literary vein, and he had gained confidence in himself as a writer. Following this pronounced success in authorship, Cooper set to work on a third book and continued for the remainder of his life to devote most of his time to writing. Altogether he wrote over thirty novels and as many more works of a miscellaneous character. But much of this writing has no interest for us at the present time, especially that which was occasioned by the many controversies in which the rather belligerent Cooper involved himself. His work of permanent value after _The Spy_ falls into two groups, the tales of wilderness life and the sea tales. Both these groups grew directly out of his experiences in early life. Cooper was born on September 15, 1789, in Burlington, New Jersey, but while still very young he was taken to Cooperstown, on the shores of Otsego Lake, in central New York. His father owned many thousand acres of primeval forest about this village, and so through the years of a free boyhood the young Cooper came to love the wilderness and to know the characters of border life. When the village school was no longer adequate, he went to study privately in Albany and later entered Yale College. But he was not interested in the study of books. When, as a junior, he was expelled from college, he turned to a career in the navy. Accordingly in the fall of 1806 he sailed on a merchant ship, the _Sterling_, and for the next eleven months saw hard service before the mast. Soon after this apprenticeship he received a commission as a midshipman in the United States navy. Although it was a time of peace, and he saw no actual fighting, he gained considerable knowledge from his service on Lake Ontario and Lake Champlain that he put to good use later. Shortly before his resignation in May, 1811, he had married, and for several years thereafter he lived along in a pleasant, leisurely fashion, part of the time in Cooperstown and part of the time in Westchester County, until almost accidentally he broke into the writing of his first novel. Aside from the publication of his books, Cooper’s later life was essentially uneventful. He died at Cooperstown, on September 14, 1851. The connection of Cooper’s best writing with the life he knew at first hand is thus perfectly plain. In his novels dealing with the wilderness, popularly known as the Leatherstocking Tales, he drew directly on his knowledge of the backwoods and backwoodsmen as he gained it about Cooperstown. In _The Pioneers_ (1823) he dealt with the scenes of his boyhood, scenes which lay very close to his heart; and in the other volumes of this series, _The Last of the Mohicans_ (1826), _The Prairie_ (1827), _The Pathfinder_ (1840), and _The Deerslayer_ (1841), he continued to write of the trappers and frontiersmen and outpost garrisons and Indians who made up the forest life he knew so well. Similarly, in the sea tales, which began with ‘The Pilot’(1823) and included ‘The Red Rover’(1828), ‘The Two Admirals’ (1842) and ‘The Wing-and-Wing’(1842), he made full use of his experiences before the mast and in the navy. The nautical accuracy of these tales of the sea could scarcely have been attained by a “landlubber”. It has much practical significance, then, that Cooper chose material which he knew intimately and which gripped his own interest. His success came like Thackeray’s and Stevenson’s and Mark Twain’s—without his having to reach to the other side of the world after his material. In considering Cooper’s work as a...
