Submarine telegraphs their history, construction, and working. Founded in part on Wunschendorff's 'Traite de tele graphie sous-marine' This book, "Submarine telegraphs their history, construction, and working", by Charles Bright, is a replication of a book originally published before 1898. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible. This book was created using print-on-demand technology. Thank you for supporting classic literature.
