But the general scope of an argument may be just, though clumsily stated and fallaciously supported. We are, however, at no loss for experiments on the largest scale whereby to test the theory here noticed. We have English agriculture, subjected to a limited law of entail, contrasted on the one hand with Scottish agriculture, under a law of perpetual entail, and on the other with that of France and its compulsory gavelkind. Mr M'Culloch has taken an elaborate view of the question in its relation to the tillage of the soil in these three countries respectively, more especially in France. We find, from the result of his investigation, that,-- "The average produce per acre of the crops of wheat in England and Wales in good years, has been carefully estimated at thirty-two bushels an acre, and it is certainly not under thirty bushels. But in France the produce of wheat, even in the richest and best cultivated departments, is little more, according to the official returns and the best private authorities, than twenty bushels an acre; and at an average of the entire kingdom, it hardly amounts in a good year to fourteen bushels. This result is completely decisive. It shows that one acre of land in England yields, from its being better farmed, considerably more wheat than two acres in France: and if we took barley or oats, turnips, beef, or wool for a standard, the difference in our favour would be seen to be still greater.... If labour were taken for a standard instead of land, the result would be still more in our favour. One man and one horse in England produce more corn and other agricultural produce than three men and three horses in France. Labour in the latter is misapplied and wasted."--P. 117. Again:-- "While two husbandmen in France furnish a surplus of food above their own consumption adequate for _one_ individual, the same number of English husbandmen furnish a surplus for no fewer than _four_ individuals; showing, that, as measured by its capacity of providing for the other classes of the population, English is to French agriculture as four to one."--P. 121. So much for the comparison of French and English agriculture. Let us now turn to Scotland:--
