Riley's Will Isaac, 1/4 mile NW of Riley. Farm east with Strph, mays, Villensis NE 1/4 close along west bank of small stream. 33 feet below Devon limestones expands near Riley station, = immediately north of station. Dip strongly southward hence this part of Farm unit is pro- fably at least 66 ft below Dev. on an if not more. Immediately below Devonium is dense blue clay limestone as south east of Givens station, up the road from the bridge. Near Cave 1 mi W of Riley Braspora fauna in nodular lines at me in clay rock, like mudsols at many Rilm end at SE of Columbus. Here at 10 ft below Devon l. Columbana albedata occurs 5 ft lower than Braspora level but not more. Devonian l. along road may sink SW of cave = at least 6 1/2 ft thick. Farther south again a Columnaria was found close above here in 33 black shale. Hence doubt contacts. The strong south dip carries the Black shale below the road going east as far as beyond the first house which is on next side of road, 1 mi. from RR. Streptolasma just below Devon l. canadianum, Canadianes. 11 ft below black shale farther down week in top of Columnaria albedata! Layers 2 ft thick. Columnaria abundant, evidently the source of more specimens. Streptolasma canadensis shrunken- away below Columnaria level, in fossil- iferous strata 3 ft thick, squeezed as since amount of southward dip is not known anyway. Then Tetradium and Calapsecia Streptolasma canadensis + Columnaria halbii generally above albedata but this not certain in layers at least 2 ft thick. The Tetradium in layer 1 ft thick by large specimens 2 ft across, 100 yds further S is shrunk at south branch. Dip of rock is gently southward, Not express then for 1/3 mile when rocks lie way gently northward, here is Zander Madison clay rock. 50 ft exact measurement above point where hand enters from west is Colum- naria bed top. By turned SW up hill. Follow well Rt Milltown Valley View.
