notes: label: Description
content: This dumpy level is one of six identical instruments that the Interstate Commerce Commission of New Jersey ordered in July 1914, each to be engraved "INTERSTATE COMMERCE COMMISSION." C. L. Berger & Sons termed it an instrument "of great precision, superior to any Wye Level of same aperture, power of telescope, and same sensitiveness of spirit level." Berger went on to say that it was the "best instrument for use in distant lands and rough country on account of its great compactness, simplicity, strength to withstand rough treatment, permanency of adjustment, and steadiness in strong wind, requiring but ordinary attention and care to keep in working order." New, it cost $100 (or $113 with fixed stadia wires). The inscription reads "C. L. Berger & Sons, Boston 10316."
