unskilled labour, there is such a thing as task-work, or working by the piece: and the superior efficiency of this is so well known, that judicious employers always resort to it when the work admits of being put out in definite portions, without the necessity of too troublesome a surveillance to guard against inferiority in the execution. In the case of the managers of joint stock companies, and of the superintending and controlling officers in many private establishments, it is a common enough practice to connect their pecuniary interest with the interest of their employers, by giving them part of their remuneration in the form of a percentage on the profits. The personal interest thus given to hired servants is not comparable in intensity to that of the owner of the capital; but it is sufficient to be a very material stimulus to zeal and carefulness, and, when added to the advantage of superior intelligence, often raises the quality of the service much above that which the generality of masters are capable of rendering to themselves. The ulterior extensions of which this principle of remuneration is susceptible, being of great social as well as economical importance, will be more particularly adverted to in a subsequent stage of the present inquiry. As I have already remarked of large establishments generally, when compared with small ones, whenever competition is free its results will show whether individual or joint stock agency is best adapted to the particular case, since that which is most efficient and most economical will always in the end succeed in underselling the other.
§ 3. The possibility of substituting the large system of production for the small, depends, of course, in the first place, on the extent of the market. The large system can only be advantageous when a large amount of business is to be done: it implies, therefore, either a populous and flourishing community, or a great opening for exportation. Again, this as well as every other change in the system of production is greatly favoured by a progressive condition of capital. It is chiefly when the capital of a country is receiving a great
