As we later learned, the scientific mechanism by which the transition was made from the realm of the fourth dimension to our own earthly world and back again, was only effective to transport organic substances. The green light-beam was of similar limitation. An organic substance of our world upon which it struck was changed in vibration rate and space-time co-ordinates to coincide with the characteristics with which the light-current was endowed. Thus the invaders used their beams as a weapon. The light flung whatever it touched of organic material with horrible speed of transition away into the Unknown—to the fourth, fifth, or perhaps still other realms. In effect—annihilation.

The mechanism of wires and dials (and small disks which were storage batteries of the strange current) was of slower, more controllable operation. Thus it could be used for transportation—for space-time traveling, as Earth scientists later came to call it. The invaders, wearing this mechanism, materialized at will into the state of matter existing in our world—and by a reversal of the co-ordinates of the current, dematerialized into the more tenuous state of their own realm.Return to text

We were soon to learn also that they were bringing into our world weapons, food, clothing and a variety of equipment by encasing the articles in containers operated by these same mechanisms of wires carrying the transition current. The transportation was possible because all the articles they brought with them were of organic substance.Return to text

The extent of the Fourth Dimensional world was never made wholly clear to us. Its rugged surface was coincident with the surface of our earth at Bermuda, at New York City, and at many points along the Atlantic seaboard of the United States. For the rest, there is no data upon which one may even guess.Return to text

The vehicles were constructed of a material allied in character to that used for garments by the people of this realm. It was not metal, but an organic vegetable substance.Return to text

What we learned of the science of the invisible realm was perforce picked piecemeal by us from all that we saw, experienced, and what several different times Tako was willing to explain to us. And it was later studied by the scientists of our world, whose additional theories I can incorporate into my own knowledge. Yet much of it remains obscure. And it is so intricate a subject that even if I understood it fully I could do no more than summarize here its fundamental principles.

The space-transition of these vehicles, Tako had already told us, was closely allied to the transition from his world to ours. And the weapons were of the same principles. The science of space-transition, limited to travel from one portion of the realm to another, quite evidently came first. The weapons, the forcible, abrupt transition of material objects out of the realm into other dimensions—into the Unknown—this principle was developed from the traveling. And from them both Tako himself evolved the safe and controlled transition from his world to ours.

Concerning the operation of these vehicles: Motion, in our Earth-world or any other, is the progressive change of a material object in relation to its time and space. It is here now, but it was there. Both space and time undergo a simultaneous change; the object itself remains unaltered, save in its position.

In the case of the vehicles, the current I have already mentioned (used in the mechanism for the transition from Earth to the other realm) that current, circulating in the organic material of which the vehicle was composed, altered the state of matter of the carrier and everything within the aura of the current’s field. The vehicle and all its contents, with altered inherent vibratory rate of its molecules, atoms and electrons, was in effect projected into another world. A new dimension was added to it. It became an imponderable wraith, resting dimly visible in a sort of borderland upon the fringe of its own world.

Yet it had not changed position. It still remained quiescent. Then the current was further altered, and the time and space co-ordinates set into new combinations. This change of the current was a progressive change. Controlled and carefully calculated by what intricate theoretic principles and practical mechanisms no scientist of our world can yet say.

It is clear, however, that as this progressive change in space-time characteristics began, the vehicle perforce must move slightly in space and time to reconcile itself to the change.

There never has been a seemingly more abstruse subject for the human mind to grasp than the theories involving a true conception of space-time. Yet, doubtless, to those of Tako’s realm, inheriting, let me say, the consciousness of its reality, there was nothing abstruse about it.

An analogy may make it clearer. The vehicle, hovering in the borderland, might be called in a visible but gaseous state. A solid can be turned to gas merely by the alteration of the vibratory rate of its molecules.

