Buffon caused his "Époques de la Nature" to be copied eighteen times, so many corrections and changes were made. As he was then (1778) over seventy years of age, one would think this an evidence that his mind was failing him. Pope covered with memoranda every scrap of clear paper which came in his way. Some of his most elaborate literary work was begun and finished on the backs of old letters and bits of yellow wrappers. We do not wonder that such fragmentary manuscript always suggested the idea of revision and correction. It is difficult to understand why Pope should have assumed this small virtue of economy and yet often have been lavish in other directions; indeed, it may be questioned whether it was intended to be an act of economy. Such petty parsimony is inexplicable, but certainly it grew into a fixed habit with him. We believe it was Swift who first called him "paper-saving Pope;" but Swift was nearly as eccentric a paper-saver as Pope. He wrote to Dr. Sheridan: "Keep very regular accounts, in large books and a fair hand; not like me, who, to save paper, confuse everything!" Miss Mitford had the same habit of writing upon waste scraps of paper, fly-leaves of books, envelopes, and odd rejected bits, all in so small a hand as to be nearly illegible. William Hazlitt was also remarkable for the same practice, and we are told that he even made the first outline of some of his essays on the walls of his chamber, much to the annoyance of his landlady. Some idea of the rapidity with which Byron wrote may be inferred from the fact that the "Prisoner of Chillon" was written in two days and sent away complete to the printer. The traveller in Switzerland does not fail to visit the house--once a wayside inn, at Merges, on the Lake of Geneva--where Byron wrote this poem while detained by a rainstorm, in 1816. On the heights close at hand is the Castle of Wuffens, dating back to the tenth century. Morges is a couple of leagues from Lausanne, and the spot where Gibbon finished his "Rise and Fall of the Roman Empire," in 1787. Colton, the philosophical but erratic author of "Lacon," wrote that entire volume upon covers of letters and such small scraps of paper as happened to be at hand when a happy thought inspired him. Having completed a sentence, and rounded it to suit his fancy, he threw it into a pile with hundreds of others, which were finally turned over to the printer in a cloth bag. No classification or system of arrangement was observed. Colton exhibited all the singularities that only too often characterize genius, especially as regards improvidence and recklessness of habit. He lived unattended, in a single room in Princes Street, Soho, London, in a neglected apartment containing scarcely any furniture. He wrote very illegibly upon a rough deal table with a stumpy pen. He was finally so pressed with debts that he absconded to avoid his London creditors, though he held the very comfortable vicarage of Kew, in Surrey.
