Dietzgen Pocket Compass

Dietzgen termed this an improved type of foresters' and geologists' compass, as made for the U.S. Forest Service. This example is marked "DIETZGEN 17252." It has a nickel-silver base, aluminum box, and brass sights. The raised rim and beveled outer ring are graduated every degree and numbered every 10 degrees in quadrants, and adjustable for variation. The western half of the face is graduated to degrees, and equipped with a pendulum clinometer pivoted at the center. A circular level vial is at NE. The four beveled edges of the plate are graduated, one to inches and tenths, one to inches and eights, and two as protractors. There is a ball and socket joint for mounting on a Jacob staff. The leather case is marked "DIETZGEN" and "CCC," the latter referring to the Civilian Conservation Corps. The University of Missouri at Columbia donated this compass to the Smithsonian.
