Figs. 3Y, 38, 39 and 40, show the relations of the Taconic schists 

 to the adjacent formations. If these sections illustrate the natural 

 order of the formations, then we must say at once, that a part of 

 these schists are older, and a part more recent, than the Eolian 

 limestone. We rely upon such cases as the exhibition of the strata 

 in Holmes' and Ingraham's quarries, (Figs. 39 and 40,) to prove 

 the schists in some cases the more recent of the two. And by the 

 supposition of inverted folds, we may regard all the schists as the 

 newest. For example ; in Fig. 37, suppose the dolomite at the 

 Marsh quarry to be the equivalent of the other belt of limestone at 

 the Fulling Mill and Beechwoods quarries. Then the intervening 

 schist is newer than both kinds of limestone, and thie western mass 

 of limestone contains two or three inverted folds. Similar sup- 

 positions can reduce the other sections to the same order. ■ It will 

 be interesting, in this connection, to compare the theoretical order 

 of these formations with the actiial existing order in Camden, as 

 shown in Fig. 41. There. the schists are all above the limestone, 

 except a few that have been disturbed by a fault. 



A little study of the preceding table of dips will show us a few 

 axes besides those figured. An interesting one is situated west 

 of Marsh's mountain, both in Rockland and Thomaston. It ex- 

 tends for a considerable distance — a mile or so we have followed 

 it ; and the crest of the ridge has been worn away while the sides
