En route to Chalmers' home I stopped at a hardware store and purchased twenty pounds of plaster of Paris. When I entered my friend's room he was crouching by the window watching the opposite wall out of eyes that were feverish with fright. When he saw me he rose and seized the parcel containing the plaster with an avidity that amazed and horrified me. He had extruded all of the furniture and the room presented a desolate appearance.
