extends from Mudgee to Goulburn. Seven of them possess 

 galleries and chambers of considerable extent, and are remark- 

 able for the variety of form and beauty of their stalactites and 

 stalagmites. An underground river, of some interest, flows 

 through two of them. 



The other two caverns are merely grand arches rising to a 

 height of about 300ft. 



These caves were formerly known as the Binda, or Fish 

 Eiver Caves, and were apparently known to Europeans as 

 early as 1831. 



They are about 111 miles from Sydney, and of easy access. 

 The Government recently proclaimed the district in which 

 they are situated a public reserve, erected necessary buildings, 

 and appointed a curator.
