A. Discon£ormity(?) in the Beekmantown beds in old quarry on Raquette 

 river, west of Yaleville one mile north of Norwood (Waddington quad- 

 rangle). The locality where Winchell and Schuchert collected. (Looking 

 northeasterly) 



See page 38. 



B. Perspective view of same ledge. The beds above and below this break 

 appear to be alike, supposedly Ogdensburg ; but unless those below are 

 actually Bucks Bridge, or some new member, this may be a " pseudo- 

 disconformity."
