complicated instrument of the multiplication of wealth, or unveiling the prodigies of the most powerful of its resources. On the other hand, he has often introduced long digressions, which interrupt the thread of his discussion, and, in many cases, completely destroy the connection of its several parts. Of this description is the digression On the variations in the value of the precious metals during the four last centuries, with a critical examination of the opinions that their value is decreasing--book 1, chap. xi. Upon banks of circulation and paper money--book 2, chap. ii. Upon banks of deposit, and particularly that of Amsterdam--book 4, chap. iii. Upon the advantage of seignorage in the coining of money--book 4, chap. vi. Upon the commerce of grain, and the laws regarding this trade--book 4, chap. v. These different treatises, although they are unquestionably the best that have ever been written on the subjects to which they relate, are, however, so introduced, as to distract the reader's attention--to make him lose sight of the principal object of the work--and to lessen the general effect of it as a whole. To remedy, as far as I am able, these inconveniencies, and to facilitate to beginners the study of the doctrine of Smith, I have thought proper to point out the order which appears to me most agreeable to the natural progress of ideas, and, on this account, best calculated for the purpose of instruction. I would begin by remarking, that the whole doctrine of Smith, upon the origin, multiplication, and distribution of wealth, is contained in his two first books; and that the three others may be read separately, as so many detached treatises, which, no doubt, confirm and develope his opinions, but do not by any means add to them. The third book is an historical and political discussion on the progress which wealth would make in a country where labour and industry were left free; and upon the different causes which have tended, in all the countries of Europe, to reverse this progress. In the fourth book, the author has endeavoured to combat the various systems of political economy which were popular previous to his time; and, in a particular manner, that which is denominated the mercantile system, which has exercised so strong an influence over the financial regulations of the European governments, and particularly over those of England. In the fifth and last book, he considers the expenses of government; the most equitable and convenient modes of providing for these expenses; and lastly, public debts, and the influence they have over national prosperity. The three last books may be read and studied in the same order and arrangement in which they were written, without any difficulty, by one who is completely master of the general doctrine contained in the two first. I regard, then, the two first books, as a complete work, which I would divide into three parts.
