The method of making up a "mount" is as follows: Procure from a glass merchant the top of a shade, let us say 12 in. in diameter by 7 in. high. To this have a stand or rim turned out of thoroughly dry wood of sufficient size to overlap the shade 1 in. all round — 14 in. in diameter, therefore, for a 12 in. shade. A groove should be turned in them stand of sufficient width to allow the glass to play freely.

The groove, however, should be so arranged that the excess in width should fall outside the glass. The centre of the stand inside the groove being tinted for a sky, as desired, the objects, whether small birds or butterflies, are introduced in the usual manner, and the glass is then cemented, in the groove, over them.

Waste cylinders of glass may be economised for making mounts. It will then, however, be necessary to have a circular plate for the top cut by a glazier's turn-table. These are really better for showing up anything than the round-topped mounts, as they cast no reflection; but the top plates are harder to put on and to keep on when finished. Strongly pasted black tape will do to fix the very small ones, but for larger the tops should be cemented with thick white-lead, left to dry, and then further cemented with narrow tape smeared with white-lead, or any of the cements given in chapter IV. If it be desired to give a rounded edge to this taping, plaster or whiting mixed with glue and lamp-black may be laid on thickly, rubbed down with fine sand-paper, and polished, or if the black is left out, the cement may be gilded, after the manner of picture frames.

The stand itself may be "dished" out in the centre, in concave form, and thus more room allowed for the enclosed specimens; but in this case the stand must be of some thickness.

At one time the glasses were put in the stands with glue and cork, or glue and paper, until it was found, in nine cases out of ten, that glue, under atmospheric changes, sooner or later broke the glass, or else entirely released it. Putty was then used, but that failed to hold with the tenacity required, as there was a constant tendency of the shade to fall out by its natural weight when hanging up. I have accordingly mixed white-lead with putty with better results, in the proportion of two parts putty; one ditto white-lead (thick, such as gasfitters use); one-eighth ditto gold size — or I have used red-lead, mixed with common putty and boiled oil; and, again, simply plaster of Paris mixed with water. These last two are the best holdfasts of glass within my experience.

Supposing the stand to be ebonized, or of mahogany or any other fancy wood, the putty or plaster can be coloured to any required tint, or if the stand is gilt the cement can be gilded over. Failing to make a very neat job, it will be necessary to wind a piece of chenille around the shade in order to hide the junction.

As it is very difficult to prevent a small percentage of the cement from working inside, and thus spoiling the neatness of the sky effect, I have devised the following plan, which I do not think is generally known: Instead of using a solid stand with groove for the back of the mount, I turn a rim of wood to form a ring, in such a manner that it shall just pass over the shade without allowing the latter to fall through at its bottom edge. Underneath this rim, or ring, I turn it out to within a quarter of an inch of its edge to receive the back, turned out of a piece of thinner wood.

The rim of wood is best turned by being nearly cut through on its upper or pattern side, the wood then reversed on the lathe, turned out to receive the back, then altered again, and the rim cut entirely through. To fix this, the rim is fitted on over the glass, and kept in place with cement. The work is made up on the back, which is then screwed, or pasted, or glued, in the hollow turned out at the back of the rim. By this method there is no cement showing inside on the sky-line of the work when finished, nor can the glass possibly tumble out, being, of course, held by the rim, which is of necessity smaller than the bottom of the glass. Such rims may, of course, be ebonized, of fancy woods, or gilded, according to the taste of the workman. A small screw-plate with ring should be attached to hang it up by.

A modification of the "mount" is made by securing five pieces of glass together in the usual manner, by tape pasted on each edge to make a square glass cover, making up the work on a piece of board of the required size, rebated or grooved all around, or by nailing on strips of wood to receive the glass cover, which is then pasted or cemented to the edges of the board, and finally finished off by dropping over all picture-frame moulding, cut and joined to size, to which the back is screwed. This style does either for fishes or dead game to stand upon a hall table, or easily becomes a "mount" by the simple process of screwing on "plate-rings," and hanging it up on a wall.

The colouring of the backs of cases and mounts is of two kinds — distemper and oil; that is to say, supposing paper, calico or sheeting is used for the back of the cases or mounts. Colour the paper or other material — if you wish to show a toned sky — with whiting in which a little glue-water or paste is dissolved, or with common flake-white and size (note that there must be a good body of white to give a luminous appearance), tinting at the same time with blue, shading off into pink, etc.. The colours most useful are ultramarine, vermilion, and chrome yellow in powder. This colouring will not do if putty is used to put the glass in with, as the oil flies over the tinted sky. For oil painting place a thin calico or canvas on the backs, and colour with the tints you desire, mixed in oil and turps. Putty can be used in any part with this colouring. One coat of colour is sufficient, as if another is added an unpleasant glaze is the result.
