"Never you mind," was the enigmatical answer, given with a shake of the head, "but I have 'em all right. However, that's another matter. What we have to do now is to get ready to meet any of these sheep men if they come up and try to cross the creek."

"You reckon he's gone back to his gang to tell 'em to get ready to come here?" asked Snake.

"Shouldn't wonder," admitted Billee. "But it'll be some time before they can bring up the woollies."

"Sheep travel fast, they eat fast and they ruin water and pastures faster'n Sam Hill!" exclaimed Yellin' Kid, and this was true. If you have ever watched a flock of sheep feeding you would know this. They eat as though they feared some one was going to take all the grass away on a moment's notice.

"Well, he's ridin' fast," observed Snake, as, shading his eyes with his hat, he gazed in the direction taken by the lone horseman. The fellow was almost out of sight now, and soon was lost to view.

Danger now seemed more imminent than it had been, and, as behooved efficient cowboys, our friends at once began going over the situation and making sure that they had done all that was possible to fortify their position.

Of course, while I have referred to the shack hurriedly erected as a "fort," it was nothing of the sort. There were no heavy walls, and of course no artillery, though the boys wished they did have a machine gun. But, on the other hand, no artillery would be brought up against them, so this evened matters up. If it came to a fight there would be only revolvers used on both sides at first, though later rifles might come into play. However, not even the most rabid of the cowboys from Diamond X really wanted a bloody fight. They would much rather the sheep men kept away, leaving the rightful owners of the land in possession.

But, as Billee had said, the stealing of Mr. Merkel's papers seemed to indicate some deep-laid plot to cheat him of his land that was so valuable.

"We're in as good shape as we can be, until it comes to a showdown and a fight," remarked Billee, when the noon-day meal was served, after they had gone carefully over the defense. "Did you get your dad?" he asked Bud.

"Yes, I had him on the wire," answered the son of the owner of Diamond X. "Nothing new has developed back home, and I told him about this fellow. He thinks, as we do, that he was a spy."
