyes was working in our interests when we thought him a spy! That was pretty good!" laughed Nort. "Yes, it all worked out pretty well," spoke Bud. "And do you know what I'd like to do? I'd like Dad to buy that old volcano crater for us. It would be a peach of a place where we could winter a herd of cattle, and have 'em fat for spring selling. I'm going to speak to him about it," he concluded. "Well, you can speak right now, for here he comes, and your mother and sister, too," added Dick, as Mr. Merkel's auto chugged down the trail from Diamond X.
