Picturesque suburbs adorned by magnificent villas environ the built-up parts of Hartford, making a splendid semi-rural residential section, where arching elms embower the lawn-bordered avenues, many localities being adorned by superb hedges. There is a fine artistic and historical collection in the Wadsworth Atheneum, where, among other precious relics, are kept General Putnam's sword and the Indian King Philip's club. Mrs. Harriet Beecher Stowe, and Mrs. Sigourney, the poetess, were long residents of Hartford. The citizen whom it holds in steadfast memory, however, is Colonel Samuel Colt, who invented the revolving pistol. He was born in Hartford, and his remains rest under a fine monument in Cedar Hill Cemetery. His widow built as his memorial a beautiful little brownstone chapel, the Church of the Good Shepherd, which is not far away from the huge works of the Colt Arms Company, the chief industrial establishment of the city. Colt, when a boy, ran away from home and went to sea, and is said to have there conceived the idea of his great invention. He sought vainly during several years to establish a factory to make it, but did not prosper until 1852, when he started in Hartford; and with the great demand for small-arms then stimulated by the opening of the California gold mines and the exploration of the Western plains, afterwards expanded by the Civil War, his factory grew enormously. The heraldic "colt rampant" adopted by the inventor is stamped on all the arms and reproduced in all the decorations of these vast works. Among other large factories is also the Pope bicycle works. A short distance west of Hartford is New Britain, where there are twenty thousand people engaged in making hardware, locks and jewelry, its noted resident having been Elihu Burritt, the "Learned Blacksmith," who was born there in 1810 and died in 1879.
