This is a very hard to find reprint of the 1882 book "The Military Telegraph During The Civil War In The United States" by William R. Plum. The original book was written in two volumes. This reprint contains both volumes and is about 760 pages. The book is in perfect condition. Read it, takes some notes, check out the maps and then go find those elusive threadless insulators. I would like to get back exactly what I paid for this information packed book. I bought it exactly six years ago for $100 and that`s what I`m offering it for today. I will pay the shipping, book rate.
