Do not rub out, if you can possibly help it, in drawings that aim at artistic expression. In academic work, where artistic feeling is less important than the discipline of your faculties, you may, of course, do so, but even here as little as possible. In beautiful drawing of any facility it has a weakening effect, somewhat similar to that produced by a person stopping in the middle of a witty or brilliant remark to correct a word. If a wrong line is made, it is left in by the side of the right one in the drawing of many of the masters. But the great aim of the draughtsman should be to train himself to draw cleanly and fearlessly, hand and eye going together. But this state of things cannot be expected for some time.
Let painstaking accuracy be your aim for a long time. When your eye and hand have acquired the power of seeing and expressing on paper with some degree of accuracy what you see, you will find facility and quickness of execution will come of their own accord. In drawing of any expressive power this quickness and facility of execution are absolutely essential. The waves of emotion, under the influence of which the eye really sees in any artistic sense, do not last long enough to allow of a slow, painstaking manner of execution. There must be no hitch in the machinery of expression when the consciousness is alive to the realisation of something fine. Fluency of hand and accuracy of eye are the things your academic studies should have taught you, and these powers will be needed if you are to catch the expression of any of the finer things in form that constitute good drawing.
Try and express yourself in as simple, not as complicated a manner as possible. Let every touch mean something, and if you don't see what to do next, don't fill in the time by meaningless shading and scribbling until you do. Wait awhile, rest your eye by looking away, and then see if you cannot find something right that needs doing.
Before beginning a drawing, it is not a bad idea to study carefully the work of some master draughtsman whom the subject to be drawn may suggest. If you do this carefully and thoughtfully, and take in a full enjoyment, your eye will unconsciously be led to see in nature some of the qualities of the master's work. And you will see the subject to be drawn as a much finer thing than would have been the case had you come to it with your eye unprepared in any way. Reproductions are now so good and cheap that the best drawings in the world can be had for a few pence, and every student should begin collecting reproductions of the things that interest him.
This is not the place to discuss questions of health, but perhaps it will not be thought grandmotherly to mention the extreme importance of nervous vitality in a fine draughtsman, and how his life should be ordered on such healthy lines that he has at his command the maximum instead of the minimum of this faculty. After a certain point, it is a question of vitality how far an artist is likely to go in art. Given two men of equal ability, the one leading a careless life and the other a healthy one, as far as a healthy one is possible to such a supersensitive creature as an artist, there can be no doubt as to the result. It is because there is still a lingering idea in the minds of many that an artist must lead a dissipated life or he is not really an artist, that one feels it necessary to mention the subject. This idea has evidently arisen from the inability of the average person to associate an unconventional mode of life with anything but riotous dissipation. A conventional life is not the only wholesome form of existence, and is certainly a most unwholesome and deadening form to the artist; and neither is a dissipated life the only unconventional one open to him. It is as well that the young student should know this, and be led early to take great care of that most valuable of studio properties, vigorous health.

MATERIALS
The materials in which the artist works are of the greatest importance in determining what qualities in the infinite complexity of nature he selects for expression. And the good draughtsman will find out the particular ones that belong to whatever medium he selects for his drawing, and be careful never to attempt more than it is capable of doing. Every material he works with possesses certain vital qualities peculiar to itself, and it is his business to find out what these are and use them to the advantage of his drawing. When one is working with, say, pen and ink, the necessity for selecting only certain things is obvious enough. But when a medium with the vast capacity of oil paint is being used, the principle of its governing the nature of the work is more often lost sight of. So near can oil paint approach an actual illusion of natural appearances, that much misdirected effort has been wasted on this object, all enjoyment of the medium being subordinated to a meretricious attempt to deceive the eye. And I believe a popular idea of the art of painting is that it exists chiefly to produce this deception. No vital expression of nature can be achieved without the aid of the particular vitality possessed by the medium with which one is working. If this is lost sight of and the eye is tricked into thinking that it is looking at real nature, it is not a fine picture. Art is not a substitute for nature, but an expression of feeling produced in the consciousness of the artist, and intimately associated with the material through which it is expressed in his work—inspired, it may be, in the first instance, by something seen, and expressed by him in painted symbols as true to nature as he can make them while keeping in tune to the emotional idea that prompted the work; but never regarded by the fine artist as anything but painted symbols nevertheless. Never for one moment does he intend you to forget that it is a painted picture you are looking at, however naturalistic the treatment his theme may demand.
