Mr. Fortescue's character was as enigmatic as his history was obscure. He seemed to be destitute both of kinsfolk and friends, never made any allusion to his family, neither noticed women nor discussed them. Politics and religion he equally ignored, and, so far as might appear, had neither foibles nor fads. On the other hand, he had three passions--science, horses, and horticulture, and his knowledge was almost encyclopædic. He was a great reader, master of many languages, and seemed to have been everywhere and seen all in the world that was worth seeing. His wealth appeared to be unlimited, but how he made it or where he kept it I had no idea. All I knew was that whenever money was wanted it was forthcoming, and that he signed a check for ten pounds and ten thousand with equal indifference. As he conducted his private correspondence himself, my position as secretary gave me no insight into his affairs. My duties consisted chiefly in corresponding with tradesmen, horse-dealers, and nursery gardeners, and noting the results of chemical experiments. Mr. Fortescue was very abstemious, and took great care of his health, and if he was really verging on eighty (which I very much doubted), I thought he might not improbably live to be a hundred and ten and even a hundred and twenty. He drank nothing, whatever, neither tea, coffee, cocoa, nor any other beverage, neither water nor wine, always quenching his thirst with fruit, of which he ate largely. So far as I knew, the only liquid that ever passed his lips was an occasional liquor-glass of a mysterious decoction which he prepared himself and kept always under lock and key. His breakfast, which he took every morning at seven, consisted of bread and fruit. He ate very little animal food, limiting himself for the most part to fish and fowl, and invariably spent eight or nine hours of the twenty-four in bed. We often discussed physiology, therapeutics, and kindred subjects, of which his knowledge was so extensive as to make me suspect that some time in his life he had belonged to the medical profession. "The best physicians I ever met," he once observed, "are the Callavayas of the Andes--if the preservation and prolongation of human life is the test of medical skill. Among the Callavayas the period of youth is thirty years; a man is not held to be a man until he reaches fifty, and he only begins to be old at a hundred." "Was it among the Callavayas that you learned the secret of long life, Mr. Fortescue?" I asked. "Perhaps," he answered, with one of his peculiar smiles; and then he started me by saying that he would never be a "lean and slippered pantaloon." When health and strength failed him he should cease to live. "You surely don't mean that you will commit suicide?" I exclaimed, in dismay. "You may call it what you like. I shall do as the Fiji Islanders and some tribes of Indians do, in similar circumstances--retire to a corner and still the beatings of my heart by an effort of will."
