SCIENTIFIC SUKVEY. * 231 



granite is not beautiful, and the constituents are coarse. My im- 

 pression is that this granite extends a greater distance than is 

 represented, or into the valley of St. George river towards the vil- 

 lage of Warren. 



Another limited patch is exhibited in the north-west part of 

 Hope, and its stratigraphical relations appear in Fig. 35. We noticed 

 it upon the road crossing Muddy mountain. It is a coarse variety, 

 generally possessing inferior economical qualities. It appears to 

 be an immense bed in gneissic strata. 



The last development of granite to be noticed lies mostly in 

 Camden, forming the base of Megunticook mountain. Part of it 

 occurs on the west side of Lincolnville or Canaan pond, part lies 

 on the promontory running into the pond, but the greatest portion 

 is about the mountain in Camden. It is a beautifully white vari- 

 ety, extensively quarried from the large fragments that have fallen 

 down the steep side of the mountain. A portion of it is repre- 

 sented in a section in Fig. 35, where it seems to form a synclinal 

 axis with the granite of Muddy mountain. The precise extent of 

 this granite into Megunticook mountain is unknown to us, as we 

 had not time to ascend it. It is a fact worthy of remembrance 

 that the granite of Knox county is disposed to arrange itself into 

 mountains and mountain ranges. The scenery about Megunticook 

 mountain is quite wild and interesting. 



The gneiss, (mica schist often,) of Lincolnville and Northport, 

 contains many beds of granite. One of them near the Witherby 

 House in Northport, is a beautiful variety of tabular granite, and 

 is comparatively quite large. As we explored these towns very 

 little, larger masses of granite may exist there, which escaped our 

 notice. 



2. Gneiss and Mica Schist. 



The greater portion of the rocks of the region now being described 

 are obscure gneiss and mica schist. So much of the schist prevails 

 that it is difficult to avoid calling the whole deposit by that name. 

 The micaceous rocks which are evidently connected with the Ta- 

 conic series are excluded from this designation. It is doubtless 

 the case that in our anxiety not to detract from the limits of 

 the Taconic series, we have included some of the older mica 

 schists among them. It cannot be doubted that the strata described 

 under this head are older than the Taconic rocks, whatever age 

 may be assigned to the latter.
