In the fifth volume of the same Journal, it is stated that upon a 

 further examination of these specimens, they are satisfied they are 

 not fossils. This locality is at least fifty miles distant from the 

 new locality described by Mr. Mason. We mention this that no 

 one may confound the two. This new locality is probably the 

 prolongation into New Hampshire of the Oriskany sandstone belt 

 of Maine. Many of its strata are clay slates, such as are described 

 as occupying the whole of the Megalloway above Wilson's Mills, 

 and such as have been shown us from the Kennebago valley further 

 east. And in the final report upon the Geology of New Hamp- 

 shire, an account is given by Prof. J. D. Whitney, (now State 

 Geologist of California, ) of a clay slate region in the very northern 

 portion of the State — See final Rept. Geol. N. R., joage 6S. This 

 rock does not extend beyond New Hampshire into Vermont, un- 

 less in a very unaltered state, as along the whole of the north-east 

 part of Vermont the rocks are granite and mica schist. 



II. Notes upon the Geology of Moosehead Lake. 



We had an opportunity of visiting this lake in the early part of 

 the season, but not of exploring it. We visited one or two locali- 

 ties there, and give our impressions in general respecting the 

 geology of the whole lake. We found Mr. Houghton's observa- 

 tions correct, which he described in the Preliminary Report. Our 

 remarks are designed to be supplementary to his repox't. 



The rock at the south end of the lake is clay slate, part of the 

 great belt described previously. At Greenville the dip is rather 

 north-westerly. Immediately succediug the clay slate is a narrow 

 band of syenite, a rock entirely distinct from the common granitic 

 rocks of the vicinity. It is our impression that the clay slate dips 

 south-easterly immediately adjacent to this syenite. This syenite 

 belt cannot be over two miles in width. At the base of Squaw 

 mountain, an immense range on the south-west side, the rock is 

 mica schist dipping 60° south-easterly. Half way between the 

 mountain and shore the syenite appears again, being on the south 

 side of the schist. 



Fully half the length of the lake is occupied by this mica schist, 



• a rock supposed to be fossiliferous, as the Favosiles Golhlandica (?) 



has been found in it at the base of Squaw mountain. The dip of 



the strata is very high to the north. At Mount Kineo we come to a 



narrow band of siliceous slate. A mountain upon the west side
