elaware Breakwater is situated just inside of Cape Henlopen, the southwestern point of land at the entrance of Delaware Bay, and was intended to form a harbor of refuge during storms for vessels passing along the coast. The work was commenced in 1829. It consists of two parts, the breakwater proper and the ice-breaker. The former is 1,203 yards long, extending in an E. S.E., and W. N.W. direction. The ice-breaker is designed to protect the harbor from floating ice brought down by the Delaware River, is 500 yards long, and lies in an E. by N. and W. by S. direction, having a passage of 350 yards between it and the breakwater, the prolongation of which would pass near the center of the ice-breaker. The work protects from the more dangerous winds an area of about 420 acres, having a depth of 3 to 6 fathoms, leaving a passage of about 1,000 yards in length between the shore and its landward extremity.

th, from the Corinthian to the Cenchrean Sea. The place was called the Diolcos, or drawing-place, and was five miles in length. This crossing-place was again used during the maritime warfare between the Genoese and the Turks. At a number of places in Lombardy and Venetia the locks are insufficient or absent, and boats are cradled and transported over the grade. The same thing takes place on the Morris and Essex Canal, which crosses the State of New Jersey, uniting the Hudson and Delaware Rivers. See inclined plane. In its simple form, the cradle consists of three longitudinal timbers united by ribs or cross-pieces. This is floated beneath the ship, which is lashed thereto by cables. The cradle and its burden are then floated to the inclined ways or slip, up which it is hauled, being supported by rollers which intervene between the timbers of the cradle and those of the slip. 6.

it, which, by means of a drum and chain, hauls up the cradle containing the boat. The lifts are worked by one attendant, who can raise or lower a boat from one level to another. There are two lock-chambers, over which is a lofty frame, having large wheels and chains, by which are suspended the cradles, into which the boats are floated when they are to be raised or lowered. See lift. On the Morris and Essex Canal, which crosses the State of New Jersey, connecting the Hudson and Delaware Rivers, there are, or were, 13 inclined planes, up which the canal-boats are hauled, the grades being thus ascended and descended without locking. The summit level at Stanhope is 900 feet above tide-water, and the changes of grade are sudden and frequent. A track of heavy rails is laid on the inclined plane, which has a grade of about 15°, and on this the cradle containing the boat ascends at the rate of five or six miles an hour. At the summit is the motor, consisting of a water-wheel, dri
