But if, holding fast his first thought, he finds other ideas insensibly gathering to it, and, whether he will or not, modifying it into something which is not so much the image of the place itself, as the spirit of the place, let him yield to such fancies, and follow them wherever they lead. For, though error on this side is very rare among us in these days, it _is_ possible to check these finer thoughts by mathematical accuracies, so as materially to impair the imaginative faculty. I shall be able to explain this better after we have traced the actual operation of Turner's mind on the scene under discussion. Sec. 13. Turner was always from his youth fond of stones (we shall see presently why). Whether large or small, loose or embedded, hewn into cubes or worn into boulders, he loved them as much as William Hunt loves pineapples and plums. So that this great litter of fallen stones, which to any one else would have been simply disagreeable, was to Turner much the same as if the whole valley had been filled with plums and pineapples, and delighted him exceedingly, much more than even the gorge of Dazio Grande just above. But that gorge had its effect upon him also, and was still not well out of his head when the diligence stopped at the bottom of the hill, just at that turn of the road on the right of the bridge; which favorable opportunity Turner seized to make what he called a "memorandum" of the place, composed of a few pencil scratches on a bit of thin paper, that would roll up with others of the sort and go into his pocket afterwards. These pencil scratches he put a few blots of color upon (I suppose at Bellinzona the same evening, certainly _not_ upon the spot), and showed me this blotted sketch when he came home. I asked him to make me a drawing of it, which he did, and casually told me afterwards (a rare thing for him to do) that he liked the drawing he had made. Of this drawing I have etched a reduced outline in Plate +21+. Sec. 14. In which, primarily, observe that the whole place is altered in scale, and brought up to the general majesty of the higher forms of the Alps. It will be seen that, in my topographical sketch, there are a few trees rooted in the rock on this side of the gallery, showing by comparison, that it is not above four or five hundred feet high. These trees Turner cuts away, and gives the rock a height of about a thousand feet, so as to imply more power and danger in the avalanche coming down the couloir.
