Geology 



wear off some of the stiffness and to get our blood into 

 circulation, we once more started on our voyage of 

 discovery. Arrived at the top of the cliff, we first 

 examined our ladder to see that all was secure, and then 

 commenced the descent. At a depth of 80 feet below 

 the entrance to the Creep, we reached the floor of the 

 second chamber, and found a stream of water flowing 

 through its centre, This stream appeared to be of 

 about the same volume as the one which entered the 

 lake in the main chamber by way of the canal. Sus- 

 pecting that the Creep had led us into a higher part of 

 the main system of caves, but unable to make more than 

 a rough estimate of distance owing to the winding 

 nature of the passages, we sent two back to the main 

 chamber with instructions to take the canoe up the canal 

 as far as the barrier and there to show a light, in case 

 we might be able to see it from the mouth of the tunnel 

 into which the stream flowed. In the meantime we 

 continued our exploration and found that the stream 

 issued from a low tunnel on the north side of the 

 chamber. This tunnel we were able to follow as the 

 water did not cover the whole width of the floor, and 

 where it did extend to the foot of the wall was shallow 

 enough to permit of our wading. 



Shortly the tunnel widened considerably and at the 

 same time became much lower, so that much stooping 

 was necessary. The cross section of this portion of the 

 cave was as in Fig. 26, and the stream meandered from 

 side to side on the broad floor. 



Here the stream had found its way along one of the 

 bedding planes of the limestone, which it had slowly 

 widened by solution, forming a broad low cave. On
