scratch with it! it is as easy as lying. Or if you think that too difficult, take an easier piece;--take either of the light sprays of foliage that rise against the fortress on the right, put your glass over them--look how their fine outline is first drawn, leaf by leaf; then how the distant rock is put in between, with broken lines, mostly stopping before they touch the leaf outline, and--again, I pray you, do it yourself; if not on that scale, on a larger. Go on into the hollows of the distant rock--traverse its thickets--number its towers--count how many lines there are in a laurel bush--in an arch--in a casement: some hundred and fifty, or two hundred, deliberately drawn lines, you will find, in every square quarter of an inch;--say three thousand to the inch,--each with skillful intent put in its place! and then consider what the ordinary sketcher's work must appear to the men who have been trained to this! 57. "But might not more have been done by three thousand lines to a square inch?" you will perhaps ask. Well, possibly. It may be with lines as with soldiers: three hundred, knowing their work thoroughly, may be stronger than three thousand less sure of their game. We shall have to press close home this question about numbers and purpose presently;--it is not the question now. Supposing certain results required,--atmospheric effects, surface textures, transparencies of shade, confusions of light,--more could _not_ be done with less. There are engravings of this modern school, of which, with respect to their particular aim, it may be said, most truly, they "_cannot_ be better done."
