"Thank you—but it isn't imagination, Doctor Allison." The man's voice had again become flat and unemotional, with the effect of withdrawal of personality. "I have reason to think I have perfected some such device.... At least I believe I now possess the means of destroying human life on a wholesale scale. There is yet more to do before we may successfully assail inorganic matter. The waves penetrate but do not as yet destroy, so that while we should easily bring dissolution to human beings we cannot yet disintegrate the walls behind which they lurk. That, however, is a detail—"

"Just like that, eh?" No one smiled at Jerry Dane's comment. Bates leaned forward.

"Where do Colcord and I come in?"

Simec, who had resumed his seat, turned to him.

"Of course—I beg your pardon. I should have explained at the outset that the discovery has never had adequate practical test. One of my assistants lost his life a month or so ago, to be sure; an extremely promising man. The incident was of value in demonstrating practically a theoretical deadliness; unfortunately, it proved also that the power energized ether waves in all directions, whereas obviously it should be within the power of the operator to send it only in a given direction."

"Otherwise," remarked Latham, "it would be as fatal to the side using it as to the army against whom it was directed."

"Precisely." Simec lifted his wine-glass and sipped slowly. "For a time," he went on, "this drawback seemed insuperable, just as it has been in wireless telegraphy. Within the past week, however, I am convinced that a solution of that difficulty has been reached. In theory and in tests on a minor scale it certainly has. My assistants, however, refuse to serve in the demonstrations at full power—which, of course, are vitally necessary—even though I engage to share a part, but not, of course, the major part, of the risk. I have been equally unfortunate in enlisting others, to whom, naturally, I was in duty bound to designate possible—in fact, extremely probable—dangers."

"In more precise words," snapped Bates, "if your invention is what you think it is your assistants are bound to die."

Simec hesitated a moment, his gleaming brow wrinkled thoughtfully.

"Well, not precisely," he said at length. "That is, not necessarily. There is, of course, as I have said, that possi—that probability. I cannot be certain. Assuming the more serious outcome materializes, there will be no further danger for those who operate; I shall have learned all that it is necessary to know." He paused. "Then war will cease; either before or immediately after the initial field application."
