George Hannum notebook
Manuscripts
The manuscript is titled: A Compendious System of Practical Surveying taken from the latest Author by George Hannum, Philomath, and Taught by John Day, Preceptor. This fragile volume consists of approximately 54 pages of written text and diagrams. This is an advance work of surveying showing how to undertake the solution of complex problems. The manuscript opens with geometrical problems and moves on to right angle and oblique trigonometry. The text then shifts to finding areas of various shapes using logarithms. Also recorded are various methods of mapping and how to draw maps, ad methods of completing surveys for the division of land. It is in this section that Hannum applies colors to the illustrations of some of the surveys. There are two complete surveys and they are segregated in the text by being placed, inverted, on the last blank pages of the manuscript. From Birmingham Township, Pennsylvania.
