small quantities has also been obtained in Sees. 26 and 27, 

 T. 40, R. 2 W. 



&quot; All the above mentioned mines occur in 3d Magnesian 

 Limestone. Lead has also been found at many places in 2d 

 Magnesian Limestone, but only in small quantities. 



&quot; Carbonate of Lead occurs in small particles at William s 

 Mines and at Mineral Hill. 



&quot;Phelps County. In a cave in Sec. 19, T. 36, R. 8, lead 

 occurs in small quantities, in a seam of Barytes, extending from 

 the entrance back for a distance of a hundred yards. In Sec. 

 35, T. 36, R. 9, a few pounds of mineral have been collected. 

 In Sees. 24 and 32, T. 39, R. T, a little has been found. At 

 all the localities in this county, the ore occurs in the 3d Mag 

 nesian Limestone. In Sec. 8, T. 39, R. 8, in Maries County, 

 Mr. Englemann reports the occurrence of lead in 2d Magne 

 sian Limestone. In 1856, about 350 pounds of mineral were 

 obtained here, and on Rocky branch upwards of 2,000 pounds 

 have been raised during one season. 



&quot;Lead has been found at but few localities in Pulaski County, 

 and in small quantities only. A few pieces were picked up 

 in Sec. 6, T. 35, R, 13. 



&quot; In La Clede County, lead was found in only one locality, 

 in N.W. qr., Sec. 5, T. 36, R. 16. At this place a few shallow 

 excavations have been made in the 3d Magnesian Limestone, 

 and a few pounds of the Sulphuret raised. The ore occurs 

 disseminated through an impure brown iron ore, a few hundred 

 yards distant from what appears to be a dyke of granite. 



&quot; In Wright County lead ore has been observed, in small 

 quantities, at several localities in the 3d Magnesian Limestone. 

 In S.W. qr., Sec. 11, T. 29, R. 16, Mr. Prock obtained about 

 150 Ibs of ore. It occurs in cavities, associated with calc spar, 

 in the Magnesian Limestone. Float-mineral has been found also 

 in S.E. qr., Sec. 11, and N.E. qr. Sec. 23, in the same town 

 ship. On Wood s Fork, about a mile and a half east of the 

 Webster county line, lead occurs in sandy textured magnesian 

 limestone rock. It has also been found at several other places 

 in the same strata ; it occurs in irregular masses, resting in 

 cavities in the Magnesian Limestone. In Sec. 23, T. 29, R. 14, 

 about 10 pounds of mineral have been found.
