None of these colloquies was ever ocularly witnessed, since the windows were always heavily draped. Once, though, during a discourse in an unknown tongue, a shadow was seen on the curtain which startled Weeden exceedingly; reminding him of one of the puppets in a show he had seen in the autumn of 1764 in Hacher's Hall, when a man from Germantown, Pennsylvania, had given a clever mechanical spectacle advertised as a "View of the Famous City of Jerusalem, in which are represented Jerusalem, the Temple of Solomon, his Royal Throne, the noted Towers, and Hills, likewise the Sufferings of Our Saviour from the Garden of Gethsemane to the Cross on the Hill of Golgotha; an artful piece of Statuary, Worthy to be seen by the Curious." It was on this occasion that the listener, who had crept close to the window of the front room whence the speaking proceeded, gave a start which roused the old Indian pair and caused them to loose the dogs on him. After that no more conversations were ever heard in the house, and Weeden and Smith concluded that Curwen had transferred his field of action to regions below.
