in the name of the 

 group to Eolian Lime- 

 stone, and we adopt it 

 here. The name is de- 

 rived from Mount Eolus 

 in Dorset, Vt. Emmons 

 applied the name Stock- 

 bridge Limestone to 

 the limestones in Thom- 

 aston and Camden twen- 

 ty years ago. There 

 are three large belts of 

 Eolian limestone in this 

 region of country to be 

 described—and, indeed, 

 we know of no others 

 in the whole State. The 

 largest extends from 

 the State's Prison in 

 Thomaston nearly 

 Chickawakie pond 

 Camden. Another 

 in Rockland. A third 

 is in Camden. Besides 

 these, in Thomaston 

 and South Thomaston 

 are several large and 

 small beds of limestone 

 and dolomite in the 

 schists.

We present here four 

 sections, (Figs. 37, 38, 

 39 and 40,) crossing all 

 the limestone belts and beds in Thomaston 

 and Rockland. They will give the rela- 

 tions of the different rocks to one another 

 much better than detailed descriptions. 



These sections are very important, as they 

 show the relations of all the beds of lime- 

 stone in Rockland, Thomaston and South 

 Thomaston, to all the rocks in the vicinity. 

 They are all drawn parallel to one another,
