"Positively I am getting stupid!" he grumbled half aloud. "Of course! Of course! Why couldn't I have thought of that in the first place?..."

So it came about that Grayson did not go to his office on the following morning at the usual time. Instead, he called again upon The Thinking Machine in eager, expectant response to a note which had reached him at his home just before he started to his office.

"Nothing yet," said The Thinking Machine as the financier entered. "But here is something you must do today. At one o'clock," the scientist went on, "you must issue orders for a gigantic deal of some sort; and you must issue them precisely as you have issued them in the past; there must be no variation. Dictate the letters as you have always done to Miss Winthrop—but don't send them! When they come to you, keep them until you see me."

"You mean that the deal must be purely imaginative?" inquired the financier.

"Precisely," was the reply. "But make your instructions circumstantial; give them enough detail to make them absolutely logical and convincing."

Grayson asked a dozen questions, answers to which were curtly denied, then went to his office. The Thinking Machine again called Hatch on the telephone.

"I've got it," he announced briefly. "I want the best telegraph operator you know. Bring him along and meet me in the room on the top floor where the telephone is at precisely fifteen minutes before one o'clock today."

"Telegraph operator?" Hatch repeated.

"That's what I said—telegraph operator!" replied the scientist irritably. "Goodbye."

Hatch smiled whimsically at the other end as he heard the receiver banged on the hook—smiled because he knew the eccentric ways of this singular man, whose mind so accurately illuminated every problem to which it was directed. Then he went out to the telegraph room and borrowed the principal operator. They were in the little room on the top floor at precisely fifteen minutes of one.
