Daniel Conover composed this mathematics exercise book containing definitions, problems, solved examples, rules, cases, and remarks. Subjects covered include practical geometry, mensuration of superficies, conic sections, mensuration of solids, and cylindrical rings.

Daniel Conover composed this mathematics exercise book containing definitions, problems, solved examples, rules, cases, and remarks. Subjects covered include practical geometry, mensuration of superficies, conic sections, mensuration of solids, and cylindrical rings. Short sections relate to the application of the principles to the work of artificers, bricklayers, masons, carpenters and joiners, slaters and tilers, plasterers, painters and glaziers, pavers, as well as the construction of roofs and measuring timber. Conover illustrated examples of geometric shapes and angles, some painted with watercolors. A watercolor painting of a building also appears in the volume.

This volume contains an introduction to land surveying and its underlying mathematical principles. Included are practical problems, illustrated examples, and reference tables.

This volume (174 pages) contains an introduction to land surveying and its underlying mathematical principles. Included are practical problems, illustrated examples, and reference tables.

The book, entitled "Land Surveying," opens with an introduction to geometry and trigonometry then focuses on practical surveying applications (around p. 49). Definitions, theorems, and problems are illustrated with diagrams and example problems. The remainder of the volume (pp. 142-174) pertains to surveying measurements, methodology, and tools. The author explained different measurements, such as Scottish units, English units, and the "chain," and applied mathematical principles to surveyors' practices. Many problems include ink-and-watercolor pictures of irregularly shaped lakes or fields, and several concern locations referred to as "Broom Park," "Mire Park," "Farm Park," and "Hill Side Farm." Additional subjects of study are land division and measuring levelness. The volume also contains tables of measurements. Decorative geometric drawings, done in ink with the occasional addition of watercolors, are interspersed throughout the book.

One letter written by Harry [Crockett?] to his mother, Mrs. L. F. Crockett, from Portland, Maine, on October 8, 1903, is laid into the volume. Written on John W. Perkins Company, Wholesale Druggists, illustrated stationery, the letter comments on family matters, business, and deaths of acquaintances, including one gentleman who was killed by an electric car.
