amusement erected and the surrounding grounds somewhat improved. 

 On account of all this, the place has become quite noted. At 

 present there is from 15 to 20 feet of loose stones and earth on the 

 solid rock floor, and a strong stream makes its way beneath them. 

 It could never have been occupied in prehistoric times until the 

 debris had practically reached the stage at which it was found by 

 the whites. 



Indian Mound Cave. — A report was received to the effect that 

 the mouth of a cave on the Stewart County line, about 18 miles 

 west of Clarksville, had been closed by a rock wall, and earth piled 

 against the outside of the wall ; also, that tool marks are quite dis- 

 tinct in a chamber which is plainly of artificial origin. 



The rock wall is the stratified rock, in place; the earth in front 

 has washed down from the hillside ; the tool marks are water chan- 

 nelings ; and other remarkable things mentioned in the report are 

 equally natural. The entrance is a narrow crevice. 



SULLIVAN COUNTY 



LiNviLLE Cave. — This is 4 miles almost directly west of Bluff 

 City. Apparently it is of great extent, for large sink holes con- 

 nected with it are scattered over an area of several hundred acres. 

 There are three principal openings. The largest is near the top of a 

 knoll or low hill, and is due to the falling in of the roof. The sunken 

 part has an area of about 30 by 60 feet. Usually, in such cases, the 

 debris entirely fills one end of the cavity thus made, obscuring that 

 part of the cavern, the other end being kept open by surface drain- 

 age. In this case, owing to the dip of the strata — some 8 or 10 de- 

 grees — and to a change in direction of the cavern at this point, both 

 ends may be entered from the fallen rocks and earth. At one side 

 the descent is precipitous and winding, over and among large fallen 

 rocks. No level place is reached in daylight. At the other side the 

 descent follows the natural dip of the strata and no level space can 

 be found from which the entrance is visible. This part, also, is 

 filled with rocks, large and small, from the roof and sides, and was 

 never habitable. 



Fifty yards from the main entrance is another much smaller cave, 

 on the slope of the knoll. It is at the bottom of a crevice 10 feet deep. 

 The floor is level, but only a few square yards in extent, the sloping 

 roof reaching it within 10 feet. As there is considerable drainage 

 into the cavity from the hillside, it is probable that this floor, at least 

 the upper portion, is of recent origin, and that the earth extends 

 downward indefinitely toward the subterranean stream. 



West of the knoll on which these openings are found is a valley 

 2 or 3 miles long. Timber shuts off the view toward its head. This
