From the moment that the industry of this country began to work with security, and capital and labour applied themselves in union--perhaps not a perfect union, but still in union--to the great business of production, they worked with less and less expenditure of unprofitable labour. They continued to labour more and more profitably, as they laboured with knowledge. The labour of all rude nations, and of all uncultivated individuals, is labour with ignorance. Peter the wild boy, whom we have already mentioned, could never be made to perceive the right direction of labour, because he could not trace it through its circuitous courses for the production of utility. He would work under control, but, if left to himself, he would not work profitably. Having been trusted to fill a cart with manure, he laboured with diligence till the work was accomplished; but no one being at hand to direct him, he set to work as diligently to unload the cart again. He thought, as too many think even now, that the good was in the labour, and not in the results of the labour. The same ignorance exhibits itself in the unprofitable labour and unprofitable application of capital, even of persons far removed beyond the half-idiocy of Peter the wild boy. In the thirteenth century many of the provinces of France were overrun with rats, and the people, instead of vigorously hunting the rats, were persuaded to carry on a process against them in the ecclesiastical courts; and there, after the cause of the injured people and the injuring rats was solemnly debated, the rats were declared cursed and excommunicated if they did not retire in six days. The historian does not add that the rats obeyed the injunction; and doubtless the farmers were less prepared to resort to the profitable labour of chasing them to death when they had paid the ecclesiastics for the unprofitable labour of their excommunication. There is a curious instance of unprofitable labour given in a book on the Coal Trade of Scotland, written as recently as 1812. The people of Edinburgh had a passion for buying their coals in immense lumps, and, to gratify this passion, the greatest care was taken not to break the coals in any of the operations of conveying them from the pit to the cellar of the consumer. A wall of coals was first built within the pit, another wall under the pit's mouth, another wall when they were raised from the pit, another wall in the waggon which conveyed them to the port where they were shipped, another wall in the hold of the ship, another wall in the cart which conveyed them to the consumer, and another wall in the consumer's cellar; and the result of these seven different buildings-up and takings-down was, that after the consumer had paid thirty per cent. more for these square masses of coal than for coal shovelled together in large and small pieces, his servant had daily to break the large coals to bits to enable him to make any use of them.
