night with no moon. We had been warned against venturing into the danger zone; several of the Wyoming patrol and numbers of private planes had been seen to fall in flames when the light struck them.
We had no idea what the danger zone was—how close we dared go—but decided to chance it. To fly sufficiently high for safety directly over the Mercutians appeared difficult, since the light‑fire already had proven effective at a distance of several miles at least. We decided not to attempt that, but merely to follow the course of the C., B. and Q. southwest to Cody, then to circle around to the east, and thence back north to Billings, passing well to the east of the Mercutians.
We started, as I have said, about midnight, rising from the rolling prairie back of Billings. We climbed five hundred feet and, with our searchlight playing upon the ground beneath, started directly for Frannie. We passed over Frannie at about eight hundred feet, and continued on the C., B. and Q. line toward Garland. We had decided to pass to a considerable extent to the west of Garland, to be farther away from the danger, and then to strike down to Cody.
We were flying now at a speed close to a hundred and forty miles an hour. Off to the left I could see the red and green beam of the single light of the Mercutians; it was pointing vertically up into the air, motionless. Something—I do not know what—made me decide to turn off our searchlight.
I looked behind us. Some miles away, and considerably nearer the Mercutians than we were, I saw the light of another plane. I was watching it when suddenly the red and green beam swung toward it, and a moment later picked it up. I caught a fleeting glimpse of what I took to be a little biplane. It remained for an instant illuminated by the weird red and green flare; then the Mercutian Light swung back to its vertical position. A second later the biplane burst into flames and fell.
The thing left me shuddering. I turned our searchlight permanently off and sat staring down at the shadowy country scurrying away beneath us.
Mercer had evidently not seen this tragedy. He did not look at me, but kept facing the front. We were now somewhat to the west of Garland, with it between us and the Mercutians. The few lights of the town could be seen plainly. The country beneath us seemed fairly level. To the west, half a mile away, perhaps, I could make out a sheer, perpendicular wall of rock. We seemed to be flying parallel with it and about level with its top.
We were rising a little, I think, when suddenly our engines stopped. I remember it flashed through my mind to wonder how Mercer would dare shut them off when we were flying so low. The sudden silence confused me a little. I started to ask him if he had seen the biplane fall, when he swung back abruptly and gripped me by the arm.
"Turn on the light—you fool—we've got to land!"
I fumbled with the searchlight. Then, just as I turned the switch, I saw, rising from a point near the base of the Mercutian Light, what appeared to be a skyrocket.
It rose in a long, graceful arc, reached the top of its ascent, and came down, still flaming. I remember deciding it would fall in or near Garland.
It seemed to go out just before it landed—at least I did not follow it all the way down. Then there came a flash as though a huge quantity of red and green smokeless powder had gone off in a puff; a brief instant of darkness, and then flames rose from a hundred points in the little town. The next second our wheels ground in the sand.
I heard a splintering crash; something struck me violently on the shoulder; then—blackness.
CHAPTER IV.
THE MEETING.
Professor Newland and his family were living in seclusion in their Florida home at the time the Mercutian invaders landed in Wyoming. The curious events in Florida, which connected them so directly with the invasion and caused Alan later to play so vital a part in it, are so important that I am impelled to relate them chronologically, rather than as they were told me afterward by Alan and Beth.
When, on March 9, the news that the Mercutians had landed in Wyoming reached Professor Newland, he immediately established telegraphic communication with Harvard. Thus he was kept fully informed on the situation—indeed, he saw it as a whole far better than I did.
On March 12, three days after the landing, orders from Washington were given out, regulating all passenger transportation in the direction of the danger zone. One hundred miles was the limit set. State troops were placed on all trains, State roads were likewise guarded, and the State airplane patrols united in a vigilant effort to keep outside planes from getting in. On the 13th the President of the United States issued an appeal to all persons living within the hundred‑mile limit, asking them to leave.
On March 14 the Canadian government offered its assistance in any way possible—its Saskatchewan airplane patrol was already helping Montana maintain the hundred‑mile limit. Similar offers were immediately made by nearly every government in the world.
Such were the first main steps taken to safeguard the people.
By March 14 the actual conditions of affairs in the threatened section of Wyoming was fairly well known. The town of Garland was destroyed by fire on the night of the 10th, and the towns of Mantua and Powell—north and south of Garland respectively—the following morning. On the evening of the 11th a government plane, flying without lights, sacrificed itself in an attempt to drop a bomb into the Mercutian camp. It was caught by the light when almost directly over the Mercutians, and was seen to fall in flames.
It was estimated that the single light was controlling an area with a radius of about ten miles. To the south and west there was practically nothing but desert. To the west Garland, Mantua and Powell were burned. To the north Deaver and Crowley—on another branch of the C., B. and Q., about ten miles from the Mercutians—were as yet unharmed. They were, however, entirely deserted by the 15th.
During these days the Mercutians did not move from their first landing place. Newspaper speculation regarding their capabilities for offensive action ran rife. Perhaps they could not move. They appeared to possess but one ray of light‑fire; this had an effective radius of ten miles. The only other offensive weapon shown was the rocket, or bomb, that had destroyed the C., B. and Q. train near Garland and the town itself. Reports differed as to what had set fire to the town of Powell.
All these points were less than ten miles away from the Mercutian base. Obviously, then, the danger was grossly exaggerated. The unknown invaders could safely and easily be shelled by artillery from a much greater distance. Mercury had passed inferior conjunction; no other Mercutian vehicles had been reported as landing anywhere on the earth. A few days, and the danger would be over. Thus the newspapers of the country settled the affair.
On March 14th it was announced that General Price would conduct the military operations against the Mercutians. Press dispatches simultaneously announced that troops, machine guns and artillery were being rushed to Billings. This provoked a caustic comment from the Preparedness League of America, to the effect that no military operations of any offensive value could be conducted by the United States against anybody or anything.
This statement was to some extent true. During the twenty years that had elapsed since the World War armament of all kinds had fallen into disuse. Few improvements in offensive weapons had been made. The military organization and equipment of the United States, and, indeed, that of many of the other great powers, was admittedly inadequate to cope with any very powerful enemy.
Professor Newland telegraphed to the War Department at Washington on the 14th, stating that in his opinion new scientific measures would have to be devised to deal with this enemy, and that whatever scientific knowledge he had on the subject was at their disposal at their request. To this telegram the government never replied.
It was a day or two after that—on the morning of the 16th, to be exact—that the next most important development in this strange affair took place. Alan Newland rose that morning at dawn and took his launch for a trip up one of the neighboring bayous. He was alone, and intended to fish
