I do not mean, however, that copies should never be made. A certain number of dull persons should always be employed by a Government in making the most accurate copies possible of all good pictures; these copies, though artistically valueless, would be historically and documentarily valuable, in the event of the destruction of the original picture. The studies also made by great artists for their own use, should be sought after with the greatest eagerness; they are often to be bought cheap; and in connection with the mechanical copies, would become very precious: tracings from frescos and other large works are also of great value; for though a tracing is liable to just as many mistakes as a copy, the mistakes in a tracing are of one kind only, which may be allowed for, but the mistakes of a common copyist are of all conceivable kinds: finally, engravings, in so far as they convey certain facts about the pictures, without pretending adequately to represent or give an idea of the pictures, are often serviceable and valuable. I can't, of course, enter into details in these matters just now; only this main piece of advice I can safely give you--never to buy copies of pictures (for your private possession) which pretend to give a _facsimile_ that shall be in any wise representative of, or equal to, the original. Whenever you do so, you are only lowering your taste, and wasting your money. And if you are generous and wise, you will be ready rather to subscribe as much as you would have given for a copy of a great picture, towards its purchase, or the purchase of some other like it, by the nation. There ought to be a great National Society instituted for the purchase of pictures; presenting them to the various galleries in our great cities, and watching there over their safety: but in the meantime, you can always act safely and beneficially by merely allowing your artist friends to buy pictures for you, when they see good ones. Never buy for yourselves, nor go to the foreign dealers; but let any painter whom you know be entrusted, when he finds a neglected old picture in an old house, to try if he cannot get it for you; then, if you like it, keep it; if not, send it to the hammer, and you will find that you do not lose money on pictures so purchased. And the third and chief practical outcome of the matter is this general one: Wherever you go, whatever you do, act more for _preservation_ and less for _production_. I assure you, the world is, generally speaking, in calamitous disorder, and just because you have managed to thrust some of the lumber aside, and get an available corner for yourselves, you think you should do nothing but sit spinning in it all day long--while, as householders and economists, your first thought and effort should be, to set things more square all about you. Try to set the ground floors in order, and get the rottenness out of your granaries. _Then_ sit and spin, but not till then.
