It is the last of these three men who stands in the attitude of full and true appreciation. The first of the three uses the picture simply as a point of departure; his thought travels away from the canvas, and he builds up the entire experience out of his own knowledge and store of associations. The second man comes a little nearer to appreciation, but even he falls short of full realization, for he stops at the actual material work itself. His interest in the technical execution and his pleasure in the sensuous qualities of the medium do not carry him through the canvas and into the emotion which it was the artist's purpose to convey. Only he truly appreciates the painting of the "Sower" who feels something of what Millet felt, partaking of the artist's experience as expressed by means of the picture, and making it vitally his own.

But before the appreciator can have brought himself to the point of perception where he is able to respond directly to the significance of art and to make the artist's emotion a part of his own emotional experience, he must needs have traveled a long and rather devious way. Appreciation is not limited to the exercise of the intellect, as in the recognition of the subject of a work of art and in the interest which the technically minded spectator takes in the artist's skill. It does not end with the gratification of the senses, as with the delight in harmonious color and rhythmic line and ordered mass. Yet the intellect and the senses, though they are finally but the channel through which the artist's meaning flows to reach and rouse the feelings, nevertheless play their part in appreciation. Between the spirit of the artist and the spirit of the appreciator stands the individual work of art as the means of expression and communication. In the work itself emotion is embodied in material form. The material which art employs for expression constitutes its language. Certain principles govern the composition of the work, certain processes are involved in the making of it, and the result possesses certain qualities and powers. The processes which enter into the actual fashioning of the work are both intellectual and physical, requiring the exercise of the artist's mind in the planning of the work and in the directing of his hand; so far as the appreciator concerns himself with them, they address themselves to his intellect. The finished work in its material aspect possesses qualities which are perceived by the senses and which have a power of sensuous delight. Upon these processes and these qualities depends in part the total character of a work of art, and they must be reckoned with in appreciation.

In his approach to any work of art, therefore, the layman is confronted first of all with the problem of the language which the work employs. Architecture uses as its language the structural capabilities of its material, as wood or stone, bringing all together into coherent and serviceable form. Poetry is phrased in words. Painting employs as its medium color and line and mass. At the outset, in the case of any art, we have some knowledge of the signification of its terms. Here is a painting of a sower. Out of previous experience of the world we easily recognize the subject of the picture. But whence comes the majesty of this rude peasant, the dignity august of this rough and toil-burdened laborer, his power to move us? In addition to the common signification of its terms, then, language seems to have a further expressiveness, a new meaning imparted to it by the way in which the artist uses it. In a poem we know the meaning of the words, but the poetry of it, which we feel rather than know, is the creation of the poet, wrought out of the familiar words by his cunning manipulation of them.

"The grey sea and the long black land;
And the yellow half-moon large and low;
And the startled little waves that leap
In fiery ringlets from their sleep,
As I gain the cove with pushing prow,
And quench its speed i' the slushy sand.

"Then a mile of warm sea-scented beach;
Three fields to cross till a farm appears;
A tap at the pane, the quick sharp scratch
And blue spurt of a lighted match,
And a voice less loud, thro' its joys and fears,
Than the two hearts beating each to each!"

A drama in twelve lines. These are words of common daily usage, every one,—for the most part aggressively so. But the romance which they effuse, the glamour which envelops the commonplace incident as with an aura, is due to the poet's strategic selection of his terms, the one right word out of many words that offered, and his subtle combination of his terms into melody and rhythm. The wonder of the poet's craft is like the musician's,—

"That out of three sounds he frame, not a fourth sound, but a star."

A building rises before us; we recognize it as a building, and again easily we infer the purpose which it serves, that it is a temple or a dwelling. And then the beauty of it, a power to affect us beyond the mere feet that it is a building, lays hold upon us, an influence emanating from it which we do not altogether explain to ourselves. Simply in its presence we feel that we are pleased. The fact, the material which the artist uses, exists out there in nature. But the beauty of the building, the majesty and power of the picture, the charm of the poem,—this is the art of the artist; and he wins his effects by the way in which he handles his materials, by his technique. Some knowledge of technique, therefore,—not the artist's knowledge of it, but the ability to read the language of art as the artist intends it to be read,—is necessary to appreciation.

The hut which the traveler through a wild country put together to provide himself shelter against storm and the night was in essence a work of art. The purpose of his effort was not the hut itself but shelter, to accomplish which he used the hut as his means. The emotion of which the work was the expression, in this case the traveler's consciousness of his need, embodied itself in a concrete form and made use of material. The hut which he conceived in response to his need became for him the subject or motive of his work. For the actual expression of his design he took advantage of the qualities of his material, its capabilities to combine thus and so; these inherent qualities were his medium. The material wood and stone which he employed were the vehicle of his design. The way in which he handled his vehicle toward the construction of the hut, availing himself of the qualities and capabilities of his material, might be called his technique.

The sight of some landscape wakens in the beholder a vivid and definite emotion; he is moved by it to some form of expression. If he is a painter he will express his emotion by means of a picture, which involves in the making of it certain elements and certain processes. The picture will present selected facts in the landscape; the landscape, then, as constructed according to the design the painter has conceived of it, becomes the motive or subject of his picture. The particular aspects of the landscape which the picture records are its color and its form. These qualities of color and form are the painter's medium. An etching of the scene would use not color but line to express the artist's emotion in its presence; so line is the medium of etching. But "qualities" of objects are an abstraction unless they are embodied in material. In order, therefore, to give his medium actual embodiment the painter uses pigment, as oil-color or water-color or tempera, laid upon a surface, as canvas, wood, paper, plaster; this material pigment is his vehicle. The etcher employs inked scratches upon his plate of zinc or copper, bitten by acid or scratched directly by the needle; these marks of ink are the vehicle of etching. To the way in which the artist uses his medium for practical expression and to his methods in the actual handling of his vehicle is applied the term technique. The general conception of his picture, its total design, the choice of motive, the selection of details, the main scheme of composition,—these belong to the great strategy of his art. The application of these principles in practice and their material working out upon his canvas are an affair of tactics and fall within the province of technique.
