but (probably from there being only one specimen of our fine bituminous 

 looking coal) he has not analysed it ; and it is a curious comment on 

 the importance of the old collections, and those from distant countries, 

 that at the distance of nearly a quarter of a century they should afford 

 us not only this information, but also serve to put us on our guard when 

 we attempt to pronounce on the value of the coal ; for had only our inferior 

 Jet coal been brought to us, we should have pronounced it as nearly 

 worthless, which it is as a steam coal. Mr. Prinsep's jet coal will no 

 doubt be found in time. Ours is probably a mere surface shale, though 

 I can detect no organic remains. 



The value of a really good steam coal, not only in Ava, but for all our 

 sea-going steamers, whether public or private, I need not further remark 

 upon.
