Peter's Mine, formerly worked, partly in a shaft, partly in a 

 quarry open to the sky. 



At this place the dip, both of the vein and the primary strata 

 bounding it, is at an angle of about 60° to the southeast. The 

 rock above the ore is a mixture of felspar and mica in a state of 

 disintegration; in other places it consists of a fine pinkish felspar 

 rock in the same rotten condition. The form of the vein at the 

 place where it has been worked, is that of a narrow wall of ore, 

 six feet in thickness, which presently swells into a huge mass of 

 an oval form, fifty feet in diameter. This pool of ore has been 

 wrought beneath the open air to a depth of about seventy feet, 

 the water being drained off by an adit cut through the adjoining 

 wall of gneiss. 



This ore is said to yield an iron which is brittle at a red heat, 

 or red short. 



The Spanish Hope and Good Hope mines form the next group 

 of openings as we proceed to the northeast. They occupy the 

 southwestern extremity of a spur of the main mountain, and occur 

 at a distance of not more than one-third of a mile from the New 

 York state line. 



The hill in which these mines lie is very rugged, and the ordi- 

 nary gneiss rock composing it much disturbed, connected with a 

 considerable degree of irregularity in the metalliferous veins. 

 The general width of the main body of ore is about eight feet, 

 dipping with the strata to the southeast at an average inclination 

 of 70°. The most northwestern of these openings, called the 

 Good Hope Mine, exhibits the vein in considerable regularity, 

 dipping at an angle of about 80° to the southeast, and having 

 a pretty uniform width of nearly twelve feet. These mines were 

 somewhat extensively worked by an English company before the 

 revolutionary war: the Good Hope Mine now showing a large 

 excavation, sixty feet in depth. The ore proved of superior qua- 

 lity, which led, about twenty years ago, to a resumption of mining 

 operations, which have been since abandoned. 



In the same prolongation, towards the north-northeast, we 

 find a continuation of this series of mines for several miles into 

 the State of New York, but whether these occur upon the same 

 fine of veins, seems to be not quite established. 



Reviewing in their general connexion the whole line of veins
