Now is this perpetual consistency in all points, this concentration of every fact which can possibly bear upon what we are to be told, this watchfulness of the entire meaning and system [§ 13. His consistency in every minor feature.]of nature, which fills every part and space of the picture with coincidences of witness, which come out upon us, as they would from the reality, more fully and deeply in proportion to the knowledge we possess and the attention we give, admirable or not? I could go on writing page after page on every sky of Turner's, and pointing out fresh truths in every one. In the Havre, for instance, of the Rivers of France we have a new fact pointed out to us with respect to these cirri, namely, their being so faint and transparent as not to be distinguishable from the blue of the sky, (a frequent case,) except in the course of a sunbeam, which, however, does not illumine their edges, they being not solid enough to reflect light, but penetrates their whole substance, and renders them flat, luminous forms in its path, instantly and totally lost at its edge. And thus a separate essay would be required by every picture, to make fully understood the new phenomena which it treated and illustrated. But after once showing what are the prevailing characteristics of these clouds, we can only leave it to the reader to trace them wherever they occur. There are some fine and characteristic passages of this kind of cloud given by Stanfield, though he dares not use them in multitude, and is wanting in those refined qualities of form which it is totally impossible to explain in words, but which, perhaps, by simple outlines, on a large scale, selected from the cloud forms of various artists, I may in following portions of the work illustrate with the pencil.

Of the colors of these clouds I have spoken before, (Sec. I. Chap. II.;) but though I then alluded to their purity and vividness, I scarcely took proper notice of their variety; there is [§ 14. The color of the upper clouds.]indeed in nature variety in all things, and it would be absurd to insist on it in each case, yet the colors of these clouds are so marvellous in their changefulness, that they require particular notice. If you watch for the next sunset, when there are a considerable number of these cirri in the sky, you will see, especially at the zenith, that the sky does not remain of the same color for two inches together; one cloud has a dark side of cold blue, and a fringe of milky white; another, above it, has a dark side of purple and an edge of red; another, nearer the sun, has an under-side of orange and an edge of gold; these you will find mingled with, and passing into the blue of the sky, which in places you will not be able to distinguish from the cool gray of the darker clouds, and which will be itself full of gradation, now pure and deep, now faint and feeble; and all this is done, not in large pieces, nor on a large scale, but over and over again in every square yard, so that there is no single part nor portion of the whole sky which has not in itself variety of color enough for a separate picture, and yet no single part which is like another, or which has not some peculiar source of beauty, and some peculiar arrangement of color of its own. Now, instead of this, you get in the old masters—Cuyp, or Claude, or whoever they may be—a field of blue, delicately, beautifully, and uniformly shaded down to the yellow sun, with a certain number of similar clouds, each with a dark side of the same gray, and an edge of the same yellow. I do not say that nature never does anything like this, but I say that her principle is to do a great deal more, and that what she does more than this,—what I have above described, and what you may see in nine sunsets out of ten,—has been observed, attempted, and rendered by Turner only, and by him with a fidelity and force which presents us with more essential truth, and more clear expression and illustration of natural laws, in every wreath of vapor, than composed the whole stock of heavenly information, which lasted Cuyp and Claude their lives.

We close then our present consideration of the upper clouds, to return to them when we know what is beautiful; we have at present only to remember that of these clouds, and the truths [§ 15. Recapitulation.]connected with them, none before Turner had taken any notice whatsoever; that had they therefore been even feebly and imperfectly represented by him, they would yet have given him a claim to be considered more extended and universal in his statement of truths than any of his predecessors; how much more when we find that deep fidelity in his studied and perfect skies which opens new sources of delight to every advancement of our knowledge, and to every added moment of our contemplation.


[31] I use this work frequently for illustration, because it is the only one I know in which the engraver has worked with delicacy enough to give the real forms and touches of Turner. I can reason from these plates, (in questions of form only,) nearly as well as I could from the drawings.


CHAPTER III.

OF TRUTH OF CLOUDS:—SECONDLY, OF THE CENTRAL CLOUD
REGION.

We have next to investigate the character of the Central Cloud Region, which I consider as including all clouds which are the usual characteristic of ordinary serene weather, and [§ 1. Extent and typical character of the central cloud region.]which touch and envelop the mountains of Switzerland, but never affect those of our own island; they may therefore be considered as occupying a space of air ten thousand feet in height, extending from five to fifteen thousand feet above the sea.
