12 PROCEEDINGS OF THE DENVER MEETING 



exposed in the gorge or canyon of the Ocoee river along its winding course of 12 

 to 13 miles through the Unaka mountain range. This appears to be a natural 

 grouping, and I have seen as yet no justifiable reason for changing the name, so 

 far, at least, as Tennessee and contiguous states are concerned. 



"Chilhowee sandstones" is an appropriate name and one which has stood. a 

 test of time. A few years since the idea was advanced that the sandstones and 

 sandy shales of the Chilhowee mountain and its congeners were the offshore de- 

 posits of certain Upper Silurian formations ; but it has been shown that this can 

 not be the case. They may be offshore deposits, but are of far older date. 



Very curiously, the name Chilhowee has been objected to on the ground that 

 the formation has been called by several names ; hence it was argued that Chil- 

 howee ought to be dropped and another name taken. This procedure ignored the 

 fact that the name Chilhowee had been used for the formation for many years 

 before the others were even thought of. Furthermore, some of the names resulted 

 from errors as to the age of formation. Briefly, the dropping of the name Chil- 

 howee is not justified. 



" Sevier shale" ought to be numbered 9, with perhaps the exception of its top- 

 most part. 



The name " Stones river " was used by me in a report published in 1856..* It 

 was made to include certain bluish and dove colored limestones — in all, about 300 

 feet thick and outcropping chiefly along the course of Stones river, f in Rutherford 

 county, Tennessee, and the lowest to be seen in the central part of the state. 



It included also the Carter (Carter limestone) of the table. In my larger report 

 of 1869 1 it was not used, the name " Lebanon " being substituted. 



On the suggestion of Mr E. O. Ulrick, who had personally examined the lime- 

 stones along the river and had carefully studied their fossils, both those acquired 

 by him and those of my own cabinet, I restored my old name, " St&nes river." In 

 fact, Mr Ulrick had already made use of it in his writings. The name is especially 

 appropriate to the geological and paleontological conditions present. 



" Capitol, Mount Pleasant phosphate," is the^rs^ phosphate met with in ascend- 

 ing the Tennessee series of rocks. \ 



" Hudson, Hudson phosphate," is the second phosphate ascending. || 



"Camden chert" is a very fossiliferous chert, well characterized and a new 

 member in the Tennessee series of formations, 50 to 100 feet in thickness.1| 



" Hardin sandstone " is generally a fine grained, bituminous, grayish sandstone, 

 locally running into the phosphate above it. It is a new member of the Tennessee 

 series. In Hardin county it reaches a thickness of 12 to 15 feet. 



The three formations— the Hardin sandstone, the Swan Creek phosphate, and 

 the Black (Chattanooga) shale — are related. They are more or less phosphatic, 

 abound in a small lingula, apparently the same in all, and, furthermore, are locally

f Stone's or Stones river, not "Stone river," as erroneously given in some histories. We ought 

 to read, for example, the battle of Stones river, not of "Stone river." It is Stones river, so 

 named in honor of a Mr Stone, one of the pioneers who first explored the section of Tennessee 

 through which the lower part of Stones river runs, and not because it has a stony bed.
