An expression of pain, as of some evil memory, passed swiftly over Mary Fortune's face and she turned from gazing at the mountains to give him a warning shake of the head.

"Don't you do it!" she said; but when he asked her why not she shut her lips and looked far away.

"You must've got bit some time," he suggested cheerfully, but she refused for the moment to be drawn out.

"Perhaps," she replied, "but if that's the case my advice is all the more sound."

"No, but I'm on the inside," he went on impressively. "I know some of those big ones personally. That makes the difference; those fellows don't lose, they skim the cream off of everything. Say, I ought to know—didn't I go in there lone-handed and fight it out with a king of finance? That's the man we're in with—I can't tell you his name, now—he's the one that owns the forty-nine per cent. They're crazy about copper or he'd never have looked at me—there's some big market fight coming on. And didn't he curse and squirm and holler, trying to make me give up my control? He told me in years he had never gone into anything unless he got more than half for a gift! But I told him 'no,' I'd been euchered out of one mine; and after his expert had reported on the property he came through and gave me my way. And after that! Say, there was nothing too good for me. He agreed to spend several million dollars to pay for his share of the mine and then he gave me that roll of bills to bind the bargain we'd made. By George, I felt good, to go there with two thousand dollars and come back with a big roll of yellowbacks; but before I went away he introduced me to a friend and told him how to show me the sights.

"This friend was a broker, by the name of Buckbee, and believe me, he's on the inside. He took me around and showed me the Stock Exchange and put me wise to everything. We were up in the gallery and, on the floor below us, there were a whole lot of posts with signs; and a bunch of the craziest men in the world were fighting around those posts. Fight? They were tearing each other's clothes off, throwing paper in the air, yelling like drunk Indians, knocking each other flat. It was so rough, by George, it scared me; but Buckbee told me they were selling stocks. There were thousands of dollars in every yell they let out, they talked signs like they were deaf and dumb, and every time a man held up his right hand it meant: Sold! And they wrote it down on a slip."

Rimrock paused in his description to make some hurried adjustments as his machine slowed down to a stop, but after a hasty glance he burst into a laugh and settled back in his seat.

"Well, what do we care?" he went on recklessly. "This desert is all the same. We can sit right here and see it all, and when it comes time to go back I'll shake the old engine up. But as I was telling you, playing the stock market is all right if you've got some one to put you wise."

"No, it isn't," she answered positively. "I've been there and I know."

"Well, listen to this then," went on Rimrock eagerly, "let me show you what Buckbee can do. I dropped in at his office, after I'd received my roll, and he said: 'Want to take a flier?'
