The nervous and apprehensive lines had somehow vanished from the countenance, and with them, oddly enough, that lethargic, heavy expression which had been their complement. He was all vigour, readiness, confidence, now. She deemed him almost handsome, this curious, changeable brother of hers, as he beat with his fist in a measured way upon the desk-top to emphasize his words, and fastened his commanding gaze upon her.

“We took very nearly twenty thousand pounds to-day,” he went on. “This is the twenty-eighth of February. A fortnight ago today was the first settlement. I wasn't here, but Semple was—and the working of it is all in his hands. He kept as still as a mouse that first day. They had to deliver to us 26,000 shares, and they hadn't got one, but we didn't make any fuss. The point was, you see, not to let them dream that they were caught in a trap. We didn't even put the price up to par. They had to come to Semple, and say there didn't seem to be any shares obtainable just at the moment, and what would he carry them over at? That means, to let them postpone delivery for another fortnight. He was as smooth as sweet-oil with them, and agreed to carry them over till today without any charge at all. But today it was a little different. The price was up ten shillings above par. That is to say, Semple arranged with a jobber, on the quiet, d'ye see? to offer thirty shillings for our one-pound shares. That offer fixed the making-up price. So then, when they were still without shares to-day, and had to be carried over again, they had to pay ten shillings' difference on each of twenty-six thousand shares, plus the difference between par and the prices they'd sold at. That makes within a few hundreds of 20,000 pounds in cash, for one day's haul. D'ye see?”

She nodded at him, expressively. Through previous talks she had really obtained an insight into the operation, and it interested her more than she would have cared to confess.

“Well, then, we put that 20,000 pounds in our pockets,” he proceeded with a steady glow in his eyes. “A fortnight hence, that is March 14th, we ring the bell on them again, and they march up to the captain's office and settle a second time. Now what happens on the 14th? A jobber makes the price for Semple again, and that settles the new sum they have to pay us in differences. It is for us to say what that price shall be. We'll decide on that when the time comes. We most probably will just put it up another ten shillings, and so take in just a simple 13,000 pounds. It's best in the long run, I suppose, to go slow, with small rises like that, in order not to frighten anybody. So Semple says, at any rate.”

“But why not frighten them?” Louisa asked. “I thought you wanted to frighten them. You were full of that idea a while ago.”

He smiled genially. “I've learned some new wrinkles since then. We'll frighten 'em stiff enough, before we're through with them. But at the start we just go easy. If they got word that there was a 'corner,' there would be a dead scare among the jobbers. They'd be afraid to sell or name a price for Rubber Consols unless they had the shares in hand. And there are other ways in which that would be a nuisance. Presently, of course, we shall liberate some few shares, so that there may be some actual dealings. Probably a certain number of the 5,000 which went to the general public will come into the market too. But of course you see that all such shares will simply go through one operation before they come back to us. Some one of the fourteen men we are squeezing will snap them up and bring them straight to Semple, to get free from the fortnightly tax we are levying on them. In that way we shall eventually let out say half of these fourteen 'shorts,' or perhaps more than half.”

“What do you want to do that for?” The sister's grey eyes had caught a metallic gleam, as if from the talk about gold. “Why let anybody out? Why can't you go on taking their money for ever?”

Thorpe nodded complacently. “Yes—that's what I asked too. It seemed to me the most natural thing, when you'd got 'em in the vise, to keep them there. But when you come to reflect—you can't get more out of a man than there is in him. If you press him too hard, he can always go bankrupt—and then he's out of your reach altogether, and you lose everything that you counted on making out of him. So, after a certain point, each one of the fourteen men whom we're squeezing must be dealt with on a different footing. We shall have to watch them all, and study their resources, as tipsters watch horses in the paddock.

“You see, some of them can stand a loss of a hundred thousand pounds better than others could lose ten thousand. All that we have to know. We can take it as a principle that none of them will go bankrupt and lose his place on the exchange unless he is pressed tight to the wall. Well, our business is to learn how far each fellow is from the wall to start with. Then we keep track of him, one turn of the screw after another, till we see he's got just enough left to buy himself out. Then we'll let him out. See?”

“It's cruel, isn't it?” she commented, calmly meditative, after a little pause.
