DETAILS. 



In the further descriptions of the brown ores of this valley 

 they will be referred to their proper horizons, in connection 

 with the locations in which they are found, and in consecu- 

 tive order from the head of the valley to its 8. W. end. 



That portion of the valley lying N. E. of the Locust Fork 

 of the Warrior river, called Bristow' l s Cove, exposes no brown 

 ores on the surface. They very probably exist there as in 

 other parts of the valley, but the uplift there has not been 

 sufficiently great to bring the main brown ore bearing hori- 

 zons to the surface. 



Only on the west side of the cove, at the foot of Sand 

 Mountain on lands formerly belonging to Levi Murphree, 

 deceased, there is a large show of spathic iron, it belongs 

 to the 6th Limonite horizon. If the 5th horizon carries brown 

 ore here, it is covered up by the drift and silt of Sand val- 

 ley, and does not show on the surface! The oldest rocks 

 exposed in the Cove is the top of the Trenton, hence the 

 great brown ore bearing strata can not be seen. 



On the S. W. side of the river, about one mile south of 

 where it cuts the rim of the valley, in S. 9, T. 11, R. 3, E., 

 on the face of Sand Mountain, there is a good show of good 

 brown ore, It belongs to the upper or 6th horizon. The 

 quantity, as shown scattered along the face of the mountain, 

 and its quality exceeds what is usually found in this horizon. 



In S. 15, T. 12, R. 3, E., on the lands of Wiley Bynum, is 

 a deposit of brown ore of considerable extent, but uncertain 

 thickness. It is generally very good ore, imbedded in rich 

 red ochre ; bed not cut through, or any exposure- made that 

 would show its thickness, or give any approximate knowledge 

 of the quantity of the ore. So far as cut into, it showed 

 chunks of small size, smooth and regular, and shot ore with 

 but little admixture of chert or rock. This deposit belongs 

 to the third horizon. 



A little farther to the S. W. in S. 18, T. 12, R. 3, E., is a
