Groups Lime Kiln, 1½ mi S, a little over 4 mi E, N to homey, then NE up shale gully, 22 ft above brice level = top of Brass field exposures = 922 ft = contact w/ Dayltm here at me. = ¼ mi NW by 955 on Brandt pike, From Andler Falls 4 mi S, 3½ mi E. Brassfield outcrops 10th road E of brice. On same road, just E of mine, road turns off S mile. Half a mile South on this road the Brassfield (Lyme joint?) is exposed near 880 ft. Three quarters of a mile farther S, ½ mi S of Corner 902, top of Brass- field is near 900 ft level. On National pike, about half way between Brassfield exposures (1 mi E of Tanglewood) and road corner 972 is rock which looks like jendo euphemia of Andler Falls section, near 935 ft. SW corner 972, about ½ mile, went old house now removed. Brassfield top = about 940 ac- cording to map. Apparently too high judging from other sections The Dayltm limestone once was married here. Chiefly thin and with clay between, except in lower 1 ft of section. Overal Dayltm section at least 1 ft thick. This is like the southern phase of the Dayltm seen NE & SE of Tandalia for miles. From road corner 972, 1½ mile east of Tanglewood, SE 1 mile, then east ⅓ mile to old mill. Brassfield - top of exposure at 910. Base probably somewhere near 895 - but neither top nor both my contacts are actually exposed. east of Speaker from ½ to ¾ mi. joint lutes strike Magazine ridge, looks like Dayltm. Rock is thickly jointed also on going down the hill eastward. West from Chambersburg 1½ mi. Then SW from corner 937. Dayltm limestone in vertical section of 15 ft, but slopes 8 miles = 10 ft perhaps. Thin bedded E. in clay between. Next page,