This unmoving (gaseous) vehicle, is now further altered in space-time characteristics. Suppose we say it is very slightly thrown out of tune with its spatial surroundings at the time which is its present. Nature will allow no such disorganization. The vehicle, as a second of time passes, is impelled by the force of nature to be in a different place. This involves motion. A small change in the first second. Then the current alters it progressively faster. The change, of necessity, is progressively greater, the motion more rapid.

And this, controlled as to direction, became transportation. The determination of direction at first thought seems amazingly intricate. In effect, that was not so. With space-time factors set as a destination, i. e., the place where the vehicle must end its change at a certain time, all the intermediate changes become automatic. With every passing second it must be at a reconcilable place—the direction of its passage perforce being the shortest path between the two.

With this in mind, the transition from one world to another becomes more readily understandable. No natural change of space is involved, merely the change of the state of matter. It was the same change as that which carried the vehicles into a shadowy borderland, and then pushed further into new dimensional realms.

The green light-beam weapons were merely another application of the same principle. The characteristics of the green light current, touching organic matter, altered the vibratory rate of what was struck to coincide with the light. A solid cake of ice under a blow-torch becomes steam by the same principle. The light-beams were swift and violent in their action. The change in them was progressive also—but it was so swiftly violent a change that nothing living could survive the shock of the enforced transition.Return to text

Materialization bombs, we afterward called them; they played a diabolical part in the coming events. They were of many sizes and shapes, but most of them were small in size and shape, like a foot-long wedged-shaped brick, or the head of an ax. They were constructed of organic material, with a wire mesh of the transition mechanism encasing them, and an automatic operating device like the firing fuse of a bomb.Return to text

Neither Eunice Arton, nor any of the stolen girls, have ever been heard from since. Like the thousands of men, women and children who met their death in the attack upon New York, Eunice Arton was a victim of these tragic events.Return to text

The detailed nature of the scientific devices Tako used in the handling of his army during the attack never has been disclosed. I saw him using one of the eye-telescopes. There was also a telephonic device and occasionally he would discharge a silent signal radiance—a curious intermittent green flare of light. His charts of the topography of New York City were to me incomprehensible hieroglyphics—mathematical formula, no doubt; the co-ordinates of altitudes and contours of our world-space in its relation to the mountainous terrain of his world which stood mingled here with the New York City buildings.Return to text

There was a thing which puzzled me before we arrived in the carrier, and surprised me when we left it; and though I did not, and still do not wholly understand it, I think I should mention it here. Traveling in the carrier we were suspended in a condition of matter which might be termed mid way between Tako’s realm and our Earth-world. Both, in shadowy form, were visible to us; and to an observer on either world we also were visible.

Then, as the carrier landed, it receded from this sort of borderland as I have termed it, contacted with its own realm and landed. At once I saw that the shadowy outlines of New York were gone. And, to New York observers, the carriers as they landed, were invisible. The mountains—all this tumbled barren wilderness of Tako’s world—were invisible to observers in New York.

But I knew now how very close were the two worlds—a very fraction of visible “distance,” one from the other.

Then, with wires, disks and helmets—all the transition mechanism worn now by us and all of Tako’s forces—we drew ourselves a very small fraction of the way toward the Earth-world state. Enough and no more than to bring it to most tenuous, most wraithlike visibility, so that we could see the shadows of it and know our location in relation to it, which was necessary to Tako’s operations.

In this state, New York City was a wraith to us—and we were shadowy, dimly visible apparitions to New York observers. But in this slight transition, we did not wholly disconnect with the terrain of Tako’s world. There was undoubtedly—if the term could be called scientific—a depth of field to the solidity of these mountains. By that I mean, their tangibility persisted for a certain distance toward other dimensions. Perhaps it was a greater “depth of field” than the solidity of our world possesses. As to that, I do not know.

But I do know, since I experienced it, that as we sat now encamped upon this ledge, the ground under us felt only a trifle different from when we had full contact with it. There was a lightness upon us—an abnormal feeling of weight-loss—a feeling of indefinable abnormality to the rocks. Yet, to observers in New York, we were faintly to be seen, and the rocks upon which we sat were not.Return to text
