Black Conté is a hard black chalk made in small sticks of different degrees. It is also put up in cedar pencils. Rather more gritty than red chalk or charcoal, it is a favourite medium with some, and can be used with advantage to supplement charcoal when more precision and definition are wanted. It has very much the same quality of line and so does not show as a different medium. It can be rubbed like charcoal and red chalk and will spread a tone over the paper in very much the same way.

Carbon pencils are similar to Conté, but smoother in working and do not rub.

White chalk is sometimes used on toned paper to draw the lights, the paper serving as a half tone while the shadows and outlines are drawn in black or red. In this kind of drawing the chalk should never be allowed to come in contact with the black or red chalk of the shadows, the half tone of the paper should always be between them.

For rubbed work white pastel is better than the ordinary white chalk sold for drawing, as it is not so hard. A drawing done in this method with white pastel and red chalk is reproduced on page 46 [Transcribers Note: Plate IV], and one with the hard white chalk, on page 260 [Transcribers Note: Plate LIV].

This is the method commonly used for making studies of drapery, the extreme rapidity with which the position of the lights and shadows can be expressed being of great importance when so unstable a subject as an arrangement of drapery is being drawn.

Lithography as a means of artistic reproduction has suffered much in public esteem by being put to all manner of inartistic trade uses. It is really one of the most wonderful means of reproducing an artist's actual work, the result being, in most cases, so identical with the original that, seen together, if the original drawing has been done on paper, it is almost impossible to distinguish any difference. And of course, as in etching, it is the prints that are really the originals. The initial work is only done as a means of producing these.

A drawing is made on a lithographic stone, that is, a piece of limestone that has been prepared with an almost perfectly smooth surface. The chalk used is a special kind of a greasy nature, and is made in several degrees of hardness and softness. No rubbing out is possible, but lines can be scratched out with a knife, or parts made lighter by white lines being drawn by a knife over them. A great range of freedom and variety is possible in these initial drawings on stone. The chalk can be rubbed up with a little water, like a cake of water-colour, and applied with a brush. And every variety of tone can be made with the side of the chalk.

Some care should be taken not to let the warm finger touch the stone, or it may make a greasy mark that will print.

When this initial drawing is done to the artist's satisfaction, the most usual method is to treat the stone with a solution of gum-arabic and a little nitric acid. After this is dry, the gum is washed off as far as may be with water; some of the gum is left in the porous stone, but it is rejected where the greasy lines and tones of the drawing come. Prints may now be obtained by rolling up the stone with an inked roller. The ink is composed of a varnish of boiled linseed oil and any of the lithographic colours to be commercially obtained.

The ink does not take on the damp gummed stone, but only where the lithographic chalk has made a greasy mark, so that a perfect facsimile of the drawing on stone is obtained, when a sheet of paper is placed on the stone and the whole put through the press.

The medium deserves to be much more popular with draughtsmen than it is, as no more perfect means of reproduction could be devised.

The lithographic stone is rather a cumbersome thing to handle, but the initial drawing can be done on paper and afterwards transferred to the stone. In the case of line work the result is practically identical, but where much tone and playing about with the chalk is indulged in, the stone is much better. Lithographic papers of different textures are made for this purpose, but almost any paper will do, provided the drawing is done with the special lithographic chalk.

Pen and ink was a favourite means of making studies with many old masters, notably Rembrandt. Often heightening the effect with a wash, he conveyed marvellous suggestions with the simplest scribbles. But it is a difficult medium for the young student to hope to do much with in his studies, although for training the eye and hand to quick definite statement of impressions, there is much to be said for it. No hugging of half tones is possible, things must be reduced to a statement of clear darks—which would be a useful corrective to the tendency so many students have of seeing chiefly the half tones in their work.

The kind of pen used will depend on the kind of drawing you wish to make. In steel pens there are innumerable varieties, from the fine crow-quills to the thick "J" nibs. The natural crow-quill is a much more sympathetic tool than a steel pen, although not quite so certain in its line. But more play and variety is to be got out of it, and when a free pen drawing is wanted it is preferable.

Reed pens are also made, and are useful when thick lines are wanted. They sometimes have a steel spring underneath to hold the ink somewhat in the same manner as some fountain pens.

There is even a glass pen, consisting of a sharp-pointed cone of glass with grooves running down to the point. The ink is held in these grooves, and runs down and is deposited freely as the pen is used. A line of only one thickness can be drawn with it, but this can be drawn in any direction, an advantage over most other shapes.

Etching is a process of reproduction that consists in drawing with a steel point on a waxed plate of copper or zinc, and then putting it in a bath of diluted nitric acid to bite in the lines. The longer the plate remains in the bath the deeper and darker the lines become, so that variety in thickness is got by stopping out with a varnish the light lines when they are sufficiently strong, and letting the darker ones have a longer exposure to the acid.

Many wonderful and beautiful things have been done with this simple means. The printing consists in inking the plate all over and wiping off until only the lines retain any ink, when the plate is put in a press and an impression taken. Or some slight amount of ink may be left on the plate in certain places where a tint is wanted, and a little may be smudged out of the lines themselves to give them a softer quality. In fact there are no end of tricks a clever etching printer will adopt to give quality to his print.

The varieties of paper on the market at the service of the artist are innumerable, and nothing need be said here except that the texture of your paper will have a considerable influence on your drawing. But try every sort of paper so as to find what suits the particular things you want to express. I make a point of buying every new paper I see, and a new paper is often a stimulant to some new quality in drawing. Avoid the wood-pulp papers, as they turn dark after a time. Linen rag is the only safe substance for good papers, and artists now have in the O.W. papers a large series that they can rely on being made of linen only.

It is sometimes advisable, when you are not drawing a subject that demands a clear hard line, but where more sympathetic qualities are wanted, to have a wad of several sheets of paper under the one you are working on, pinned on the drawing-board. This gives you a more sympathetic surface to work upon and improves the quality of your work. In redrawing a study with which you are not quite satisfied, it is a good plan to use a thin paper, pinning it over the first study so that it can be seen through. One can by this means start as it were from the point where one left off. Good papers of this description are now on the market. I fancy they are called "bank-note" papers.
