The Pittsburgh Waste Book, so described on its cover, is the ledger of trader George Allen who had been appointed Indian Agent by the Commissioners for Indian Affairs in March of 1759, and is reputed to be the first known merchant's account book written in Pittsburgh. The book contains accounts and transactions taking place at Fort Pitt between June 19, 1759 and June 19, 1760. The ledger details the dates, goods, quantities, and prices for trading and also records names of traders. Native American trade was conducted either directly with tribes or through agents; some of the tribes represented in the book are Delaware, Shawnee, Mingo, Tawa (Ottawa), Wyandot (Huron or Wendat), Mohican, and others. In at least one instance goods were received of a "Shawannah Woman." Accompanying the Pittsburgh Waste Book is a folder containing twenty-six items of correspondence, mainly in the form of receipts for trade between 1757 and 1765. The various documents provide evidence of business conducted in Pittsburgh with payment to be received by the various traders or made to John Reynell, Treasurer for Indian Affairs in Philadelphia. The majority of the documents are handwritten though several are printed. The earliest document dates from 1757, a printed document presumably from a Philadelphia printing press, possibly Franklin and Hall, stating that Ellis Hughes should pay one pound, ten shillings, to John Reynell of Philadelphia. Another printed form, dated 1760, shows that Elizabeth Warner of Philadelphia lent the Commissioners for Indian Affairs one hundred fifty pounds. The form is signed by Commissioners Joseph Morris, William Fisher, William West, Thomas Willing, Joseph Richardson, Amos Strettell, Edward Penington, James Child, and John Reynell. Other receipts dictate the type of service provided such as "advice to the Indian Trade in Pittsburgh." There are also records indicating that provisions of food were taken by agents for the Province in Indian Affairs during expeditions, often explaining the length of the journey and rations for specific individuals. Lastly, the documents provide evidence of the Baynton Company's purchase of "the Commissioners for Indian Affairs, the Goods belonging to this Province, now at Pittsburgh ... " on March 15, 1765. The Philadelphia Company also known as Baynton, Wharton, and Morgan were simultaneously involved with increasing their trade with the Native Americans while disassociating themselves from English merchants due to legislation restraining colonial trade in the interest of the Crown. A number of names appear in this collection, aside from those mentioned above; a brief list follows: Joseph Wharton, John Hughes, Robert Field, E. E. Magee, Sanderson, Davenport, McMurray, Robert Tucknifs, Charles Kenny, Samuel Reyer, John Carson, Joseph Morris, Edward Pennington, Benedict Dorsey, Samuel Taylor, David Shields, James Irvine, Frederick Post, Robert Burchan, and others.
