LIMESTONES OF WESTERN TENNESSEE 68 1 



the Hardin sandstone, i foot thick, and the Black shale, 6)^ feet 

 thick. The fossiliferous part of the Linden bed is well exposed 

 also about half a mile northeast of this locality, in the woods. 



The Linden bed is exposed also on the eastern edge of Lin- 

 den, below the level of the town spring at the foot of the hill, 

 and thence eastward along the upper edge of the low bluff border- 

 ing the stream flowing from the spring toward the Buffalo River. 

 The thickness of the Linden bed at this point is about 1 1 feet. 

 Overlying it is a more massive rock, 2 feet thick, referred to the 

 Camden chert; followed by the Hardin sandstone, i8 inches 

 thick, and the Black shale, 6 feet thick, with numerous phosphatic 

 nodules at the top. 



About a mile east of Linden, on Short Creek, a quarter of a 

 mile west of the home of J. S. Journey, the Linden bed is 1 1 

 feet thick. It is overlaid by the Hardin sandstone, 2 feet thick, 

 followed by the Black shale. 



The Linden limestone evidently thins out rapidly eastward. 

 Half a mile east of the exposure west of the home of J. S. 

 Journey, at the top of a bluff rising above a spring along Short 

 Creek, east of the mouth of Jacks Branch, the Brownsport bed 

 is directly overlaid by the Hardin sandstone, 2 feet thick. Black 

 shale, 2 feet thick, and bluish sandy rock, 3 inches thick. No 

 Linden rock is found at the home of William Goodwin on Coon 

 Creek, 2^ miles northeast of Linden, or at the Webb or Rise 

 mill, half a mile south of Linden. It evidently thins out also 

 southward, since it is absent northeast of Lego, along a creek 

 also known as Short Creek. It is absent along the upper part of 

 the Buffalo River between Flat Woods and Riverside, and along 

 the upper part of Indian Creek above Olive Hill. 



From the limited evidence so far secured it appears that the 

 eastern line of outcrop of the Linden bed passes between^Linden 

 and the Rise mill, and then turns westward, crossing the Ten- 

 nessee River somewhere north of Lego. There is no evidence 

 of the presence of the Linden bed in the area between Browns- 

 port Furnace and Bath Springs. It is possible that the eastern 

 line of outcrop does not recross the Tennessee River north of 

 the mouth of Horse Creek. The Linden bed is absent along
