GEOLOGICAL REPORT. 55 



'28, there had been considerable digging. The mineral was 

 found in the clay. The deepest shafts were about fifty feet. 

 The diggings extended over an area of nearly ten acres, but 

 did not extend down into the rock. Mr. A. Chambers, who 

 worked these, obtained and smelted during the above years 

 40,000 pounds of mineral, and estimates the amount obtained 

 at other times, and hauled to other furnaces, at 25,000 pounds. 



"The Hamilton Mines, Town. 42 N., R. 1 W., Sec. 31, have 

 not been worked for the last six years. The digging was con- 

 fined to the clay, and the amount of mineral reported to have 

 been obtained was 100,000 pounds. 



"At Massey's Mine, Town. 41 N., R. 1 W., Sec. 14, one shaft 

 had been sunk sixty feet, but most of the other shafts were not 

 over twelve feet. Up to October, 1858, Mr. Massey estimated 

 the amount of mineral obtained at from 2,000 to 3,000 pounds. 

 They are much incommoded by water at these diggings. 



" Berthold and Generality's Digging's are near Mitchel's creek, 

 in Sec. 13, Town. 41 N., R. 1 W. They are principally on the 

 side of a hill. The deepest shaft was fifty-four feet, and which 

 was filled with water at the time of my visit, in October, 1853. 

 Mr. Generally gave, as the total amount of mineral obtained 

 here, 100,000 pounds.

LEAD FURNACES IN FRANKLIN. 



" Formerly, not only in Franklin, but also in other counties in 

 the mining region of Missouri, only the log and ash furnaces 

 were used. These have been gradually replaced everywhere, 

 excepting at one locality in Washington county, by either the 

 Scotch hearth or the reverberatory furnaces. The Scotch 

 hearth requires a blast, hence sometimes called the blast fur- 

 nace, and this is produced either by water or horse-power, or 

 by steam.
