as a model cannot by any means always retain the attitude sufficiently long for the design to be wholly carried out at one cast. This arrangement is effected with special reference to painting--that is to say, giving not only form and light and shade, but also the relation and 'values' of tones. The draperies are drawn over, and are made to conform exactly to the forms copied from the nudes of the underpainted picture. This is a cardinal point, because in carrying out the picture the folds are found fitting mathematically on to the nude, or nudes, first established on the canvas. The next step then is to transfer these draperies to the canvas on which the design has been squared off, and this is done with flowing colour in the same monochrome as before over the nudes, to which they are intelligently applied, and which nudes must never--mentally at least--be lost sight of. The canvas has been prepared with a grey tone, lighter or darker, according to the subject in hand, and the effect to be produced. The background and accessories being now added, the whole picture presents a more or less completed aspect--resembling that, say, of a print of any warm tone. In the case of draperies of very vigorous tone, a rich flat local colour is probably rubbed over them, the modelling underneath being, though thin, so sharp and definite as to assert itself through this wash. Certain portions of the picture might probably be prepared with a wash or flat tinting of a colour the _opposite_ of that which it is eventually to receive. A blue sky, for instance, would possibly have a soft, ruddy tone spread over the canvas--the sky, which is a very definite and important part of the President's compositions, being as completely drawn in monochrome as any other portion of the design; or for rich blue mountains a strong orange wash or tint might be used as a bed. The structure of the picture being thus absolutely complete, and the effect distinctly determined by a sketch which it is the painter's aim to equal in the big work, he has nothing to think of but colour, and with that he now proceeds deliberately, but rapidly.
