94 the full power of expressing the perspective, foreshortening and various undulation of such surface is, perhaps, the last and most difficult attainment of the hand and eye. For instance: there is, perhaps, no tree which has baffled the landscape painter more than the common black spruce fir. It is rare that we see any representation of it other than caricature. It is conceived as if it grew in one plane, or as a section of a tree, with a set of boughs symmetrically dependent on opposite sides. It is thought formal, unmanageable, and ugly. It would be so, if it grew as it is drawn. But the Power of the tree is not in that chandelier-like section. It is in the dark, flat, solid tables of leafage, which it holds out on its strong arms, curved slightly over them like shields, and spreading towards the extremity like a hand. It is vain to endeavour to paint the sharp, grassy, intricate leafage, until this ruling form has been secured; and in the boughs that approach the spectator, the foreshortening of it is like that of a wide hill country, ridge just rising over ridge in successive distances; and the finger-like extremities, foreshortened to absolute bluntness, require a delicacy in the rendering of them like that of the drawing of the hand of the Magdalene upon the vase in Mr Rogers's Titian. Get but the back of that foliage, and you have the tree; but I cannot name the artist who has thoroughly felt it. So, in all drawing and sculpture, it is the power of rounding, softly and perfectly, every inferior mass which preserves the serenity, as it follows the truth, of Nature, and which demands the highest knowledge and skill from the workman. A noble design may always be told by the back of a single leaf, and it was the sacrifice of this breadth and refinement of surface for sharp edges and extravagant undercutting, which destroyed the Gothic mouldings, as the substitution of the line for the light destroyed the Gothic tracery. This change, however, we shall better comprehend after we have glanced at the chief conditions
