The 8½"x14" document in the booklet is an agreement that John Johnson is giving Jacob Laudenslager the sole right to have full rights to the process in Marlboro Township in Starke County, Ohio and a John Bentz is acquiring an interest for $5.00 and also will be allowed to use the process to tan his own hides at his home. This document, signed on February 14, 1866 also has a federal revenue stamp on the right side of the document. The booklet contains the process for tanning a variety of skins. There is text and sketches of various animals. In addition to the booklet, there are two separate pages, one giving the recipe for soaking, taming, suds, sulfuric acid and borax. These pages, due to their appearance look to be more recent.
