For forty years of his life, Buffon worked every morning at his desk from nine till two, and again in the evening from five till nine. His diligence was so continuous and so regular that it became habitual. His biographer has said of him, “Work was his necessity; his studies were the charm of his life; and towards the last term of his glorious career he frequently said that he still hoped to be able to consecrate to them a few more years.” He was a most conscientious worker, always studying to give the reader his best thoughts, expressed in the very best manner. He was never wearied with touching and retouching his compositions, so that his style may be pronounced almost perfect. He wrote the ‘Epoques de la Nature’ not fewer than eleven times before he was satisfied with it; although he had thought over the work about fifty years. He was a thorough man of business, most orderly in everything; and he was accustomed to say that genius without order lost three-fourths of its power. His great success as a writer was the result mainly of his painstaking labour and diligent application. “Buffon,” observed Madame Necker, “strongly persuaded that genius is the result of a profound attention directed to a particular subject, said that he was thoroughly wearied out when composing his first writings, but compelled himself to return to them and go over them carefully again, even when he thought he had already brought them to a certain degree of perfection; and that at length he found pleasure instead of weariness in this long and elaborate correction.” It ought also to be added that Buffon wrote and published all his great works while afflicted by one of the most painful diseases to which the human frame is subject. Literary life affords abundant illustrations of the same power of perseverance; and perhaps no career is more instructive, viewed in this light, than that of Sir Walter Scott. His admirable working qualities were trained in a lawyer’s office, where he pursued for many years a sort of drudgery scarcely above that of a copying clerk. His daily dull routine made his evenings, which were his own, all the more sweet; and he generally devoted them to reading and study. He himself attributed to his prosaic office discipline that habit of steady, sober diligence, in which mere literary men are so often found wanting. As a copying clerk he was allowed 3_d._ for every page containing a certain number of words; and he sometimes, by extra work, was able to copy as many as 120 pages in twenty-four hours, thus earning some 30_s._; out of which he would occasionally purchase an odd volume, otherwise beyond his means.
