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; 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.
