Inquiry has failed to elicit who this Seaton may have been. I may add that the visit of the deceased to Allerton's Farm, and the general nature of the alarm there, apart from his particular explanation, have been absolutely established. With this foreword I append his account exactly as he left it. It is in the form of a diary, some entries in which have been expanded, while a few have been erased. April 17.--Already I feel the benefit of this wonderful upland air. The farm of the Allertons lies fourteen hundred and twenty feet above sea-level, so it may well be a bracing climate. Beyond the usual morning cough I have very little discomfort, and, what with the fresh milk and the home-grown mutton, I have every chance of putting on weight. I think Saunderson will be pleased. The two Miss Allertons are charmingly quaint and kind, two dear little hard-working old maids, who are ready to lavish all the heart which might have gone out to husband and to children upon an invalid stranger. Truly, the old maid is a most useful person, one of the reserve forces of the community. They talk of the superfluous woman, but what would the poor superfluous man do without her kindly presence? By the way, in their simplicity they very quickly let out the reason why Saunderson recommended their farm. The Professor rose from the ranks himself, and I believe that in his youth he was not above scaring crows in these very fields. It is a most lonely spot, and the walks are picturesque in the extreme. The farm consists of grazing land lying at the bottom of an irregular valley. On each side are the fantastic limestone hills, formed of rock so soft that you can break it away with your hands. All this country is hollow. Could you strike it with some gigantic hammer it would boom like a drum, or possibly cave in altogether and expose some huge subterranean sea. A great sea there must surely be, for on all sides the streams run into the mountain itself, never to reappear. There are gaps everywhere amid the rocks, and when you pass through them you find yourself in great caverns, which wind down into the bowels of the earth. I have a small bicycle lamp, and it is a perpetual joy to me to carry it into these weird solitudes, and to see the wonderful silver and black effect when I throw its light upon the stalactites which drape the lofty roofs. Shut off the lamp, and you are in the blackest darkness. Turn it on, and it is a scene from the Arabian Nights.
