In the earlier history of art it was not so necessary to insist on the limitations imposed by different mediums. With their more limited knowledge of the phenomena of vision, the early masters had not the same opportunities of going astray in this respect. But now that the whole field of vision has been discovered, and that the subtlest effects of light and atmosphere are capable of being represented, it has become necessary to decide how far complete accuracy of representation will help the particular impression you may intend your picture or drawing to create. The danger is that in producing a complete illusion of representation, the particular vitality of your medium, with all the expressive power it is capable of yielding, may be lost.
Perhaps the chief difference between the great masters of the past and many modern painters is the neglect of this principle. They represented nature in terms of whatever medium they worked in, and 273never overstepped this limitation. Modern artists, particularly in the nineteenth century, often attempted to copy nature, the medium being subordinated to the attempt to make it look like the real thing. In the same way, the drawings of the great masters were drawings. They did not attempt anything with a point that a point was not capable of expressing. The drawings of many modern artists are full of attempts to express tone and colour effects, things entirely outside the true province of drawing. The small but infinitely important part of nature that pure drawing is capable of conveying has been neglected, and line work, until recently, went out of fashion in our schools.
There is something that makes for power in the limitations your materials impose. Many artists whose work in some of the more limited mediums is fine, are utterly feeble when they attempt one with so few restrictions as oil paint. If students could only be induced to impose more restraint upon themselves when they attempt so difficult a medium as paint, it would be greatly to the advantage of their work. Beginning first with monochrome in three tones, as explained in a former chapter, they might then take for figure work ivory black and Venetian red. It is surprising what an amount of colour effect can be got with this simple means, and how much can be learned about the relative positions of the warm and cold colours. Do not attempt the full range of tone at first, but keep the darks rather lighter and the lights darker than nature. Attempt the full scale of tone only when you have acquired sufficient experience with the simpler range, and gradually add more colours as you learn to master a few. But restraints are 274not so fashionable just now as unbridled licence. Art students start in with a palette full of the most amazing colours, producing results that it were better not to discuss. It is a wise man who can discover his limitations and select a medium the capacities of which just tally with his own. To discover this, it is advisable to try many, and below is a short description of the chief ones used by the draughtsman. But very little can be said about them, and very little idea of their capacities given in a written description; they must be handled by the student, and are no doubt capable of many more qualities than have yet been got out of them.
Lead Pencil
This well-known medium is one of the most beautiful for pure line work, and its use is an excellent training to the eye and hand in precision of observation. Perhaps this is why it has not been so popular in our art schools lately, when the charms of severe discipline are not so much in favour as they should be. It is the first medium we are given to draw with, and as the handiest and most convenient is unrivalled for sketch-book use.
It is made in a large variety of degrees, from the hardest and greyest to the softest and blackest, and is too well known to need much description. It does not need fixing.
For pure line drawing nothing equals it, except silver point, and great draughtsmen, like Ingres, have always loved it. It does not lend itself so readily to any form of mass drawing. Although it is sometimes used for this purpose, the offensive shine that occurs if dark masses are introduced is against its use in any but very lightly shaded work.

FROM A SILVER-POINT DRAWING
275Its charm is the extreme delicacy of its grey-black lines.
Silver and Gold Point.
Similar to lead pencil, and of even greater delicacy, is silver-point drawing. A more ancient method, it consists in drawing with a silver point on paper the surface of which has been treated with a faint wash of Chinese white. Without this wash the point will not make a mark.
For extreme delicacy and purity of line no medium can surpass this method. And for the expression of a beautiful line, such as a profile, nothing could be more suitable than a silver point. As a training to the eye and hand also, it is of great value, as no rubbing out of any sort is possible, and eye and hand must work together with great exactness. The discipline of silver-point drawing is to be recommended as a corrective to the picturesque vagaries of charcoal work.
A gold point, giving a warmer line, can also be used in the same way as a silver point, the paper first having been treated with Chinese white.
Charcoal.
Two extreme points of view from which the rendering of form can be approached have been explained, and it has been suggested that students should study them both separately in the first instance, as they each have different things to teach. Of the mediums that are best suited to a drawing combining both points of view, the first and most popular is charcoal.
Charcoal is made in many different degrees of hardness and softness, the harder varieties being capable of quite a fine point. A chisel-shaped point is the most convenient, as it does not wear away so quickly. And if the broad side of the chisel point 276is used when a dark mass is wanted, the edge can constantly be kept sharp. With this edge a very fine line can be drawn.
Charcoal works with great freedom, and answers readily when forceful expression is wanted. It is much more like painting than any other form of drawing, a wide piece of charcoal making a wide mark similar to a brush. The delicacy and lightness with which it has to be handled is also much more like the handling of a brush than any other point drawing. When rubbed with the finger, it sheds a soft grey tone over the whole work. With a piece of bread pressed by thumb and finger into a pellet, high lights can be taken out with the precision of white chalk; or rubber can be used. Bread is, perhaps, the best, as it does not smudge the charcoal but lifts it readily off. When rubbed with the finger, the darks, of course, are lightened in tone. It is therefore useful to draw in the general proportions roughly and rub down in this way. You then have a middle tone over the work, with the rough drawing showing through. Now proceed carefully to draw your lights with bread or rubber, and your shadows with charcoal, in much the same manner as you did in the monochrome exercises already described.
All preliminary setting out of your work on canvas is usually done with charcoal, which must of course be fixed with a spray diffuser. For large work, such as a full-length portrait, sticks of charcoal nearly an inch in diameter are made, and a long swinging line can be done without their breaking.
For drawings that are intended as things of beauty in themselves, and are not merely done as a preparatory study for a painting, charcoal is per277haps not so refined a medium as a great many others. It is too much like painting to have the particular beauties of a drawing, and too much like drawing to have the qualities of a painting. However, some beautiful things have been done with it.
It is useful in doing studies where much finish is desired, to fix the work slightly when drawn in and carried some way on. You can work over this again without continually rubbing out with your hand what you have already drawn. If necessary you can rub out with a hard piece of rubber any parts that have already been fixed, or even scrape with a pen-knife. But this is not advisable for anything but an academic study, or working drawings, as it spoils the beauty and freshness of charcoal work. Studies done in this medium can also be finished with Conté chalk.
There is also an artificial charcoal put up in sticks, that is very good for refined work. It has some advantages over natural charcoal, in that there are no knots and it works much more evenly. The best natural charcoal I have used is the French make known as "Fusain Rouget." It is made in three degrees, No. 3 being the softest, and, of course, the blackest. But some of the ordinary Venetian and vine charcoals sold are good. But don't get the cheaper varieties: a bad piece of charcoal is worse than useless.
Charcoal is fixed by means of a solution of white shellac dissolved in spirits of wine, blown on with a spray diffuser. This is sold by the artists' colourmen, or can be easily made by the student. It lightly deposits a thin film of shellac over the work, acting as a varnish and preventing its rubbing off.
278Charcoal is not on the whole the medium an artist with a pure love of form selects, but rather that of the painter, who uses it when his brushes and paints are not handy.
Red Chalk (Sanguine).
A delightful medium that can be used for either pure line work or a mixed method of drawing, is red chalk. This natural red earth is one of the most ancient materials for drawing. It is a lovely Venetian red in colour, a............
