GREENWAY BREAKWATER.

A most ingenious invention, says the Liverpool Journal of Commerce, called the Greenwood Breakwater, Ima come before our notice, and is one, which, if we can judge froin the successful experiments made;' will in a very short timobe brought prominently before the public, The object of the breakwater, which is simply a line of buoys, is not to resist the force of the waves, but to turn them against one another. The buoys are moored in a straightline independantof one another and are of a triangular shape, with a sharp point which is directed towards the sea when the buoy is in position. They are held by two anchors to each buoy, lore and aft, so as to keep them in position with the space of a buoy between each. The draught of each buoy is ten feet. When a wave strikes the sharp prow of a buoy, it is divided into two parts; the divided wave then rushes towards the buoys on either side and in the space between it meets that portion of another wave which has had similar treatment from the neighboring buoy with the result that the diversion and collision reduce, or entirely break the force of the wave, and the water is carried harmlessly inside of the breakwater. Such a breakwater could be constructed in a very short space of time, while the cost, compared with that of a concrete or stone breakwaters) would ho trifling.
