GEOLOGICAL REPORT. 67 



COPPER. 



We observed several localities in the South-west, in which 

 were found small quantities of both the sulphuret and the car 

 bonate of copper ; but none of them give evidence sufficient to 

 justify the opinion that the deposits are very extensive. 



In Taney county small quantities of copper ore were observed 

 at McFadden s Mines and at the Goose Diggings. In Lawrence 

 county, at several localities on the Turnback, this ore was found 

 near the junction of the Encrinital and Chemung rocks, -]-&amp;gt;&amp;lt; 



Mr. Broadhead examined several localities in Bade and 

 Green. The following is an abstract of his report : 



REPORT OF LOCALITIES EXAMINED BY G. C. BROADHEAD. 



&quot; In Dade county, at Josiah Stogdill s, on S.W. of N.W. qr. 

 Sec. 2, T. 30, R. 25, copper ore occurs in small crystals of sul 

 phuret and particles of green carbonate, profusely disseminated 

 through a very coarse and -somewhat friable crystalline lime 

 stone, belonging to the lower Encrinital beds. Along a branch 

 running near, copper has been found in several places. On 

 S.E. of N.E. qr. Sec. 23, T. 30, R. 25, sulphuret of copper is 

 found, associated with brown hematite. 



&quot; Green county. On Sec. 19, N.W. of S.W. qr. T. 30, R. 24, 

 very small traces of copper were found associated with calc 

 spar, and traversing the lower silicious beds ( c Turnback 

 rocks ) of the Encrinital limestone in about an E. and W. 

 direction. 



&quot;At William Haralson s, on W. lif. of Sec. 10, T. 29, R. 24 

 W., a pit has been sunk fourteen feet deep through the lower 

 beds of the Encrinital limestone. The ore found here is the 

 sulphuret and green carbonate, in a gangue of coarse opaque 

 buff-colored calc spar, adhering to large crystals of white sub- 

 transparent calc spar, the copper ore more often occupying the 

 line between the two varieties of spar. Some mining has been 

 done here, but no profitable results have as yet been derived. 

 This shaft was sunk in the edge of a valley leading into the 

 valley of Sac river, and about three-fourths of a mile from that 

 stream. Fragments of copper ore have been found at several 

 places along this valley. In Sec. 2 ; T. 40, R. 9 W., in Maries
