The following months were void of visible events, save that everyone swore to a slow but steady increase in the mysterious hill noises. On May Eve of 1915 there were tremors which even the Aylesbury people felt, whilst the following Hallowe'en produced an underground rumbling queerly synchronized with bursts of flame—"them witch Whateleys' doin's"—from the summit of Sentinel Hill. Wilbur was growing up uncannily, so that he looked like a boy of ten as he entered his fourth year. He read avidly by himself now; but talked much less than formerly. A settled taciturnity was absorbing him, and for the first time people began to speak specifically of the dawning look of evil in his goatish face. He would sometimes mutter an unfamiliar jargon, and chant in bizarre rhythms which chilled the listener with a sense of unexplainable terror. The aversion displayed toward him by dogs had now become a matter of wide remark, and he was obliged to carry a pistol in order to traverse the countryside in safety. His occasional use of the weapon did not enhance his popularity amongst the owners of canine guardians.
