The Principles of Political Economy

more remote. All these persons ultimately derive the remuneration of their labour from the bread, or its price: the plough-maker as much as the rest; for since ploughs are of no use except for tilling the soil, no one would make or use ploughs for any other reason than because the increased returns, thereby obtained from the ground, afforded a source from which an adequate equivalent could be assigned for the labour of the plough-maker. If the produce is to be used or consumed in the form of bread, it is from the bread that this equivalent must come. The bread must suffice to remunerate all these labourers, and several others; such as the carpenters and bricklayers who erected the farm-buildings; the hedgers and ditchers who made the fences necessary for the protection of the crop; the miners and smelters who extracted or prepared the iron of which the plough and other instruments were made. These, however, and the plough-maker, do not depend for their remuneration upon the bread made from the produce of a single har

nto a region of factions too minute for calculation. Suppose, for instance, that the same plough will last, before being worn out, a dozen years. Only one-twelfth of the labour of making the plough must be placed to the account of each year's harvest. A twelfth part of the labour of making a plough is an appreciable quantity. But the same set of tools, perhaps, suffice to the plough-maker for forging a hundred ploughs, which serve during the twelve years of their existence to prepare the soil of as many different farms. A twelve-hundredth part of the

work, possesses a store of food, or can obtain access to the stores of some one else, in sufficient quantity to maintain him until the production is completed, he can undertake no labour but such as can be carried on at odd intervals, concurrently with the pursuit of his subsistence. He cannot obtain food itself in any abundance; for every mode of so obtaining it, requires that there be already food in store. Agriculture only brings forth food after the lapse of months; and though the labours of the agriculturist are not necessarily continuous during the whole period, they must occupy a considerable part of it. Not only is agriculture impossible

abour that produced the food which fed all these labourers, is as necessary to the ultimate result, the bread of the present harvest, as any of those other portions of labour; but is not, like them, remunerated from it. That previous labour has received its remuneration from the previous food. In order to raise any product, there are needed labour, tools, and materials, and food to feed the labourers. But the tools and materials are of no use except for obtaining the product, or at least are to be applied to no other use, and the labour of their construction can be remunerated only from the product wh

. He will look for some equivalent for this forbearance: he will expect his advance of food to come back to him with an increase, called in the language of business, a profit; and the hope of this profit will generally have been a part of the inducement which made him accumulate a stock, by economizing in his own consumption; or, at any rate, which made him forego the application of it, when accumulated, to his personal ease or satisfaction. The food also which maintained other workmen while producing the tools or materials, must have been provided in advance by some one, and he, too, must have his profit from the ultimate product; but there is this difference, that here the ultimate product has to supply not only the pro

t include the labour of producing subsistence or other necessaries of life to be consumed by productive labourers; for the main end and purpose of this labour is the subsistence itself; and though the pos

ted for human use. Extractive industry, however, is not confined to the extraction of materials. Coal, for instance, is employed, not only in the process of industry, but in directly warming human beings. When so used, it is not a material of production, but is itself the ultimate product. So, also, in the case of a mine of precious stones. These are to some smal

or wood for the purposes of the carpenter's or any other art. In the forests of America, Norway, Germany, the Pyrenees and Alps, this sort of labour

rse-hair, and the like. The things used as materials in some process or other of manufacture are of a most miscellaneous character, drawn from almost every quarter of the animal, vegetable, and mineral kingdoms. And besides this, the finished products of many branches of industry are the materials of others. The thread produced by the spinner is applied to hardly any use except as material for the weaver. Even the product of the loom is chie

mplements or in that of materials. Perhaps the line is most usually and most conveniently drawn, by considering as a material every instrument of production which can only be used once, being destroyed (at least as an instrument for the purpose in hand) by a single employment. Thus fuel, once burnt, cannot be again used as fuel; what can be so used is only any portion which has remained unburnt the first time. And not only it cannot be used without being consumed, but it is only useful by being consumed; for if no part of the fuel were destroyed, no heat would be generated. A fleece, again, is destroyed as a fleece by being spun into thread; and the thread cannot be used as thread when woven into cloth. But an axe is not destroyed as an axe by cutting down a tree: it may be used afterwards to cut down a hundred or a thousand more; and though deteriorated in some small degree by each use, it does not do its work by being deteriorated, as

plied 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 which they are instrumental in bringing into existence are a fund which can be drawn upon to remunerate the labour of their construction, and

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 expense

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 publi

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 societ

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

d strength which enable him to become a labourer in his turn. To the community at large, the labour and expense of rearing its infant population form a part of the outlay which is a condition of production, and which is to be replaced with increase from the future produce of their labour. By the individuals, this labour and expense are usually incurred from other motives than to obtain such ultimate return, and, for most purposes of political economy, need not be taken into account as expenses of producti

erve from perishing by death or infirmity that portion of the productive resources of society which is fixed in the lives and bodily or mental powers of its productive members. To the individuals, indeed, this forms but a part, sometimes an imperceptible part, of the motives that induce them to submit to medical treatment: it is not principally from economical motives that persons have a limb amputated, or endeavour to be cured of a fever, though when they do so, there is generally sufficient inducement for it even on that score alone

t somebody to drive and watch him. On the other hand, there is some bodily ingredient in the labour most purely mental, when it generates any external result. Newton could not have produced the Principia without the bodily exertion either of penmanship or of dictation; and he must have drawn many diagrams, and written out many calculations and demonstrations, while he was preparing it in his mind. Inventors, besides the labour of their brains, generally go through much labour with their hands, in the models which they construct and the experiments they have to make before their idea can realize itself successfully in act. Whether mental, however, or bodily, their labour is a part of that by which the pr

ative and apparently merely curious enquiry, by the mathematicians of Alexandria, into the properties of three curves formed by the intersection of a plane surface and a cone. No limit can be set to the importance, even in a purely productive and material point of view, of mere thought. Inasmuch, however, as these material fruits, though the result, are seldom the direct purpose of the pursuits of savants, nor is their remuneration in general derived from the increased production which may be caused incidentally, and mostly after a long interval, by their discoveries; this ultimate influence does not, for most of the purposes of polit

akers of butter and cheese; operations always counted as agricultural, probably because it is the custom for them to be performed by persons resident on the farm, and under the same superintendence as tillage. For many purposes all these persons, the miller and baker inclusive, must be placed in the same class with ploughmen and reapers. They are all concerned in producing food, and depend for their remuneration on the food produced; when the one class abounds and flourishes, the others do so too; they form collectively the "agricultural interest;" they render but one service to the community by their united labours, and are paid from one common source. Even the tillers of the soil, again, when the produce is not food, but the materials of what are commonly termed manufactures, belong in many respects to the same division in the economy of society as manufacturers.
