GEOLOGICAL REPORT. 49 



different depths have been run, and the quantity of stoping 

 has been considerable. It has been, and is still, worked with 

 profit. 



" On this ridge, which belongs to the third Magncsian Lime- 

 stone, are three or four fissures passing down perpendicularly, 

 with a course varying but little from a due north and south, 

 and containing galena as far down as they have been explored. 

 They cover a belt of about 300 yards east and west, and though 

 neither on the top nor on the side of the ridge is there scarcely 

 any natural indication of their existence, they are found, under 

 ground, preserving a uniform course to the north, and one has 

 been traced and worked in this direction nearly 300 feet. 



" As we pass directly south from the Cove Mine, we travel 

 through the valley of the Meramec, and at a distance of about 

 half a mile we come to a lone, isolated hill, which, from its 

 total disconnection with all others, and its solitary appearance, 

 has been denominated the Lost Hill. This has a height nearly 

 equal to that of the ridge in which the above mines are situ- 

 ated, and in this it is reported that galena has also been found. 

 After leaving the Lost Hill, and travelling nearly due south, 

 we cross the Meramec, and in the bfuffs on the south side we 

 again find explorations for lead ore, nearly on a due south line 

 and about two and a half or three miles from Cove Mine. 



" Evans 1 Lode* The first point we reach on this ridge, at 

 which mining has been carried on, is what is known by the 

 name of Evans' Lode. The galena is found here, also, in a verti- 

 cal fissure, which has a width at some points of two feet. Its 

 course is nearly north and south. It is filled with clay, sul- 

 phate of baryta and mineral, and the galena is frequently in- 

 termixed with sulphuret and carbonate of zinc. The mining 

 here extends over a distance of 400 feet north and south, and 

 seven shafts, varying from thirty-eight to one hundred and 

 twenty feet, have been sunk, but three of which, however, are 

 connected with levels. The work has not been so systematical 

 nor so regular as at the preceding mines, and this it is reason- 

 able to suppose would be the case, inasmuch as it has not been 

 worked by the proprietor, but has been leased to different 

 parties.
