I was by this time his active and enthralled assistant, and helped him make all his decisions, not only concerning the source of bodies but concerning a suitable place for our loathsome work. It was I who thought of the deserted Chapman farmhouse beyond Meadow Hill, where we fitted up on the ground floor an operating room and a laboratory, each with dark curtains to conceal our midnight doings. The place was far from any road, and in sight of no other house, yet precautions were none the less necessary; since rumours of strange lights, started by chance nocturnal roamers, would soon bring disaster on our enterprise. It was agreed to call the whole thing a chemical laboratory if discovery should occur. Gradually we equipped our sinister haunt of science with materials either purchased in Boston or quietly borrowed from the college—materials carefully made unrecognisable save to expert eyes—and provided spades and picks for the many burials we should have to make in the cellar. At the college we used an incinerator, but the apparatus was too costly for our unauthorised laboratory. Bodies were always a nuisance—even the small guinea-pig bodies from the slight clandestine experiments in West’s room at the boarding-house.
