Compass, staff, and chain used by Lincoln while deputy surveyor of Sangamon County. The instruments were manufactured by Rittenhouse and Company of Philadelphia, Pennsylvania in the late 1700s.
Although not Lincoln's, the surveying books by Abel Flint and Robert Gibson and the saddlebags are like ones he used. Leather saddlebags could carry notebooks, equipment, and provisions for a day's travel on horseback. |
