41. It is not, however, only in getting prints or woodcuts of the best kind that you will practise economy. There is a certain quality about an original drawing which you cannot get in a woodcut, and the best part of the genius of many men is only expressible in original work, whether with pen or ink--pencil or colours. This is not always the case; but in general, the best men are those who can only express themselves on paper or canvas; and you will therefore, in the long run, get most for your money by buying original work; proceeding on the principle already laid down, that the best is likely to be the cheapest in the end. Of course, original work cannot be produced under a certain cost. If you want a man to make you a drawing which takes him six days, you must, at all events, keep him for six days in bread and water, fire and lodging; that is the lowest price at which he can do it for you, but that is not very dear: and the best bargain which can possibly be made honestly in art--the very ideal of a cheap purchase to the purchaser--is the original work of a great man fed for as many days as are necessary on bread and water, or perhaps we may say with as many onions as will keep him in good humour. That is the way by which you will always get most for your money; no mechanical multiplication or ingenuity of commercial arrangements will ever get you a better penny's worth of art than that.
42. Without, however, pushing our calculations quite to this prison-discipline extreme, we may lay it down as a rule in art-economy, that original work is, on the whole, cheapest and best worth having. But precisely in proportion to the value of it as a production, becomes the importance of having it executed in permanent materials. And here we come to note the second main error of the day, that we not only ask our workmen for bad art, but we make them put it into bad substance. We have, for example, put a great quantity of genius, within the last twenty years, into water-colour drawing, and we have done this with the most reckless disregard whether either the colours or the paper will stand. In most instances, neither will. By accident, it may happen that the colours in a given drawing have been of good quality, and its paper uninjured by chemical processes. But you take not the least care to ensure these being so; I have myself seen the most destructive changes take place in water-colour drawings within twenty years after they were painted; and from all I can gather respecting the recklessness of modern paper manufacture, my belief is, that though you may still handle an Albert Dürer engraving, two hundred years old, fearlessly, not one-half of that time will have passed over your modern water-colours, before most of them will be reduced to mere white or brown rags; and your descendants, twitching them contemptuously into fragments between finger and thumb, will mutter against you, half in scorn and half in anger, "Those wretched nineteenth century people! they kept vapouring and fuming about the world, doing what they called business, and they couldn't make a sheet of paper that wasn't rotten."
