Another clarified point was that pertaining to Robert's curiously dulled and thickened speech—as well as to the general awkwardness and sense of misfit bodily parts of which he had complained. This, at the outset, was a puzzle indeed; though after long thought the clue occurred to me. Here again was the same reversal which affected perspective and coloration. Anyone in the fourth dimension must necessarily be reversed in just this way—hands and feet, as well as colors and perspectives, being changed about. It would be the same with all the other dual organs, such as nostrils, ears, and eyes. Thus Robert had been talking with a reversed tongue, teeth, vocal cords, and kindred speech-apparatus; so that his difficulties in utterance were little to be wondered at.
As the morning wore on, my sense of the stark reality and maddening urgency of the dream-disclosed situation increased rather than decreased. More and more I felt that something must be done, yet realized that I could not seek advice or aid. Such a story as mine—a conviction based upon mere dreaming—could not conceivably bring me anything but ridicule or suspicions as to my mental state. And what, indeed, could I do, aided or unaided, with as little working data as my nocturnal impressions had provided? I must, I finally recognized, have more information before I could even think of a possible plan for releasing Robert. This could come only through the receptive conditions of sleep, and it heartened me to reflect that according to every probability my telepathic contact would be resumed the moment I fell into deep slumber again.
I accomplished sleeping that afternoon, after a midday dinner at which, through rigid self-control, I succeeded in concealing from Browne and his wife the tumultuous thoughts that crashed through my mind. Hardly had my eyes closed when a dim telepathic image began to appear; and I soon realized to my infinite excitement that it was identical with what I had seen before. If anything, it was more distinct; and when it began to speak I seemed able to grasp a greater proportion of the words.
During this sleep I found most of the morning's deductions confirmed, though the interview was mysteriously cut off long prior to my awakening. Robert had seemed apprehensive just before communication ceased, but had already told me that in his strange fourth-dimensional prison colors and spatial relationships were indeed reversed—black being white, distance increasing apparent size, and so on.
He had also intimated that, notwithstanding his possession of full physical form and sensations, most human vital properties seemed curiously suspended. Nutriment, for example, was quite unnecessary—a phenomenon really more singular than the omnipresent reversal of objects and attributes, since the latter was a reasonable and mathematically indicated state of things. Another significant piece of information was that the only exit from the glass to the world was the entrance-way, and that this was permanently barred and impenetrably sealed, so far as egress was concerned.
That night I had another visitation from Robert; nor did such impressions, received at odd intervals while I slept receptively-minded, cease during the entire period of his incarceration. His efforts to communicate were desperate and often pitiful; for at times the telepathic bond would weaken, while at other times fatigue, excitement, or fear of interruption would hamper and thicken his speech.
I may as well narrate as a continuous whole all that Robert told me throughout the whole series of transient mental contacts—perhaps supplementing it at certain points with facts directly related after his release. The telepathic information was fragmentary and often nearly inarticulate, but I studied it over and over during the waking intervals of three intense days; classifying and cogitating with feverish diligence, since it was all that I had to go upon if the boy were to be brought back into our world.
The fourth-dimensional region in which Robert found himself was not, as in scientific romance, an unknown and infinite realm of strange sights and fantastic denizens; but was rather a projection of certain limited parts of our own terrestrial sphere within an alien and normally inaccessible aspect or direction of space. It was a curiously fragmentary, intangible, and heterogeneous world—a series of apparently dissociated scenes merging indistinctly one into the other; their constituent details having an obviously different status from that of an object drawn into the ancient mirror as Robert had been drawn. These scenes were like dream-vistas or magic-lantern images—elusive visual impressions of which the boy was not really a part, but which formed a sort of panoramic background or ethereal environment against which or amidst which he moved.
