"You are certain that your information didn't originate right here in Mirapolis—in Mr. Cortwright's office, to locate it more exactly?"

"It didn't; it came from a purely personal source and direct from Washington."

"And the source couldn't possibly have become contaminated by the Cortwright germs?"

Harlan's smile was the face-wrinkling of seasoned wisdom.

"You are pushing me too hard," he protested. "I know that there are wheels within wheels. You'd say it would be a foxy move to have the local newspaper in Mirapolis get such a tip from a strictly unprejudiced source. I'll have to admit that myself."

Brouillard looked at his watch and reached for his hat.

"It's all right, Harlan," he said at the leave-taking. "Believe as much as you like, but take my advice in just one small matter. Don't buy Mirapolis dirt to hold; buy it to sell—and sell the minute you see your profit. I told you I'd give you a pointer if I didn't forget; you've got it."

For the better part of a fortnight the tidal waves of prosperity, as evinced by increasing speculative values, kept on rolling in, each one apparently a little higher than its immediate predecessor. Then the flood began to subside, though so slowly that at first it was only by a careful comparison of the daily transfers that the recession could be measured.

Causes and consequences extraneous to the city itself contributed to the almost imperceptible reactionary tendency. For one, the Buckskin Mining and Milling Company reluctantly abandoned its pastime of ploughing barren furrows on Jack's Mountain, and a little later went into liquidation, as the phrase ran, though the Eastern bondholders probably called it bankruptcy. About the same time the great cement plant, deprived of the government market by the slackening of the work on the dam, reduced its output to less than one fourth of its full capacity. Most portentous of all, perhaps, was the rumor that the placers at Quadjenàï were beginning to show signs of exhaustion. It was even whispered about that the two huge gold dredges recently installed were not paying the expenses of operating them.

Quite naturally, the pulse of the Wonder City beat sensitive to all these depressive rumors and incidents, responding slowly at first but a little later in accelerated throbbings which could no longer be ignored by the most optimistic bidder at the "curb" exchanges.
