ite), the manganese ores, zinc ores, clays, fire-brick, and slate of 

 that state are represented. The Bertha Zinc and Mineral Com- 

 pany displays the zinc ores of the southwestern part of the state 

 and the spelter made from them, as well as statues, wire, etc., 

 made from the spelter. 



West Virginia makes a fine display of coal and coke, at pres- 

 ent two of its most important industries. Such an exhibit is very 

 appropriate when we consider that forty-eight out of the fifty- 

 two counties of the state are said to contain more or less coal. 

 The salt, mineral waters, crude and refined oils, iron ores, and 

 building stones are also displayed. 



North Carolina makes a very neat and characteristic exhibit 

 of iron ores, auriferous quartz, mica, kaolin, asbestos, building 

 stones, gems, etc. The gems include diamond, sapphire, topaz, 

 ruby, beryl, garnet, rutile, chalcedony, etc. A number of inter- 

 esting models of gold nuggets are also displayed. A number of 

 photographs of different districts form a part of the exhibit, 

 which is neatly and systematically arranged. 



South Carolina makes a good exhibit of its great phosphate 

 industry, displaying the crude phosphate and also the manufac- 

 tured superphosphate. The phosphate industry far eclipses in 

 importance all other mining industries in that state, and the 

 others, such as gold, iron, and manganese mining, in the western 

 part of the state, are of very little and very unstable importance, 

 and are not represented. 



Florida, long unknown to the mining industry, has suddenly 

 become of great importance on account of the recent discovery 

 of its phosphate deposits. A small exhibit of these phosphates 

 is made in the Mines and Mining Building, but it is not suffi- 

 ciently extensive to do credit to a young and rapidly growing 

 industry. 



Louisiana makes a very appropriate exhibit of its mining 

 products, among which are lignite, oils, salt, sulphur, marls, clays, 

 chalk, building stones, grindstones, mineral waters, and other 

 minor materials. 



The Tennessee exhibit consists mostly of a "Mineral Exhibit
