The ledges of feldspar are numerous and one of them 

 has a cave large enough for a person to move around in com- 

 fortably. It is within a short distance of Casco Village. 

 About two miles from this one there is another cave, which, 

 as far as I can learn, no woman has ever entered until re- 

 cently. It has a narrow opening and a very steep ascent. 

 After entering I found a nice little room lined with pink 

 feldspar. Light came in through two small apertures. The 

 interior is at least ten feet long, four feet wide and from 

 three to five feet high. I could easily stand upright in one 

 place. The opening to the cave is concealed from casual 

 view by trees and bushes. Near here is the Devil's Stairway 

 and the Devil's Fire-place, the cave itself being called "The 

 Devils Den." There is another cave by tJie same name near 

 Webb's Mills. I know a place where white quartz crystals 

 are hanging in clusters, but the owner as yet has been too 

 stubborn to be approached. 



The bill drawn up a few years ago in regard to forcing 

 the opening of mines and giving the discoverer a certain 

 percent, should be put into effect. 



I will sum up my "finds" in Casco, and within a radius 

 of ten miles, as follows: Iron pyrites, blue beryls, lavender 

 beryls, rose quartz, silver, pearls, brown, black, and dark 

 brown tourmalines, cinnamon garnets, iron cubes, ironore, 

 inferior garnets, jasper crystals, white quartz crystals, pink 

 feldspar, white clevelandite, muscovite, sulphur, yellow 

 ochre and several kinds of granite. 



Notes for Geological Section 



It is purposed to publish in the Maine Naturalist a list 

 of the minerals found in Maine giving the more important 

 occurrences of each species. It is desired to make this list 

 as complete as possible. Any person who has a local list of 

 minerals is requested to send a copy to the editor of this 

 department. Edward H. Perkins, Box 52, Waterville, Maine.
