“Suppose we drain it,” suggested Bobby, holding both his temper and his business object remarkably well in hand. “Will you stand your share of the cost?”

“It strikes me as an entirely unnecessary expense at present,” said Silas and smiled again.

“Then it won’t be drained,” snapped Bobby.

Later in the evening he caught Silas laughing at him, his shoulders heaving and every yellow fang protruding. The next morning, keeping earlier hours than ever before in his life, Bobby was waiting outside Jimmy Platt’s door when that gentleman started to work.

“The first thing you do,” he directed, still with a memory of that aggravating laugh, “I want you to build a cement wall straight across the north end of my Westmarsh property.”

Mr. Platt smiled and shook his head.

“Evidently you can not buy that north eight acres, and don’t intend to drain it,” he commented, stroking sagely the sparse beginning of those slow professional whiskers. “It’s your affair, of course, Mr. Burnit, but I am quite sure that spite work in engineering can not be made to pay.”

“Nevertheless,” insisted Bobby, “we’ll build that wall.”

The previous afternoon Jimmy Platt had made a scale drawing of the property from city surveys, and now the two went over it carefully, discussing it in various phases for fully an hour, proving estimates of cost and general feasibility. At the conclusion of that time Bobby, well pleased with his own practical manner of looking into things, telephoned to Johnson and asked for Applerod. Mr. Applerod had not yet arrived.

“Very well,” said Bobby, “when he comes have him step out and secure suitable offices for us,” and this detail despatched he went out with his engineer to make a circuit of the property and study its drainage possibilities.
