EXHIBITS IN MINES AND MINING BUILDING. 469 



ful rubidolite, or pink tourmaline, are displayed at the entrance. 

 Elsewhere in the building is a fine and beautiful exhibition of 

 the so-called "onyx" from New Pedrara, in Southern California. 



Besides the California exhibit in the Mines and Mining 

 Building, an interesting collection of the mining products of the 

 state, especially gold ores and native gold, are contained in the 

 California state building. Somewhat similar specimens, how- 

 ever, are in the Mines and Mining Building, so that the division 

 of the collection in this case is not especially injurious. 



Among the foreign collections, that of New South Wales 

 stands preeminent. The great mining wealth of this province 

 is exhibited in a very systematic and thorough manner, and an 

 excellent idea is given of the resources of the region. There is 

 no attempt at a display of a sensational character as is seen in 

 some of the exhibits, but everything is shown in a plain business 

 way, in large quantities and in properly selected samples. 

 Among the most prominent features of the exhibit are its tin, 

 gold, silver, lead, antimony, copper, iron, manganese, and chromium 

 ores, its coal, graphite, building stones, etc. The ores exhibited 

 are average samples such as are sold in the market, and there- 

 fore give a true idea of the deposits represented. In many 

 cases, as in antimony, tin, etc., the metals are exhibited in blocks 

 or pigs, with the ore from which they are derived. The ores of 

 the great Broken Hill silver mine and the statistics of its pro- 

 duction are of interest to those acquainted with this famous 

 mine. The exhibit of the tin industry is of great interest as rep- 

 resenting the development of this comparatively new tin region, 

 which has only been much developed since 1872; while the coal 

 exhibit shows not only the bituminous coal of the region, but 

 also the kerosene shales, etc. 



Among some of the other foreign exhibits those of the prov- 

 inces of Ontario and Quebec are very good, showing as they do 

 the various products of those provinces in a thorough and syste- 

 matic order. The other provinces of Canada do not make such 

 good exhibits. A collection of the rocks of Canada by the Geo- 

 logical Survey is of great interest. Mexico exhibits a great
