Well, it is not for him that I write; there are books and books, and even chapters and chapters, just as there are people and people. I myself avoid books dealing with health and disease. I used when younger to be unable to resist the temptation of a medical book; but now I am wiser, and if I sometimes yield to the temptation, it is with a backward glancing eye and a cautious step. And I will say that I generally put back the book with a snap, in a moment, as though a snake had stung me. But there will be no pathology here—nothing but a patient effort to look a failing in the face, and to suggest a remedy. [Sidenote: FEARS] I speak to the initiated, to those who have gone down into the dark cave, and seen the fire burn low in the shrine, and watched aghast the formless, mouldering things—hideous implements are they, or mere weapons?—that hang upon the walls. Do you know what it is to dwell, perhaps for days together, under the shadow of a fear? Perhaps a definite fear—a fear of poverty, or a fear of obloquy, or a fear of harshness, or a fear of pain, or a fear of disease—or, worse than all, a boding, misshapen, sullen dread which has no definite cause, and is therefore the harder to resist. [Sidenote: DREAMS] These moods, I say it with gratitude for myself and for the encouragement of others, tend to diminish in acuteness and in frequency as I grow older. They are now, as ever, preluded by dreams of a singular kind, dreams of rapid and confused action, dreams of a romantic and exaggerated pictorial character—huge mountain ranges, lofty and venerable buildings, landscapes of incredible beauty, gardens of unimaginable luxuriance, which pass with incredible rapidity before the mind. I will indicate two of these in detail. I was in a vessel like a yacht, armed with a massive steel prow like a ram, which moved in some aerial fashion over a landscape, skimming it seemed to me but a few feet above the ground. A tall man of benignant aspect stood upon the bridge, and directed the operations of the unseen navigator. We ascended a heathery valley, and presently encountered snow-drifts, upon which the vessel seemed to settle down to her full speed; at last we entered a prodigious snowfield, with vast ridged snow-waves extending in every direction for miles; the vessel ran not over but through these waves, sending up huge spouts of snow which fell in cool showers upon my head and hands, while the tinkle of dry ice fragments made a perpetual low music. At last we stopped and I descended on to the plateau. Far ahead, through rolling clouds, I saw the black snow-crowned heights of a mountain, loftier than any seen by human eye, and for leagues round me lay the interminable waste of snow. I was aroused from my absorption by a voice behind me; the vessel started again on her course with a leap like a porpoise, and though I screamed aloud to stop her, I saw her, in a few seconds, many yards ahead, describing
