The Illustrated Complete Works of H.P. Lovecraft

if we expected to include it on our present flight.
    It was now 8 P.M., and we had not enough battery replacements to let our torches burn on forever. We had done so much of our studying and copying below the glacial level that our battery supply had had at least five hours of nearly continuous use; and despite the special dry cell formula would obviously be good for only about four more—though by keeping one torch unused, except for especially interesting or difficult places, we might manage to eke out a safe margin beyond that. It would not do to be without a light in these Cyclopean catacombs, hence in order to make the abyss trip we must give up all further mural deciphering. Of course we intended to revisit the place for days and perhaps weeks of intensive study and photography—curiosity having long ago got the better of horror—but just now we must hasten. Our supply of trail-blazing paper was far from unlimited, and we were reluctant to sacrifice spare notebooks or sketching paper to augment it; but we did let one large notebook go. If worst came to worst, we could resort to rock-chipping—and of course it would be possible, even in case of really lost direction, to work up to full daylight by one channel or another if granted sufficient time for plentiful trial and error. So at last we set off eagerly in the indicated direction of the nearest tunnel.
    According to the carvings from which we had made our map, the desired tunnel-mouth could not be much more than a quarter-mile from where we stood; the intervening space shewing solid-looking buildings quite likely to be penetrable still at a sub-glacial level. The opening itself would be in the basement—on the angle nearest the foothills—of a vast five-pointed structure of evidently public and perhaps ceremonial nature, which we tried to identify from our aërial survey of the ruins. No such structure came to our minds as we recalled our flight, hence we concluded that its upper parts had been greatly damaged, or that it had been totally shattered in an ice-rift we had noticed. In the latter case the tunnel would probably turn out to be choked, so that we would have to try the next nearest one—the one less than a mile to the north. The intervening river-course prevented our trying any of the more southerly tunnels on this trip; and indeed, if both of the neighbouring ones were choked it was doubtful whether our batteries would warrant an attempt on the next northerly one—about a mile beyond our second choice.
    As we threaded our dim way through the labyrinth with the aid of map and compass—traversing rooms and corridors in every stage of ruin or preservation, clambering up ramps, crossing upper floors and bridges and clambering down again, encountering choked doorways and piles of debris, hastening now and then along finely preserved and uncannily immaculate stretches, taking false leads and retracing our way (in such cases removing the blind paper trail we had left), and once in a while striking the bottom of an open shaft through which daylight poured or trickled down—we were repeatedly tantalised by the sculptured walls along our route. Many must have told tales of immense historical importance, and only the prospect of later visits reconciled us to the need of passing them by. As it was, we slowed down once in a while and turned on our second torch. If we had had more films we would certainly have paused briefly to photograph certain bas-reliefs, but time-consuming hand copying was clearly out of the question.
    I come now once more to a place where the temptation to hesitate, or to hint rather than state, is very strong. It is necessary, however, to reveal the rest in order to justify my course in discouraging further exploration. We had wormed our way very close to the computed site of the tunnel’s mouth—having crossed a second-story bridge to what seemed plainly the tip of a pointed wall, and descended to a ruinous corridor especially rich in decadently elaborate and apparently ritualistic sculptures of late workmanship—when, about 8:30 P.M., Danforth’s keen young nostrils gave us the first hint of something unusual. If we had had a dog with us, I suppose we would have been warned before. At first we could not precisely say what was wrong with the formerly crystal-pure air, but after a few seconds our memories reacted only too definitely. Let me try to state the thing without flinching. There was an odour—and that odour was
