We never--even in our wildest Halloween moods--visited this cellar by night, but in some of our daytime visits could detect the phosphorescence, especially when the day was dark and wet. There was also a subtler thing we often thought we detected--a very strange thing which was, however, merely suggestive at most. I refer to a sort of cloudy whitish pattern on the dirt floor--a vague, shifting deposit of mold or niter which we sometimes thought we could trace amidst the sparse fungous growths near the huge fireplace of the basement kitchen. Once in a while it struck us that this patch bore an uncanny resemblance to a doubled-up human figure, though generally no such kinship existed, and often there was no whitish deposit whatever. On a certain rainy afternoon when this illusion seemed phenomenally strong, and when, in addition, I had fancied I glimpsed a kind of thin, yellowish, shimmering exhalation rising from the nitrous pattern toward the yawning fireplace, I spoke to my uncle about the matter. He smiled at this odd conceit, but it seemed that his smile was tinged with reminiscence. Later I heard that a similar notion entered into some of the wild ancient tales of the common folk--a notion likewise alluding to ghoulish, wolfish shapes taken by smoke from the great chimney, and queer contours assumed by certain of the sinuous tree-roots that thrust their way into the cellar through the loose foundation-stones. 2 Not till my adult years did my uncle set before me the notes and data which he had collected concerning the shunned house. Doctor Whipple was a sane, conservative physician of the old school, and for all his interest in the place was not eager to encourage young thoughts toward the abnormal. His own view, postulating simply a building and location of markedly unsanitary qualities, had nothing to do with abnormality; but he realized that the very picturesqueness which aroused his own interest would in a boy's fanciful mind take on all manner of gruesome imaginative associations.
