Fig. 6. Fig. the intended design or pattern may be divided; for instance, in the desig or pattern shown at fig. l,the full design or pattern, it will be seen, i divided into, or consists of, five compartments, and there are, consequently) five of these blocks, similar to figs. 2 to 6, each block being confined to its distinct compartment of the full design or pattern, as shown at e,f, g, h, i, in fig. 1; and in forming and making up these blocks, the diflVrent coloured and description of pieces are to be arranged in the order required to form the pattern. These blocks are next cut up, arranged, and prepared, after the following manner, viz.;—when it is desired that the mosaic should be prepared with the grain or fibre of the wood vertical, or nearly so, first cut the blocks so arranged, in half, in the direction of the dotted line, </ fig. 2, and then cut each of the halves into separate planks, or pieces of the re- quired thicknesses, in the direction of the dotted lines, b, b, b, as shown in fig. 2; and when it is desired that the mosaic should be prepared with the grain or fibre of the wood horizontal, then cut the blocks so arranged across, in the direction of the dotted lines, c, c, c, as shown in fig. 6. Afterwards plane these separate planks or pieces to the exact size of the square or tes- sera of the work, and then proceed to make up the block of the full desigu or pattern, as shown at fig. 1, in the following manner:—take the plank from each of the separate blocks, 2 to 6, and then glue them together, in the order of the pattern and of the numbers of the blocks, with other sheets of cork cut and prepared, and of the thickness as before described, alternately together; then continue on as before, repeating the making up of the full de- sign to the desired length of the block, as shown at fig. 1, as to which, about thirty inches will be found a convenient length. The block thus obtained is then to be sawn in the direction shown by the dotted line, rf, d, d, into sheets of the thickness desired (say -nr^hs of an inch), and each sheet mill present precisely the same design or pattern, and each square or tessera be surrouncled by the cork so introduced in the work as before mentioned, and be in a state for use according to the purpose for which it is intended, ex- cepting that, in cases where wood to be artificially coloured is used, these sheets, or such parts of them as are intended to be artificially coloured, will first require to undergo that process, which is well known, it being at this stage of the manufacture that it is preferred to colour the wood when it is artificially coloured. This mosaic and tessellated work is applicable to flooring, panelling, and veneering, for building purposes ; also to all purposes of cabinet work, fur- niture, and useful and fancy articles for which veneers are now commonly used, and in the finer sorts, where the square or tessera does not exceed three-fourths of an inch, may be used as a loose covering.
