It consists of two parts—the con-denser, in which the exhaust steam of the main engineor engines is condensed, and the tower, in which theheated discharge from the condenser is cooled to a pro-per temperature to be used again for the further conden-sation of exhaust steam. The tower consists of a cylin-drical steel shell open at the top, supported upon a suit-able foundation, and having fitted at one side a fan, thefunction of which is to circulate a current of air throughthe tower and its tilling. This filling consists of layersof cylindrical tubular tiling, which rests upon a gratingsupported by a brick wall extending around the circum-ference of the tower. The heated discharge water. A SELF-COOLING JET CONDENSER. from the condenser enters the tower at the side, passesup the central pipe, is delivered on the upper layer oftiling and over the whole cross section of the tower by adistributing device consisting of four pipes, which arecaused to rotate about the central water pipe by thesimple reaction of the jets of heated water issuing fromone side of each pipe after the manner of a Barkersmill. The water thus delivered spreads over the outsideand inside surfaces of the walls of the tiling, and formsa continuous sheet, which is presented to the action ofthe air. The tiling, which is preferably six inches indiameter and twenty-four inches long, is placed on endin horizontal layers, one upon the other, and packed asclosely as possible, the walls of each individual tile ofeach successive layer being disposed so as to come oppo- site to the air spaces of the next lower layer, breakingjoints. • Assuming that each tile rests on only two others, agiven quantity of water,
