As the accumulation of stock is previously necessary for carrying on this great improvement in the productive powers of labour, so that accumulation naturally leads to this improvement. The person who employs his stock in maintaining labour, necessarily wishes to employ it in such a manner as to produce as great a quantity of work as possible. He endeavours, therefore, both to make among his workmen the most proper distribution of employment, and to furnish them with the best machines which he can either invent or afford to purchase. His abilities, in both these respects, are generally in proportion to the extent of his stock, or to the number of people whom it can employ. The quantity of industry, therefore, not only increases in every country with the increase of the stock which employs it, but, in consequence of that increase, the same quantity of industry produces a much greater quantity of work.
Such are in general the effects of the increase of stock upon industry and its productive powers.
In the following book, I have endeavoured to explain the nature of stock, the effects of its accumulation into capital of different kinds, and the effects of the different employments of those capitals. This book is divided into five chapters. In the first chapter, I have endeavoured to shew what are the different parts or branches into which the stock, either of an individual, or of a great society, naturally divides itself. In the second, I have endeavoured to explain the nature and operation of money, considered as a particular branch of the general stock of the society. The stock which is accumulated into a capital, may either be employed by the person to whom it belongs, or it may be lent to some other person. In the third and fourth chapters, I have endeavoured to examine the manner in which it operates in both these situations. The fifth and last chapter treats of the different effects which the different employments of capital immediately produce upon the quantity, both of national industry, and of the annual produce of land and labour.
CHAPTER I.
OF THE DIVISION OF STOCK.
When the stock which a man possesses is no more than sufficient to maintain him for a few days or a few weeks, he seldom thinks of deriving any revenue from it. He consumes it as sparingly as he can, and endeavours, by his labour, to acquire something which may supply its place before it be consumed altogether. His revenue is, in this case, derived from his labour only. This is the state of the greater part of the labouring poor in all countries.
But when he possesses stock sufficient to maintain him for months or years, he naturally endeavours to derive a revenue from the greater part of it, reserving only so much for his immediate consumption as may maintain him till this revenue begins to come in. His whole stock, therefore, is distinguished into two parts. That part which he expects is to afford him this revenue is called his capital. The other is that which supplies his immediate consumption, and which consists either, first, in that portion of his whole stock which was originally reserved for this purpose; or, secondly, in his revenue, from whatever source derived, as it gradually comes in; or, thirdly, in such things as had been purchased by either of these in former years, and which are not yet entirely consumed, such as a stock of clothes, household furniture, and the like. In one or other, or all of these three articles, consists the stock which men commonly reserve for their own immediate consumption.
There are two different ways in which a capital may be employed so as to yield a revenue or profit to its employer.
First, it maybe employed in raising, manufacturing, or purchasing goods, and selling them again with a profit. The capital employed in this manner yields no revenue or profit to its employer, while it either remains in his possession, or continues in the same shape. The goods of the merchant yield him no revenue or profit till he sells them for money, and the money yields him as little till it is again exchanged for goods. His capital is continually going from him in one shape, and returning to him in another; and it is only by means of such circulation, or successive changes, that it can yield him any profit. Such capitals, therefore, may very properly be called circulating capitals.
Secondly, it may be employed in the improvement of land, in the purchase of useful machines and instruments of trade, or in such like things as yield a revenue or profit without changing masters, or circulating any further. Such capitals, therefore, may very properly be called fixed capitals.
Different occupations require very different proportions between the fixed and circulating capitals employed in them.
The capital of a merchant, for example, is altogether a circulating capital. He has occasion for no machines or instruments of trade, unless his shop or warehouse be considered as such.
Some part of the capital of every master artificer or manufacturer must be fixed in the instruments of his trade. This part, however, is very small in some, and very great in others, A master tailor requires no other instruments of trade but a parcel of needles. Those of the master shoemaker are a little, though but a very little, more expensive. Those of the weaver rise a good deal above those of the shoemaker. The far greater part of the capital of all such master artificers, however, is circulated either in the wages of their workmen, or in the price of their materials, and repaid, with a profit, by the price of the work.
In other works a much greater fixed capital is required. In a great iron-work, for example, the furnace for melting the ore, the forge, the slit-mill, are instruments of trade which cannot be erected without a very great expense. In coal works, and mines of every kind, the machinery necessary, both for drawing out the water, and for other purposes, is frequently still more expensive.
That part of the capital of the farmer which is employed in the instruments of agriculture is a fixed, that which is employed in the wages and maintenance of his labouring servants is a circulating capital. He makes a profit of the one by keeping it in his own possession, and of the other by parting with it. The price or value of his labouring cattle is a fixed capital, in the same manner as that of the instruments of husbandry; their maintenance is a circulating capital, in the same manner as that of the labouring servants. The farmer makes his profit by keeping the labouring cattle, and by parting with their maintenance. Both the price and the maintenance of the cattle which are bought in and fattened, not for labour, but for sale, are a circulating capital. The farmer makes his profit by parting with them. A flock of sheep or a herd of cattle, that, in a breeding country, is brought in neither for labour nor for sale, but in order to make a profit by their wool, by their milk, and by their increase, is a fixed capital. The profit is made by keeping them. Their maintenance is a circulating capital. The profit is made by parting with it; and it comes back with both its own profit and the profit upon the whole price of the cattle, in the price of the wool, the milk, and the increase. The whole value of the seed, too, is properly a fixed capital. Though it goes backwards and forwards between the ground and the granary, it never changes masters, and therefore does not properly circulate. The farmer makes his profit, not by its sale, but by its increase.
The general stock of any country or society is the same with that of all its inhabitants or members; and, therefore, naturally divides itself into the same three portions, each of which has a distinct function or office.
The first is that portion which is reserved for immediate consumption, and of which the characteristic is, that it affords no revenue or profit. It consists in the stock of food, clothes, household furniture, etc. which have been purchased by their proper consumers, but which are not yet entirely consumed. The whole stock of mere dwelling-houses, too, subsisting at anyone time in the country, make a part of this first portion. The stock that is laid out in a house, if it is to be the dwelling-house of the proprietor, ceases from that moment to serve in the function of a capital, or to afford any revenue to its owner. A dwelling-house, as such, contributes nothing to the revenue of its inhabitant; and though it is, no doubt, extremely useful to him, it is as his clothes and household furniture are useful to him, which, however, make a part of his expense, and not of his revenue. If it is to be let to a tenant for rent, as the house itself can produce nothing, the tenant must always pay the rent out of some other revenue, which he derives, either from labour, or stock, or land. Though a house, therefore, may yield a revenue to its proprietor, and thereby serve in the function of a capital to him, it cannot yield any to the public, nor serve in the function of a capital to it, and the revenue of the whole body of the people can never be in the smallest degree increased by it. Clothes and household furniture, in the same manner, sometimes yield a revenue, and thereby serve in the function of a capital to particular persons. In countries where masquerades are common, it is a trade to let out masquerade dresses for a night. Upholsterers frequently let furniture by the month or by the year. Undertakers let the furniture of funerals by the day and by the week. Many people let furnished houses, and get a rent, not only for the use of the house, but for that of the furniture. The revenue, however, which is derived from such things, must always be ultimately drawn from some other source of revenue. Of all parts of the stock, either of an individual or of a society, reserved for immediate consumption, what is laid out in houses is most slowly consumed. A stock of clothes may last several years; a stock of furniture half a century or a century; but a stock of houses, well built and properly taken care of, may last many centuries. Though the period of their total consumption, however, is more distant, they are still as really a stock reserved for immediate consumption as either clothes or household furniture.
