In the “wetting division” is received, counted, and “wet down,” all the paper that is to be plate printed. Here, in different stages of progression, we see blank sheets wetted for first printing, and sheets in preparation for second, third, and even fourth printing. The counters of this division put every twenty sheets in the hands of the wetters, who place them between cloths and submerge them in the liquid of the tubs before them. Every one thousand sheets, thus wetted, are placed between wooden boards, under the pressure of two hundred and fifty pounds. In these cerements they remain for three or four hours, when they are taken out, the top sheets made to change places with the middle ones, that uniform dampness may be secured. The sheets are then laid again between the weights, to remain till the next morning, when they are taken out, piled up under damp cloths to wait the call of the plate-printers. All this systematic saturation is indispensable to the securing of a fine print impression. [Illustration: MAKING MONEY.—THE ROOM IN THE TREASURY BUILDING WHERE THE GREENBACKS ARE PRINTED] A distinct account is kept with each printer, which must be “all right” before he goes home. For example, a plate-printer calls at the wetting division for a thousand sheets. These are given him, and charged at once on the books of the division. As fast as he prints his work, he sends it to the office of his printing division, and is credited with all the work that he has accomplished. At the close of the day, if he has any sheets left unprinted, he returns them to the wetting division, and is credited with them as sheets returned. His work performed and work returned must then be ascertained, and his account strictly balanced, before he can leave the Treasury. The wetting division is superintended by Mr. J. H. Lamb, who, with Mr. Ward Morgan, the head of the face-printing division, Mr. Edgar of the examining division, and Mr. Evans, the United States Sealer, have all been chosen to preside over their distinct divisions on account of their practical experience in plate-printing, gained by personal toil at the press itself.
