present year be progressively maintained, the industry 

 bids fair to be a powerful lever in the opening up of the 

 interior of the country. 



The search for gold has also brought to light the fa6t 

 that diamonds are to be found in the colony ; and a 

 sample of one of these, forwarded to Europe by Mr. 

 GEORGE GARNETT to be cut and polished, was pronounced 

 to be of good " water," though, being of small size, 

 practically valueless. Still the fa6t of the occurrence of 

 these precious stones in the colony, is interesting and 

 suggestive. 



Another mineral to be added to the colony list, is 

 Catlinite, a variety of pipe-stone, specimens of which 

 were obtained by Mr. IM THURN from the Indians of 

 Konkarno. This mineral is composed chiefly of a 

 mixture of hydrated silicates of aluminium, magnesium, 

 lime, iron, and manganese. 



The knowledge that we at present have of the rocks 

 and minerals of the colony, must be regarded as but the 

 firstfruits of research, for the gradual development of the 

 country, with its detailed surveys of the vast forests and 

 savannahs, now lying useless and unexplored, cannot 

 but be the means of considerably extending it. — Ed.
