In the summer of 1762 Franklin wound up his business in England as agent
for the Pennsylvania Assembly and returned to Philadelphia. William
Franklin was married in London and soon followed his father to take
office as royal governor of New Jersey. Before sailing, Franklin wrote a
long letter to Giambatista Beccaria in Turin describing his invention of
a new musical instrument, the glass harmonica, which for a generation or
so enjoyed great popularity in Europe. Both Mozart and Beethoven wrote
compositions for it. In America once more, Franklin devoted much of his
to his duties as join deputy postmaster general, going on long
inspection trips to all the offices from Virginia to New Hampshire. His
correspondence with friends made in England shows some nostalgia for his
life there, but letters from them at least brought the political news
and gossip of London, where he had spent five busy and interesting
years.Mr. Labaree is Farnam Professor Emeritus of History at Yale
