The machine should be raised suffi- ciently above the floor to permit a broad-wheeled hand truck, carry- ing a box 12 or 15 inches deep and having one side hinged so as to drop down, to be placed directly beneath the chute down which the slices pass. When the box becomes tilled the truck is replaced by another, and the loaded truck is rolled into the kiln, the side dropped, and the contents spread upon the kiln floor. The lowered side of the box forms an incline down which the fruit runs without injury, which is an advantage, as the freshly sliced rings are easily broken, and unnecessary or rough handling at this time lowers the grade of the fruit by increasing the percentage of broken pieces. The loading of the kiln floor is begun at the corner farthest from the door, each truck load being spread as uniformly as possible to a depth of 5 or 6 inches by means of a broad-bladed wooden shovel and a wooden Fig. 10.—An apple bleacher. In this arrangement of equipment the fruit passes rapidly through the various stages of preparation, a given apple reaching the bleacher within H to 2 minutes after it is placed upon the paring machine, thus eliminating the discoloration resulting from standing in the air. All transfers of the bulky material from floor to floor or about the build- ing are accomplished by automatic power conveyors or by gravity, the hand labor involved being reduced to the actual operations of feeding peeling machines, trimming, and spreading the sliced fruit on the kiln floor. This work does not require great physical strength and is almost universally performed by women and girls. THE PRUNE TUNNEL EVAPORATOR. The term " tunnel evaporator," or " prune tunnel,&q
