BARTRAM’S GARDEN, 28 acres, open free to the public, one quarter mile south on Fifty-fourth Street, first botanical garden of international importance in United States; ground purchased by John Bartram, in 1728; from here he traveled long distances to Florida, the Adirondacks, everywhere collecting rare plants that he brought home in his saddlebags; he wrote down the results of his explorations, and sent to Europe botanical specimens of great interest, also painted sheets of illustrations, sending one set to the South Kensington Museum, London, which are still there in perfect condition; Linnæus proclaimed him the greatest natural botanist in the world, and sent him books and apparatus; his quaint old stone house is still standing, built by himself in 1731; his son, William Bartram, botanist and ornithologist, published the most complete list of American birds, previous to Alexander Wilson, whom he greatly assisted. Wilson lived at the corner of Fifty-first Street and Woodland Avenue, in a log house with an immense stone chimney. Near Bartram’s Garden, on the Schuylkill River bank, at the western end of Gray’s Ferry Bridge, is site of Gray’s Garden, pleasure resort, time of Washington, reached from Philadelphia by a floating bridge, replaced by wooden telescope drawbridge built in 1808, by the P., W. & B. R. R.; stone monument, still standing, covered with most interesting and historically valuable inscriptions, marks opening of the first railroad to the South.
