dredge boat

A form of dredging-machine in which the boat becomes its own grubber, the depth at which the mud-fan shall operate being regulated by introduction of water into compartments of the ve el. The dredger may operate by plowing a channel through a sand or mud-bar, the latter presumably, as it has been constructed to keep open the mouths of the Mi i ippi, allowing the current to carry off the loosened matter. A scoop is, however, to be rigged forward to plow into the mud, when the dredger will back off with its load, carry it out to sea, and dump it. ( Knight.) = dried drědge (2), s . [O.
