As the men passed the site of Wilbur Whateley's abode they shuddered visibly, and seemed again to mix hesitancy with their zeal. It was no joke tracking down something as big as a house that one could not see, but that had all the vicious malevolence of a demon. Opposite the base of Sentinel Hill the tracks left the road, and there was a fresh bending and matting visible along the broad swath marking the monster's former route to and from the summit. Armitage produced a pocket telescope of considerable power and scanned the steep green side of the hill. Then he handed the instrument to Morgan, whose sight was keener. After a moment of gazing Morgan cried out sharply, passing the glass to Earl Sawyer and indicating a certain spot on the slope with his finger. Sawyer, as clumsy as most non-users of optical devices are, fumbled a while; but eventually focused the lenses with Armitage's aid. When he did so his cry was less restrained than Morgan's had been. "Gawd almighty, the grass an' bushes is a-movin'! It's a-goin' up--slow-like--creepin' up ter the top this minute, heaven only knows what fer!" Then the germ of panic seemed to spread among the seekers. It was one thing to chase the nameless entity, but quite another to find it. Spells might be all right--but suppose they weren't? Voices began questioning Armitage about what he knew of the thing, and no reply seemed quite to satisfy. Everyone seemed to feel himself in close proximity to phases of nature and of being utterly forbidden, and wholly outside the sane experience of mankind. 10 In the end the three men from Arkham--old, white-bearded Dr. Armitage, stocky, iron-gray Professor Rice, and lean, youngish Dr. Morgan--ascended the mountain alone. After much patient instruction regarding its focusing and use, they left the telescope with the frightened group that remained in the road; and as they climbed they were watched closely by those among whom the glass was passed around. It was hard going, and Armitage had to be helped more than once. High above the toiling group the great swath trembled as its hellish maker repassed with snail-like deliberateness. Then it was obvious that the pursuers were gaining. Curtis Whateley--of the undecayed branch--was holding the telescope when the Arkham party detoured radically from the swath. He told the crowd that the men were evidently trying to get to a subordinate peak which overlooked the swath at a point considerably ahead of where the shrubbery was now bending. This, indeed, proved to be true; and the party were seen to gain the minor elevation only a short time after the invisible blasphemy had passed it.
