amount of material, but it is so arranged that it loses much of 

 the benefit that it might afford to the exhibitors and to the 

 public. Brazil makes a fairly good exhibit, while Chile, Ecuador 

 and other South American countries are also represented. The 

 South Africa diamond exhibit is very interesting as showing the 

 mode of occurrence, methods of mining and washing, and cutting 

 the diamonds. The exhibits of Great Britain, Germany, Japan 

 and other foreign countries are also of interest. La Societe "Le 

 Nickel " of France makes a very interesting exhibit of its nickel 

 ore in New Caledonia, the nickel derived from it, pictures of 

 the mine and various other interesting features of the industry. 

 Many others of the numerous exhibits of American and 

 foreign products in the Mines and Mining Building might be 

 mentioned, but lack of space forbids further elaboration. The 

 same cause makes it necessary to discuss in another article the 

 extensive and excellent exhibition of the United States Survey 

 in the Government Building.
