From profiles that Platt had made they found the swamp at its upper point to be much lower than the level of the river, which ran beyond low hills nearly a mile away; but the river made a detour, including a considerable fall, coming back again to within a scant half-mile of the southern end of the tract, where it was much lower than the marsh. Between marsh and river at the south was an immense hill, too steep and rugged for any practical purpose, and this they scaled.

The west end of the city lay before them crowding close to the river bank, and already its tentacles had crept around and over the hills and on past Westmarsh tract. Young Platt looked from river to swamp, his eyes glowing over the possibilities that lay before them.

“Mr. Burnit,” he announced, after a gravity of thought which he strove his best to make take the place of experience, “you ought to be able to buy this hill very cheaply. Just through here we’ll construct our drainage channel, and with the excavation fill your marsh. It is one of the neatest opportunities I have ever seen, and I want to congratulate you upon your shrewdness in having picked out such a splendid investment.”

This, Bobby felt, was praise from Cæsar, and he was correspondingly elated.

He did not return to the study until in the afternoon. He found Johnson livid with abhorrence of Applerod’s gaudy metamorphosis. That gentleman wore a black frock-coat, a flowered gray waistcoat, pin-striped light trousers, shining new shoes, sported a gold-headed cane, and on the table was the glistening new silk hat which had reposed upon his snow-white curls. His pink face was beaming as he rose to greet his partner.

“Mr. Burnit,” said he, shaking hands with almost trembling gravity and importance, “this day is the apex of my life, and I’m happy to have the son of my old and revered employer as my partner.”

“I hope that it may prove fortunate for both of us,” replied Bobby, repressing his smile at the acquisition of the “make-up” which Applerod had for years aspired to wear legitimately.

Johnson, humped over the desk that had once been Bobby’s father’s, snorted and looked up at the stern portrait of old John Burnit; then he drew from the index-file which he had already placed upon the back of that desk a gray-tinted envelope which he handed to Bobby with a silence that was more eloquent than words. It was inscribed:

To my Son if he is Fool Enough to Take up With Applerod’s Swamp Scheme

Rather impatiently Bobby tore it open, and on the inside he found:
