FIELD WORK IN CIVIL ENGINEERING.
The outfit of field instruments contains compasses, transits, and levels
of various approved makes; a solar transit, furnished also with stadia wires
and gradienter for tachymetric work; a Gurley mining transit, one of the
finest products of the instrument maker's art; a complete Gurley transit,
graduated to 30 seconds, with solar attachment, recently added; hand-levels
and clinometers for field topography; plane tables; a sextant; together
with an adequate supply of leveling rods, telemeter rods, signal poles, chains,
tapes, pins, and so on. For hydraulic surveys a hook guage and a current
meter are provided. All students are instructed in the theory and adjustments
of the field instruments and in their practical use in the field. They
are also required to make up their field-books in standard forms; to reduce
their surveys and execute all the necessary profiles, plans, and maps; and
to determine lengths, areas, and volumes both from the maps and from the
original notes. Polar planimeters are provided for facilitating such estimates,
and a pantograph for making reduced copies of finished drawings.
