A small boat has recently been constructed at Richmond, Va., which is propelled by a propeller, called the " submerged or scull propeller." The power is applied to the stern of the boat, and operates in the manner of a fish tail waving from side to side, to give the impetus. On each side of the boat there is an upright lever, between which the operator sits, and by working the levers backwards and forwards, the motion is j iven to the fishtail and to the boat. The boat is about nine feet long and three wide, and the speed, with one man in it, about four miles an hour.
