"Just what do you know?" asked Dick.

"Do you know what caused the deaths?" Bud inquired.

"No, I can't say I do," was the somewhat hesitant answer. "And that's the mysterious part of it. Only I know I came mighty near passing out and I don't want to do it again."

"Suppose you finish telling us all about it," suggested Bud, the while he looked in the direction taken by the old man who had disappeared. But the picturesque figure was out of sight.

"Well, as I was mentioning, I've been knocking around the country quite a bit," resumed Sam. "I'd have a job first on one ranch and then on another. You fellows know how it is," he said, looking at Snake and Yellin' Kid.

"Sure!" they murmured.

"Well, finally I ended up here and I must say Mr. Barter treated me all right, as he did his other hands. But when cattle began to be found dead all over the place, and when some men and their horses began to pass out, I began to get worried. So did a lot of others and they left so fast it was hard work to run the place with the few hands left.

"I was just getting ready to light out and look for another job when a man came to look the Dot and Dash over with a view, so Mr. Barter said, to buying it. Right after that Dolan, who had agreed to stay, quit sudden like, so I promised to stick and help the boss out and I did. The place was sold, and you say your dad bought it?" he asked, looking at Bud.

"Yes, this is now part of the Merkel holdings," was the answer. "Though my father didn't know anything about the queer deaths on the place when he agreed to buy it. He didn't even know that this was called Death Valley."

"Not until he got back to Diamond X and I told him," put in Billee. "Then he said he wasn't going to back out, 'specially after these boys begged for a chance to chase the jinx."
