My first glimpse of a human being of the 25th Century was obtained through a portion of woodland where the trees were thinly scattered, with a dense forest beyond.I had been wandering along aimlessly, and hopelessly, musing over my strange fate, when I noticed a figure that cautiously backed out of the dense growth across the glade. I was about to call out joyfully, but there was something furtive about the figure that prevented me. The boy's attention (for it seemed to be a lad of fifteen or sixteen) was centered tensely on the heavy growth of the trees from which he had just emerged.He was clad in rather tight-fitting garments entirely of green, and wore a helmet-like cap of the same color. High around his waist he wore a broad thick belt, which bulked up in the back across the shoulders into something of the proportions of a knapsack.As I was taking in these details, there came a vivid flash and heavy detonation, like that of a hand grenade, not far to the left of him. He threw up an arm and staggered a bit in a queer, gliding way; then he recovered himself and slipped cautiously away from the place of the explosion, crouching slightly, and still facing the denser part of the forest. Every few steps he would raise his arm, and point into the forest with something he held in his hand. Wherever he pointed there was a terrible explosion, deeper in among the trees. It came to me then that he was shooting with some form of pistol, though there was neither flash nor detonation from the muzzle of the weapon itself.After firing several times, he seemed to come to a sudden resolution, and turning in my general direction, leaped-to my amazement sailing through the air between the sparsely scattered trees in such a jump as I had never in my life seen before. That leap must have carried him a full fifty feet, although at the height of his arc, he was not more than ten or twelve feet from the ground.When he alighted, his foot caught in a projecting root, and he sprawled gently forward. I say "gently" for he did not crash down as I expected him to do. The only thing I could compare it with was a slow-motion cinema, although I have never seen one in which horizontal motions were registered at normal speed and only the vertical movements were slowed down.Due to my surprise, I suppose my brain did not function with its normal quickness, for I gazed at the prone figure for several seconds before I saw the blood that oozed out from under the tight green cap. Regaining my power of action, I dragged him out of sight back of the big tree. For a few moments I busied myself in an attempt to staunch the flow of blood. The wound was not a deep one. My companion was more dazed than hurt. But what of the pursuers?I took the weapon from his grasp and examined it hurriedly. It was not unlike the automatic pistol to which I was accustomed, except that it apparently fired with a button instead of a trigger. I inserted several fresh rounds of ammunition into its magazine from my companion's belt as rapidly as I could, for I soon heard near us, the suppressed conversation of his pursuers.There followed a series of explosions round about us, but none very close. They evidently had not spotted our hiding place, and were firing at random.I waited tensely, balancing the gun in my hand, to accustom myself to its weight and probable throw.
