western base, in the town of Berlin, 1ST. Y. The schists of the 

 range dip to the eastward, have a greenish color, feel talcose 

 to the touch, and appear unlike the dark shales of the Hudson 

 Terrane. Continuing on over the range and down the western 

 slope, I found that the schistose character of the rock was 

 gradually disappearing and that it was becoming more shaly. 

 The greenish color continued, but, toward the western base 

 of the range, a mile north of the village of Berlin, the color 

 began to change, the green and dark shales appearing in the 

 same stratum, and even in hand specimens, and soon the dark 

 shale of the Hudson Terrane was the prevailing rock. A 

 little lower down, the characteristic brown sandstones of the 

 Hudson Terrane began to appear in the shales ; and, just east 

 of Berlin village, the limestones appeared from beneath the 

 shales. In other words, it is a repetition of the Gray lock and 

 Mt. Anthony sections with the exception of less alteration in 

 the lower part of the shales, and in the limestones. One mile 

 south of South Berlin "post office, on the eastern side of the 

 valley, the limestones dip to the east and northeast. At the 

 base of the section there is a considerable thickness of dark 

 argillaceous shale, upon which the limestone rests conformably. 

 Continuing up the west slope of the mountain, more or less 

 impure limestones are met with in which I found Solenojpora 

 comjpacta, plates of crinoidal columns, Mxirchisonia gracilis f 

 (fig. 7), and fragments of indeterminable gasteropods. The

fossil-bearing limestone is subjacent to, and interbedded with, 

 shales that are succeeded by arenaceous limestones which, in 

 turn, are conformably subjacent to the shales and schists of the 

 Taconic range. 



The next locality examined was one described by Dr. Em- 

 mons as showing fossiliferous limestones of the Champlain 

 series, resting unconformably upon the " Taconic " schists (Am.
