EXHIBITS IN MINES AND MINING BUILDING. 463 



of Harriman, Tenn.," and shows the coal, coke, fossil and mag- 

 netic 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 min- 

 ing 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 attrac- 

 tive 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 exten- 

 sive 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 repre- 

 sented ; 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,
