198. The third and last distinctive attribute is sensuality. This is a startling word, and requires some explanation. In the first place, every line is voluptuous, floating, and wavy in its form; deep, rich, and exquisitely soft in its color; drowsy in its effect; like slow wild music; letting the eye repose on it, as on a wreath of cloud, without one feature of harshness to hurt, or of contrast to awaken. In the second place, the cultivation, which, in the simple blue country, has the forced formality of growth which evidently is to supply the necessities of man, here seems to leap into the spontaneous luxuriance of life, which is fitted to minister to his pleasures. The surface of the earth exults with animation, especially tending to the gratification of the senses; and, without the artificialness which reminds man of the necessity of his own labor, without the opposing influences which call for his resistance, without the vast energies that remind him of his impotence, without the sublimity that can call his noblest thoughts into action, yet, with every perfection that can tempt him to indolence of enjoyment, and with such abundant bestowal of natural gifts, as might seem to prevent that indolence from being its own punishment, the earth appears to have become a garden of delight, wherein the sweep of the bright hills, without chasm or crag, the flow of the bending rivers, without rock or rapid, and the fruitfulness of the fair earth, without care or labor on the part of its inhabitants, appeal to the most pleasant passions of eye and sense, calling for no effort of body, and impressing no fear on the mind. In hill country we have a struggle to maintain with the elements; in simple blue, we have not the luxuriance of delight: here, and here only, all nature combines to breathe over us a lulling slumber, through which life degenerates into sensation.
