Northern Queensland. 57 



the means of supplementing my own personal labours in other 

 parts of the Colonies, and completing to a certain moderate ex- 

 tent my researches, investigations, and speculations on experi- 

 mental grounds, over many not inconsiderable areas of a region 

 (including those parts of Tasmania which have fallen under review) 

 which is represented by twenty-eight degrees of latitude and 

 fifteen degrees of longitude. Upon the most important portions 

 of this vast territory, either by individual occupation in the field 

 or by aid of the evidence of friends who are engaged in similar 

 studies, I have now been enabled to complete the outlines of a 

 general sketch of the Greology of nearly all Eastern Australia, 

 and of pointing out or illustrating the chief of those Auriferous 

 and other Metalliferous districts which Providence has scattered 

 over the length and breadth af the Australian Continent, as in- 

 centives for the fulfilment of the command to "replenish the 

 earth and subdue it." In the present essay, the chief practical 

 value as relates to the Cape Eiver Gold-field, is due to the 

 careful researches of Mr. Daintree; but there has been left to 

 me the duty of bringing his researches, and those of other field- 

 investigators, into public notice in a connected form. 



And even if our expectations be found, hereafter, of less real 

 importance than has been assigned to them, the matter now con- 

 densed into a brief discussion, such as the present, is not without 

 results of another kind. 



P.S. It may be proper to record here, that the preceding paper 

 has led to very important results, inasmuch as, it having attracted 

 the attention of the Parliament and Government of Queensland, 

 a correspondence with the author ensued, and on his recom- 

 mendation, the colony has been divided into two districts, of 

 which the southern has been placed in the charge of Mr. Aplin, 

 and the northern has been allotted to Mr. Daintree. In due 

 time, it is hoped the whole will be surveyed and described.
