Directly behind the house we unwrapped two of the packages. One proved to be a set of surveyor’s instruments which the civil engineer quickly assembled. The other looked very much like a radio set with its loop aerials and dials, although there was no speaker or headphone with it. The radio set was placed on a small folding table, and Mr. Easton sighted from that point, while I acted as roadman and Mr. Brandon as chainman. We measured off a distance of two thousand feet in a straight line along the beach, the doctor following with the other package. At that point, the other radio-like machine was assembled and placed on a folding table. We left Mr. Brandon with this machine, and went back to the first one. “Now, Evans,” said my friend. “You and Mr. Easton go back to the house and keep Miss Van Loan company. As soon as it begins to get dark go into the living room and occupy the same positions as last night. Mr. Easton has a false beard with him, and will be disguised to look like me. Caution Miss Van Loan, when she is inside the house, to address Mr. Easton by my name. Do not, under any circumstances, tell her this while you are in the house. When you hear my motor racing outside, come out. Mr. Easton will remain. Rafferty will then go in to take your place. Is everything clear?” “Perfectly.” We found Miss Van Loan on the porch, and I whispered our plans to her while Easton adjusted his whiskers. He was about the same build and height as the doctor, and thus disguised, bore considerable resemblance to him. We chatted on the porch until dusk, then went into the living room and took our seats. Presently the door opened and closed as on the night before. Then the lights went out. Hearing a rustling sound near the door, I looked, and saw the gleaming print of a human foot forming on the carpet. In a moment another had formed in front of it while the rustling sound continued. The first footprint disappeared and a third formed in front of the second. It was as if some invisible entity were walking toward the center of the room, leaving luminous tracks which disappeared each time a foot was lifted. The footprints stopped, and drew together, side by side, in the center of the room. Then there was a slight thump, and a wispy form, similar to the one we had seen the night before, began to materialize while the two footprints slowly faded. The thing reached a height of more than six feet, wabbling this way and that as if scarcely able to support its own weight, while the horrible odor we had noticed the night before permeated the room.
