The substance of the walls on or through which these scenes were displayed excited but did not gratify my curiosity. The effect was as though looking through a dark mirror which gave a moving scene on a large scale. The impression was not as is that of a moving picture, but of great actual distances opening before us. Or, in another place, the view might be blocked immediately by rising ground, by trees, or by buildings. There did not appear to be any selection either of place or time. They were not scenes of dramatic moment, or of selected beauty: they were not seen from any position of special advantage. They appeared to develop at the same rate that they had done in original fact, so that, if you should wish to know what would happen next month you must watch or return at that interval, to observe it. I tried to place my hand on the wall, expecting to encounter some substance of a glassy smoothness, but I felt no physical contact whatever.--Only an inability to move my hand farther forward. My companion, more sensitive than myself to any neighbouring substance, could only tell me that she had an impression as of a transparent solidity, but of a substance which she had never previously encountered. It was another point of interest, for which I have no explanation, that these scenes, or pictures, were not continuous, nor were they divided sharply from one another, but the outlines would become faint and blurred, till they were no more than faintly-coloured mist, which, as we continued to move beside it, would again show blurred outlines that would develop, farther on, into a quite different scene. The view which we now beheld was that of a sunny downland, unfenced and green, beside which we might not have paused but for the sight of a mass of rock, the memento doubtless of some volcanic or glacial activity, which rose from the level green. It was flat-sided at its nearest view, and a figure crouched before it, with his back towards us, but somewhat sideways. He was man-like in shape and size, quite naked, olive-green in colour, with a round blue patch, of the size of a tea-plate, stained or painted between his shoulders. It may have been a mark of honour, or a sign of servitude, or of merely ornamental significance. His hair, which was thickly coarse, and black, was drawn over one shoulder in a heavy plait. He was sitting on doubled legs, the feet showing clearly. They were strangely long, and slender. The middle toe was the longest, and ended in a strong curving claw.
