128. The first interference should be in education. In order that men may be able to support themselves when they are grown, their strength must be properly developed while they are young; and the State should always see to this--not allowing their health to be broken by too early labour, nor their powers to be wasted for want of knowledge. Some questions connected with this matter are noticed farther on under the head "trial schools": one point I must notice here, that I believe all youths, of whatever rank, ought to learn some manual trade thoroughly; for it is quite wonderful how much a man's views of life are cleared by the attainment of the capacity of doing any one thing well with his hands and arms. For a long time, what right life there was in the upper classes of Europe depended in no small degree on the necessity which each man was under of being able to fence; at this day, the most useful things which boys learn at public schools are, I believe, riding, rowing, and cricketing. But it would be far better that members of Parliament should be able to plough straight, and make a horseshoe, than only to feather oars neatly or point their toes prettily in stirrups. Then, in literary and scientific teaching, the great point of economy is to give the discipline of it through knowledge which will immediately bear on practical life. Our literary work has long been economically useless to us because too much concerned with dead languages; and our scientific work will yet, for some time, be a good deal lost, because scientific men are too fond or too vain of their systems, and waste the student's time in endeavouring to give him large views, and make him perceive interesting connections of facts; when there is not one student, no, nor one man, in a thousand, who can feel the beauty of a system, or even take it clearly into his head; but nearly all men can understand, and most will be interested in, the facts which bear on daily life. Botanists have discovered some wonderful connection between nettles and figs, which a cowboy who will never see a ripe fig in his life need not be at all troubled about; but it will be interesting to him to know what effect nettles have on hay, and what taste they will give to porridge; and it will give him nearly a new life if he can be got but once, in a spring time, to look well at the beautiful circlet of white nettle blossom, and work out with his schoolmaster the curves of its petals, and the way it is set on its central mast. So, the principle of chemical equivalents, beautiful as it is, matters far less to a peasant boy, and even to most sons of gentlemen, than their knowing how to find whether the water is wholesome in the back-kitchen cistern, or whether the seven-acre field wants sand or chalk.
