Notwithstanding the prodigious extent of igneous action to 

 which the limestone has been evidently exposed in these belts, 

 manifested by the width of the space over which a total modi- 

 fication of the rock has been effected, we still discern a very 

 distinct stratification, the beds dipping steeply towards the south- 

 east. 



In the same line with this series, and about one mile and a half 

 further to the southwest, occurs another somewhat shorter belt of 

 the altered limestone, a little beyond Lion Pond. The length 

 throughout which the limestone has been modified, does not 

 exceed two hundred or three hundred feet, and the width of the 

 belt is not considerable. The locality is nevertheless an in- 

 teresting one, for we find well exposed, within a tract not more 

 than a fourth of a mile wide, first, the primary strata on the 

 southeast, then the sandstone, F. I., next the blue limestone, F. 

 II. passing into the sandstone, and assuming near the passage 

 a clear reddish hue, and lastly, the belt of altered limestone in 

 contact with a small elevated hill or dike of felspathic sienite, 

 the cause of the altered structure of the calcareous rock. All of 

 these stratified masses, the gneiss, the sandstone, the blue limestone, 

 and the white crystalline belt, dip alike towards the northwest at 

 a gentle inclination. 



Graphite is here present as usual in the calcareous mass ; 

 which besides contains other minerals. 



Portions of the altered rock are coarsely crystalline, though 

 other parts of it are more minutely granular. A variety which 

 is variegated with numerous blue shades of plumbaginous mineral, 

 might evidently, from its susceptibility of a good polish, be em- 

 ployed as an ornamental marble. 



Between the sienitic ridge here spoken of and another lying a 

 short distance to the north, there occurs another smaller belt of 

 the altered limestone, deeply buried between the primary rocks. 

 At this spot some enthusiast in search of mineral treasures, 

 expended at a former day no inconsiderable amount of time and 

 labour, in excavations for silver ore in the sparry limestone. 



West of the last mentioned point may be seen, by the side of 

 Panther Pond, another still more unimportant exhibition of the 

 altered sparry rock, not deserving of a special description.
