Harvey Birch, the hero of _The Spy_, is a portrait from the life of a revolutionary patriot who appears in the book as a peddler with a keen eye to trade as well as to the movements of the enemy. One of the best known incidents in the book is that in which Harvey, by a clever stratagem, assists Capt. Wharton to escape. James Fenimore Cooper (1789-1851) was born at Burlington, N.J., but was reared in the wild country around Otsego Lake, in central N.Y., on the yet unsettled estates of his father. It was here he learned the backwoods lore, which in combination with his romantic genius, made him one of the most popular of authors. Among the literary residents of Tarrytown have been Mrs. E. D. E. N. Southworth, well known to a previous generation for her romantic novels, John Kendrick Bangs, the humorist, and Hamilton Wright Mabie, editor and essayist. Carl Schurz (1829-1906) is buried here in the Sleepy Hollow churchyard. Tarrytown is the trading center of a prosperous agricultural region; it also has about 100 manufacturing establishments with a large output. Just north of Kingsland Point (seen at the left, on the east bank of the river), the seat of William Rockefeller comes into view on the right, and behind it, among the hills, is the estate of his brother, John D. Rockefeller. John D. Rockefeller was born in 1839 at Richford, Tioga Co., N.Y., but his family moved to Cleveland while he was still a boy, and his career was begun there. In 1858 he went into the produce commission business, and 4 years later his company invested in an oil refinery. Mr. Rockefeller kept constantly adding to his influence and possessions in this field until by 1872 the Standard Oil Co. was organized with him as president, and a practical control of oil production in America was secured. This was the first great American "trust." Mr. Rockefeller himself retired from active business in 1895. While his wealth is enormous, his benefactions have been on an equal scale, comprising gifts to the Baptist Church, the founding of educational institutions and the supporting of those already existent. Scientific research in medical fields has been a particular object of his generosity.
