"Diamond-studded ones!" he exulted. "Why, Agnes, the office is besieged with requests for allotments. In spite of the fact that we have over eleven hundred lots for sale at an average price of six hundred dollars, we're not going to have enough to go around. The receipts will be fully seven hundred thousand dollars, and our complete disbursements, by the time we have sold out, will not amount to over two hundred and twenty-five thousand. Of course, I don't know--I haven't asked, and you wouldn't tell me if I did--just by what promises you are bound, but when I close up this deal you're going to marry me! That's flat!" "You mustn't be too sure of anything in this world, Bobby," she warned him, but she turned upon him a smile that made her words but idle breath. CHAPTER XI BOBBY DISCOVERS AN ENEMY GREATER THAN SILAS TRIMMER One circumstance only had occurred to give Bobby any anxiety. With the beginning of the thaw the water in Silas Trimmer's eight acres had begun slowly to rise, and he saw with some dismay that by far the larger part of the great natural basin from which the surface water had been supplied to this swamp sloped from the northern end. Not having that expanse of one hundred and twenty acres to spread over, it might overflow, and in considerable trepidation he sought Jimmy Platt. That happy young gentleman only smiled. "I calculated upon that," he informed Bobby, "and built your retaining wall two feet higher than the normal spring level for that very reason. It will carry all the water than can shed down from those hills." Relieved, Bobby went ahead with the preparations for turning the Applerod Addition into money, and though he saw the water creeping up steadily against the other side of his wall, he displayed no anxiety until it had reached within three or four inches of the top. Then he took Platt out with him to have a look at it. "Don't you think you ought to get busy?" he inquired. "Hadn't we better add another foot to this wall?" "Not necessary," said Jimmy, shaking his head positively. "This has been an unusual spring, but the wet weather is all over now, and you can see by the water-mark where the level has gone down a half inch since morning. All the moisture that has been trickling down here during the past week has been from the thawing out of the frozen hillsides, but those slopes are almost dust dry now." "Suppose it should rain again?" insisted Bobby, still worried. "It couldn't rain hard enough to fill up these four inches," declared Platt with decision. "Look here, Mr. Burnit, I'd worry myself if there was any cause whatever. Do you suppose I'd want anything to happen to my biggest and best job so close to my wedding-day?" "So you've set the time," said Bobby, with eager pleasure. He had met Platt's "best girl" and her mother out at the Addition, and liked her, as he did earnest young Platt. "June the first," replied Jimmy exultantly. "The date of your opening--in the evening."
