240 OCCUKKEXCK OF TIN IN NOVA SCOTIA. PIERS. 



that have offered any chance of becoming commercial producer* 

 of tin. In Carolina the ore mostly occurs in pegmatite dikes, 

 etc., in a wide area of schist (probably of Cambrian age)^ 

 (M)rdered by granite on one side and gneiss (probably Archaean) 

 on the other.* 



Previous occurrences in Nova Scotia. — In tracing the 

 reported finds of tin in Nova Sootia, we learn that some time 

 pievious to IS 69, W. Barnes is said to have discovered tin in a 

 gianitic sand, composed of grains of quartz and feldspar, at 

 Tangier, Halifax county; and John Campbell is said to have 

 found it at Shelburne.f Dr. E. Gilpin also obtained it in 

 pamiing gold at Tangier. It has likewise been reported from 

 Country harbor, Guysborough county.:}: I have also been 

 informed on good authority (Dr. E. Gilpin) that it was found 

 in a granite boulder near Rawdon, Hants county. All of these 

 finds were in connection with drift material derived from 

 granite areas, none of which was traced to its original source. 



I may say that since the discovery at Lake Ramsay, now to 

 be described, tin has been reported to me as found in small 

 quantity and determined by test at two other localities in Nova 

 Scotia, but at present I am not at liberty to give further- 

 information thereof. 



Tin at Lake Ramsay. — For some years past, two or three 

 persons have been employed in prospecting for tin in Nova 

 Scotia, and from time to time suspected samples have been 

 brought to the Provincial Museum, whi^h mostly proved to be 

 sphalerite or zinc-blend, or tourmaline. One of these prospec- 

 tors who has been longest in the field, is Charles Keddy, of Lake 

 Ramsay, to whom further reference will soon be made. 



During the summer of 1906, pieces of quartz crystal were- 

 discovered on the surface of John Reeves's land, in woodland 

 a few hundred yards south-westward of his house, and about
