Gurley Manual 1874
American Engineer's & Surveyor's Instruments
By W. & L. E. Gurley

The manuals
published by W. & L.E. Gurley, one of America’s leading producers
of mathematical and scientific instruments, have been used by generations
of engineers and surveyors. In this manual Gurley describes all
of its various instruments: how they are calibrated, used and maintained,
and includes a catalog of its complete instrument line. This 1874
edition is especially valuable since it is one of the earliest and
is rarely found. With an introduction by David C. Garcelon.
