The remainder of the color is to be taken off the size by the aid of strips of paper and this is done in the following way: one strip is inserted into the size at the left end of the trough in such a way that it slightly enters the size, then by the aid of a second strip of paper, the top of the color is taken off beginning at the right end of the trough and moving the film to the left till it is brought between the two strips of paper and can be removed from the trough into a basin which is kept ready, to receive the waste color. If the colors are quickly removed in this way, the size itself remains perfectly clean even though a large number of books be treated. On good work, the book at first is only cut in front. As soon as the front edge is marbled and dry the book is backed, and cut at the top and bottom; both edges are wetted with alum water and again the colors are thrown upon the size taking care, that the scales of the upper edge run in the same direction towards the fore-edge as those of the lower one. In more common bindings, all three sides are cut together and after the front edge is marbled and the book is rounded and backed, the marbling of the upper and lower edges is executed without delay. The rounding of the book must be done before the marbling of the upper and lower edges, because the comb would become disarranged, if the rounding were executed afterwards. Remember that always before throwing on the colors, the top of the size must be taken off by the aid of the piece of board, as, by evaporation, a film is formed over the surface which does not permit the expanding of the colors. The quicker the marbling is executed, so much more beautiful will be the edges. PEACOCK MARBLE. PEACOCK MARBLE. (SEE SPECIMEN PLATES.) Peacock marble is one of the newest and prettiest of marbles. It has been much used in recent times for end papers of books, which receive the same edges and in this connection gives a beautiful effect. The method of preparation is generally the same as that of the comb-edge, the difference being this, that, after the colors have been drawn by the stylus into wavy lines, it is drawn by the aid of a movable comb, (the preparation of which I shall describe among the tools) in such a way, that for a distance of 1/2 inch the comb is made wider and again after a distance of 1/2 inch is made narrower. This is continued until the entire marble is crossed by this opening and closing comb; of which a trial is all that is necessary to make it all clear. THE BOUQUET MARBLE. THE BOUQUET MARBLE. (SEE SPECIMEN PLATES.) There is no doubt that from among the drawn marbles the bouquet marble is one of the most brilliant, as it can be compared to a number of buttonieres placed alongside each other, if the combination of colors is a good one.
