In all new colonies, the great quantity of waste land, which can for many years be applied to no other purpose but the feeding of cattle, soon renders them extremely abundant; and in every thing great cheapness is the necessary consequence of great abundance. Though all the cattle of the European colonies in America were originally carried from Europe, they soon multiplied so much there, and became of so little value, that even horses were allowed to run wild in the woods, without any owner thinking it worth while to claim them. It must be a long time after the first establishment of such colonies, before it can become profitable to feed cattle upon the produce of cultivated land. The same causes, therefore, the want of manure, and the disproportion between the stock employed in cultivation and the land which it is destined to cultivate, are likely to introduce there a system of husbandry, not unlike that which still continues to take place in so many parts of Scotland. Mr Kalm, the Swedish traveller, when he gives an account of the husbandry of some of the English colonies in North America, as he found it in 1749, observes, accordingly, that he can with difficulty discover there the character of the English nation, so well skilled in all the different branches of agriculture. They make scarce any manure for their corn fields, he says; but when one piece of ground has been exhausted by continual cropping, they clear and cultivate another piece of fresh land; and when that is exhausted, proceed to a third. Their cattle are allowed to wander through the woods and other uncultivated grounds, where they are half-starved; having long ago extirpated almost all the annual grasses, by cropping them too early in the spring, before they had time to form their flowers, or to shed their seeds.[24] The annual grasses were, it seems, the best natural grasses in that part of North America; and when the Europeans first settled there, they used to grow very thick, and to rise three or four feet high. A piece of ground which, when he wrote, could not maintain one cow, would in former times, he was assured, have maintained four, each of which would have given four times the quantity of milk which that one was capable of giving. The poorness of the pasture had, in his opinion, occasioned the degradation of their cattle, which degenerated sensibly from one generation to another. They were probably not unlike that stunted breed which was common all over Scotland thirty or forty years ago, and which is now so much mended through the greater part of the low country, not so much by a change of the breed, though that expedient has been employed in some places, as by a more plentiful method of feeding them.
