EXHIBITS IN MINES AND MINING BUILDING. 465 



zinc spelter are displayed with the ores from which they are 

 derived. A model of the dressing works of the Saint Joseph 

 Lead Company and a relief map of Iron Mountain, colored to 

 show its geology, are interesting features of the ^exhibit. The 

 coal industry of the state is also represented, together with a 

 number of building stones, ochres, etc., and a fine collection of 

 calcite and other mineral specimens from the lead and zinc 

 mines. 



The South Dakota exhibit consists largely of tin ore, aurif- 

 erous quartz, mica and some argentiferous galena, and is 

 essentially a Black Hills exhibit. " Lode " tin ore and stream 

 tin, as well as pig tin manufactured from the ores, are exhibited 

 in large quantities. A large column of tin ore, from the property 

 of the Harney Peak Consolidated Tin Company, contains a 

 placard stating that the capital invested is $3,500,000, a fact 

 it is difficult to understand they should wish to make so promi- 

 nent in view of the unproductive history of their operations. 

 The auriferous quartz is a good exhibit and characteristic of the 

 quartz deposits of the Black Hills. Some beautiful pieces of 

 Arizona silicified wood, which were polished in Dakota, are 

 exhibited, but in lack of the proper explanation as to their source, 

 they are misleading, as they suggest Dakota as the region from 

 which they were derived. 



Kansas makes a very good exhibit of lead and zinc ores with 

 the pig lead and zinc spelter derived from them. The exhibit 

 also includes a display of rock salt, gypsum, building stones and 

 other minor products. The exhibit is small, but it is character- 

 istic of the state and is well arranged. 



Montana makes a good exhibit as far as it goes, but many 

 localities and many important deposits are not represented. The 

 best exhibits are from the great mining camp of the state, 1. e., 

 Butte City. The great copper and silver interests of this district 

 — especially the former — are well presented, and large quan- 

 tities of sulphide copper ores, and the metallic copper made from 

 them, are displayed. A quantity of gold quartz, and an inter- 

 esting collection of gold nuggets are also a part of this exhibit.
