THE SECTIOx\ AT SCHOHARIE, N. V. 377 



THE HAMILTON 



The Hamilton is reached on the west side at little more than 

 a mile above Schoharie, while on the east side it caps the hill 

 at about the same distance east from Schoharie. The Marcellus 

 with its Goniatite limestone comes down to the river at Middle- 

 burg, five miles above Schoharie, where the Hamilton sandstones 

 form a bold cliff. The shales contain LiorJiyncJms Ihnitaris in 

 profusion while the limestone is rich in Gouiatitcs, OrtJioccras 

 and Nautilus. The Hamilton sandstones have yielded many 

 species of lamellibranchs. No measurements of these beds were 

 made. 



LOCALITIES FOR COLLECTORS 



The impression prevails that as the Schoharie region has been 

 a collecting ground for three-fourths of a century, it must be 

 practically exhausted ; but this is wholly erroneous. It is quite 

 true that weathered specimens free from the rock are no longer 

 to be had plentifully but the writer discovered that the old lo- 

 calities repay careful work as well as they did thirty years ago, 

 when he first collected there. 



The Coralline limestone is well shown near the African church 

 in Schoharie and fragments of the rock in excellent condition 

 are plentiful in stone fences along the lower road leading north- 

 ward from the village. 



The Tentaculite is fully exposed in the long line of old 

 quarries from the cemetery northward, in all of which the waste 

 piles are very large. The Tentaciilites are in best condition in 

 an old quarry at the south end of the village. 



The Lower Pentamerus cliff is broken at several places be- 

 tween the cemetery and the point where it crosses the Middle- 

 burg road, less than a mile south from Schoharie, and it is 

 quarried extensively just north from the village. The upper 

 layers are shown on the west side in a field barely one-fourth of 

 a mile south from the schoolhouse. 



The Delthyris gives good returns on the road leading to Mr. 

 Brown's house, northeast from the village ; in a watercourse
