The house was, it may be remarked, of great antiquity, part of it being an old religious foundation of the 14th Century. The dugout was constructed at the base of a small bluff, and the sinking was through ordinary soft sandstone. The work was carried out by a local jobbing builder called Rolfe, assisted by a lad. Soon after the inception of his task he was annoyed by his candle being continually blown out by jets of sand, and, by similar jets hitting up against his own face. These phenomena he imagined to be due to some gaseous or electrical cause, but they reached such a point that his work was seriously hampered, and he complained to Mr. Jaques, who received the story with absolute incredulity. The persecution continued, however, and increased in intensity, taking the form now of actual blows from moving material, considerable objects, such as stones and bits of brick, flying past him and hitting the walls with a violent impact. Mr. Rolfe, still searching for a physical explanation, went to Mr. Hesketh, the Municipal Electrician of Folkestone, a man of high education and intelligence, who went out to the scene of the affair and saw enough to convince himself that the phenomena were perfectly genuine and inexplicable by ordinary laws. A Canadian soldier who was billeted upon Mr. Rolfe, heard an account of the happenings from his host, and after announcing his conviction that the latter had “bats in his belfry” proceeded to the dugout, where his experiences were so instant and so violent that he rushed out of the place in horror. The housekeeper at the Hall also was a witness of the movement of bricks when no human hands touched them. Mr. Jaques, whose incredulity had gradually thawed before all this evidence, went down to the dugout in the absence of everyone, and was departing from it when five stones rapped up against the door from the inside. He reopened the door and saw them lying there upon the floor. Sir William Barrett had meanwhile come down, but had seen nothing. His stay was a short one. I afterwards made four visits of about two hours each to the grotto, but got nothing direct, though I saw the new brickwork all chipped about by the blows which it had received. The forces appeared to have not the slightest interest in psychical research, for they never played up to an investigator, and yet their presence and action have been demonstrated to at least seven different observers, and, as I have said, they left their traces behind them, even to the extent of picking the flint stones out of the new cement which was to form the floor, and arranging them in tidy little piles. The obvious explanation that the boy was an adept at mischief had to be set aside in view of the fact that the phenomena occurred in his absence. One extra man of science wandered on to the scene for a moment, but as his explanation was that the movements occurred through the emanation of marsh gas, it did not advance matters much. The disturbances are still proceeding, and I have had a letter this very morning (February 21st, 1918) with fuller and later details from Mr. Hesketh, the Engineer. What is the real explanation of such a matter? I can only say that I have advised Mr. Jaques to dig into the bluff under which he is constructing his cellar. I made some investigation myself upon the top of it and convinced myself that the surface ground at that spot has at some time been disturbed to the depth of at least five feet. Something has, I should judge, been buried at some date, and it is probable that, as in the case cited in the text, there is a connection between this and the disturbances. It is very probable that Mr. Rolfe is, unknown to himself, a physical medium, and that when he was in the confined space of the cellar he turned it into a cabinet in which his magnetic powers could accumulate and be available for use.
