But it is folly to linger over the limitations of the tallow-chandler's son. The catalogue of his beneficent activity is a vast one. Balzac once characterized him as the man who invented the lightning-rod, the hoax, and the republic. His contributions to science have to do with electricity, earthquakes, geology, meteorology, physics, chemistry, astronomy, mathematics, navigation of air and water, agriculture, medicine, and hygiene. In some of these fields he did pioneer work of lasting significance. His teachings of thrift and prudence, as formulated in the maxims of Poor Richard, gave him a world-wide reputation. He attacked war, like Voltaire, not so much for its wickedness as for its folly, and cheerfully gave up many years of a long life to the effort to promote a better understanding among the nations of the world. It is perhaps needless to add what all persons who love good writing know, that Benjamin Franklin was a most delightful writer. His letters cover an amusing and extraordinary variety of topics. He ranges from balloons to summer hats, and from the advantages of deep ploughing to bifocal glasses, which, by the way, he invented. He argues for sharp razors and cold baths, and for fresh air in the sleeping-room. He discusses the morals of the game of chess, the art of swimming, the evils of smoky chimneys, the need of reformed spelling. Indeed, his passion for improvement led him not only to try his hand upon an abridgment of the Book of Common Prayer, but to go even so far as to propose seriously a new rendering of the Lord's Prayer. His famous proposal for a new version of the Bible, however, which Matthew Arnold solemnly held up to reprobation, was only a joke which Matthew Arnold did not see--the new version of Job being, in fact, a clever bit of political satire against party leadership in England. Even more brilliant examples of his skill in political satire are his imaginary Edict of the King of Prussia against England, and his famous Rules for Reducing a Great Empire to a Small One. But I must not try to call the roll of all the good things in Franklin's ten volumes. I will simply say that those who know Franklin only in his Autobiography, charming as that classic production is, have made but an imperfect acquaintance with the range, the vitality, the vigor of this admirable craftsman who chose a style "smooth, clear, and short," and made it serve every purpose of his versatile and beneficent mind.
