A NATURE CAMERA

base-board at K (Fig. 12). Now fix two screws, with small washers on them, 

 through the slot in the base-board, into the bottom of the camera body, and 

 you will find that, by turning the 

 finger screw or cramp, your camera 

 body will move in or out along the 

 base-board for some two inches. This 

 will enable you to focus any object 

 you desire when the camera is complete. 

 The next business is to make a 

 short bellows, to be attached to the 

 camera body and the front. 



The simplest way of making this is 

 as follows : Make a box to act as a 

 " mould," about 3^ inches wide by 3 

 inches deep the length being immaterial, say 6 inches. The material for the 

 bellows (the covering of an old umbrella will do excellently), 7 inches long by 

 14 inches wide, is wrapped round the box ; there will be an 

 inch to spare, which is glued down upon the cloth it over- 

 laps. The whole then forms a sort of sleeve over the box. 

 Now you require twelve slips of cardboard stout postcard 

 cut into the shape of one of the sections in Fig. 15, each 

 an inch wide and 3! inches long. In addition twelve 

 other similar pieces, 3 inches long, are needed. These are 

 to be glued down upon the material, six on each side, with 

 an interval of inch between each piece. Fig. 15 shows 

 the pattern of one side. Then another piece of material the same size as the 

 first is glued down over the whole, and the box is put aside for the glue to 

 get nearly dry. When that is the case, you draw off this " sleeve " 

 and fold in the corners between the cardboard slips ; this is a 

 simple process and is quickly accomplished, and has the effect of 

 turning the " sleeve " into a neat, strong bellows, to be attached 

 to the camera body and front. 



The last business is the making of the lens board. On the 

 outer side of the camera front fix four small slips of wood to 

 enclose a square, in the centre of which is the lens hole, about 2| inches 

 each way (Fig. 16). Make a panel (Fig. 17) to fit inside this square, to be

held in place by two small turn-pins (which can be seen 

 at A and B, in Fig. 16). In the centre of this small 

 panel is another hole, of the same size or a trifle smaller 

 than that in the camera front. 



Now you require a wooden pill-box, with a hole (of the 

 same size) in the bottom, which is to be glued or screwed 

 down upon the panel. The lid of the pill-box will act 



as the cap by means of which you make your exposures.
