be measured. It is, however, not possible to ascertain exactly 

 the depth of the water and of the crack, since the water is 

 covered in part by the overlapping wall of the crack forming 

 a ledge over the water (diagram Fig. 6 and photograph Fig. 9). 

 Underneath this ledge the ground can be seen to slope down very 

 deeply ; it is possible by means of a strong light to see a f unnel-

shaped crater opening at the deepest part of the lake in which 

 no bottom can be seen. 



The entire crack, with the water which it contains, is located 

 in the Edwards limestone ; but as pointed out above, the structure 

 of the cave would indicate that this crack may extend into the 

 deeper lying strata. 



The distance from the entrance down to the water surface is 

 94 feet, which makes the level of the water about 577 feet. The 

 altitude above sea level of the entrance of the cave was measured 

 merely by means of a barometer, but the figure approaches the 

 altitude of the water surface in Frank Johnson's Well near
