When travelling, I have now and then watched the sunrise, and always with an exultation unlike anything produced in me by other aspects of nature. I remember daybreak on the Mediterranean; the shapes of islands growing in hue after hue of tenderest light, until they floated amid a sea of glory. And among the mountains--that crowning height, one moment a cold pallor, the next soft-glowing under the touch of the rosy-fingered goddess. These are the things I shall never see again; things, indeed, so perfect in memory that I should dread to blur them by a newer experience. My senses are so much duller; they do not show me what once they did. How far away is that school-boy time, when I found a pleasure in getting up and escaping from the dormitory whilst all the others were still asleep. My purpose was innocent enough; I got up early only to do my lessons. I can see the long school-room, lighted by the early sun; I can smell the school-room odour--a blend of books and slates and wall-maps and I know not what. It was a mental peculiarity of mine that at five o'clock in the morning I could apply myself with gusto to mathematics, a subject loathsome to me at any other time of the day. Opening the book at some section which was wont to scare me, I used to say to myself: "Come now, I'm going to tackle this this morning! If other boys can understand it, why shouldn't I?" And in a measure I succeeded. In a measure only; there was always a limit at which my powers failed me, strive as I would.
