THREE:The miscellaneous literature of this reign was immense, consisting of travels, biographies, essays on all subjects, and treatises in every department of science and letters. Prominent amongst these are the "Letters of Junius," who, in the early part of the reign, kept the leading statesmen, judges, and the king himself, in terror by the relentlessness of his scarifying criticisms. These letters, which are the perfection of political writing, have been ascribed to many authors, but most generally to Sir Philip Francis; though it is hard to speak on the subject with certainty. The writings of Dr. Johnson furnish many items to this department. His "Dictionary of the English Language" (1755) was a gigantic labour; his "Lives of the Poets," his "Tour to the Western Isles," would of themselves have made a reputation, had he never written his poetry, his periodical essays, or edited Shakespeare. Burke, too, besides his Speeches, added largely to general literature. He wrote his "Inquiry into the Origin of the Sublime and Beautiful;" assisted in the composition of the Annual Register for several years; and, in 1790, published his most famous work, "Reflections on the French Revolution." Besides these he wrote political letters and essays. Lady Mary Wortley Montagu produced her celebrated Letters about the middle of the century, and many other women were popular writers at this period: Sophia and Harriett Lee, Anna Maria Williams, Mrs. Lennox, Mrs. Catherine Talbot, Elizabeth Carter, the translator of Epictetus, Mrs. Montagu, an essayist on Shakespeare, Mrs. Chapone, author of "Letters on the Improvement of the Mind," Mrs. Barbauld, and Mrs. Charlotte Smith. In theology, metaphysics, and mental philosophy, the earlier portion of the reign was rich. In rapid succession appeared Reid's "Inquiry into the Human Mind," Campbell's "Answer to Hume on Miracles," Beattie's "Essay on Truth," Wallace's "Essay on the Numbers of Mankind," and Stuart's "Enquiry into the Principles of Political Economy." But nine years after Stuart's work appeared another on the same subject, which raised that department of inquiry into one of the most prominent and influential sciences of the age. This was the famous treatise "On the Nature and Causes of the Wealth of Nations," by Adam Smith (1776), which produced a real revolution in the doctrines of the production and accumulation of wealth. In teaching the advantages of free trade and the division of labour it has rendered incalculable services to mankind.Those princes that did bring men into the field, such as the Hessians, Brunswickers, etc.the Menschen-Ver?ufer, or man-sellers, as they were styled by their own peoplewere rapacious beyond example. During the American war we had employed these Hessians, Brunswickers, and the like, at a cost that excited general indignation. Besides paying seven pounds ten shillings and a penny for every man, the Duke of Brunswick, who furnished only four thousand and eighty-four men, had had an annual subsidy of fifteen thousand five hundred and nineteen pounds. The Landgrave of Hesse-Cassel, who furnished twelve thousand men, had ten thousand two hundred and eighty-one pounds a year.
