Professor Webb had been engaged, forty-eight years before, in a tour of Greenland and Iceland in search of some Runic inscriptions which he failed to unearth; and whilst high up on the West Greenland coast had encountered a singular tribe or cult of degenerate Eskimos whose religion, a curious form of devil-worship, chilled him with its deliberate bloodthirstiness and repulsiveness. It was a faith of which other Eskimos knew little, and which they mentioned only with shudders, saying that it had come down from horribly ancient eons before ever the world was made. Besides nameless rites and human sacrifices there were certain queer hereditary rituals addressed to a supreme elder devil or _tornasuk_; and of this Professor Webb had taken a careful phonetic copy from an aged _angekok_ or wizard-priest, expressing the sounds in Roman letters as best he knew how. But just now of prime significance was the fetish which this cult had cherished, and around which they danced when the aurora leaped high over the ice cliffs. It was, the professor stated, a very crude bas-relief of stone, comprising a hideous picture and some cryptic writing. And as far as he could tell, it was a rough parallel in all essential features of the bestial thing now lying before the meeting. These data, received with suspense and astonishment by the assembled members, proved doubly exciting to Inspector Legrasse; and he began at once to ply his informant with questions. Having noted and copied an oral ritual among the swamp cult-worshipers his men had arrested, he besought the professor to remember as best he might the syllables taken down amongst the diabolist Eskimos. There then followed an exhaustive comparison of details, and a moment of really awed silence when both detective and scientist agreed on the virtual identity of the phrase common to two hellish rituals so many worlds of distance apart. What, in substance, both the Eskimo wizards and the Louisiana swamp-priests had chanted to their kindred idols was something very like this--the word-divisions being guessed at from traditional breaks in the phrase as chanted aloud: "_Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn._" Legrasse had one point in advance of Professor Webb, for several among his mongrel prisoners had repeated to him what older celebrants had told them the words meant. This text, as given, ran something like this: "In his house at R'lyeh dead Cthulhu waits dreaming." * * * * * And now, in response to a general urgent demand, Inspector Legrasse related as fully as possible his experience with the swamp worshipers; telling a story to which I could see my uncle attached profound significance. It savored of the wildest dreams of myth-maker and theosophist, and disclosed an astonishing degree of cosmic imagination among such half-castes and pariahs as might be least expected to possess it.
