 IT WILL GET UP HILL.

 The St. Paul (Minn.) Press says :-
 During the winter months Prof. Saroni hes been busy in psrfecting his steam wagon, and he has forwarded his model of the machinery to Washington, D. O., for the purpose of securing letters patent upon it, he having so far been operat- ing under 8 simple caveat. Since the appearance of the apparatus upon the streets last fall it has been vastly inn proved. By 8 double system of clutches and pulleys; one at each end of the driving shaft, the power can be applied for speed or for slow work with heavy draught. But the greatest novelty thet has been introduced into the inacbinery is system of propulsion for use in case of ascending steep hill. Taking an idea from the fact that horse can draw a much heavier load than it's own weight, the inventor has introduced two sets of levers that correspond exactly in move- ment and in the application of power with the two hind legs of horse, the one alternating with the other, precisely as do the limbs of the animal. It is difficult, without diagrams, to illustrate how this is accomplished, but it's effect can be understood with sufficient clear ness for the foregoing comparison. The second important advance made is in 8 device for the rapid generation of steam, which is marvel of ingenuity, as we'll as a marvel of success. AS formerly, gasoline is the fuel employed, and the flame is made to play upon pumice- stone, which heats to whiteness, and thus not only creates reservoir of con- stant heat, but should the fs-- be tenn porarily extinguished by sudden jerk of the machinery, as it is apt to be, it is instantly rekindled. The pumice-stone occupies the fire-box, above which are arranged coils of pipe containing the water, which are so arranged as to give the water both lateral and longitudinal motion, and to permit the sediment to settle in the lower pipes on the side of the fre.box, where it can be readily taken out. A second and smaller boiler is used to generate steam first, and this super heated steam is conducted to a nozzle, at the end of which and below it is placed closely a second nozzle. This part of the apparatus is similar to the atomizers which are so familiarly known and used in procuring fine spray from bottles of perfume, and the action of the steam atomizer invented by Prof. Saroni is precisely similar to that of perfume bottle. The jst of superheated steam, as it emerges from it's nozzle, meets jet of gasoline vapor from the nozzle immediately below the steam nozzle, and steam and gas arc together projected into the fire-box in that in- fnitely divided condition 50 favorable to chemical combination, resulting in intense combustion and the rapid pro- duction of heat. As soon as the pamice- stone has thus been sufficiently heated, the atomizers are shut off and the ordi nary service jets are turned on. By this means steam can be generated from cold water to . pressure of 100 pounds in four minutes. It may be added that the "leg propulsion,'' if it may be so termed, can be used with or without the slow-motion pulley, or the locomo- tive apparatus may be entirely un- coupled, and the power applied to drive a thrsshing-machine, with the wagon remaining stationary.
