GEOLOGICAL REPORT. 41 



as many as 500 men have been engaged in mining at one time. 

 The mining has all been confined to surface diggings. East of 

 this place, in Sec. 33, is a crevice containing a vein of lead five 

 inches thick, adhering in a vertical sheet to the Magnesian 

 Limestone. In N.E. of N.E. qr. of the same section, lead has 

 been raised. 



" Williams' Mines, located west of Mineral Hill, in Sec. 32, 

 T. 40, R. 2, were opened in 1851, and up to April, 1854, the 

 amount of ore raised was 202,183 pounds. During the re. 

 mainder of 1854 there were raised 145,000 pounds. The course 

 of the line of shafts and tunnels bears N.E. and S.W. The 

 mineral was first procured 25 feet below the surface, and the 

 deepest workings were 75 feet below the surface. The mineral 

 is found in fissures of irregular dimensions, varying from two to 

 eight feet in width, and three to four in height. It occurs in 

 veins ranging through red clay, associated with brown hematite, 

 pyrites and ochre. These mines have not been worked to any 

 extent during the last three years. 



" Nearly every portion of Sees. 32, 33, and 34, T. 40, R. 2 W., 

 contains more or less lead. In the N.E. qr. of Sec. 1, T. 40, 

 R. 2, there have been raised 10,000 pounds of ore. 



"Wetti's Diggings are located in S.E. of S.E. qr., Sec. 3, 

 T. 38, R. 2 W. During the winters of 1856 and 1857 about 

 135,000 pounds of ore was raised. 



"Murirey's Diggings are situated north of Wein's Diggings, 

 in the same section. A great deal of ore has been obtained 

 here from surface diggings ; but no mining has been done 

 lately. On S.E. qr. of S.E. qr., T. 37, R. 2 W., about 200 

 pounds have been obtained from shallow diggings. 



"Halberfs, in S.E. Sec., T. 37, R. 4. In 1844 from 3,000 to 

 4,000 pounds were obtained here from surface diggings. 



Evam\ in N.E. of Sec. 3, T. 37, R. 3. In 1856 about 300 

 pounds were obtained from surface diggings. 



"Ransom's Mines, (examined by Mr. Englemann,) in Sec. 

 15, T. 38, R. 2 W. The ore is found in the upper part of the 

 3d Magnesian Limestone. The mineral is supposed to occur in 

 horizontal sheets, connecting with pockets. About 54,000
