Apparently a complete basic course in trigonometry and land surveying. Cursive handwriting is neat and text and geometric figures are laid out in a careful and aesthetic pleasing manner. An interesting example of early nineteenth-century educational practice. Provenance: part of a group of materials from a local estate with ancestral family connections to the Rogers of Highlands, Maryland (other addresses include Marriottsville and Forest View).
