Station K,^,. In the same quarry with this material occurs a pure 

 buff dolomite which breaks with a conchoidal fracture and resembles 

 in all respects the pure dolomite of the reefs at Chazy and Valcour 

 Island. The lense structure of the reef is well exhibited in this quarry 

 but there seems to be only a limited amount of the dolomite exposed.

Station K,^.^. On the road from Cooperville Station to King's Bay, 

 and about a tjuarter of a mile east of the station, is a huge boulder of 

 limestone breccia, which contains angular limestone fragments which 

 are full of fossils. This block of breccia is evidently an erratic, the 

 layers on the opposite side of the road, and on which it seems to rest, 

 being a hard, coarse-grained limestone in even layers, containing 

 Heheriella exfoliata and Zygospira aciitirostris. 



The breccia contains fragments of limestone of various sorts, and 

 the paste has furnished no satisfactory fossils, so the age of the boulder 

 can not be determined. One of the fragments furnished Rafinesquina 

 altcrnafa and a fossil which appeared to be Triplecia extans, and may 

 be of Black River or Trenton age. The largest pebbles are of Chazy 

 age and contain the following fossils, which are sufficiently char- 

 acteristic : 



Bolboporifcs ainerieanus c, Clionvchia nion/realensis r, 



Blasfoidocriniis careharic^dens r, RapJiistoina striatum c, 



Monotrypella sp. c, Isotelns Jiarrisi r, 



Hebertella vnlgaris c, Illanns globosns c. 



The species in this fauna indicate about the horizon of E^^ of the 

 section at Chazy. This boulder was probably brought from the 

 northeast during the glacial period, Chazy conglomerates and breccias 

 being known about Phillipsburg and Mystic, Canada. These con- 

 glomerates are reported by Ells'"' as containing Chazy fossils in the 

 paste and lieekmantown fossils in the pebbles.
