EXHIBITS IN MINES AND MINING BUILDING. 4&7 



The New Mexico exhibit contains some good material, but 

 is not very well exhibited. The silver ores, one of the most 

 important products of the territory, are well represented, being 

 grouped according to the localities from which they came. A 

 small cabin in the centre of the exhibit is composed of silver, 

 lead and gold ores from different localities. A stuffed burro 

 carrying a prospector's camping outfit is a somewhat sensational 

 feature of the exhibit. A column of coal from Blossburg and 

 Los Cerillos represents the growing coal industry of the terri- 

 tory. 



The Arizona exhibit is very good and well arranged. It is 

 truly indicative of the products of the territory. The most im- 

 portant features of it are the copper ores, the silicified wood and 

 the gold ores. The copper ores especially are well represented, 

 and a beautiful column of green and blue carbonates of copper 

 from Bisbee forms the most prominent feature of the exhibit. 

 While in the Michigan exhibit we see only native copper, in the 

 Montana exhibit only sulphides of copper, here in the Arizona 

 exhibit we see mostly carbonates of copper with some silicate 

 and oxide of copper. Thus in these three copper districts we 

 have representatives of three great classes of copper ores. An 

 interesting feature of the Arizona copper exhibit is a series of 

 models showing the underground workings of the Copper Queen 

 Consolidated Mining Company at Bisbee. The Old Dominion 

 Copper Company whose mines are at Globe, Arizona, makes a 

 very excellent exhibit of its ores and its copper ingots in a cabinet 

 alongside the main Arizona exhibit. The gold ores of Arizona 

 are well represented, and some of the silver ores are also shown, 

 while the beautiful polished sections of the celebrated silicified 

 wood of Arizona form an attractive and interesting feature of 

 the exhibit. Some of the so-called "onyx" is also exhibited 

 in polished slabs. 



Nevada makes a fairly good exhibit of its mining products, 

 mostly the silver ores abundant in this region, and the accom- 

 panying minerals. A "special exhibit" from Eureka, Nevada, 

 contains a number of interesting specimens.
