“ ‘And pray explain further. What is an Elemental?’
“Once again his eye dilated.
“ ‘It will take two minutes,’ he said. ‘But, listen. There are good things in this world, are there not, and bad things? Cancer, I take it is bad, and—and fresh air is good; honesty is good, lying is bad. Impulses of some sort direct both sides, and some power suggests the impulses. Well, I went into this spiritualistic business impartially. I learned to “expect,” to throw open the door into the soul, and I said, “Anyone may come in.” And I think Something has applied for admission, the Thing that tapped and turned the table and struck matches, as you saw, across it. Now the control of the evil principle in the world is in the hands of a power which entrusts its errands to the things which I call Elementals. Oh, they have been seen; I doubt not that they will be seen again. I did not, and do not ask good spirits to come in. I don’t want “The Church’s one foundation” played on a musical box. Nor do I want an Elemental. I only threw open the door. I believe the Thing has come into my house, and is establishing communication with me. Oh, I want to go the whole hog. What is it? In the name of Satan, if necessary, what is it? I just want to know.’
“What followed I thought then might easily be an invention of the imagination, but what I believed to have happened was this. A piano with music on it was standing at the far end of the room by the door, and a sudden draught entered the room, so strong that the leaves turned. Next the draught troubled a vase of daffodils, and the yellow heads nodded. Then it reached the candles that stood close to us, and they fluttered, burning blue and low. Then it reached me, and the draught was cold, and stirred my hair. Then it eddied, so to speak, and went across to Louis, and his hair also moved, as I could see. Then it went downwards towards the fire, and flames suddenly started up in its path, blown upwards. The rug by the fireplace flapped also.
“ ‘Funny, wasn’t it?’ he asked.
“ ‘And has the Elemental gone up the chimney?’ said I.
“ ‘Oh, no,’ said he, ‘the Thing only passed us.’
“Then suddenly he pointed at the wall just behind my chair, and his voice cracked as he spoke.
“ ‘Look, what’s that?’ he said. ‘There on the wall.’
“Considerably startled I turned in the direction of his shaking finger. The wall was pale grey in tone, and sharp-cut against it was a shadow that, as I looked, moved. It was like the shadow of some enormous slug, legless and fat, some two feet high by about four feet long. Only at one end of it was a head shaped like the head of a seal, with open mouth and panting tongue.
“Then even as I looked it faded, and from somewhere close at hand there sounded another of those shattering knocks.
“For a moment after there was silence between us, and horror was thick as snow in the air. But, somehow neither Louis or I were frightened for more than one moment. The whole thing was so absorbingly interesting.
“ ‘That’s what I mean by its being outside my control,’ he said. ‘I said I was ready for any—any visitor to come in, and by God, we’ve got a beauty.’
“Now I was still, even in spite of the appearance of this shadow, quite convinced that I was only taking observations of a most curious case of disordered brain accompanied by the most vivid and remarkable thought-transference. I believed that I had not seen a slug-like shadow at all, but that Louis had visualised this dreadful creature so intensely that I saw what he saw. I found also that his spiritualistic trash-books which I thought a truer nomenclature than textbooks, mentioned this as a common form for Elementals to take. He on the other hand was more firmly convinced than ever that we were dealing not with a subjective but an objective phenomenon.
“For the next six months or so we sat constantly, but made no further progress, nor did the Thing or its shadow appear again, and I began to feel that we were really wasting time. Then it occurred to me, to get in a so-called medium, induce hypnotic sleep, and see if we could learn anything further. This we did, sitting as before round the dining-room table. The room was not quite dark, and I could see sufficiently clearly what happened.
“The medium, a young man, sat between Louis and myself, and without the slightest difficulty I put him into a light hypnotic sleep. Instantly there came a series of the most terrific raps, and across the table there slid something more palpable than a shadow, with a faint luminance about it, as if the surface of it was smouldering. At the moment the medium’s face became contorted to a mask of hellish terror; mouth and eyes were both open, and the eyes were focused on something close to him. The Thing waving its head came closer and closer to him, and reached out towards his throat. Then with a yell of panic, and warding off this horror with his hands, the medium sprang up, but It had already caught hold, and for the moment he could not get free. Then simultaneously Louis and I went to his aid, and my hands touched something cold and slimy. But pull as we could we could not get it away. There was no firm handhold to be taken; it was as if one tried to grasp slimy fur, and the touch of it was horrible, unclean, like a leper. Then, in a sort of despair,
