striking the bottom of an open shaft through which daylight poured or trickled down—we were repeatedly tantalized by the sculptured walls along our route.
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 eight thirty p.m. , Danforth’s keen young nostrils gave us the first hint of something unusual.
If we had had a dog with us, I suppost 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 odor—and that odor was vaguely, subtly, and unmistakably akin to what had nauseated us upon opening the insane grave of the horror poor Lake had dissected.
Of course, the revelation was not as clearly cut at the time as it sounds now. There were several conceivable explanations, and we did a good deal of indecisive whispering. Most important of all, we did not retreat without further investigation; for having come this far, we were loath to be balked by anything short of certain disaster.
