This collection is made up of incoming letters and legal memorandums to William F. Joy of Boston, Massachusetts. His correspondents primarily discussed oil and real estate in and near Stryker, Ohio. William F. Joy received around 34 letters from January 4, 1865-July 27, 1866, primarily related to the area around Stryker, Ohio. Joy's correspondents, who included Converse L. Chase, C. Blinn, and C. S. Tuttle, reported on the progress of oil wells in the area and on competing prospectors. Chase, a lumber dealer, also commented on the cost of lumber. Some correspondents mentioned a mineral spring in the area, and the collection includes 3 small printed reports about an analysis of the spring by University of Michigan professor Silas H. Douglas (February 1870). Other letters, and 2 memorandums related to legal agreements, concern the ownership of property in Williams County, Ohio, and Crawford County, Ohio. One undated document is an inventory of mill machinery, and another is a printed prospectus for the Rocky River Oil Company in eastern Ohio.
