So there is an outlook for every mood, and I doubt not that this ingenious provision contributes potently towards promoting bibliomaniac harmony and prosperity in my friend's household. It is true that I myself am not susceptible to external influences when once I am surrounded by books; I do not care a fig whether my library overlooks a garden or a desert; give me my dear companions in their dress of leather, cloth, or boards, and it matters not to me whether God sends storm or sunshine, flowers or hail, light or darkness, noise or calm. Yet I know and admit that environment means much to most people, and I do most heartily applaud Dr. O'Rell's versatile device. I have always thought that De Quincey's workshop would have given me great delight. The particular thing that excited De Quincey's choler was interference with his books and manuscripts, which he piled atop of one another upon the floor and over his desk, until at last there would be but a narrow little pathway from the desk to the fireplace and from the fireplace to the door; and his writing-table--gracious! what a Pelion upon Ossa of confusion it must have been! Yet De Quincey insisted that he knew "just where everything was," and he merely exacted that the servants attempt no such vandalism as "cleaning up" in his workshop. Of course there would presently come a time when there was no more room on the table and when the little pathway to the fireplace and the door would be no longer visible; then, with a sigh, De Quincey would lock the door of that room and betake himself to other quarters, which in turn would eventually become quite as littered up, cluttered up, and impassable as the first rooms. From all that can be gathered upon the subject it would appear that De Quincey was careless in his treatment of books; I have read somewhere (but I forget where) that he used his forefinger as a paper-cutter and that he did not hesitate to mutilate old folios which he borrowed. But he was extraordinarily tender with his manuscripts; and he was wont to carry in his pockets a soft brush with which he used to dust off his manuscripts most carefully before handing them to the publisher. Sir Walter Scott was similarly careful with his books, and he used, for purposes of dusting them, the end of a fox's tail set in a handle of silver. Scott, was, however, particular and systematic in the arrangement of his books, and his work-room, with its choice bric-a-brac and its interesting collection of pictures and framed letters, was a veritable paradise to the visiting book-lover and curio-lover. He was as fond of early rising as Francis Jeffrey was averse to it, and both these eminent men were strongly attached to animal pets. Jeffrey particularly affected an aged and garrulous parrot and an equally disreputable little dog. Scott was so stanch a friend of dogs that wherever he went he was accompanied by one or two--sometimes by a whole kennel--of these faithful brutes.
