Prossek — Hamilton and Chemung Series. 



through, the elevated tract of land which follows the eastern side of the 

 Chenango river for some miles. Locally, the narrow pari of this valley is 

 known as "Nigger Hollow." Up this valley, one and one-quarter miles from 

 the river road and in a straight line about two and one-half miles southeast of 

 Sherburne village, is the Lee quarry which was formerly worked for a blue 

 sandstone at its bottom, and above this are blue argillaceous shales contain- 

 ing abundant Hamilton fossils. This quarry is undoubtedly in the upper 

 part of the Hamilton formation as may be inferred from the accompanying 

 list of fossils from the blue shales on top of the sandstone: 

 L. Spvrifw mucronatus (Con.), Bill. (c) 

 Normal Hamilton type. 



2. Spwifer Thllws, Hall. (rr) 



3. LiorJiynchus multicosta, Hall. (c) 



Some of the small specimens show scarcely any plications on the 

 sides of the shell, yet they are nearer in general appearance to this 

 species than to L. mesaoostaUs, H.

This quarry is barometrically lf>N feet above the railroad at Sherburne. 

 The Hamilton shales continue at least forty-five feet higher than at the Lee 

 quarry, as may be seen in an outcrop of fine shales having the characteristic 

 lithologic appearance and fossils, by the side <>f the road that crosses Xigger 

 brook just below the forks. This outcrop is 203 feet above the railroad and 

 has an approximate altitude of 1,245 feet A. T., and the rocks are near the 

 top of the Hamilton formation as the description of those overlying w ill indi- 

 cate. The locality is one and four-tenths miles due south of the Sw an quarry 

 which is regarded as near the top of the Hamilton formation on the northern
