And, presently, as I steadied somewhat upon my emotions, I was conscious of the exceeding coldness of the night air, and of the different taste of it upon my lungs and in the mouth; and it had, as it were, a wondrous keen sharping upon my palate, and did fill the lips more in the breathing; so that it may be supposed it had more body within it than that air which did fill the plateau of the Thousandth City where was my home; for the air of every City was of difference, and the greater between one that was afar up and another nigh to the earth, as may be thought; so that many Peoples did migrate unto that level which gave them best healthfulness; but under rule, and with a guidance of quantities. And not all that were lacking of health; for, some are ever contrary. And here let me set down that, within the deeps of the Fields, there was air utter varied and wonderful, that might charm one here and likewise sorrow another that were happier elsewhere; so that all might have suiting, did they but wander, and have Reason to companion them. And thus did I go forward, full of new thoughts and olden memories, and fresh-breaking wonders; neither forgetting something of doubts and fears more than a little. And again was it most cunning strange to be out there in the Night Land--though not yet afar--where often had my fancies and imaginings led me; yet until that time never had I touched foot, in all that life, upon the outward earth. And this must be a wondrous quaint seeming thought to those of this present day. And so came I, at last, nigh to the Circle that did go about the Redoubt; and presently I was come to it; and something astonished was I that it had no great bigness; for I had looked for this by _reasoning_; having always a mind to picture things as they might be truly, and hence coming sometimes to the wonder of a great truth; but odd whiles to errors that others had not made. And now, lo! I did find it but a small, clear tube that had not two inches of thickness; yet sent out a very bright and strong light, so that it seemed greater to the eye, did one but behold from a distance. And this is but a little thing to set to the telling; yet may it give something of the newness of all; and, moreover, shall you have memory with me in this place, how that oft had I seen Things and Beast-Monsters peer over that same little tube of light, their faces coming forward out of the night. And this had I seen as child and man; for as children, we did use to keep oft a watch by hours upon an holiday-time, through the great glasses of the embrasures. And we did always hope each to be that one that should first discover a monster looking inwards upon the Mighty Pyramid, across the shining of the Circle. And these to come oft; yet presently to slink away into the night; having, in verity, no liking for that light.
