Mount Autumn has more limestone than the lower zones. One can say that in general the Mount Autumns seems more and more shale and that finally in the highest five feet all is practically a blue shale. In general the sections may be de- scribed as follows: Arnhem. Decidedly fossiliferous Amended li, with shales. Partly one li, than sh. Definite and Pseugra and one one just below center with fossils 8 feet. Arnhem & ft. shady-shaly limestone interior parts - 3-5 inches. Int. Autumn 18-19 feet are soft blue shales. 2 feet Li, 2 to 4 inches near face blue shales. Some thin li, 2/2 feet. Blue shales with more and more li, downwards. 9 feet. These beds have very rarely a Plety- stiffing liq (R. Jordenman also) occurs often but never more of li. with the bees standing like sandwiches. Blue shales and then bedded limestones about half and half. Most of the fossils collected are from here. 5 feet. Plectrothri occurs here little those found to fit on vines about there.
