56 GEOLOGY OF ILLINOIS. 



high faith in its own unyielding endeavors, has at last been rewarded 

 in the most ample manner, has its curious chapters bordering upon the 

 romantic. The story of unrequited labor must sometimes be written in 

 writing the history of the mines ; but far oftener the historian of the 

 lead mines may record that steady persevering effort hardly ever fails 

 at last in obtaining its rich reward. 



In addition to my own observations upon the geology of this county, 

 I take pleasure in acknowledging valuable aid derived from Mr. 

 HOUGHTON'S pamphlet upon the MARSDEN Mine, D. WILMOT SCOTT'S 

 little business directory of the county, the copy of '''Harper's Monthly 1 ' 1 

 above referred to, and suggestions obtained from Captain E. H. BEEBE, 

 of Galena, and Dr. LITTLE and HENRY GREEN, ESQ., of Elizabeth.
