MURPHREE'S VALLEY; ECONOMIC GEOLOGY. 55 



normal position and coincides in no respect, either with 

 the axis, or general uplift of the vallev. Almost opposite 

 the western end of this ridge a gap exists in the Sand Moun- 

 tain, and nearly due South from that is the sink in the Red 

 Mountain, and across the valley still South is Clowdus' Gap 

 in the Straight Mountain. It the reforeseems probable that 

 all these abnormal features here may have resulted from a 

 fault running North and South, with diverse displacements. 



This sink in Red Mountain is in S. 1, T. 13, R. 1 E., half 

 a mile West of Oneonta. Very little iron ore comes to the 

 surface in this section. It is generally buried too deep 

 under the Siliceous chert to be seen, or perhaps ever to be 

 made available. In Section 2 adjoining on the west, good 

 out crops of the top bed are seen all along the face of the 

 mountain. Cuts were made in this bed at two places, in this 

 section, and the ore found of nearly average quality. 31 

 inches thick at one and 36 at the other. Near the middle 

 of Section 2 there are two gaps in the Clinton close together: 

 between them, a point much denuded, showed the strata 

 very plainly. The top bed, or No. 1 of the general section, 

 is three feet thick, No. 2, 10 to 12 inches. No. 3 shows 

 plainly, but was not opened. No. 4 carries soft, dark grey 

 ore, and iron limestone, alternately. It was only very 

 slightly opened, and sectional measurements could not be 

 made. The whole thickness was estimated at ten feet, of 

 whiten two feet of good, soft ore were exposed. The. iron 

 limestone is of good quality, and carries more than the usual 

 per cent of iron. The 5th bed does not exist at this place. 

 The indications however show that it begins a very short 

 distance below this point, and continues for several miles 

 down the mountain. In the remainder of Section 2 no 

 openings had been made, but beds 1 and 2 crop out all 

 along near the top of the mountain. 



In Sect. 10, same Tp., several pits were sunk in the ore 

 beds, and gave the following measurements : 



Bed No. 1. Four feet one inch, with a two inch clay part- 

 ing in the middle, about average quality.. Intercalated bed, 

 one foot, reddish hard ore.
