tinctly cliipped fragment of black lava was 

 found six inches below the surface. Asso- 

 ciated with it were splintered bones and re- 

 mains of extinct mammals. It is possible that 

 the flint may have fallen in from the surface 

 or worked its way there through a small crevice 

 in the floor, but before commencing excava- 

 tion the floor had been cleared of all loose ma- 

 terial and no crevices were observed. While 

 not of the most conclusive character, the evi- 

 dence seems to favor original association of 

 the objects found. Bones of several extinct 

 mammals were found cemented to the top of 

 the stalagmite capping.

The materials in the fissure deposit had ac- 

 cess at some remote date through an opening 

 in the roof. Of this no trace can now be 

 seen, owing to stalactitic growth. Its source 

 was indicated by streams of bones and earth 

 found on projecting ledges and in pockets in 

 the fissure walls. 



On the sides of the chamber opposite the 

 fissure several small openings lead to a lower 

 series of galleries, in one of which a large 

 pool of water winds among the rocks. At two 

 places in the lower , labyrinth of galleries 

 there are deposits similar to that in chamber 

 one and from these bones and teeth were taken. 

 From the position of these deposits they ap- 



pear to have entered through fissures leading 

 from some other chamber or from the surface. 



High on the south wall of chamber one and 

 ditficult of access is an entrance to a second 

 and larger cavern. This has a high arched 

 roof and several tunnel-like grottos lead from 

 it. Through a crevice caused by a fault, a 

 great quantity of earth, angular limestone 

 fragments and gravel have partly filled this 

 room. 



At the farthest end of one of the grottos is 

 an oval pit-like opening, which seemed to cor- 

 respond to the description of the well into 

 which the Indian maiden fell. To explore this 

 pit, holes were drilled in the hard floor of the 

 grotto and into these steel pins were set for 

 the support of a rope ladder. The well was 

 found to widen towards the lower end and was 

 really but the chimney of a large cavern. The 

 skeleton of the Indian maiden lay imme- 

 diately below the opening and over the greater 

 part of the floor were strewn many bones of 

 bear, cougar and a large extinct goat-like 

 animal.* 



The deposit on the floor of this chamber is 

 an accumulation of mud, stalagmite and 

 gravel. This has been excavated, in places, to 

 a depth of four feet, and in that thickness 

 shows six distinctly separated layers of clay, 

 breccia and stalagmite. 



Mammal remains were very abundant over 

 the floor and through all the strata excavated. 

 In many instances whole skeletons of car- 

 nivores and of rodents were found. There 

 are many complete skulls and numerous disso- 

 ciated limb bones. The stalagmite encrusting 

 some of the specimens was from one to two 

 inches thick, the bone below the covering 

 being in a perfect state of preservation. 

 Among the fragments are numerous split 

 bones. Some specimens show scorings of ro- 

 dents' teeth and others bear marks made by 

 the gnawing of large carnivores. 



Following is a provisional list of species 

 from this chamber (No. II.) : 



Ursus n. sp.
