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; 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 gauge 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.
