“We’ll have Merkle in here at once; see what he says. You’re certainly interesting—mighty interesting. If it works—if it works—”

“It’ll work, chief,” said Mr. Cooper confidently, as the president rang his buzzer to summon Isaac Merkle.

The conference with Mr. Merkle lasted over an hour. The little chemist, forgetting the unsavory circumstances under which he had been induced to begin work on Jimmy’s plan, plunged into a discussion of it with enthusiasm. His ideas, as he outlined them now to Mr. Wentworth, did not differ in any large essential from the way in which Jimmy had explained how it should be done.

Mr. Merkle was sure that coal burning under control in the ground could be made to yield gas of a very satisfactory quality. In his opinion the main furnaces that had already been decided upon for the new optical glass factory could be used, unchanged.

The president raised the question of the saving of the cost of coal; whereupon Mr. Merkle surprised Jimmy and George Cooper greatly by producing a sheet of paper with it all figured out.

“Of course y’ understand, Mr. Wentworth, I couldn’t know what this coal property is going to cost you. But when you own it—here is the saving according to the estimate we made of the fuel consumption of this new factory. But, Mr. Wentworth, coal’s going higher next year; it would be more than this.”

Mr. Wentworth looked over the figures attentively. Then he showed the chemist the little bottle of sand on his desk, explaining briefly what Jimmy had told him about it. Mr. Merkle’s eyes nearly popped from his head. Here was something he and Hope had never thought of. He waved his hands before him expressively.

“With that and producer gas next to nothing you got a cinch, Mr. Wentworth,” he stated emphatically.

The interview ended with the president thoroughly convinced as far as he had gone. He declared himself intensely interested, and stated definitely that if the thing continued to work out theoretically as it seemed now it would—and as he himself admitted he thoroughly believed it would—he certainly would see that the company gave it a fair trial.

“Too good to pass up; we’d be the first in the field to use it, too.” He chuckled to himself. “They’d never catch up with us.”
