from The Century Dictionary and Cyclopedia
- n. A device for the propulsion of vessels consisting of a jet of water expelled forcibly from the stern.
- n. A boring-apparatus using a jet of water from a nozle at high velocity, for excavating holes in soft earth or removing soil from the face of a bluff or bank. The flowing water erodes the loosened earth, and the latter flows away as silt suspended in the water. Used in hydraulic mining. When used for boring vertical holes it may also be called a wash-drill (which see).
