This suggestion was successfully carried out in France, in the presence of the king, at the county-seat of the Duke D’Ayen; and afterwards Buffon, D’Alibard, and Du Lor confirmed it by experiments of their own. But they did not use steeples; they erected lofty iron rods, in one instance ninety-nine feet high. Nevertheless, it was in effect the same method that Franklin had suggested. The experiment was repeated in various forms in England, and the Philadelphia philosopher, postmaster, and author of “Poor Richard” became instantly famous as the discoverer of the identity of lightning with electricity. Two years before these experiments were inaugurated he had retired from business for various reasons, chief among which was his strong desire to devote more time to science. His letters continue to be filled with closely reasoned details of all sorts of experiments. So earnest were these Philadelphia investigators, that when Kinnersley wrote complaining that in travelling to Boston he found difficulty in keeping up his experiments, Franklin, in reply, suggested a portable electrical apparatus which would not break on a journey. In a letter written to Collinson on October 19, 1752, Franklin says he had heard of the success in France of the experiment he had suggested for drawing the lightning from clouds by means of an elevated metal rod; but in the mean time he had contrived another method for accomplishing the same result without the aid of a steeple or lofty iron rod. This was the kite experiment of which we have heard so much, and he goes on to describe it:
