From Lynx 3/5 mi W then N to humer, Oletrangy = 22 ft greenish shale. Oletrangy - West Min on North at at about 845. Gastropods in very hard white limestone. Buzz and Rust Rock road from Brink creek side, Lowest West Min seen actually was 110 ft above humer, 760+110= 870 ft. Highest Catbschard seen actually at sharp bend in road = about 810 ft. One end not between the Brink Rock & West Min probably is near 820 I think. From Wrightsville top of hill at 989cm. Here West Min = 125 ft thick up to this corner. One mile east of this 989 cm, at hill E of 954 the West Min is exposed up to 960, 3/4 mi SE of 954 the Hills hor ss is exposed at 960. SE of 925, Hills hor ss is seen at 970. 3/4 mi S E of 954 the furze hill ridge forming top of West Min is seen at 970 about. The next full E end aims Black Slate at 980 NW of Nashim School, 101 West Min in, east bed of turn, SE by minumment at corner 981, top of highest exposure of West Min = 987 exact, and no stratum above this line, or abundant fossils, but Chas. Space. Rock is highly mineralized in some layers directly S and SW of min- ument in open fields, at about 960 to 970, with Schmidtelle, Brachyura, Ostia reticularis, Septaria, Dolomiale, Dolomite, Calymere, Spirifer with radiate striations and fairly stiff folds, paddle shaped spines of? Ormond Leda. I don't know to what genus they belong. Also the spirifer with moderate fold g small size figured from West Min bed. Correlates with our all species, Oligodonta to Emmata. Base of West Min at least as low as 920. This gives a minimum thickness of 987 - 920 = 67 ft. One hp locality is 1/2 mile east of latter locality, making allowance for eastward dip the maximum thickness of West Min at West Min in is 67 + 8 = 75 ft. Could not be over 82 ft.
