sorcerers, equally unscrupulous methods were justified. He proposed that the nations inform "KWO" they would surrender, to ward off the immediate resumption of the earthquakes and give the naval expedition time to accomplish its work.
But the governments could not agree upon any course of action; and in this indecision the last day of grace drew toward its close.
As midnight approached, vast crowds assembled about the newspaper offices, eager to learn what was going to happen.
At last the fateful hour came—and passed in silence. The world had failed to concede its surrender.
Five minutes more slipped into eternity.
Then there was a sudden stir as bulletins appeared. Their message was brief. At three minutes past 12 o'clock the wireless at the United States Naval Observatory had received this communication:
"To All Mankind:
"I have given the world an opportunity to continue in peace and prosperity. My offer has been rejected. The responsibility is upon your own heads. This is my final message to the human race.
"KWO."
Within an hour the earthquakes resumed. And they were repeated, as before, exactly eleven minutes and six seconds apart.
With their reappearance vanished the last vestige of doubt that the terrestrial disturbances were due to human agency—to a being powerful enough to do what he chose with the planet.
By the end of three days it was noticed that the shocks were increasing in violence much more swiftly than previously, as if the earth's crust had been so weakened that it could no longer resist the hammering.
At this juncture Dr. Gresham announced that he was ready to leave for the Pacific Coast. The government had one of its giant mail planes waiting at an aviation field on Long Island, and in its comfortable enclosed interior we were whisked across the continent.
In less than two days we alighted at the Mare Island Navy Yard, where the Albatross, the destroyer that was to serve for our expedition, lay at our disposal.
The Albatross was the newest, largest and fastest destroyer of the Pacific fleet—an oil-burning craft carrying a crew of 117 men.
Most of the boxes and crates of material that we had sent from New York being already on deck, the astronomer immediately went to work with a corps of the navy's electricians to assemble his apparatus.
I was sent off to find six men tailors all familiar with the making of theatrical costumes, who were willing to undertake a mysterious and dangerous sea voyage; also two actors skilled in make-up.
All during this time the earthquakes never varied from their intervals of eleven minutes and six seconds, and the seriousness of affairs throughout the world continued to grow. In Europe and America deep fissures, sometimes hundreds of miles long, now appeared in the ground. Gradually it became apparent that these cracks in the earth's crust were confined within a definite area, which roughly formed a circle touching the Mississippi River on the west and Serbia on the east.
Then, on the morning after our arrival in San Francisco, half a dozen noted scientists—none of whom, however, belonged to the little group that had been taken into Dr. Gresham's confidence regarding the Seuen-H'sin—issued a warning to the public.
They prophesied that the world soon would be rent by an explosion, and that the portion within the circular area already outlined would be blown away into space or would be pulverized.
Nearly one-fifth of the entire surface of the earth was included in this doomed circle, embracing the most civilized countries of the globe—the eastern half of the United States and Canada; all of the British Isles, France, Spain, Italy, Portugal, Switzerland, Belgium, Holland and Denmark; and most of Germany, Austria-Hungary and Brazil. Here, too, were located the world's greatest cities—New York, London, Paris, Berlin, Vienna, Rome, Chicago, Boston, Washington and Philadelphia.
The scientists urged the people of the eastern United States and Canada to flee immediately beyond the Rocky Mountains, while the inhabitants of western Europe were advised to take refuge east of the Carpathians.
The first result of this warning was simply to daze the public. But in a few hours the true character of the predicted happenings dawned upon people in full force. Then terror—blind, sickening, unreasoning terror—seized the masses, and there began the most gigantic and terrible exodus in the history of the earth—a migration that in a few hours developed into a mad race of half the planet's inhabitants across thousands of miles.
Transportation systems were seized by the frenzied throngs and rendered useless in the jam. People started frantically in airplanes, automobiles, horsedrawn vehicles—even on foot. All restraints of law and order vanished in the hideous struggle of "every man for himself."
At last, toward midnight of this day, Dr. Gresham finished his work. Together we made a final tour of inspection through the ship—which gave me my first opportunity to see most of the scientific paraphernalia the doctor had constructed.
Electrical equipment was scattered everywhere—several big generators, a whole battery of huge induction coils, submarine telephones, switchboards with strange clocklike devices mounted upon them, and reels of heavy copper wire.
One thing that particularly attracted my attention was an instrument at the very bottom of the ship's hold. It looked like the seismographs used on land for recording earthquakes. I observed, too, that the wireless telegraph equipment of the destroyer had been much enlarged, giving it a wide radius.
The crated parts of two hydroplanes lay on deck, besides half a dozen light, portable mountain mortars, with a quantity of high-explosive ammunition.
At the finish of our inspection, the doctor sought Commander Mitchell, the vessel's chief officer, and announced:
"You may start at once—on the course I have outlined."
A few minutes later we were silently speeding toward the Golden Gate.
Dr. Gresham and I then went to bed.
When we awoke the next morning we were out of sight of land and were steaming at full speed north in the Pacific Ocean.
CHAPTER VI.
THE COASTS OF MYSTERY
HOUR after hour the destroyer kept up her furious pace almost due north in the Pacific. We never came in sight of land, and it was impossible for me to guess whither we were bound.
Throughout the first day Dr. Gresham remained in his stateroom—silent, troubled, buried in a mass of arithmetical calculations.
In another part of the ship the six tailors I had brought on board labored diligently upon a number of Chinese
