"oysters could see nothing of importance. Loc. 9 is the most southern anchorage made a vertical escarpment. The layers here are a very soft sandstone and sandy shale, About a mile south of the ridge are layers of impane lignite which Lawson says are five feet thick. Here various parties found leaves, of which Collier & Deloit have a large palm leaf fossil. Dr J. Stanford has some other and tells me that he has seen several species of Conifers, Fucoids, Platanae, Ficus and Dacafres. Prof Knight says that the horizon for most of the fossils collected is debatable since it is on or near the horizon of the Fort Pierre and Fox Hills. The latter he says continues with here and these marine fossil horizons 1 1/2 mile over the strata beyond my section in loc. 9. The Fox Hills he slips, in 7000 feet thick. A good collection was made by Mr. Andrew Kemper and will go to Gustavus Adolphus
