The first page of Samuel’s diary for 1864 contains this entry:

Sam J. Melvin, Co. A, 100th Penna Vols
“Should I chance to fall in battle, or meet with any other sad misfortune, the finder of this little book will confer great favor upon my friend by sending it, with my watch, pocket book, bible, and other little articles to William Melvin, Eldersville, Washington Co. Penna, using whatever money or postage stamps that may be found with them to defray expense.”
