THE MINES AND MBrALLURGY EXHIBIT AT THE PANANfA-PA- OTTO INTERNATIONAL EXPO SPTTON.

most instructive Of all the exhibits at the Panama-Paciffc International Ex- position at San Francisco is that of the United States Steel Corporation in the Palace of Mines and Metallur- gy. Here will be found models, ap- | paTatus. methods and finished pro- ducts, showing the processes of fabri- eating steel from the time, as raw product, it is dug from the earth until it is delivered to the ultimate consumer in one of hundreds of forms.
 This exhibit is the largest single exhibit in the entire exp osition, sev- eral of the subsidiary companies of the corporation being represented as well. The steel exhibit is installed within a facade of classic lines. In progressive order the visitor will see the iron ore mined in the vast open pit mines of the Vernilion and Miss abe ranges and the Sauntry-Alpena mines of Minnesota carried to the ore carriers of Lake Superior, to be taken to Duluth and refined, then to continue it's processes through the mighty plants of the steel industry. The successive stages of the fabri- cation of the steel will be shown in electric, Bessemer and open hearth furnaces. A blooming mill will ex- lets, bars, etc Special exhibits will show steel alloys, steel mine tim bers, wire,- cement made from fur mace sIag. bridges and many forms of steel construction, tin plate press ed steel and so forth.
 A factor in this immense exhibit is the models of mines, factory, ore docks, ore trains, steamer ore car riers, the work of s. George Stew ems ,said to be internationally noted in model work. Tn the model of the ore docks at Duluth, for instance. there are 25,ooo separate pieces of parts each made to an exact scale.
 This ore dock-the original has loading capacity of 5000 tons per hour.---wilI be shown in operation. In these 'sopen pft'' or surface mines of Minnesota more dirt. has been excavated than was dug in mak- l ing the Panama Canal
 The first exhibit to attract the wis 1 itor entering the main portal of the Palace of Mines will be the cornpre- l hensive display of the United States Bureau of Mines. The purpose of the Bureau in installing this exhibit IS to bring the people in close touch with the mineral industry and to fShow how the Bureau of Mines is 1 aiding the miner. It will be in two sections, one a model mine beneath l the floor of the building and the other a large rectang1e devotdd to me- taIIurgy In the rneta11urgicaI exhibit
 
 1 ize techinacl methods by demonstra- l ting the most efficient processes of l separating the metals. There will be l a great many assays and numerous working tests made all bearing on the study and solution of .Ineta11urgica1 I problems This area will be divided into elevnS departne
 The dem onstration mine is beneath l the building and will give the visitor an idea of the appearance of mine l and of the living and working condi- t1onS underground. It will be a faith l full replica with full size entries, drifts and stopes reproduced from ac- tua1 mines in the United States. It
 will be in every respect model mine operated under modern conditions with complete representation of the
 most efficient machinery and the
 methods employed. venti1ating sys- T tems and safeguarding of workmen will be irnpressively demonstrated.
 Admission to the mine will be free
 and by means of a regulation mine cage.
 In-t this underground mine the visi- tor will visit the Go1dde1d ConSolida-
 ted properties of Nevada, in faithful
 reproduction. He will see how the . pay ore is taken from the Home mestead mine: ho wlead and silver mining is 1 practiced in the Bunker Hill and Su1-
 Hvan Companys plant at . Kellogg
 Idaho; ore mining in the Copper
 Queen Consolidated mines at Bisbee
 Arizona. The. bituminous coal mines
 of the Pocohontas Consolidated Col Hers company of West Virginia, the Edkhrn mines of Kentucky and ths
 South Wyoming Coal Operators AS
 sociation's properties will complete { comprehensive exhibit of coal mining Motion pictures are to be provided shwing certain perations that it would = be impossible to actually reportray | h 17i1 hi 3f1A in,
