rated in some small degree by each use, it does not do its. work by being deteriorated, as the coal and the fleece do theirs by being destroyed; on the contrary, it is the better instrument the better it resists deterioration. There are some things, rightly classed as materials, which may be used as such a second and a third time, but not while the product to which they at first contributed remains in existence. The iron which formed a tank or a set of pipes may be melted to form a plough or a steam-engine; the stones with which a house was built may be used after it is pulled down, to build another. But this cannot be done while the original product subsists; their function as materials is suspended, until the exhaustion of the first use. Not so with the things classed as implements; they may be used repeatedly for fresh work, until the time, sometimes very distant, at which they are worn out, while the work already done by them may subsist unimpaired, and when it perishes, does so by its own laws, or by casualties of its own.*

The only practical difference of much importance arising from the distinction between materials and implements, is one which has attracted our attention in another case. Since materials are destroyed as such by being once used, the whole of the labour required for their production, as well as the abstinence of the person who supplied the means for carrying it on, must be remunerated from the fruits of that single use. Implements, on the contrary, being susceptible of repeated employment, the whole of the products

*The able and friendly reviewer of this treatise in the Edinburgh Review (October, 1848) states the distinction between materials and implements rather differently: proposing to consider as materials "all the things which, after having undergone the change implied in production, are themselves matter of exchange," and as implements (or instruments) "the things which are employed in producing that change, but do not themselves become part of the exchangeable result." According to these definitions, the fuel consumed in a manufactory would be considered, not as a material, but as an instrument. This use of the terms accords better than that proposed in the text, with the primitive physical meaning of the word "material;" but the distinction on which it is grounded is one almost irrelevant to political economy.

which they are instrumental in bringing into existence are a fund which can be drawn upon to remunerate the labour of their construction, and the abstinence of those by whose accumulations that labour was supported. It is enough if each product contributes a fraction, commonly an insignificant one, towards the remuneration of that labour and abstinence, or towards indemnifying the immediate producer for advancing that remuneration to the person who produced the tools.

§ 5. Thirdly: Besides materials for industry to employ itself on, and implements to aid it, provision must be made to prevent its operations from being disturbed and its products injured, either by the destroying agencies of nature, or by the violence or rapacity of men. This gives rise to another mode in which labour not employed directly about the product itself, is instrumental to its production; namely, when employed for the protection of industry. Such is the object of all buildings for industrial purposes; all manufactories, warehouses, docks, granaries, barns, farm-buildings devoted to cattle, or to the operations of agricultural labour. I exclude those in which the labourers live, or which are destined for their personal accommodation: these, like their food, supply actual wants, and must be counted. in the remuneration of their labour. There are many modes in which labour is still more directly applied to the protection of productive operations.

The herdsman has little other occupation than to protect the cattle from harm: the positive agencies concerned in the realization of the product, go on nearly of themselves. I have already mentioned the labour of the hedger and ditcher, of the builder of walls or dykes. To these must be added that of the soldier, the policeman, and the judge. These functionaries are not indeed employed exclusively in the protection of industry, nor does their payment constitute, to the individual producer, a part of the expenses of production. But they are paid from the taxes, which are

derived from the produce of industry; and in any tolerably governed country they render to its operations a service far more than equivalent to the cost. To society at large they are therefore part of the expenses of production; and if the returns to production were not sufficient to maintain these labourers in addition to all the others required, production, at least in that form and manner, could not take place. Besides, if the protection which the government affords to the operations of industry were not afforded, the producers would be under a necessity of either withdrawing a large share of their time and labour from production, to employ it in defence, or of engaging armed men to defend them; all which labour, in that case, must be directly remunerated from the produce; and things which could not pay for this additional labour, would not be produced. Under the present arrangements, the product pays its quota towards the same protection, and notwithstanding the waste and prodigality incident to government expenditure, obtains it of better quality at a much smaller cost.

§ 6. Fourthly: There is a very great amount of labour employed, not in bringing the product into existence, but in rendering it, when in existence, accessible to those for whose use it is intended. Many important classes of labourers find their sole employment in some function of this kind. There is first the whole class of carriers, by land or water: muleteers, waggoners, bargemen, sailors, wharfmen, coalheavers, porters, railway establishments, and the like. Next, there are the constructors of all the implements of transport; ships, barges, carts, locomotives, &c., to which must be added roads, canals, and railways. Roads are sometimes made by the government, and opened gratuitously to the public; but the labour of making them is not the less paid for from the produce. Each producer, in paying his quota of the taxes levied generally for the construction of roads, pays for the use of those which conduce to his convenience; and if made with any tolerable judgment, they

increase the returns to his industry by far more than an equivalent amount.

Another numerous class of labourers employed in rendering the things produced accessible to their intended consumers, is the class of dealers and traders, or, as they may be termed, distributors. There would be a great waste of time and trouble, and an inconvenience often amounting to impracticability, if consumers could only obtain the articles they want by treating directly with the producers. Both producers and consumers are too much scattered, and the latter often at too great a distance from the former. To diminish this loss of time and labour, the contrivance of fairs and markets was early had recourse to, where consumers and producers might periodically meet, without any intermediate agency; and this plan answers tolerably well for many articles, especially agricultural produce, agriculturists having at some seasons a certain quantity of spare time on their hands. But even in this case, attendance is often very troublesome and inconvenient to buyers who have other occupations, and do not live in the immediate vicinity; while, for all articles the production of which requires continuous attention from the producers, these periodical markets must be held at such considerable intervals, and the wants of the consumers must either be provided for so long beforehand, or must remain so long unsupplied, that even before the resources of society admitted of the establishment of shops, the supply of these wants fell universally into the hands of itinerant dealers; the pedlar, who might appear once a month, being preferred to the fair, which only returned once or twice a year. In country districts, remote from towns or large villages, the industry of the pedlar is not yet wholly superseded. But a dealer who has a fixed abode and fixed customers is so much more to be depended on, that consumers prefer resorting to him if he is conveniently accessible; and dealers therefore find their advantage in establishing themselves in every locality where

there are sufficient consumers near at hand to afford them a remuneration.

In many cases the producers and dealers are the same persons, at least as to the ownership of the funds and the control of the operations. The tailor, the shoemaker, the baker, and many other tradesmen, are the producers of the articles they deal in, so far as regards the last stage in the production. This union, however, of the functions of manufacturer and retailer, is only expedient when the article can advantageously be made at or near the place convenient for retailing it; and is, besides, manufactured and sold in small parcels. When things have to be brought from a distance, the same person cannot effectually superintend both the making and the retailing of them; when they are best and most cheaply made on a large scale, a single manufactory requires so many local channels to carry off its supply, that the retailing is most conveniently delegated to other agency and even shoes and coats, when they are to be furnished in large quantities at once, as for the supply of a regiment or of a workhouse, are usually obtained not directly from the producers, but from intermediate dealers, who make it their business to ascertain from what producers they can be obtained best and cheapest. Even when things are destined to be at last sold by retail, convenience soon creates a class of wholesale dealers. When products and transactions have multiplied beyond a certain point; when one manufactory supplies many shops, and one shop has often to obtain goods from many different manufactories, the loss of time and trouble both to the manufacturers and to the retailers by treating directly with one another, makes it more convenient to them to treat with a smaller number of great dealers or merchants, who only buy to sell again, collecting goods from the various producers, and distributing them to the retailers, to be by them further distributed among the consumers. Of these various elements is composed the Distributing Class, whose agency is supplementary to that of the Producing Class: and the produce so
