frequent approach to the octohedron, the regular crystalline form 

 of this species of iron ore. It is also sometimes of the compact 

 variety. It is considered equal to any in the State for the quality 

 of the iron which it produces. The same vein is said to have 

 been opened still further to the southwest, but the remotest point 

 in that direction to which it may be traced has not been ascer- 

 tained. 



Three varieties of the ore occur at the Succasunny Mine — a 

 blue ore, a reddish ore, and a sparry ore. The first lies next to 

 the foot-wall, the red ore occurring adjacent to the hanging 

 wall, while the sparry ore runs generally in separate veins 

 between the rest of the vein and the hanging wall. One vein of 

 this variety, measuring twenty-two inches in thickness, is divided 

 from the other part of the ore by only about three or four inches 

 of rocky matter. 



The price of the blue and red ores at the mine is $3.50 per ton ; 

 that of the sparry ore, somewhat less rich in iron, is $2.50. The 

 mine is not very actively worked ; about fifteen hundred tons 

 per annum having been mined during the last five years. 



Entering in the next place upon the third or northwestern 

 belt of veins, we commence, towards the northeast, with the 

 unimportant excavations near the old Denmark Forge, which 

 are to be regarded as openings in search of ore rather than a 

 regular mine. The first mine of consequence in this series is the 

 Mount Hope Blue Mine, now no longer wrought, occurring at a 

 distance of nearly four miles to the southwest of the Denmark 

 openings. The vein seems to average from twelve to fourteen 

 feet in thickness. At the surface of the ground the vein was 

 from eighteen to twenty feet thick. It has been worked to a 

 depth of one hundred feet, being, at the deeper portions, as much 

 as twenty-four feet in thickness. 



The excavations consist of a series of inclined galleries, at a 

 slope of about 25°, in descending zigzag arrangement. The ore 

 has been removed throughout a length of several hundred feet. 

 The mine has been abandoned in consequence of the loo rapid 

 accumulation of water. An adit, carried into the mine from near 

 the base of the hill, would seem to be all that is required to give 

 access once more to this large mass of ore. 



The next mine, in our progress to the southwest, is the
