 Rocklands Station, who has a very deep interest in the 

 scientific and economical development of the Tableland,

 the Happy Creek, sends a great part of its waters to the sub- 

 terranean basin through a sinkhole. The " Karren phae- 

 nomen " is only in its beginning — everywhere on the out- 

 cropping rocks.
