26 SINCLAIR ON PISCICULTURE. 



in every light. Viewing the Bermudas as formerly a portion of the 

 American Continent, let us consider whether there be sufficient 

 ground on which to base our supposition. The Islands are formed, 

 as I have before stated, of sandstone composed of comminuted shell 

 and coral; but the particular stone which I have instanced as forming 

 part of the southern shore, is so compact as to have the appearance 

 of solid sandstone, or, indeed, I may say limestone. Now if we are to 

 identify the Islands as forming part of that main land which juts 

 out in their direction, we must first ascertain if that extension of the 

 main be of similar formation. Speaking to Mr. Hill, the obliging 

 mate of the E.. M. S. "Delta," on my return from the Islands in 

 1860, I found that he was well acquainted with the American coast; 

 aiid upon enquiry he informed me that the geological character of 

 Cape Hatteras was decidedly a white sandstone or limestone, very 

 similar in appearance to Bermuda stone. 



I am sorry I have no specimen of the Hatteras stone, to com- 

 pare Avith that of Bermuda, and I also regret that I have not had 

 an opportunity of consulting any work upon the geology of that 

 locality, whereby I could clearly ascertain the real nature of its 

 structure. However, as I merely mention the connection of the 

 Bermuda group with the main as a probability, and nothing more, 

 and as my views are decidedly in favour of volcanic origin, Ave may 

 leave the consideration of the question for futui-e investigation, as I 

 beg to do other subjects connected with the geology of the Bermu- 

 das, Avhich, I hope, if life and health be spared me, to treat of in 

 another paper.
