Earl Sawyer now took the telescope and reported the three figures as standing on the topmost ridge, virtually level with the altar-stone but at a considerable distance from it. One figure, he said, seemed to be raising its hands above its head at rhythmic intervals; and as Sawyer mentioned the circumstance the crowd seemed to hear a faint, half-musical sound from the distance, as if a loud chant were accompanying the gestures. The weird silhouette on that remote peak must have been a spectacle of infinite grotesqueness and impressiveness, but no observer was in a mood for esthetic appreciation. "I guess he's sayin' the spell," whispered Wheeler as he snatched back the telescope. The whippoorwills were piping wildly, and in a singularly curious irregular rhythm quite unlike that of the visible ritual. Suddenly the sunshine seemed to lessen without the intervention of any discernible cloud. It was a very peculiar phenomenon, and was plainly marked by all. A rumbling sound seemed brewing beneath the hills, mixed strangely with a concordant rumbling which clearly came from the sky. Lightning flashed aloft, and the wondering crowd looked in vain for the portents of storm. The chanting of the men from Arkham now became unmistakable, and Wheeler saw through the glass that they were all raising their arms in the rhythmic incantation. From some farmhouse far away came the frantic barking of dogs. The change in the quality of the daylight increased, and the crowd gazed about the horizon in wonder. A purplish darkness, born of nothing more than a spectral deepening of the sky's blue, pressed down upon the rumbling hills. Then the lightning flashed again, somewhat brighter than before, and the crowd fancied that it had showed a certain mistiness around the altar-stone on the distant height. No one, however, had been using the telescope at that instant. The whippoorwills continued their irregular pulsation, and the men of Dunwich braced themselves tensely against some imponderable menace with which the atmosphere seemed surcharged.
