72 GEOLOGICAL SURVEY OF ALABAMA. 



limestone is sufficient to contain the Clinton, then we may 

 be assured of its presence, though covered by debris of other 

 formations. In the S. E. i of Sect. 12, this limestone and 

 the Lagrange sandstone come together; the Clinton and 

 Lower Siliceous therefore have both gone down in the fault. 

 In a portion of section 13 only a part of the Clinton has dis- 

 appeared. A little farther S. W., in the same section, the 

 Clinton comes up in a bold ridge, with Lower Siliceous Chert 

 scattered over its surface. Several openings have been made 

 here; ore generally shaly and poor. The top bed measured 

 two feet; ore of fair quality. In these two sections 12 and 

 13 much labor has been lost in searching and digging for 

 iron ore. Not because it does not exist, but because the 

 labor was not expended in the proper places. 



In the S. E. of S. 13 there is a notable example of the 

 Clinton, after being for a space engulfed in the fault, again 

 coming above. the surface near the Chepultepec and Spring- 

 ville road. For a quarter of a mile the Clinton does not 

 show, it is below the surface; then it rapidly rises into a ridge 

 70 feet high. Near the N. E. end of this ridge, in a pit, its 

 strata were seen dipping N. E. 75. In a short space farther 

 to the S. W., or down the ridge, it resumed its u^ual N. W. 

 dip. It was very evident, therefore, that the N. E. end of 

 this ridge had been forced up, almost vertically at the end 

 of the submerged portion. It makes a prominent ridge for 

 over half mile. In the eastern part of section 23, most of 

 the Clinton is again beneath the surface. 



In the S. W. of N. E. i of S. 23 T. 13 R. 1, E; on the lands 

 of J. P. Box, the iron ore beds are again brought to the 

 surface. A bed of hard, solid, rough ore, was here seen two 

 leet thick, lying close to the Black Shale, with no visible 

 intervening rocks. It is certainly the bed classed as No. 1 in 

 the general section. The nonexistence of roofing rocks above 

 it is a local peculiarity. On the same tract at a lower level, 

 a bed of similar ore was seen, of about the same thickness. 

 It is probably the same bed. The rocks were not exposed 

 so as to decide definitely ? and relative levels, afford no criterion 

 for identifying ore beds on this- side of the vallev. The
