te details require great care, and it is more awkward to get small washes level than larger ones. The first thing to be done is to buy our materials, and these we can get all neatly arranged in a box. The colours are: two flesh tints, light and golden yellow, vermilion and carmine, blue, violet, purple, light and wood brown, green, and black. All the colours are dry, except black; and ordinary Chinese white is used, as there is no white specially made for canvasine. There are two bottles of medium, one adhesive and one preservative. Camel's-hair brushes of various sizes, canvas and stretchers, a roller, and a squeegee, or presser, are also requisite. Having all our materials at hand, let us set to work. The stretcher has been bought to suit the size of the photograph, but probably the latter will have to be cut a little round the edges, to make it just about an eighth of an inch smaller than the former. Take some of the prepared canvas, and cut it an inch and a half larger than the photo; wet it thoroughly, and fasten it to a board with drawing-pins, the prepared side uppermost. The back of the photo will require to be rubbed with glass-paper, if it is a thick one; not otherwise, for fear of making holes in it. To manage this carefully is important. A sheet of clean paper should be laid on a drawing-board, and the photo placed on it face downwards, and firmly secured with drawing-pins. Now rub it gently with the glass-paper, until the picture is rendered semi-transparent. Then take it from the board, and give it a bath in the solution. Lay it in a dish, and cover it entirely with the solution, letting it remain there for a few minutes; lift it out, and again lay it on the board face downwards, and with a small sponge dab off any superfluity of liquid. Pour that which is left in the dish back into the bottle. The bottle of canvasine adhesive is next needed. With a brush well filled with it, lay a thick coating all over the back of the photo as evenly as possible, then take up the picture, and place it in exact position on the canvas which is stretched on the board, and now the face must be uppermost. Notice particularly that the photo lies straight with the threads of canvas; if it is crookedly placed it cannot be expected to look well; the perpendicular and horizontal threads should run perfectly level with the top and bottom and sides of the picture. Press down the photo with the hand, and then slightly roll
