Geology 



soup which one of our ever-thoughtful navy men had 

 prepared for us. 



Fortified by the nourishing contents of the flask, the 

 ascent was commenced, and an extremely arduous under- 

 taking it proved. The last man, after first securing the 

 ladder to his waist-belt, had to cut the connections with 

 the boulder, so that it might be possible to haul up the 

 ladders on arrival at the surface. The ropes had shrunk 

 somewhat owing to the fact that they had been hanging 

 so long in the water, and on cutting the ties he was 

 immediately lifted off his feet and carried several feet 

 upwards, the ladder meanwhile swinging violently from 

 side to side. Having secured a foothold on the ladder 

 and unfastened the connection with his belt, he eventually 

 reached the surface in safety. 



The ladders were hauled up, and a quantity of 

 fluorescein was put into the stream so that it might 

 make its way underground during the night. The next 

 evening saw us back at our main camp, and another 

 period of waiting followed, during which a keen look-out 

 was kept upon the springs. 



On the third morning the water of our swimming 

 pool was seen to be faintly coloured though the tint 

 could not be detected in the shallower parts of the stream, 

 but during the day the fluorescein came down in full 

 force, thus proving the connection between Funnel Sink 

 and the main cave. Thus the flow of water from Funnel 

 Sink was seen to be parallel to that from Lake Sink to 

 East Burn, both flowing in a direction 10 west of south. 



The weather now changed completely, heavy rains 

 falling almost every day, and the streams became swollen 

 to such an extent as to render navigation very hazardous.
