\En`gi*neer"ing\, n.
Originally, the art of managing engines; in its modern and
extended sense, the art and science by which the mechanical
properties of matter are made useful to man in structures and
machines; the occupation and work of an engineer.
Note: In a comprehensive sense, engineering includes
      architecture as a mechanical art, in distinction from
      architecture as a fine art. It was formerly divided
      into military engineering, which is the art of
      designing and constructing offensive and defensive
      works, and civil engineering, in a broad sense, as
      relating to other kinds of public works, machinery,
      etc.
{Civil engineering}, in modern usage, is strictly the art of
   planning, laying out, and constructing fixed public works,
   such as railroads, highways, canals, aqueducts, water
   works, bridges, lighthouses, docks, embankments,
   breakwaters, dams, tunnels, etc.
{Mechanical engineering} relates to machinery, such as steam
   engines, machine tools, mill work, etc.
{Mining engineering} deals with the excavation and working of
   mines, and the extraction of metals from their ores, etc.
   Engineering is further divided into steam engineering, gas
   engineering, agricultural engineering, topographical
   engineering, electrical engineering, etc.
