To get available room and facilitate business, the city has gathered the terminals of all the railways into two enormous stations on the northern and southern sides of the town, and for nearly a half century it has been filling-in the fens and lowlands to the westward, so that now this reclaimed West End is the fashionable section, containing the finest churches, hotels, and residences. Through this splendid district extends for over a mile the grand Commonwealth Avenue, two hundred and forty feet wide, its centre being a tree-embowered park adorned by statues of Alexander Hamilton, John Glover, William Lloyd Garrison, and Leif Ericson, and having on either side a magnificent boulevard. The bordering residences are fronted by delicious gardens, and at regular intervals fine streets cross at right angles, their names arranged alphabetically, in proceeding westward, with the well-known English titles, Arlington, Berkeley, Clarendon, Dartmouth, Exeter, Fairfield, Gloucester, Hereford, etc. Parallel to the Avenue are also laid out Boylston, Marlborough, Newbury and Beacon Streets through this favorite residential section. Proceeding out Boylston Street are passed the stately buildings of the Museum of Natural History, and the Massachusetts Institute of Technology, with twelve hundred students, the leading institution of its kind in America. Beyond, at the intersection of Dartmouth Street, is Copley Square, displaying around it the finest architectural group in the city, five magnificent buildings, three of them churches. Trinity Episcopal Church, built on the northern side, in free Romanesque, is formed as a Latin cross, with a massive central tower, two hundred and ten feet high. It has elaborate interior decoration and fine windows. The Public Library, on the southern side, is in Roman Renaissance, two hundred and twenty-eight by two hundred and twenty-five feet, and sixty-eight feet high, erected at a cost of nearly $2,400,000. It contains eight hundred thousand volumes, and the interior is excellently adapted to its uses, being tastefully adorned. The Second Unitarian Church, on the northern side of the square, built in 1874, was the church of the three Mathers, and of Ralph Waldo Emerson. The Museum of Fine Arts, on the eastern side of the square, is constructed of red brick and terra-cotta, and contains extensive collections. The fifth building fronting the square is the "New Old South Church," in Italian Gothic, with a tower rising two hundred and forty-eight feet.
