fragment of granite imbedded. Fig. 5. A farmer of the vicinity- 

 stated, that there are several other dikes cutting the hill in simi- 

 lar directions, and this statement derives confirmation from the 

 numerous boulders, or fragments of trap, scattered over the fields 

 and laid up in the farm walls.

Blende and Galena. 



Three miles south of Eaton is a mine wrought for lead. The 

 ore is a mixture of yellowisli brown blende and galena, which 

 is abundant, and was formerly worked in a shaft fifty feet deep, 

 with a horizontal drift, and as I understand with profit. Opera- 

 tions are suspended at present by some legal impediment, and not 

 through a deficiency of the ore. The specimens, with the two 

 sulphurets intermingled, are beautiful, and will reward the min- 

 eralogist for his labor in procuring them. 



Crystallized Smoky Quartz, 



is found near Pendexter's in Bartlett, occupying large geodes in 

 masses of decomposing granite on the flanks of Kearsage moun- 

 tain. The crystals are very clear and beautiful, from one to four 

 inches long, and even one and a half to two inches in diameter. 

 Arsenical pyrites, crystallized and massive, occurs in a large 

 vein, in a mountainous tract, four miles north of Bartlett, belong- 

 ing to Mr. Eastman.
