I'm not really sure what to make of today's bookmark. It's a disbound portion of an unknown German language book, no mention of the publisher or date. There is this note written in pen:

Made and printed at Ephrata Monastery just before the Battle of Brandywine. Most of the edition was use for gun wad at Brandywine
Given to Chas. L. Hamilton and Kay Phillips, 1900 September while at monastery.  

I've supplied some links to information on Brandywine and Ephrata. A fascinating bit of history if authentic.

Found in "The Agrarian Crusade" by Solon Buck. Published by Yale University Press, 1920.
