of Harriman, Tenn.," and shows the coal, coke, fossil and magnetic iron ores and brown sandstone produced in that district, together with the pig iron manufactured. The exhibit is creditable to Harriman, but it is a pity that the state of Tennessee in general did not make a full display of its coal, iron, marble, and many other mining resources. The Cleveland Fire Brick Company of Cleveland, Tenn., makes an exhibit of its clays and bricks.

Kentucky makes a good and extensive exhibit of coal and coke, with smaller collections of iron ores, building stones, clays, bricks, etc. A relief map of the state is also an attractive feature of the exhibit. The exhibit contains a large amount of good material, but it might be displayed to better advantage.

Ohio makes a good exhibit of coal, its most important mining industry, and also displays on a smaller scale its crude and refined oil, its salt, clays, iron ores, whetstones, etc. It presents a good model of a salt refining works, and makes a very attractive display of the bricks, tiles, etc., made from its clays.

Indiana makes a good business-like exhibit of just what it has and no more, including a display of coal, clays, building stones, oil, mineral waters, and tiles, and glass manufactured from native products. The exhibit is well arranged and shows all that is necessary.

Illinois makes an extensive display of its clays and the various manufactured articles made from them. A much more extensive mining, mineralogical, and geological exhibit of the state is made in the large state building elsewhere on the World's Fair grounds. This exhibit is well arranged, and truly indicative of the products of the state.

Michigan makes one of the most elaborate exhibits of all the states. The three great mining products of this state are iron, copper, and salt. The first two are excellently represented; the last is much neglected. The different kinds of iron ore are illustrated with numerous specimens; and a large colored cross-section of the Cleveland Cliffs Iron Company's mine is given. A wooden model of the No. 4 Ore Dock at Marquette,
