to form, this concretion ; for upon tracing this vein^ we found 

 that it gradually and insensibly softens as it recedes from the 

 beach : so that at the distance of thirty yards it assumes the ap- 

 pearance, and is in fact, a limestone sand. 



Calcareous clays are found in James's valley and Friar's valley ; 

 and a calcareous spar, together with small oblong round stones, 

 corresponding witli the description of plaster of Paris, are found 

 in considerable quantity in the hills adjoining Turk's Cap Bay, 

 and Prosperous Bay. Here also has been discovered a variety of 

 pebbles extremely hard, which bear a fine polish, and have been 

 made into seals and ornaments.* 



Calcareous spar is also found in the body of very hard and 

 ponderous stone at Munden's Cove and Sandy Bay ; and even 

 in the interior of the island : and it is said, that on George's 

 Island might be collected a considerable quantity of gypsum. 



The following are the analyses, by the late Doctor Adam 

 Baildon, of the lime quarries already opened. The specimens of 

 plaster of Paris have not yet been analysed. 



* Specimens of all these stones were forwarded to the Honourable the Court of 

 Directors in December 1810.
