107) Continued, 543 D in other retusa lenticula, near clitella with leptacma obliqua ridgel Leptacma occurs me ft below at least. Line Columnaria fortilis delay between middle & Ann Rill ends. 108) 720 = top of Aggrad limestone, 109) top of lagrod limestone = 729 110) 705 = top red Aggrad limestone. But preceding records seem not reliable the should lead to top of largest layers of Lame nel since these limest layers occur in other periods above the Aggrad clay, and normally are 2 to 4 feet thick. Aggrad limestone 5½ ft. Gmu brown clay 25¼ ft. Basal Micajack 2ft Salina Clinton 3ft Cedar glades unit of here along Aggrad clay. Here. In the part of lower Aggrad clay is reddish purple in bands. 111) 38 in = Clinton, Cedar glades 20 ft. 112) No clear confined line but deep red day probably caused by disintegration of the rock. 113) 642 Columnaria halli 114) Only luster at highest point show presence of Madison, ~ 706. = 20m top -j massive Madison. 115 Madison massive, Middle part at 649½ to 7 upper Columnaria halli layers. Stone layer occurs about 5 ft below down- also Col. beds. No other data seen here. Top of lower Madison at 649. 116) Red bed = near base of psender- Madison with characteristic Columnaria alberta. 117) Large flat layers and ammonites lypograms- good collecting ground but no Leptacma. Partly lower Rill. sand and coarse bed at Ann Rill creek.
