278 ON THE GEOLOGY AND 



endowed this spot with a most bountiful supply of 

 ore, but she has enriched it with the materials re- 

 quired to turn it to the best advantage. She has sup- 

 plied it with fluxes, fuel, water-powers, and all that 

 could facilitate the working of these mines to any ex- 

 tent that might be wished. After a careful and at- 

 tentive examination of this spot, and of the metallic 

 deposits which it presents, we have no hesitation in 

 stating it as our firm conviction, that as soon as these 

 ores shall be made the object of operations, conduct- 

 ed on improved and scientific principles, they will 

 immediately yield to their owners the most ample re- 

 muneration. 



To the mineralogist Franklin affords not less in- 

 terest. It has already furnished three new minerals, 

 which have not as yet been met with elsewhere ; the 

 red zinc ore, the Franklinite and the Jeffersonite. 

 The sequel of this paper will show that to this num- 

 ber one more is to be added, and that the whole num- 

 ber of minerals, which are met with here, amounts 

 to about thirty, among which eight or ten present 

 new varieties. 



The geological features of this country are not less 

 interesting, for it will be found from subsequent de- 

 tails, that it contains large beds of ore in a rock 

 which is seldom very metalliferous ; and that it pre- 

 sents us a spot, where formations of different ages 

 may be observed in contact, and their mode of super- 

 position determined with ease. 



The attentive observer of the Franklin minerals 

 will, we think, readily perceive that they present
