Second sort. –The second sort of rude produce, of which the price rises in the progress of improvement, is that which human industry can multiply in proportion to the demand. It consists in those useful plants and animals, which, in uncultivated countries, nature produces with such profuse abundance, that they are of little or no value, and which, as cultivation advances, are therefore forced to give place to some more profitable produce. During a long period in the progress of improvement, the quantity of these is continually diminishing, while, at the same time, the demand for them is continually increasing. Their real value, therefore, the real quantity of labour which they will purchase or command, gradually rises, till at last it gets so high as to render them as profitable a produce as any thing else which human industry can raise upon the most fertile and best cultivated land. When it has got so high, it cannot well go higher. If it did, more land and more industry would soon be employed to increase their quantity.
When the price of cattle, for example, rises so high, that it is as profitable to cultivate land in order to raise food for them as in order to raise food for man, it cannot well go higher. If it did, more corn land would soon be turned into pasture. The extension of tillage, by diminishing the quantity of wild pasture, diminishes the quantity of butcher’s meat, which the country naturally produces without labour or cultivation; and, by increasing the number of those who have either corn, or, what comes to the same thing, the price of corn, to give in exchange for it, increases the demand. The price of butcher’s meat, therefore, and, consequently, of cattle, must gradually rise, till it gets so high, that it becomes as profitable to employ the most fertile and best cultivated lands in raising food for them as in raising corn. But it must always be late in the progress of improvement before tillage can be so far extended as to raise the price of cattle to this height; and, till it has got to this height, if the country is advancing at all, their price must be continually rising. There are, perhaps, some parts of Europe in which the price of cattle has not yet got to this height. It had not got to this height in any part of Scotland before the Union. Had the Scotch cattle been always confined to the market of Scotland, in a country in which the quantity of land, which can be applied to no other purpose but the feeding of cattle, is so great in proportion to what can be applied to other purposes, it is scarce possible, perhaps, that their price could ever have risen so high as to render it profitable to cultivate land for the sake of feeding them. In England, the price of cattle, it has already been observed, seems, in the neighbourhood of London, to have got to this height about the beginning of the last century; but it was much later, probably, before it got through the greater part of the remoter counties, in some of which, perhaps, it may scarce yet have got to it. Of all the different substances, however, which compose this second sort of rude produce, cattle is, perhaps, that of which the price, in the progress of improvement, rises first to this height.
Till the price of cattle, indeed, has got to this height, it seems scarce possible that the greater part, even of those lands which are capable of the highest cultivation, can be completely cultivated. In all farms too distant from any town to carry manure from it, that is, in the far greater part of those of every extensive country, the quantity of well cultivated land must be in proportion to the quantity of manure which the farm itself produces; and this, again, must be in proportion to the stock of cattle which are maintained upon it. The land is manured, either by pasturing the cattle upon it, or by feeding them in the stable, and from thence carrying out their dung to it. But unless the price of the cattle be sufficient to pay both the rent and profit of cultivated land, the farmer cannot afford to pasture them upon it; and he can still less afford to feed them in the stable. It is with the produce of improved and cultivated land only that cattle can be fed in the stable; because, to collect the scanty and scattered produce of waste and unimproved lands, would require too much labour, and be too expensive. It the price of the cattle, therefore, is not sufficient to pay for the produce of improved and cuitivated land, when they are allowed to pasture it, that price will be still less sufficient to pay for that produce, when it must be collected with a good deal of additional labour, and brought into the stable to them. In these circumstances, therefore, no more cattle can with profit be fed in the stable than what are necessary for tillage. But these can never afford manure enough for keeping constantly in good condition all the lands which they are capable of cultivating. What they afford, being insufficient for the whole farm, will naturally be reserved for the lands to which it can be most advantageously or conveniently applied; the most fertile, or those, perhaps, in the neighbourhood of the farm-yard. These, therefore, will be kept constantly in good condition, and fit for tillage. The rest will, the greater part of them, be allowed to lie waste, producing scarce any thing but some miserable pasture, just sufficient to keep alive a few straggling, half-starved cattle; the farm, though much overstocked in proportion to what would be necessary for its complete cultivation, being very frequently overstocked in proportion to its actual produce. A portion of this waste land, however, after having been pastured in this wretched manner for six or seven years together, may be ploughed up, when it will yield, perhaps, a poor crop or two of bad oats, or of some other coarse grain; and then, being entirely exhausted, it must be rested and pastured again as before, and another portion ploughed up, to be in the same manner exhausted and rested again in its turn. Such, accordingly, was the general system of management all over the low country of Scotland before the Union. The lands which were kept constantly well manured and in good condition seldom exceeded a third or fourth part of the whole farm, and sometimes did not amount to a fifth or a sixth part of it. The rest were never manured, but a certain portion of them was in its turn, notwithstanding, regularly cultivated and exhausted. Under this system of management, it is evident, even that part of the lands of Scotland which is capable of good cultivation, could produce but little in comparison of what it may be capable of producing. But how disadvantageous soever this system may appear, yet, before the Union, the low price of cattle seems to have rendered it almost unavoidable. If, notwithstanding a great rise in the price, it still continues to prevail through a considerable part of the country, it is owing in many places, no doubt, to ignorance and attachment to old customs, but, in most places, to the unavoidable obstructions which the natural course of things opposes to the immediate or speedy establishment of a better system: first, to the poverty of the tenants, to their not having yet had time to acquire a stock of cattle sufficient to cultivate their lands more completely, the same rise of price, which would render it advantageous for them to maintain a greater stock, rendering it more difficult for them to acquire it; and, secondly, to their not having yet had time to put their lands in condition to maintain this greater stock properly, supposing they were capable of acquiring it. The increase of stock and the improvement of land are two events which must go hand in hand, and of which the one can nowhere much outrun the other. Without some increase of stock, there can be scarce any improvement of land, but there can be no considerable increase of stock, but in consequence of a considerable improvement of land; because otherwise the land could not maintain it. These natural obstructions to the establishment of a better system, cannot be removed but by a long course of frugality and industry; and half a century or a century more, perhaps, must pass away before the old system, which is wearing out gradually, can be completely abolished through all the different parts of the country. Of all the commercial advantages, however, which Scotland has derived from the Union with England, this rise in the price of cattle is, perhaps, the greatest. It has not only raised the value of all highland estates, but it has, perhaps, been the principal cause of the improvement of the low country.
