 to the south on the face of the ridge. This company did not produce 

 any graphite last year, but was engaged in development work. 

 There is considerable ore in sight. 



Pope Mills Graphite Co. This concern located near Pope Mills, 

 St Lawrence county, reported a small production of both crystalline 

 and amorphous graphite. The graphite bearing stratum here carries 

 amounts ranging about 25 per cent, much of which is amorphous 

 in character. Evidently the metamorphic agencies were less pro-

Bly property. This property is situated in the township of 

 Ticonderoga on the northern slopes of Bear Pond mountain and 

 presents some rather promising features. The writer believes that 

 the ore on this property is a stratum higher up in the geological scale 

 than the graphite bed displayed at the other properties in the eastern 

 Adirondacks. The Bly ore is a feldspar-quartz-biotite-graphite 

 schist. The beds have been isoclinally folded so that the outcrop
