“The empire of Ssu-chuan dissolved, but the Seuen-H’sin grew greater. Its high priest attained the most terrible and far-reaching power in China. But in the second century B. C., Shi-Hwang-ti, the great military emperor, made war upon the sorcerers and drove them across the Kuen-lun mountains. Still they retained great wealth and power; and in Wu-yang they made a city that is the dream spot of the world, equipped with splendid colleges for the study of astronomy and the sciences and magic.

“As astronomical knowledge increased among the Seuen-H’sin, they came to believe that the moon once was a part of the earth, having been blown out of the hollow now filled by the Pacific Ocean. In this theory certain eminent American and French astronomers lately have concurred.

“The Chinese sorcerers conceived the idea that by scientific means the earth again could be rent asunder, and its offshoot projected into space to form a second moon. Henceforth, all their labors were directed toward finding that means. And the lust for world domination became the religion of their race.

“When I dwelt among them they seemed to be drawing near their goal—and now they probably have reached it!

“But if we may judge from these demands of Kwo-Sung-tao, their plans for world conquest have taken a new and simpler turn: by threatening to use their mysterious force to dismember the globe they hope to subjugate mankind just as effectively as they expected to do by creating a second moon and fulfilling their prophecy. Why wreck the earth, if they can conquer it by threats?

“If they are able to enforce their demands it will not be long before civilization is face-to-face with those powers of evil that grind a quarter of China’s millions beneath their ghastly rule—a rule of fanaticism and terror that would stun the world!”

Dr. Gresham paused and peered out the window. There was an unearthly look on his face when he again turned toward me.

“I have seen,” he said, “those hideous powers of the Seuen-H’sin—things of horror such as the Western mind cannot conceive! When the beating of my heart shall cease forever, when my body has been buried in the grave, and when the Seuen-H’sin’s torture scars”—he tore open his shirt and revealed frightful cicatrices upon his chest—“have vanished in the final dissolution, then, even then, I shall not forget those devils out of hell in Wu-yang, and I shall feel their power clutching at my soul!”

CHAPTER IV.
DR. GRESHAM TAKES COMMAND

It was shortly before dawn when we alighted from the train in Washington. Newsboys were calling extras:
