“It is their purpose,” he concluded, “to crack open the earth’s crust by these repeated shocks, so the water from the oceans will pour into the globe’s interior. There, coming into contact with incandescent matter, steam will be generated until there is an explosion that will split the planet in two.”

“How can these Chinamen produce an artificial quaking of the earth?” asked the President.

“That,” replied the astronomer frankly, “I am not prepared to answer yet—although I have a strong suspicion of the method employed.”

For the greater part of an hour the gentlemen questioned the astronomer. They did not express doubt of his veracity in his account of the Seuen-H’sin, but merely questioned his judgment in attributing to that sect the terrible power to control the internal forces of the earth.

“You are asking us,” objected the Secretary of State, “virtually to return to the Dark Ages and believe in magicians and sorcerers and supernatural events!”

“Not at all!” returned the astronomer. “I am asking you to deal with modern facts—to grapple with scientific ideas that are so far ahead of our times the world is not prepared to accept them!”

“Then you believe that an unheard-of group of Chinamen, hiding in some remote corner of the globe, has developed a higher form of science than the brightest minds of all the civilized nations?” remarked the Attorney General.

“Events of the last few weeks seem to have demonstrated that,” replied Dr. Gresham.

“But,” protested the President, “if these Mongolians aim at splitting the globe to project a new moon into the sky, why should they be satisfied with an entirely different object—the acquisition of temporal power?”
