David Walker, of Newark, N. J., has taken measures to secure a patent for an improvement in the above. The merit of this improvement lies in the use of springs to regulate the motion of the pallets, and to cause them to catch into the teeth of the K scape wheel." The elasticity ot the springs permits them to yield to the pressure of the pallets in case of any departure from the regular movement caused by the catching of the pallets upon the extreme edges of the teeth of the " scape wheel," or by any similar occurrence that tends to raise the pallets more than usual. The advantage gained by this plan is obvious, for the " scape wheel " will be able to continue its motion, and after the obstruction has passed the springs will act upon the pallets as usual. A new steam ferry boat is to supersede the Troy horse boat.
