Astronomy. Determination of time, longitude, latitude, and azimuth
A U.S. Coast and Geodetic Survey field manual on positional astronomy, written by William Bowie and printed by the Government Printing Office in Washington in 1913 for surveyors computing time, longitude, latitude, and azimuth. Halftone photographs show brass transit instruments on cast bases and a portable clapboard observing shed beside the Capitol dome, useful for instrument silhouettes and period technical texture.
