The inquiring mind of Franklin did not rest with experiments in the heavens. As a wealthy and independent citizen of Philadelphia he interested himself in all matters of public improvement. He founded a philosophical society to spread useful knowledge of all kinds. He laid the foundation of what is now the University of Pennsylvania, and secured a charter from George II.; but he had little sympathy with the teaching of dead languages, attaching much more importance to the knowledge of French and Spanish than of Latin and Greek. We see in all his public improvements the utilitarian spirit which has marked the genius of this country, but a spirit directed into philanthropic channels. Hence he secured funds to build a hospital, which has grown into one of the largest in the United States. He established the first fire company in Philadelphia, as well as the first fire insurance company; he induced the citizens of Philadelphia to pave and sweep their streets, which were almost impassable in rainy weather; he reorganized the night-watch of the town; he improved the street-lighting; he was the trustee of a society to aid German immigrants; he started a volunteer military organization for defence of the State against the Indians; he made a new fertilizer for the use of farmers; he invented the open "Franklin stove" to save heat and remedy the intolerable smoky chimneys which the large flues of the time made very common; he introduced into Pennsylvania the culture of the vine; in short, he was always on the alert to improve the material condition of the people. Nor did he neglect their intellectual improvement, inciting them to the formation of debating societies, and founding libraries. His intent, however, was avowedly utilitarian, to "supply the vulgar wants of mankind," which he placed above any form of spiritual philosophy,--inculcating always the worldly expediency of good character and the poor economy of vice. Herein he agreed with Macaulay's idea of progress as brought out in his essay on Lord Bacon. He never soared beyond this theory in his views of life and duty. The Puritanic idea of spiritual loftiness he never reached and never appreciated. But it was not as a public-spirited citizen, nor as a successful man of business, nor even as a scientific investigator, that Franklin earned his permanent fame. In each of these respects he has been surpassed by men of whom little is known. These activities might have elevated him into notice and distinction, but would not have made him an immortal benefactor to his country. It was his services as a diplomatist and a political oracle, united with his patriotism and wisdom, that gave to him his extraordinary prominence in American history.
