A single letter came from him, posted at some outlandish place in the North-West. It was read to me by old Mrs Parker, but as Dick was a sad scribbler, its translation was not a very brilliant success. Nevertheless, from it I gathered how deep were his thoughts of me, and how eager he was to complete his work and return. Truly no man had a more devoted friend, and certainly no man was more in need of one. As the days grew warmer, and I sat ever with the _taedium vitae_ upon me, joyless and dispirited in that narrow world of darkness, I felt stifled, and longed for air. Essex Street is terribly close in July, therefore, finding the heat intolerable, I went forth at evening upon the Embankment with Mrs Parker, and, with my stick, practised walking alone upon that long, rather unfrequented stretch of pavement between the railings of the Temple Gardens and the corner of Savoy Street. Try to walk a dozen paces as one blind. Close your eyes, and tap lightly with your stick before you as you walk, and see how utterly helpless you feel, and how erratic are your footsteps. Then you will know how extremely difficult I found my first essays alone. I walked full of fear, as a child walks, stumbling, colliding, halting, and afterwards waiting for my pitying old woman-servant to take my arm and guide me in safety. Yet evening after evening I went forth and steadily persevered. I had, in the days before the world became shut out from my gaze, seen men who were blind guiding themselves fearlessly hither and thither among the London crowds, and I was determined, in Dick's absence, to master the means of visionless locomotion, so that I might walk alone for health's sake, if for nothing else. And so I continued, striving and striving. When Mrs Parker had served my dinner, cutting it up for me just as one places meat before a helpless infant, we went forth together, and for an hour each evening I went out upon that wide expanse of the Embankment pavement which formed my practice-ground. Gradually, by slow degrees, I became proficient in guiding myself with that constant tapping that marks a blind man's progress through the black void which constitutes his own narrow joyless world. At last, after several weeks of constant practice, I found to my great delight that I could actually walk alone the whole length of the pavement, guiding myself by intuition when encountering passers-by, and continuing straight on without stumbling or colliding with any object, a fact which gave me the utmost satisfaction, for it seemed to place me beyond, the need of a constant guide. With this progress I intended to astound Dick upon his return, and so gradually persevered towards proficiency. CHAPTER TWO. THE BRACELET AND THE PALM.
