Of the capability of the foreigner to supply us with any given amount of grain, we think no reasonable man can doubt. There is a breadth of soil open sufficient to supply more than twenty times the most exorbitant demand. It is his power to undersell us, and the extent of that power, which have been questioned; and on the solution of that question depends the utility of high farming, in this country, on a grand and comprehensive scale. We shall show that, at present prices, high farming is so far from remunerative, that those who practise it are actually incurring an immense loss; and that, unless rents come down to zero, or at least to a point which would utterly ruin the landlords, high farming cannot be proceeded with. We have shown that, within the last five years, we have been supplied, and that regularly, from abroad, when wheat was at 46s. per quarter, and a duty of 20s. existed; and, at such rates, it is quite evident that all attempt at competition would be hopeless. Wheat could not be grown remuneratively at 26s. or 27s. in England before a single shilling of the national debt was incurred; and no man is mad enough to insist upon its possibility now. When, therefore, the Free-traders tell us that the present is a mere temporary depreciation, we ask them--and we demand a distinct reply--for an explanation of the imports in 1845. How was it that, for a long period, foreign corn came in plentifully, paying the duty of 20s., when our home averages were at 46s. and 47s.? Can they assign any special reason for it? If not, the conclusion is plain, that the foreign growers can and will undersell us down to that point, if we possibly could compete with them so far, and all the while add to their profit, while they also abstract from our revenue.
