study of the law is useful in a variety of points of view. It qualifies a man to be useful to himself, to his neighbors, and to the public. It is the most certain stepping-stone to preferment in the political line. In political economy, I think Smith's Wealth of Nations the best book extant; in the science of government, Montesquieu's Spirit of Laws is generally recommended. It contains, indeed, a great number of political truths; but also an equal number of heresies: so that the reader must be constantly on his guard. There has been lately published a letter of Helvetius, who was the intimate friend of Montesquieu, and whom he consulted before the publication of his book. Helvetius advised him not to publish it; and in this letter to a friend he gives us a solution for the mixture of truth and error found in this book. He says Montesquieu was a man of immense reading; that he had commonplaced all his reading, and that his object was to throw the whole contents of his commonplace book into systematical order, and to show his ingenuity by reconciling the contradictory facts it presents. Locke's little book on Government, is perfect as far as it goes. Descending from theory to practice there is no better book than the Federalist. Burgh's Political Disquisitions are good also, especially after reading De Lome. Several of Hume's Political Essays are good. There are some excellent books of theory written by Turgot and the economists of France. For parliamentary knowledge, the Lex Parliamentaria is the best book. On my return to Virginia in the fall, I cannot help hoping some practicable plan may be devised for your settling in Albemarle, should your inclination lead you to it. Nothing could contribute so much to my happiness were it at the same time consistent with yours. You might get into the Assembly for that county as soon as you should please.
