Another and a totally different kind of combination of labour arises when men arrange to assist each other in doing the same work. Thus, sailors pulling at the same rope combine their labour together; other instances are, carrying the same ladder, rowing the same boat, and so forth. In this case there is said to be #simple combination of labour#, because the men do the same sort of work. When the men have different operations to perform, there is said to be #complex combination of labour#, as when one man points a pin and another makes the head. On board a ship there is both simple and complex combination. When several men work at the same capstan the combination is simple, because one man does exactly the same as the others. But the captain, mate, steersman, carpenter, boatswain, and cook work together in complex combination, since each attends to his own proper duties. Similarly, in a company of soldiers the privates act together in simple combination, but the officers of different ranks have distinct duties to perform, so that the combination becomes complex. Men who thus assist each other are usually able to do far more work than if they acted separately. #32. Disadvantages of the Division of Labour.# There are certainly some evils which arise out of the great division of labour now existing in civilised countries. These evils are of no account compared with the immense benefits which we receive; still it is well to notice them. In the first place, #division of labour tends to make a man's power narrow and restricted#; he does one kind of work so constantly, that he has no time to learn and practice other kinds of work. A man becomes, as it has been said, worth only the tenth part of a pin; that is, there are men who know only how to make, for instance, the head of a pin. In the time of the Romans it was said, _ne sutor ultra crepidam_, let not the shoemaker go beyond his last. When a man accustomed only to making pins or shoes goes into the far west states of America, he finds himself unfitted for doing all the kinds of hard work required from a settler. The poor peasant from Norway or Sweden, who seems at first sight a less intelligent man, is able to build his own house, till the ground, tend his horse, and in a rough way, make his own carts, implements, and household furniture. Even the Red Indian is much better able to take care of himself in a new country than the educated mechanic. The only thing to be said is that the skilled shoemaker, or mechanic of whatever sort, must endeavour to keep to the trade which he has learnt so well. It is a misfortune both for himself and for other people if he is obliged to undertake work which he cannot do so well.
