To be a complete carriage constructor a man ought to be familiar with all the branches before alluded to. But there are few mechanics of such universal knowledge, and still rarer is it that they combine such knowledge with taste. Even it would be scarcely possible for a single individual to carry on a large business and do everything in his own factory. It would require a very large capital and very large premises, and also an extensive mercantile knowledge and skill—which last is based on qualities the direct opposite of those which nourish the faculty of taste. Mercantile skill depends on calculation; taste is a combination of imagination and observation. There are three modes in which carriage-building on a large scale may be successfully conducted: first, by a single individual whose only business is to combine parts, and who employs tradesmen for every separate branch; secondly, by a single individual, who employs responsible superintendents in every branch at high salaries; and, thirdly, by a combination of partners, one possessing taste, another mechanical knowledge, a third mercantile knowledge, and so on. This last mode would assuredly produce the most certain result, provided the partners possessed the necessary moral qualities to assure the absence of suspicion, jealousy, &c., amongst themselves. If these evil qualities existed they would destroy unanimity, and thus render the business unproductive by preventing efficient arrangements. It is probable that at a future time the workmen themselves will enter into some such combination, but it must be after the lapse of many years, as the principle of caste must be first eradicated amongst them, which is at present so fruitful a source of jealousy amongst the different branches. Ere that takes place the increasing plenty of capital will probably induce many capitalists to invest money in carriage-building, as they now do in house-building, giving shares and salaries to men of undoubted skill and probity in order to insure efficiency and perseverance. CHAPTER XVI. REMARKS ON KEEPING CARRIAGES. With very few exceptions, it is to be supposed that the greater number of those who can afford to indulge in the luxury of carriages are desirous of enjoying them on the most economical terms consistent with good taste, not merely as an economy of money, but also of time and convenience.
