VVe have had occasion to observe, for some inontlis past, its application to this use, on one of the passenger cars on the New- ton special train ofthe Boston and Worccstct" rail- road. It is thereused not only for the springs on which the car rests, but for the .spi'ings zittziched to the draw bar, at each end of the car, to prevent any jar on the sudden comtnenceinent, or interruption or the motion of the car. For both these pi.irpos.es it appears to be admirably adapted, and we do not learn that during the period in which it has been used, any defect in it has been discovered. I t ren- ders the movements of the car extremely easy, and protects it more etleciually, we think, than any other spring which we have seen in use, front every harsh or unpleasant motion, either vertical or horizontal. lt is also simple in its form and application, ex- tremely light, and little liable to get out of repair. During the period of’ some months in which we have seen thesprings in "operation, there is no apparent wear or diminution of its efficiency.
