Raider. But after all, we have no proof that he was taken into time. That thing, the Raider, may have merely thrown a veil of invisibility around itself, and thus vanished. A crazy idea, I admit, but not as wild as this one of time-traveling."

"You do not believe your own words, Wheeler," answered my friend. "You heard Cannell's story, and in your heart you believe it. I believe it utterly, for it is the only way of accounting for that three-year disappearance. You noticed that Cannell seemed no older, after those three years? And then, as further proof, came the thing he described to us, the Raider itself."

"We saw that," I admitted, "but all argument aside, Lantin, this idea of moving through time at will seems absurd. Of course, I've heard fantastic ideas on the subject, but how could anyone really tamper with time, the most unalterable and remorseless quantity in life?"

Lantin considered me before replying. "Such an achievement is beyond our present science," he conceded, "but it may be quite possible to the science of the future. You see my meaning? Remember, Wheeler, it is only within the last few years that our science has learned anything at all about time. Previously it was considered one of the last mysteries, never to be investigated or explained. But now, with the recent work of Einstein and Lorentz and Minkowski, we are beginning to learn something about this time. We have learned, for instance, that it is only another dimension of space itself, and that the four dimensions of any object are thus length, breadth, thickness, and duration.

"We know now that time is not fixed and unchangeable, but relative and varying, that the time of Venus is not the time of earth, and that the time of Sirius is different from either. And remember, all of this we have learned within the last few years.

"What, then, may not be learned in the next thousand years, the next ten thousand, the next million? Is it not reasonable to suggest that men will advance farther and farther in their knowledge concerning this elusive thing, time, until they finally will advance so far that they will be able to control time, to travel in it at will, and thus sweep back from their own day, back to our present age? Is it not possible that men can do this, in some century to come?"

"That men can do this?" I repeated. "Men, you say, but the thing we saw was no man, Lantin. That thing, the Raider, was very far from human."

"It is so," he admitted, "but that
