This collection consists of a manuscript schoolbook and 4 daybooks. The Schoolbook (145 pages) contains 118 pages of notes and example problems concerning mathematics, business finance, and surveying, dated at East Hampton, New York, from March 1815-March 1818. Many of the geometrical and surveying problems are illustrated, and financial problems pertain to subjects such as European currencies and calculation of interest. The schoolbook also includes a copied poem. The final 27 pages provide examples of a daybook (January 1, 1819-January 31, 1819, 11 pages) and double-entry ledger (January 1, 1819-May 29, 1819, 16 pages). The same accounts are represented in each of these sections, and most pertain to sales of foodstuffs and fabrics.

He sold foodstuffs such as butter, spices, and tea; household goods such as brooms and nails; clothing and fabrics such as calico; and other items, such as tobacco and soap.
