I say nothing of his "Theory of Moral Sentiments," which constitutes an important contribution to the science of ethics, but come at once to his great work of political economy, entitled "Inquiry into the Nature and Sources of the Wealth of Nations," which first appeared in 1776. Its publication marks an epoch which is described by Mr. Buckle when he says: "Adam Smith contributed more, by the publication of this single work, toward the happiness of man, than has been effected by the united abilities of all the statesmen and legislators of whom history has preserved an authentic account." The work is full of prophetic knowledge, and especially with regard to the British colonies. Writing while the debate with the mother country was still pending, Adam Smith urged that they should be admitted to Parliamentary representation in proportion to taxation, so that their representation would enlarge with their growing resources; and here he predicts nothing less than the transfer of empire. "The distance of America from the seat of government, the natives of that country might flatter themselves, with some appearance of reason too, would not be of very long continuance. Such has hitherto been the rapid progress of that country in wealth, population, and improvement, that, in the course of little more than a century, perhaps, the produce of America might exceed that of British taxation. _The seat of the empire would then naturally remove itself to that part of the empire which contributed most to the general defence and support of the whole._"[38] In these tranquil words of assured science this great author carries the seat of government across the Atlantic. GOVERNOR POWNALL.--1777, 1780, 1785. Among the best friends of our country abroad during the trials of the Revolution was Thomas Pownall, called by one biographer "a learned antiquary and politician," and by another "an English statesman and author." Latterly he has so far dropped out of sight, that there are few who recognize in him either of these characters. He was born, 1722, and died at Bath, 1805. During this long period he held several offices. As early as 1745 he became secretary to the Commission for Trade and Plantations. In 1753 he crossed the ocean. In 1755, as Commissioner for Massachusetts Bay, he negotiated with New York, New Jersey, and Pennsylvania, in union with New England, the confederated expedition against Crown Point. He was afterwards Governor of Massachusetts Bay, New Jersey, and South Carolina, successively. Returning to England, he was, in 1761, Comptroller-General of the army in Germany, with the military rank of Colonel. He sat in three successive Parliaments until 1780, when he passed into private life. Hildreth gives a glimpse at his personal character, when, admitting his frank manners and liberal politics, he describes his "habits as rather freer than suited the New England standard."[39]
