Cooper passed through all these stirring scenes, known to those around him only as a boy before the mast, but in reality the clever student and observer of men and events. His work was hard and dangerous; he was never admitted to the cabin, though an equal, socially, to the officers of the ship; in storm or wind or other danger his place was on the deck among the rough sailors, who were his only companions during the voyage. But this training developed the good material that was in him, and when, in 1808, he received his commission as midshipman, he entered the service better equipped for his duties perhaps than many a graduate of Annapolis to-day.
Cooper remained in the navy three years and a half, seeing no active service. He finally resigned his commission, and passed several succeeding years of his life partly in Westchester County, New York, and partly in Cooperstown, and having no ambition beyond living the quiet life of a country gentleman.
It was not until 1820, when he was in his thirty-first year, that he produced his first book or novel of English life, which showed no talent, and which even his most ardent admirers in after-years could not read through. It was not until the next year, 1821, that a novel appeared from the hand of Cooper which foreshadowed the greatness of his fame, and struck a new note in American literature. American society was at that time alive with the stirring memories of the Revolution. Men and women were still active who could recall the victories of Bunker Hill and Trenton, and who had shared in the disasters of Monmouth and Long Island. It is natural that in choosing a subject for fiction he should turn to the recent struggle for his inspiration, and American literature owes a large debt to him who thus threw into literary form the spirit of those thrilling times.
His first important novel, The Spy, was founded upon a story which Cooper had heard many years before, and which had made a profound impression upon him. It was the story of a veritable spy, who had been in the service of one of the Revolutionary leaders, and whose daring and heroic adventures were related to Cooper by the man who had employed him.
Cooper took this old spy for his hero, kept the scene in Westchester, where the man had really performed his wonderful feats, and from these facts wove the most thrilling and vital piece of fiction that had appeared in America.
The novel appeared in December, 1821, and in a few months it was apparent that a new star had risen in the literary skies. The book made Cooper famous both in America and Europe. It was published in England by the same publisher who had brought out Irving's Sketch-Book, and it met with a success that spoke highly for its merit, since the story was one telling of English defeat and American triumph. It was put into French by the translator of the Waverley novels, and before long versions appeared in every tongue in Europe. It was regarded not merely as a tale of adventure in a new department of story-telling, but it was generally conceded to be a fine piece of fiction in itself, and its hero, Harvey Birch, won, and has kept for himself, a place hardly second to any creation of literature.
Cooper had now found his sphere, and his best work henceforth was that in which he delineated the features of American history during the struggle for independence. His greatest contributions to literature are found in the short series of novels called "The Leatherstocking Tales," and in his novels of the sea. "The Leatherstocking Tales" consist of five stories, in which the same hero figures from first to last. The series began with the publication of Cooper's second novel, The Pioneers, but the story of the hero really begins in the fascinating pages of The Deerslayer, where he is represented in the first stage of his career.
The series grew much as Tennyson's Idylls of the King grew, the same man being introduced in different parts of his career, though each separate book did not follow in exact order from the author's hand. The success of The Pioneers was remarkable. Thirty-five hundred copies were sold before noon on the day of publication, and although, perhaps, the least powerful of the "Tales," it was read with the same interest that had been given to The Spy.
In the new novel Leatherstocking was first introduced as the philosopher of nature, ignorant of books, but wise in the lore that is taught by the voices of Nature. It is a story of the primitive life of the frontiersmen of that day, and their occupations, interests, and ambitions form the background to the picture of the hero, Leatherstocking, who embodies the author's idea of chivalrous manhood, and whose creation is one of the noblest achievements of fiction.
The scene of The Pioneers was laid in the vicinity of Cooper's boyhood home, and all the exquisite pictures wrought into the setting are vivid and lifelike illustrations of the little frontier village, where man received his sustenance first hand from Nature, and where all his surroundings partook almost of the simplicity of the first ages of the world. It was an appropriate theatre for the actions of that rustic philosopher Leatherstocking, and there is a vein of tender reminiscence through the book that must always give it a charm apart from the rest, though in itself it is the least perfect story of the series.
