3f. Blue crystalline limestone-many fossils,shaly partings, crinkly and discontinuous. 7 ft. 4 in. 3g. Thick bedded, calcareous shale, bluish where fresh 7 ft. 3 in. buff to yellow on weathered faces. Beds 3d-3g are probably equivalent to the Salina waterline or Lower Cement bed of the Rosendale district. 4. Cobbleskill limestone. 10 ft. 4a.
