750 GEOLOGY AND TOPOGRAPHY OP THE LEAD REGION. 



The amounts smelted by Richards & Co., at their furnace in Warren, Illinois, are ap- 

 pro>:imately as follows : 



Toar. Pounds. Tear. Pounds. 



1873 450,000 1875 250,000 



1874 300,000 1876, to October 1st. .. . 200,000 



Inasmuch as no detailed statements could be obtained from any of these parties, or 

 anything more than the foregoing approximations, it is impossible to give a correct and 

 rehable account of the several amounts they have smelted since 1862. By comparing 

 their present product with that of otlier parties in former years, it is estimated that 

 they have smelted, since January 1, 1862, about one hundred million pounds. 



As it is a matter of interest to compare the present production of the mines with t].io 

 past, 1 have taken the Uberty to reproduce the following statistics of the Upper Missis- 

 sippi Lead mines, the product being given in tons of metallic lead.'
