Del Pinzo and others tried more of their tricks and in the succeeding volumes of the series is related about the water fight, the battle with more cattle rustlers, how the Yaqui Indians were trailed, and how the sheep herders were overcome. "The Boy Ranchers on Roaring River; or Diamond X and the Chinese Smugglers" is the title of the book immediately preceding the present volume, and in that Bud, Dick and Nort had some narrow escapes from unscrupulous men. Incidentally they helped the United States government bring to justice a large Chinese smuggling band.

Things on Diamond X had somewhat quieted down after the strenuous days with Delton and the others, and Mr. Merkel had gone off on a business trip, the import of which was little known to the boys. He had returned, as has been related, in time to see Bud leap from the fence to the back of a galloping horse in preparation for rodeo stunts.

Then Billee Dobb had made his startling announcement about the ominous character of the new ranch purchased by the cattleman.

"Before you spill your bad news, Billee," suggested Mr. Merkel, "maybe I ought to say a few words about what I've done. But also let me ask you if this Death Valley of yours is anything more than one of the picturesque names we have out here in the Golden West. You know we just naturally run to Dead Horse Gulch, Ghost Canyon and all that sort of stuff. So if your Death Valley doesn't mean more than those names, why——"

"It means a while lot more than just a name, Boss," said the old puncher solemnly. "It means real death."

"Death to whom, Billee?" asked Bud.

"To anybody that's foolish enough to try to live there and ride herd," was the short answer.

"How about the cattle?" Dick wanted to know.

"The same thing happens to them as happens to the men," said Billee in a low voice. "They just naturally die off 'fore they can be shipped to market. Believe me, Death Valley is a good place to stay away from!"

"How is it, then, Billee," asked Mr. Merkel, "that nothing happened to
me? I just came from there. I don't buy a pig in a poke. I went to
Dot and Dash and sized the place up before I closed the deal with Jed
Barter. How is it Death Valley didn't get me, Billee?"
