Art. XXYII. — T/ie Camhrian Conglomerate of Rijpton in 

 Vermont; by T. Nelson Dalk.* 



Hitchcock and Hagerf represented a sti'ip of " talcose 

 conglomerate" as beginning a little south of the village of 

 Ripton in Addison Co. and widening northwards in the town- 

 ship of Lincoln, attaining its greatest width, 6 1/2 miles, in 

 Chittenden Co., and extending to the Canada line. 



In Ripton it appears as bordered on the east by the granites 

 and gneisses which form the axis of the Grreen Mountain range 

 and on the west by tlie qnartzite and schist which underlie the 

 marble and dolomite of the Yernaont Valley.
