ANALYSIS OP THE lEON ORE, OF lEON RIDGE. 



BY PROF. J. L. CASSELS, OF CLEVELAND, OHIO. 



Milwaukee, Oct. 5tli, 185 T. 

 Deak Sir: 



Learning that Prof. J. L. Cassels of Cleveland, Ohio, had 

 made very careful analysis of six different specimens of the 

 ore from Iron Ridge, in this State, and knowing the deep in- 

 terest felt by our citizens in these very valuable and easily 

 worked mines, I requested him to furnish the results for pub- 

 lication in the forth- coming volume of Transactions of the Wis- 

 consin State Agricultural Society. This he has done, with the 

 consent of the company for which they were made, and I for- 

 ward his letter herewith for publication, as indicated above. 

 This is perhaps due to Prof. Cassels, and it becomes the more 

 important, inasmuch as his f >rmer very partial and incomplete 

 analysis, made for a specific object only, has been extensively 

 published, and has led to incorrect conclusions in regard to the 

 value of these ores. Very truly yours, I. A. LAPH AM.
