The early nineteenth-century notebook of Elizabeth W. Supplee (probably of Philadelphia, Pennsylvania) contains handwritten math exercises demonstrating a variety of principles. The exercises include numerical problems, word problems, and other applications. The pages are adorned with elaborately scripted headings, Elizabeth’s name and initials, and simple sketches.

This trigonometry and surveying notebook belonged to Samuel M. Talley, who lived in Brandywine Hundred, near Wilmington, Delaware, in the nineteenth century. The notebook features mathematical problems and solutions related to the principles of trigonometry and the surveying of land. The latter part of the volume contains an account book listing wages due for farm labor.
