30. There are many other points of nearly as much importance as these, to be explained with reference to the development of genius; but I should have to ask you to come and hear six lectures instead of two if I were to go into their detail. For instance, I have not spoken of the way in which you ought to look for those artificers in various manual trades, who, without possessing the order of genius which you would desire to devote to higher purposes, yet possess wit, and humour, and sense of colour, and fancy for form--all commercially valuable as quantities of intellect, and all more or less expressible in the lower arts of iron-work, pottery, decorative sculpture, and such like. But these details, interesting as they are, I must commend to your own consideration, or leave for some future inquiry. I want just now only to set the bearings of the entire subject broadly before you, with enough of detailed illustration to make it intelligible; and therefore I must quit the first head of it here, and pass to the second--namely, how best to employ the genius we discover. A certain quantity of able hands and heads being placed at our disposal, what shall we most advisably set them upon? 31. II. APPLICATION.--There are three main points the economist has to attend to in this. First, To set his men to various work. Secondly, To easy work. Thirdly, To lasting work. I shall briefly touch on the first two, for I want to arrest your attention on the last. 32. I say first to various work. Supposing you have two men of equal power as landscape painters--and both of them have an hour at your disposal. You would not set them both to paint the same piece of landscape. You would, of course, rather have two subjects than a repetition of one.
