An early reprint of this American telegraphy manual, first published in 1865. Despite its evident popularity in reaching a fifth edition in seven years, early editions are scarce institutionally, with no copies of this fifth edition in Worldcat, which lists 2 copies of the sixth edition printed the same year, in NYPL and Lehigh University.
