At present Cleveland extends for over 14 miles along Lake Erie and covers more than 50 square miles. The larger part of the city lies to the east of the Cuyahoga River. The valley of this river is filled with car tracks, lumber yards, car shops, coal sheds, ore docks, and shipyards. Being in the valley, these are partially hidden from the city. Huge viaducts span the valley and unite the east and west sides of Cleveland. [Illustration: THE HEART OF THE BUSINESS QUARTER] The heart of the business quarter and the center of the street railway lines is Monumental Square, which lies about a mile from the lake shore. From this square radiate the streets in a fan shape, at every angle from northeast to west. Euclid Avenue is Cleveland's most famous street, having for years enjoyed the reputation of being one of the country's finest avenues. The lower end is taken up with business, but farther out are many splendid residences surrounded by extensive and beautifully kept lawns. Cleveland is called the Forest City, and it is to the old trees which grace its parks and line both sides of Euclid Avenue that it owes its name. Another important business street is Superior Avenue, which runs through the main business portion of the city. [Illustration: MONUMENTAL SQUARE] [Illustration: LOOKING UP EUCLID AVENUE] Though Cleveland is a beautiful city, its importance really lies in the fact of its occupying just the position that it does. Being on Lake Erie puts it in touch with the copper fields of Michigan, the iron mines of Minnesota and Michigan, and the huge forests along the Great Lakes. Through railroad connections it is also in touch with the coal, oil, and iron supplies of western Pennsylvania and Ohio. Thus, lying in the center of eastern and western commerce, Cleveland has become a great manufacturing center, and the Cleveland district is the largest ore market in the world. Lake vessels bring the ore to Cleveland's enormous docks, where huge machines quickly transfer it to cars waiting to carry it to Pittsburgh and other cities. [Illustration: ORE DOCKS] [Illustration: WHEELING & LAKE ERIE BRIDGE] Cleveland, also, has several blast furnaces and immense factories of iron and steel supplies. It holds first rank in America for the making of wire and nails. More ships are built in the Cleveland district than anywhere else in the world except in the shipyards on the Clyde River in Scotland. Then, too, Cleveland makes steel bridges and buildings, automobiles, and gas ranges. Quantities of women's clothing are made in Cleveland. Slaughtering and the wholesale meat-packing business are other important industries. [Illustration: THE UNIVERSITY CIRCLE]
