Weeden always watched the farm with unremitting assiduity; visiting it each night for long periods, and seldom letting a week go by without a sight except when the ground bore a footprint-revealing snow. Even then he would often walk as close as possible in the travelled road or on the ice of the neighbouring river to see what tracks others might have left. Finding his own vigils interrupted by nautical duties, he hired a tavern companion named Eleazar Smith to continue the survey during his absence; and between them the two could have set in motion some extraordinary rumours. That they did not do so was only because they knew the effect of publicity would be to warn their quarry and make further progress impossible. Instead, they wished to learn something definite before taking any action. What they did learn must have been startling indeed, and Charles Ward spoke many times to his parents of his regret at Weeden’s later burning of his notebooks. All that can be told of their discoveries is what Eleazar Smith jotted down in a non too coherent diary, and what other diarists and letter-writers have timidly repeated from the statements which they finally made – and according to which the farm was only the outer shell of some vast and revolting menace, of a scope and depth too profound and intangible for more than shadowy comprehension.
It is gathered that Weeden and Smith became early convinced that a great series of tunnels and catacombs, inhabited by a very sizeable staff of persons besides the old Indian and his wife, underlay the farm. The house was an old peaked relic of the middle seventeenth century with enormous stack chimney and diamond-paned lattice windows, the laboratory being in a lean-to toward the north, where the roof came nearly to the ground. This building stood clear of any other; yet judging by the different voices heard at odd times within, it must have been accessible through secret passages beneath. These voices, before 1766, were mere mumblings and negro whisperings and frenzied screams, coupled with curious chants or invocations. After that date, however, they assumed a very singular and terrible cast as they ran the gamut betwixt dronings of dull acquiescence and explosions of frantic pain or fury, rumblings of conversations and whines of entreaty, pantings of eagerness and shouts of protest. They appeared to be in different languages, all known to Curwen, whose rasping accents were frequently distinguishable in reply, reproof, or threatening. Sometimes it seemed that several persons must be in the house; Curwen, certain captives, and the guards of those captives. There were voices of a sort that neither Weeden nor Smith had ever heard before despite their wide knowledge of foreign parts, and many that they did seem to place as belonging to this or that nationality. The nature of the conversations seemed always a kind of catechism, as if Curwen were extorting some sort of information from terrified or rebellious prisoners.
