made at Brown's Falls, Chittenango Springs, at Waterville and 

 Oriskany Falls, show that" etc. etc. Still later Hartnagel* in 

 describing the section at Litchfield, Herkimer Co., says : ''The 

 upper portion of the Manlius becomes complicated with Coey- 

 mans limestone, the faunas of these two formations either 

 mingling or alternately recurring." 



Our observations in the vicinity of Oriskany Falls have been 

 mainly confined to the quarries and fields to the north of the 

 town. One may reach these fine collecting grounds by following 

 the old Chenango canal northward for nearly a mile and then pas- 

 sing up and westward through field and quarries ; or he may 

 take the road to the west of the canal. This forks about Y\ of a 

 mile out. One road then leads to Utica in a north-easterly di- 

 rection, while the other continues northward over the hills. 

 Near the forks of the road and then along either branch fine ex- 

 posures are found. The lower road about a mile out from town, 

 passes over a little sluice near an old lime-kiln in the woods to 

 the left. The old quarry nearby shows bluish-drab layers of im- 

 pure limestone. Fossils are rare except Leperditia ; but Mr. 

 Pacheco of our party succeeded in finding recognizable fragments 

 of Euryptertis . and so we have indicated the position of this bed 

 in our general seetion No. 5, Plate I, by the word Eurypterus. 

 A small outcropping of limestone layers by the roadside not far 

 south of the sluice before mentioned yields a considerable number 

 of small gasteropods, but their identification is difficult. They 

 are presumably stratigraphically below the Eurypterus bearing 

 horizon. 



Near the lower, or Utica, road small outcrops may be seen in 

 the fields, and, if examined they are sure to yield Spirifer vanux- 

 emi in comparative abundance. Outcrops in the bank of the 

 old canal show the same fauna. Eeperditia too is very abundant. 



The layer marked "gasteropod bed" is seen at the big spring 

 from which the water issues that flows under the aforementioned 

 sluice. In the pasture to the south, fragments of this fossilifer- 

 ous layer are found quite frequently as loose boulders or rock 

 fragments. Just beneath it are buff-colored, even-bedded 

 cement-rock layers.
