The Pathfinder, or The Inland Sea is a historical novel by James Fenimore Cooper, first published in 1840. It is the fourth novel Cooper wrote featuring Natty Bumppo, his fictitious frontier hero, and the third chronological episode of the Leatherstocking Tales. The inland sea of the title is Lake Ontario. Plot: The Pathfinder shows Natty at his old trick of guiding tender damsels through the dangerous woods, and the siege at the blockhouse and the storm on Lake Ontario are considerably like other of Cooper's sieges and storms. Natty, in this novel commonly called La Longue Carabine, keeps in a hardy middle age his simple and honest nature, which is severely tested by his love for a young girl. She is a conventional heroine of romance. A certain soft amiability about her turns for a time all the thoughts of the scout to the world of domestic affections. More talkative than ever before, he reveals new mental and moral traits. With the same touch of realism which had kept Uncas and Cora apart in The Last of the Mohicans, Cooper separates these lovers, and sends Natty's romantic interest to the arms of a younger suitor, restoring the hero to his home in the wilderness.... James Fenimore Cooper (September 15, 1789 - September 15, 1851) was a prolific and popular American writer of the early 19th century. His historical romances of frontier and Indian life in the early American days created a unique form of American literature. He lived most of his life in Cooperstown, New York, which was founded by his father William on property that he owned. Cooper was a lifelong member of the Episcopal Church and, in his later years, contributed generously to it.He attended Yale University for three years, where he was a member of the Linonian Society, but was expelled for misbehavior. Before embarking on his career as a writer, he served in the U.S. Navy as a Midshipman, which greatly influenced many of his novels and other writings. The novel that launched his career was The Spy, a tale about counterespionage set during the Revolutionary War and published in 1821. He also wrote numerous sea stories, and his best-known works are five historical novels of the frontier period known as the Leatherstocking Tales. Among naval historians, Cooper's works on the early U.S. Navy have been well received, but they were sometimes criticized by his contemporaries. Among his most famous works is the Romantic novel The Last of the Mohicans, often regarded as his masterpiece
