Sharpness need not be hardness; on the contrary, sharpness and softness can be harmoniously combined in the representation of any object desired. On the other hand, a subject may possess abundance of detail, and yet convey to the mind an idea of _hardness_ which the artist did not intend. This kind of hardness I should attribute to a miscarriage of thought, or a failure, from want of manipulative skill, to produce the desired effect. For example: one artist will paint a head, model it carefully, and carry out all the gradations of light and shade, and for all that it will be _hard_--hard as stone, resembling the transcript of a painted statue more than flesh. With the same brushes and colours another artist will paint a head that may be no better in its drawing, nor any more correct in its light and shade, but it will resemble _flesh_, and convey to the mind of the observer a correct impression of the substance represented--its flexibility and elasticity--that it is something that would be warm and pleasant to the touch, and not make you recoil from it as if it were something cold, hard, and repulsive, as in the former case. Again, two artists will paint a fabric or an article of furniture (say a table) with the same brushes, pigments, and mediums: the one artist will render it so faithfully in every respect that it would suggest to the mind the dull sound peculiar to wood when struck, and not the sharp, clear ring of metal which the work of the other artist would suggest. Another example: one artist paints a feather, and it appears to have all the feathery lightness and characteristics of the natural object; the other will paint it the same size, form, and colour, and yet it will be more like a painted chip, wanting the downy texture and float-in-the-air suggestiveness of the other. Thus it will be seen that both artists had similar ideas, had similar materials and means at their disposal to render on canvas the same or similar effects. The one succeeded, and the other failed, in giving a faithful rendering of the same subjects; but it was no fault in the materials with which they worked. The works of one artist will convey to the mind an idea of the thing itself; with its texture, properties, weight, and proportions; nothing undervalued; nothing overrated, nothing softer, nothing harder, than the thing in nature intended to be portrayed. The other gives the same idea of form and size, light and shade, and colour, but not the texture; it is something harder, as iron instead of wood, or hard wood instead of soft wood, or stone instead of flesh. This, then, is the artistic meaning of hardness (or concentration, as Mr. Wall said), and that is an apparent packing together, a compression or petrifaction of the atoms or fibre of which the natural materials are composed. This difference in the works of artists is simply the effects of _feeling_, of power over the materials employed, and ability to transfer to canvas effects that are
