Franklin was a man who was never so busy about many things that he did not have time for another. You have been told how he acquired a good English style; to this was added the charm that he always had something to say that was worth hearing. He was fond of different branches of science and was gifted with inventive talent. He studied the laws which govern the movement of hot air, and invented what is called an “open fireplace stove;” under the name of “the Franklin stove” or “Pennsylvania fireplace,” a modified form of it is still in use. When he was about forty years old, Franklin became interested in the subject of electricity and became convinced that lightning is a manifestation of electricity. He proved this by a famous experiment, drawing the current down the string of a kite in a storm. He invented the lightning rod--for he was always trying to apply the principles of science so as to make them useful. Among his other inventions, was a musical instrument called the “Armonica,” a kind of musical glasses. Franklin was a progressive and public-spirited citizen. He organized an orderly night-watch for Philadelphia, established the first volunteer fire company, the first hospital, and the first subscription and circulating library, in America. He interested people in the subject of education and established an academy which became the College of Philadelphia, and was the real origin of the University of Pennsylvania. He originated also the American Philosophical Society “to propagate useful knowledge.” For years he served as postmaster, first of Philadelphia, and afterwards as deputy postmaster-general of the colonies; he introduced many reforms in the postal service and improved the methods of carrying mail to and from the seventy post offices then in the country. Franklin was now nearly fifty years of age and he was just to begin the career which made him honored and renowned. This was his work as a patriot at home and abroad. When the French and Indian War broke out, he was commissioned to procure wagons for Braddock’s army. In two weeks by the exercise of private means and wonderful energy, he procured one hundred and fifty wagons and two hundred and fifty pack-horses. After Braddock’s defeat, Franklin, with a band of men whom he had persuaded to enlist, went to protect the settlers on the frontier against the Indians.
