these artists. The Venetians are not supposed to have cultivated the art of engraving rough ground with polished relief on Glass, which is now, and has been, for perhaps two centuries, so successfully pursued by the Bohemians. Their excellent arabesque borders, animals, and landscapes, are executed in quantities, with surprising rapidity, and at a low rate of wages; from ten to fifteen shillings a-week being in Bohemia a fair remuneration even for a tolerably artistic engraver, who would earn fifty shillings a-week if working in London.

Copper wheels, and finely pulverized emery mixed with oil, are used to execute the outline and ground of the modern engraver's work; and for the polished work, lead wheels, and very finely pulverized emery, are employed.* The most elaborate and splendidly executed artistic specimen of engraving, is now at the Falcon Glass Works, and is the work of a German artist, who devoted several years to its accurate details. The subject is from the picture of Lebrun, representing the final battle and triumph of Alexander the Great over Darius, which ended in the entire overthrow of the Persian empire.

Coarse patterns for hall lamps are engraved by the Glass-cutter's smoothing wheel. The contrast of the polish of a wood wheel upon a ground roughened by sand is often effective, though the range of pattern is somewhat curtailed by the large size of the cutter's wheels, rendering it difficult to execute curvilinear designs. The Venetians practised a curious art of engraving with the point of a diamond, or broken steel file.
