The foundation of this latter is a sound 1 in. board, 2 ft. 6 in. long by 18 in. wide, or of any other convenient dimensions. Upon this is screwed another piece an inch or more thick (Fig. 40), so as to make a step (C C). Both pieces must be dry, so as not to be liable to warp; upon the higher part are screwed two strips of hard wood (B B) about 1.5 in. or 2 in. wide, forming a right angle where they meet. The whole must be very accurately made, and although deal will answer the purpose, hard wood of some kind will be more satisfactory. Beech or oak will do very well.
Fig. 40 — Mitre block.
Suppose a piece of moulding to require mitring; it has only to be laid as shown against the guide bar (B), and sawn off on the line (CC), or laid on the other side against the second guide bar, and similarly cut off. It will be necessary to use both sides in this way, because, although the piece cut off has also an angle of 45 deg., it would need to be turned over and applied to the other, which could not be done without reversing the moulding. In a plain unmoulded strip this, of course, would not signify.
Gilt moulding may be put at each end or not, according to the fancy and pocket of the workman. The case is now finished, and shows the front and two sides of glass framed in by gilt, outside of which is the narrow black line of the wood. If it be desired to get up the wood of the case in a superior manner, it must first be blacked with the glue and lamp-black, sand-papered down, blacked and sand-papered again, and finally French polished.
The most substantial and effective case is the "stop-chamfered" one, made either in deal ebonized, or fancy woods polished. In this the glass is put in from the back with putty, or papered in, and finally held in place by "beads" of wood, the top is lined with linen and coloured in oil, and after the work is put in (from the back) the back-board (previously lined and coloured) is screwed up, and thus you have a case perfectly impervious to dust or to the changes of the atmosphere. Unless the amateur is a good workman, it will be better for him to get such a case turned out by a professional joiner, to ensure clean-cut work.
These are very handsome and neat cases, especially if the back be "ploughed" out deeply to receive a canvas on a stretcher, on which a characteristic scene is painted. In this event the included work must be good, and the fitting-up as plain as possible.
Cases for fishes are best glazed by "sprung" or semi-convex glass for the fronts, which often does away with the necessity for glass ends, and gives also a more artistic and finished appearance.
Glass shades, especially those of an oval shape, suit many birds well, but for large work are more expensive than cases. Stands in black or gilt are usually supplied with them; but those in mahogany, oak, and other fancy woods must be ordered, unless the amateur possesses a lathe, and the requisite knowledge to use it. In fitting up these with rockwork, etc.., it is best to arrange the work on a "false bottom," or at least to cover up with paper the polished stand, lest it be spoiled.
MOUNTS. — "Mounts," which are simply tops of round or oval shades fitted into corresponding stands or frames of wood, or are open cylinders of glass with a flat piece cemented on one end, were, I believe, first invented by Mr. George Ashmead, of Bishopsgate-street, London. They are very effective, and also occupy but little space, as they hang up on the wall in positions where shades or cases will not go.
