When on my way in June last to visit the newly-discovered 

 copper and gold deposits at Mount Cannindali on the Cannindah 

 Rvin in the Burnett District, I was delayed a day on account of 

 rain at the Head Station. 



In the Station yard I noticed some blocks of limestone 

 lying about, which had been used in the construction of old 

 outbuildings, and in which there were impressions of crinoidal 

 stems. 



On inquiry I was pointed out the place, not many hundred 

 yards west of the Station house, from which this limestone had 

 been obtained, and I at once started out in search of it in the 

 hope of coming across some fossiliferous remains ; but with the 

 exception of finding a few crinoidal stems, and some badly 

 preserved, and Brachiopoda in the limestone and shales, I was 

 unsuccessful. There was, however, no difficulty in recognising 

 the beds as part of the Gympie Series, the lowest member of the 

 Permo-carboniferous System, as developed in Queensland. 



1 was fortunate enough to come across a very interesting 

 section of these rocks, in which a very slightly altered olivine 

 basalt occurs interbedded. 



The rocks in question have a general strike of north-north- 

 west and north-north-east, and they dip east-north-east at an 

 angle of 50 degrees from the horizontal.
