The colors are applied to the printing blocks or rolls by an endless band of muslin passing through a tank filled with the color for that particular block. | As the band covered with the color passes from the tank it travels over or beneath a piece of metal having a toothed edge, technically known as a "doctor," and all superfluous paint is removed, running back into the tank. The printing rolls are so adjusted that each portion of the design is closely joined together, producing a har- monious effect. These printing ma chimes print from two to twelve colors at the same time. The colors are prepared by a special process. so that they do not run or blend. The heavier shades are applied last, as a | general thing, though the arrangement of the colors and the printing blocks depends in great measure upon the de- sign wh' oh is to be produced.
 After passing over the cylinder the printed paper is carried to the dryer on an endless chain. This dryer extends the whole length of the factory, and by an ingenious arrangement the endless chain carrying the paper passes around a pillar and returns to the other end of the room. As the paper passes off from the cylinder. it is caught up at intervals of about eight feet on wooden sticks called "carriers These sticks are moved along by little projections on the endless chain, the paper hanging in | loose loops or folds between the ''car- riers" The paper is carried along for a distance of two or three hundred feet over coils of steam-pipe, and thus is quickly dried. After hanging for a length of time varying from six to twenty-four hours, the paper is taken from the carriers and laid in dry room, where it remains until the drying pro- cess is thoroughly complete. It is then taken to another room, where, by ingenious machinery, it is rolled in lengths ofmarketable size. If tis desired to apply coat of bronze powder to make figure, the figure which is to be thus treated is stamped on the paper as it passes through the printing machine with heavy coat of yarnish. Then, after passing once over the coil of steam-pipe in order that the other colors may be dried, the paper is sent through a long air-tight box in which this bronze dust is sifted over the surface from a perforated tray, and the paper then passes around the end of the traveller and back over the hot-air or steam pipes.
 The finest and most elaborate designs, however, are printed by hand. Each color must be stamped separately, and any one can at once distinguish paper that is printed by hand from that printed by machine. In the former at one of of the margins will be found. at dis tances of about eighteen inches, fine lines or dots containing the colors form ing the design. These are the marks guiding the men in their work of stamp ing the pattern. The block or die for each separate portion of the pattern which is.to be printed in a certain color is about eighteen inches in length. The workman presses the due upon pad covered with the color, and then places it upon the paper as it les on the table in front of him, talk ing care that the guide at the edge of the die joins the mark left on the margin of the paper. Placing swivel over the block, he presses lever with his foot, thus stamping the form of the die on the paper. A boy attendant spreads the paper on rack, where it is permitted to dry, and it is then taken to another machine, where the same pro- cess is gone through in printing another portion of the design in another color, and this process is repeated in some in stances a dozen or more times, until the entire design in all its more or less har- monious blending of colors is produced. With hand work the process of applying velvet coat to any figure is much diff ferent from that used in producing a ''bronze'' effect in papers painted by machine. The figure which is to be thus produced in velvet is stamped with a heavy glue; the paper is then passed through long trough having the bot tom and sides of stout canvas. In this trough the floss or material which is used to produce the velvet effect is placed. A boy scatters this material over the surface of the paper, and then, taking couple of sticks in his hand, he beats a tattoo on the pliable bottom of the trough, thoroughly distributing the nOoo ONCI UllC IIS uIc III 1dCI.

 Many of the finer qualities of paper are now made with fine lines pressed in the paper. This is done by passing be- tween two rollers, one of which is brass, on which is engraved the design to be stamped on the paper, the other roller being of wood covered with paper, which by constant pressure has become almost as hard as metal. Between these rolls the paper is subjected to 8 tremen- deus pressure, and it is impossible to efface the lines thus created. These brass rollers. as well as all of the wood en dies used in stamping the designs by hand, and also the cylinder dies used in the machines, are engraved on the manufacturer premises. Many of these dies, especially for work where it is required to produce fine lines, are made by setting pieces of brass into blocks of wood. These pieces of brass are moulded or bent into all sorts of curves and figures, and vary in thick ness from an eighth of an inch to 8 line which is scarcely visible to the eye. On many of these hand-dies, which are not more than two inches long by eighteen inches wide, as many as one hundred to two hundred pieces of brass are thus in- laid.
 Within the last few years the demand for something more substantial and ''dressy" than the ordinary wallpaper has sprung up. To meet the demand, heavy embossed paper has sprung up. This new wall-covering is made of wood fiber, pressed on a background of linen which has been subjected to a special
