In modern times the division of labour is immensely complicated: not only has every town and village its different tradespeople, and artisans and men in different posts and employments, but each district has its peculiar manufactures. In one place cotton goods are produced; in another, woollen goods; in other parts of the country flax, jute, silk are manufactured. Iron is made in Staffordshire, Cleveland, South Wales, and Scotland; copper is smelted in South Wales; crockery is baked in the potteries; hosiery is manufactured in Nottingham and Leicester; linens are sewed in the North of Ireland; and so on. In every separate factory, again, there is division of labour; there is the manager, the chief clerk, the assistant clerks; the foremen of different departments, the timekeeper, the engine-tenter, and stokers, the common labourers, the carters, errand boys, porters, &c., all in addition to the actual mechanics of different kinds and ranks who do the principal work. Thus the division of labour spreads itself throughout the whole of society, from the Queen and her Ministers, down to the errand boy, or the street scavenger. #26. Adam Smith on the Division of Labour.# There are many ways in which we gain by the division of labour, but Adam Smith has treated the subject so excellently that we had better, in the first place, consider his view of the matter. There are, as he thought, three ways in which advantage arises from the division of labour, namely-- (1.) Increase of dexterity in every particular workman. (2.) Saving of the time which is commonly lost in passing from one kind of work to another. (3.) The invention of a great number of machines, which facilitate and abridge labour, and enable one man to do the work of many. There can be no doubt as to the #increase of dexterity#, which arises from practice. Any one who has tried to imitate a juggler, or to play the piano, without having learned to do it, knows how absurdly he fails. Nobody could possibly do the work of a glass-blower without long practice. Even when a man can do a job in some sort of way, he will do it much more quickly if he does it often. Adam Smith states that if a blacksmith had to make nails without having been accustomed to the work, he would not make above 200 or 300 bad nails in a day. With practice he might learn to make 800 or 1000 nails in a day; but boys who are brought up to the nailer's trade can turn out 2300 nails of the same kind in the same time. But there is no need of many examples: everything that we see well or quickly made has been made by men who have spent a great deal of time and trouble in learning and practising the work.
