There is great need for systematic exploration and surveying, as the existing 

 plan of the ' new ' cave has been found inaccurate and misleading, and practically 

 nothing is known of the ' old ' cave. Geologically the ' new ' cave is of great 

 antiquity, as evinced by the enormous size and number of the stalactite and 

 stalagmite formations. There is no evidence of present active water-action, the 

 cave being practically dry, except at two points erroneously called ' the River.' 

 The explored passages are estimated at a mile and a quarter in length.
