The wood - preferably lime, or, perhaps, walnut - should be about half an inch thick, with the sides and base dowelled together as suggested in the drawings. The dowels are short, round pegs, which are glued in when the work is put together. The design should be carefully transferred by means of carbon paper, and lined in with pencil, to prevent it being rubbed off while the centre hole for the clock and the edges are being shaped. Most of the cutting should be done with the knife, which should be used with a firm and decisive movement, working clearly to the lines. Great attention should be paid to the principal lines of the design, so as to retain the flow of the curves. When the front and sides are carved, clean up and fit together, and, when fitting in the clock, it will be advisable to work out a semi-circular hollow in a piece of wood about the same thickness as the clock. This block, glued against the back, will form a good support for the body of the clock, and will greatly strengthen the case. - A. C. H.
