eral thing, and do not offer such great chances for luck 

 as the more precious minerals do. 



A visit to any of our leading coal mines or iron mines, 

 and a study of the great amount of work done and the 

 way everything is managed, will convince any person of 

 intelligence that their success depends almost, if not en- 

 tirely, on the management. 



The St. Jo Lead Company, of Missouri, is one of the 

 best managed works I have ever visited. It is wonderful 

 to see the way the ore is mined, crushed and pulverized, 

 and a profit obtained from lead, containing no silver, in 

 these days of cheap lead. Every use is made of science 

 and invention up to date. 



Electricity, diamond drills, improved machinery, and 

 men of brains with only one object in view tell the 

 whole story. 



Rock mixed with galena and so poor that no other con- 

 cern in the world could work it without loss, is mined, 

 hoisted out, dumped into crushers and scarcely touched 

 by human hands until it has passed through the various 

 operations of the mill and comes out separated into two 

 substances fine as meal; one is galena and the other rock. 

 Brains and machinery, driven by the skill and energy of 

 a ruling mind, do the whole business. 



The very men who invented and built the machines 

 could not run them as successfully as is being done at 

 this place. Other mines have tried it and failed. I 

 have known one of the leading mineralogists of 

 Europe, Dr. Stapf, of Sweden, who came to this country 

 twenty years ago to take charge of some mines in Mexico 

 for a New York company. He built a concentrating 

 machine at Bethlehem, Pa., which was spoken of very 

 highly by the U. S. mining reports, and published draw- 

 ings made of it and a long account of its performance 

 during a trial at Bethlehem, and it was undoubtedly a 

 perfect machine for its work, which was to separate
