Arrangement of Trolleys.—A very good method of handling the pulp is shown in Fig. 15. It is supposed, in this case, that the pulp is brought to the press by the trolley shown at G. The wet pulp is delivered from this trolley to trolley D, which is simply a large table mounted on a pair of wheels, so that it can be brought near to the press trolley that is being loaded, and within easy reach of the pressman. One press trolley with its load of pulp is always under pressure, the other one in the meantime being either discharging or loading with wet pulp again. The operation is somewhat as follows : The pressman, in loading trolley B, places on it first a layer of felts, then a layer of pulp, and so on alternately until the pile will just go under the top of the press. B is now run into the press and the pressure turned on. While this load is being pressed he proceeds to load trolley C, from the supply on the wet pulp table D. When B has been pressed sufficiently, the water is turned off, which lowers the trolley down on the rails again. It is now run out, and trolley C run in and the water turned on as before. B is now unloaded, the pressed pulp being thrown on the dry pulp table at E and the felts on the felt rack. When B is empty it is immediately loaded again, the trolley D being run up conveniently near for the purpose. In this way there is no carrying of the pulp by the workman, an advantage which will easily be seen when the quantity handled is considered. The rails for the press trolleys are laid across the pla
