TO MAKE A STEREOSCOPE SHADE.

The making of the shade for a stereoscope is, somewhat difficult, and unless great care is taken in turning it to shape there may bo several failures. The following particulars and illustrations will doubtless be helpful. First procure a piece of dry wood 3J in. by 3 in. and about 5§ in. long. Now cut a pieoe of paper to the shape of Fig. 1, and piace it on the above piece of wood lengthwise, and line with a pencil to the pattern. Then cut to line, and you will have a block as Fig. 1, on which the veneer for the shade is secured and turned to shape. In constructing a stereoscope shade, make it from two pieces of veneer with the .grain crosabtg each other. These pieces which should be 10 in. or 11 in. long and aboat 34 in. wide, are placed in a receptacle of hot water and allowed to remain for some twenty minutes or haM an hour. The pieces of veneer with the grain rimming vertical are then taken owt of the waiter and fastened on the block (Fig. 1) with a piece ©f fine twine or thread. A pot of good hot glue should be near at hand, and the veneer given a thin coat. The other piece of veneer, with the grain running lengthwise, is taken o«t of the water, placed quickly ©n the glued piece, and fastened with several turns of strong twine. Aitow to remain for a day or so for the glue to set, so that when the joined veneer is released it will maintain the contour pf the block (Fig. 1.)

A paper pattern of the shade (Fig. 2) is then placed on the vaaeer, and a line made to this pattern while the veneer is still on the fclock. Then cut 1 , to the line with a sharp knife or a chisel, rub up tbe surface with fine glasspeper, and, before removing the shade from the bloefe, pierce five small holes as indicated at A in Pig. 2. These holes are to receive brass-headed nails for securing the shade to the lens frame. Next remove the shade from the block, and nicely clean up the cut edge with fine glasspaper. Before securing the shade to the lens frame, the rebate in which it is secured should have a thin coat of glue, after which the shade should be quickly nailed down, beginning with the centre nail and nailing from right to left and left to right. It may be mentioned that a lens frame may be more easily made from the solid piece of wood. Holes about 1 in. or 1} in. diameter are bored with a centre-bit, then recessed square at the bask with a ehisel, and the lens placed in tbe recesses and stopped with four glued slips of wood. If preferred the stereoscope may be made completely of oak.— Stereoscope (Scorrier).
