the final monosyllables and of the odd name Yog-Sothoth, which he had come to recognise under various spellings from other things he had seen in connection with this horrible matter. The formulae were as follows—exactly so, as Willett is abundantly able to testify—and the first one struck an odd note of uncomfortable latent memory in his brain, which he recognised later when reviewing the events of that horrible Good Friday of the previous year. So haunting were these formulae, and so frequently did he come upon them, that before the doctor knew it he was repeating them under his breath. Eventually, however, he felt he had secured all the papers he could digest to advantage for the present; hence resolved to examine no more till he could bring the sceptical alienists en masse for an ample and more systematic raid. He had still to find the hidden laboratory, so leaving his valise in the lighted room he emerged again into the black noisome corridor whose vaulting echoed ceaselessly with that dull and hideous whine.
The next few rooms he tried were all abandoned or filled only with crumbling boxes and ominous-looking leaden coffins; but impressed him deeply with the magnitude of Joseph Curwen's original operations. He thought of the slaves and seamen who had disappeared, of the graves which had been violated in every part of the world, and of what that final raiding party must have seen; and then he decided it was better not to think any more. Once a great stone staircase mounted at his right, and he deduced that this must have reached to one of the Curwen outbuildings—perhaps the famous stone edifice with the high slit-like windows—provided the steps he had descended had led from the steep-roofed farmhouse. Suddenly the walls seemed to fall away ahead, and the stench and the wailing grew stronger. Willett saw that he had come upon a vast open space, so great that his torchlight would not carry across it; and as he advanced he encountered occasional stout pillars supporting the arches of the roof.
After a time he reached a circle of pillars grouped like the monoliths of Stonehenge, with a large carved altar on a base of three steps in the centre; and so curious were the carvings on that altar that he approached to study them with his electric light. But when he saw what they were he shrank away shuddering, and did not stop to investigate the dark stains which discoloured the upper surface and had spread down the sides in occasional thin lines. Instead, he found the distant wall and traced it as it swept round in a gigantic circle perforated by
