MESSES. AENOLD-BEMEOSE AND NEWTON ON AN [Feb. I905, 



Layer No. I (PL Y, fig. 1) was here 2 feet 5 inches below the 

 roof of the cavern. The layers were not horizontal, but dipped 

 south-south-eastward, so that as we worked farther into the cavern 

 towards the north-north-west they rose, and at a distance of 15 feet 

 from the door layer No. I was touching the roof. These layers, with 

 the exception of No. V, were traced to a distance of 18 feet from the 

 door. They then became so indistinct that it was impossible to 

 t ace them farther. At 20 feet from the wooden door we reached 

 the fissure or swallow-hole. The 142 bones from these 2 feet 

 (namely, between 18 and 20 feet from the door) were therefore kept 

 separate (Table I, col. 8, p. 58). The 2 feet of deposit (measured 

 horizontally) consisted of clay with bones and large angular blocks 

 of limestone. At a distance of 16 feet from the door we found a 

 layer of stalagmite, 1 to 3 inches thick, and below it an angular 

 limestone-gravel cemented together in places by carbonate of lime. 

 Neither of these layers contained bones ; but 138 bones were 

 obtained from the clay immediately above the stalagmite, and, 

 as we could not correlate this clay with any of the other layers, 

 the bones from it were kept separate (Table I, col. 6). The 

 stalagmite-layer extended for a distance of about 12 feet to the 

 north-north-west : at 16 feet from the door it was 3 feet below 

 the top of breccia No. III. As the breccia was 2 feet thick and 

 layer No. V was 14 inches thick, this layer No. V had apparently 

 thinned out. Layers Nos. 6 & 8 were very near together, the 

 bones from No. 8 being obtained from a place about 2 feet above 

 those from No. 6. 



Entrance or Swallow-Hole. 



The width of the swallow-hole, which communicated with the 

 ground-surface near the top of the quarry, measured in the same 

 direction as the length of the cavern, was 7 j feet ; and from this 

 980 bones were obtained (Table I, col. 7), all above the line AB in 

 PI. V, fig. 1. The upper part of the material filling the hole consisted 

 of large masses of cherty limestone with clay, and rested upon the 

 stalagmite (Table I, col. 6) to the south-south-east. In the north- 

 north-western portion of the swallow-hole only three layers could be 

 distinguished, namely, (1) clay, (2) clay with bones, and (3) gravel 

 (angular). The layers in the swallow-hole formed a slight anticline, 

 dipping south-south-eastward and north-north-westward. To the 

 north-north-west of the swallow-hole only about ten bones were 

 obtained ; the deposits in that direction consisted of clay with large 

 blocks of limestone, and a hard rubble with pieces of chert. Some 

 17 feet north-north-west of the swallow-hole, the cavern narrowed 

 to a width of 2 or 3 feet, and a short distance farther on died out 

 into a small joint. 



A ground-plan of the upper part of the cavern, along the line AB 

 in the horizontal section, is reproduced in PI. Y, fig. 2.
