Rh clearness, are really on this subject much more confused than even those of Adam Smith, and more decidedly infected with the often refuted notion that the competition of capital lowers general prices; the subject of Money apparently not having been included among the parts of Political Economy which this acute and vigorous writer had carefully studied.

Mr. Wakefield's explanation of the fall of profits is briefly this. Production is limited not solely by the quantity of capital and of labour, but also by the extent of the "field of employment." The field of employment for capital is twofold; the land of the country, and the capacity of foreign markets to take its manufactured commodities. On a limited extent of land, only a limited quantity of capital can find employment at a profit As the quantity of capital approaches this limit, profit falls; when the limit is attained, profit is annihilated; and can only be restored through an extension of the field of employment, either by the acquisition of fertile land, or by opening new markets in foreign countries, from which food and materials can be purchased with the products of domestic capital. These propositions are, in my opinion, substantially true; and, even to the phraseology in which they are expressed, considered as adapted to popular and practical rather than scientific uses, I have nothing to object. The error which seems to me imputable to Mr. Wakefield is that of supposing his doctrines to be in contradiction to the principles of the best school of preceding political economists, instead of being, as they really are, corollaries from those principles; though corollaries which, perhaps, would not always have been admitted by those political economists themselves. The most scientific treatment of the subject which I have met with, is in an essay on the effects of Machinery, published in the Westminster Review for January 1820, by Mr. William Ellis; which was doubtless unknown to Mr. Wake-
