13, a. The other three are walled vaults. The largest, at the other 

 end of the row, was built up like a foundation wall of sandstone 

 slabs. It is rectangular in form, measuring on the outside 16 by 28 

 feet. All the walls are more or less destroyed ; the small portion of 

 one remaining is shown in plate 13, h. Two "walled-up graves" 

 reported on the first ridge north of Sugar Tree Camp, and one re- 

 ported on the first ridge south, never existed. There is a small cairn 

 on a high peak half a mile east of the camp. 



TICK CREEK CAVE 



In a ravine which joins Tick Creek about 2 miles from where the 

 latter flows into the Gasconade, and about 12 miles north of Arling- 

 ton, is a large cave known as the Saltpeter Cave. 



The opening is wide and high, but the mouth and floor are much 

 obstructed by large fallen rocks and the bottom is constantly wet 

 from wall to wall with running and seeping water. 



There is another entrance to this cavern around a corner of the 

 bluff and much higher up on its face. This opening is small and 

 the sloping passage from it to the cavern is almost closed in places 

 by drip formation. 



It was never inhabited. 



CAVE IN POOL HOLLOW (12) 



A mile east of Newburg a ravine now known as Pool Hollow, but 

 formerly called " Strawhorn's " [Strawhan's] Hollow, opens into the 

 right (north) side of Little Piney. Two miles from the river is a 

 cave at the head of a little cove. The entrance, facing directly 

 south and visible from half a mile down the ravine, is 12 feet high 

 and 75 feet across. The rear wall, where the cave makes a turn at 

 150 feet from the mouth, is plainly visible from the outside. 



At 60 feet within water reaches from wall to wall, and a constant 

 stream flows along the left side. The talus at the mouth is of tough 

 clay with many rocks scattered through it, and much of it has settled 

 back into the cave. Water drips from many places in the roof, so 

 that no part of the floor is ever entirely dry. 



Some broken flints and chips were picked up about the mouth and 

 in front of the cave, but nothing else could be found. 



In dry weather there might be spots which would afford a resting 

 place for campers, but'no continuous occupancy was possible. 



HOUSE MOUNDS NEAR ROLLA (13) 



Nearly 2 miles northeast of BoUa is the beginning of a little 

 valley which for a short distance is parallel with the Frisco Railway 

 and close to the right of way ; it then turns to the southward. Along
