 this second sort of rude produce, cattle is, perhaps, that of which the price, in the progress of improvement, first rises 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 labor and be too expensive. If the price of the cattle, therefore, is not sufficient to pay for the produce of improved and cultivated 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 labor, 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
