60 GEOLOGICAL SURVEY OF ALABAMA. 



movement ceased, (if it has yet ceased,) cannot have been 

 a very long one, or these falls would have been farther up 

 the streams. 



In Section 31, same Township, the 4th bed continues to 

 be the most prominent. It still carries hard ore, but has less 

 silica than near to, and beyond the river. ' It is evidently 

 improving in quality, but has not diminished in thickness. 

 The top bed which, for some distance back, had been abraded 

 from the top of the mountain, and its out-crop buried by the 

 debris on the other side, is again seen on the top of the 

 mountain. Its thickness is less, and its quality inferior to 

 what it is toward the North-east corner of the Township. 

 About the same as it was seen in Section 16. Though it is 

 probable, that at and near the out-crop here, for want of 

 roofing in with bard rock, a fair sample of the bed has not 

 yet been reached. Only a small portion of this section is 

 on the Red Mountain, and the Clinton enters the next Town- 

 ship near the North-east corner of Section 1 of Township 14. 



In T. 14 of R. 1 W., the Clinton presents much variation, 

 and will have to be described in detail. In S. 1 the 4th bed 

 is still the most prominent. In some places great masses of 

 it have slid far down the mountain, and are thickly strewn 

 along its South eastern base. The ore is softer than we have 

 seen it in Township 13, but yet carries too much Silica. It 

 .is estimated to contain 30 to 35 per cent, of iron. The 3rd 

 bed was not seen here. And the 1st and 2nd were of little 

 importance. In this Section the iron limestone, which has 

 been found occasionally, as a thin member, in the Township 

 above, now begins to thicken, and become prominent. In 

 Section 11 it occupies a large space. Its thickness where 

 seen to the best advantage, was about 50 feet. It all carries 

 some iron, but it is unequally distributed. Some portions 

 of the edge have much more iron than others, in some parts 

 it is streaked with hard carbonate of iron and sand. All of 

 it here has much sand, which will probably render it unfit 

 i'or furnace use. It would make a very pretty building rock, 

 but its hardness and grittiness would make it very difficult 

 to dress, and it would not be durable. The iron and lime of
