Report of the State Geologist. 



New Berlin. 



New Berlin township is directly south of Columbus, its eastern boundary 

 being the Unadilla river, its western Norwich and North Norwich, while 

 Sherburne forms a part of its northern boundary. West brook rises in the 

 southern part of Columbus and flows southeasterly across the northeastern 

 part of New Berlin and through New Berlin village into the Unadilla river. 

 In the southwestern corner of Columbus, to the northwest of the head of 

 West brook, is the high divide which runs north and south along the Sher- 

 burne-Columbus township line and for some distance south into New Berlin. 

 On top of this divide in the southwestern part of Columbus, are the rocks 

 (XIX C 4 ) which were referred to the Ithaca formation when describing the 

 exposures along "Nigger brook" in Sherburne township. 1 



XX A 1 . Commencing about one-half of a mile east of XIX C 4 , are 

 exposures of rocks, and at intervals there are small outcrops for one and one- 

 half miles along the highway to the southeast when the upper part of West 

 brook is reached. Along the brook there are plenty of exposures from near 

 its head to New Berlin village. The exposure A 1 consists of arenaceous shales 

 by the side of the highway nearly five miles northwest of New Berlin village. 

 This outcrop is 670 feet higher than the New Berlin railroad station, or 

 approximately 1,758 feet A. T. 2 Only a few minutes were spent in collecting 

 fossils, but a number of species were obtained, among which occurs Spirifer 

 mesastrialis, H. The fauna and stratigraphic position of the layer show it 

 to be in the Ithaca formation. Below is the complete list of fossils : 



1. Spirifer mucronatus (Con.), Bill., var. poster us, H. and C. (c) 



One of these specimens is quite like the form of S. mesacostai lis 

 H. (as figure 10 plate 40, Palaeontolgy of New York, Vol. IV.). 



2. Spirifer mesastrialis, Hall. (rr) 



3. Ohonetes scitula, Hall. (c) 



4. lihynchonella (Camarotcechid) eximia, Hall if). (rr) 



5. Idorhynchus mesacostaUs, Hall. (it) 



6. Atrypa reticularis (Linne), Dalm. (rr) 



7. Stropheodonta demissa (Con.), Hall. (rr) 



8. Actinopteria, sp. (rr) 



9. Grammy sia cf. dliptica, Hall. (rr) 



XX A 5 . About three-fourths of a mile southeast of the locality just 

 described, near the head of West brook and 180 feet lower, fossiliferous are- 

 naceous shales occur by the roadside and the following species were collected :
