With nothing of special importance to do, the whole crowd slept late on the following morning, which was Sunday. Dick Rover was glad to take it easy, but declined to have a physician when that was suggested. "It was only an ordinary blow, and did nothing more than knock me out for a little while," said he. "The swelling on my head is gradually going down, and that little cut on the temple doesn't amount to much." "Those men ought all to be put in prison!" burst out Fred. "Possibly you are right, Fred. But you must remember that you are now in a section of the country where living is rather rough. A new oil town and a new mining camp are pretty much on the same level. You often have to take the law into your own hands and fight your way through the best you can. Later there will be regular law and order, and then matters will run more smoothly." Dick Rover did not mention the matter to the boys, but from that day on he went armed, resolved to take no more chances should any of the oil land swindlers attack him again. Two more days passed, and during that time the boys visited a number of localities in that vicinity, trying to catch sight of Nappy and Slugger, and also Werner. But those three unworthies did not show themselves. "They know we've got it in for them," declared Jack. "They'll keep in hiding until they think this affair has blown over." On the third day Dick Rover felt quite like himself, and he hired an automobile to take him and the boys, as well as Nick Ogilvie, to the Lorimer Spell claim. Somewhat to his surprise, he found Carson Davenport on the land, along with Tate and Jackson and half a dozen other men. More oil-well machinery had been brought up and dumped in a spot near the brook. "What's the meaning of this, Davenport?" questioned Jack's father shortly. "It means that I'm going to work on my own hook, Rover," answered Davenport, and there was a sneer in his voice. "I've got tired of trying to make a deal with you, and I've come to the conclusion that your claim is no good." "I think I understand you perfectly," answered Dick Rover, and looked at the man so sharply that Davenport had to drop his eyes. "You think you have everything your own way, eh?" "Never mind what I think. If you've got any real claim on this property you show the evidences. That little paper that Lorimer Spell wrote out on the battlefield of France doesn't hold water with me. You've got to show me the deeds, and all that sort of thing." "A man can't show papers when he has been robbed of them," went on Jack's father pointedly. "Humph! So that's your latest story, is it, Rover? First when I asked you for the papers you said they were in a safe deposit vault in Wichita Falls." "So they were. But now I have been robbed of them, and you know it." "I know it? Say, Rover, are you going crazy? I don't know any such thing," and now Davenport put on an assumption of anger.
