Today’s digital feature is the Martha Ryan Cipher Book, SHC collection #1940-z. From the finding aid:
“School mathematics exercise book kept by Martha Ryan, probably of Perquimans County, N.C., circa 1781. The volume is bound in homespun fabric with ornate decorations on each page. Mottos, ship designs, and other patriotic decorations, and inscriptions such as “Liberty” or “George Washington” on many of the pages reflect the Revolutionary influence.”
