PERRY..... WEST-TUBCO 139 Along the highway and to the southwest in 9:1:1, 9:1:4, and 8:5:5 are frequent exposures of the Perry shales and conglomerates. The conglomerate occurs in only one outcrop (outcrop 1) along the road forming the 40-foot knoll in n. 9:1:4. To the west and southwest, the elongate 60-foot knoll in w. central 9:1:4 and the little knoll near the margin are both composed of red shales rising abruptly out of a flat of Pleistocene clay. The red shales eg. in outcrop (outcrop 4) on both sides of the road at the 40-ft. contour on the east edge of 8:5:5, and reappear (outcrop 5) forming the 40-ft. knoll in s.w. 8:5:5. RELATIONS - south of outcrop 1, there occurs a thick diabase dike trending N 65-70 degrees east, and which may be traced westerly for a mile or more into the diabase mass forming the 100-ft. hill in 8:5:8, and also occurring easterly on the road in n.-central 9:1:5. This diabase mass is not immediately associated with the jerry but intrudes some black shales which outcrop between it and the jerry in the barnyard west of the house of Tr.----- in s.e. 9:1:4. These shales probably occupy the depression which may be followed to the east, lying between the trap on the south and the jerry on the north, south of it trap mass occurs some rhoyolite. This is gray in color where it outcrops in the road south of the creek on the east edge of 9:1:28 4.; and it is better exposed in the hillside 150 yards, more or less, southwest of the house.
