weapon, and my aim was good. I hit him. The "bullet" must have penetrated his body and exploded. For one moment I saw him flying through the air. Then the explosion, and he had vanished. He never finished his leap. It was annihilation.
How many more of them there were I don't know. But this must have been too much for them. They used a final round of shells on us, all of which exploded harmlessly, and shortly after I heard them swishing and crashing away from us through the tree tops. Not one of them descended to earth.
Now I had time to give some attention to my companion. She was, I found, a girl, and not a boy. Despite her bulky appearance, due to the peculiar belt strapped around her body high up under the arms, she was very slender, and very pretty.
There was a stream not far away, from which I brought water and bathed her face and wound.
Apparently the mystery of these long leaps, the monkey-like ability to jump from bough to bough, and of the bodies that floated gently down instead of falling, lay in the belt. The thing was some sort of anti-gravity belt that almost balanced the weight of the wearer, thereby tremendously multiplying the propulsive power of the leg muscles, and the lifting power of the arms.
When the girl came to, she regarded me as curiously as I did her, and promptly began to quiz me. Her accent and intonation puzzled me a lot, but nevertheless we were able to understand each other fairly well, except for certain words and phrases. I explained what had happened while she lay unconscious, and she thanked me simply for saving her life.
"You are a strange exchange," she said, eying my clothing quizzically. Evidently she found it mirth provoking by contrast with her own neatly efficient garb. "Don't you understand what I mean by 'exchange?' I mean ah—let me see—a stranger, somebody from some other gang. What gang do you belong to?" (She pronounced it "gan," with only a suspicion of a nasal sound.)
I laughed. "I'm not a gangster," I said. But she evidently did not understand this word. "I don't belong to any gang," I explained, "and never did. Does everybody belong to a gang nowadays?"
"Naturally," she said, frowning. "If you don't belong to a gang, where and how do you live? Why have you not found and joined a gang? How do you eat? Where do you get your clothing?"
"I've been eating wild game for the past two weeks," I explained, "and this clothing I—er—ah—." I paused, wondering how I could explain that it must be many hundred years old.
In the end I saw I would have to tell my story as well as I could, piecing it together with my assumptions as to what had happened. She listened patiently; incredulously at first, but with more confidence as I went on. When I had finished, she sat thinking for a long time.
"That's hard to believe," she said, "but I believe it." She looked me over with frank interest.
"Were you married when you slipped into unconsciousness down in that mine?" she asked me suddenly. I assured her I had never married. "Well, that simplifies matters," she continued. "You see, if you were technically classed as a family man, I could take you back only as an invited exchange and I, being unmarried, and no relation of yours, couldn't do the inviting."
CHAPTER II
The Forest Gangs
She gave me a brief outline of the very peculiar social and economic system under which her people lived. At least it seemed very peculiar from my 20th Century viewpoint.
I learned with amazement that exactly 492 years had passed over my head as I lay unconscious in the mine.
Wilma, for that was her name, did not profess to be a historian, and so could give me only a sketchy outline of the wars that had been fought, and the manner in which such radical changes had come about. It seemed that another war had followed the First World War, in which nearly all the European nations had banded together to break the financial and industrial power of America. They succeeded in their purpose, though they were beaten, for the war was a terrific one, and left America, like themselves, gasping, bleeding and disorganized, with only the hollow shell of a victory.
This opportunity had been seized by the Russian Soviets, who had made a coalition with the Chinese, to sweep over all Europe and reduce it to a state of chaos.
America, industrially geared to world production and the world trade, collapsed economically, and there ensued a long period of stagnation and desperate attempts at economic reconstruction. But it was impossible to stave off war with the Mongolians, who by now had subjugated the Russians, and were aiming at a world empire.
In about 2109, it seems, the conflict was finally precipitated. The Mongolians, with overwhelming fleets of great airships, and a science that far outstripped that of crippled America, swept in over the Pacific and Atlantic Coasts, and down from Canada, annihilating American aircraft, armies and cities with their terrific disintegrator rays. These rays were projected from a machine not unlike a searchlight in appearance, the reflector of which, however, was not material substance, but a complicated balance of interacting electronic forces. This resulted in a terribly destructive beam. Under its influence, material substance melted into "nothingness"; i. e., into electronic vibrations. It destroyed all then known substances, from air to the most dense metals and stone.
They settled down to the establishment of what became known as the Han dynasty in America, as a sort of province in their World Empire.
Those were terrible days for the Americans. They were hunted like wild beasts. Only those survived who finally found refuge in mountains, canyons and forests. Government was at an end among them. Anarchy prevailed for several generations. Most would have been eager to submit to the Hans, even if it meant slavery. But the Hans did not want them, for they themselves had marvelous machinery and scientific process by which all difficult labor was accomplished.
Ultimately they stopped their active search for, and annihilation of, the widely scattered groups of now savage Americans. So long as they remained hidden in their forests, and did not venture near the great cities the Hans had built, little attention was paid to them.
Then began the building of the new American civilization. Families and individuals gathered together in clans or "gangs" for mutual protection. For nearly a century they lived a nomadic and primitive life, moving from place to place, in desperate fear of the casual and occasional Han air raids, and the terrible disintegrator ray. As the frequency of these raids decreased, they began to stay permanently in given localities, organizing upon lines which in many respects were similar to those of the military households of the Norman feudal barons, except that instead of gathering together in castles, their defense tactics necessitated a certain scattering of living quarters for families and individuals. They lived virtually in the open air, in the forests, in green tents, resorting to camouflage tactics that would conceal their presence from air observers. They dug underground factories and laboratories, that they might better be shielded from the electrical detectors of the Hans. They tapped the radio communication lines of the Hans, with crude instruments at first; better ones later on. They bent every effort toward the redevelopment of science. For many generations they labored as unseen, unknown scholars of the Hans, picking up their knowledge piecemeal, as fast as they were able to.
During the earlier part of this period, there were many deadly wars fought between the various gangs, and occasional courageous but childishly futile attacks upon the Hans, followed by terribly punitive raids.
But as knowledge progressed, the sense of American brotherhood redeveloped. Reciprocal arrangements were made among the gangs over constantly increasing areas. Trade developed to a certain extent, as between one gang and another. But the interchange of knowledge became more important than that of goods, as skill in the handling of synthetic processes developed.
Within the gang, an economy was developed that was a compromise between individual liberty and a military socialism. The right of private property was limited practically to personal possessions, but private privileges were many, and sacredly regarded. Stimulation to achievement lay chiefly in the winning of various
