It certainly preserves its typical features and undoubted character along the immediate valley of the Missouri to Kansas City and beyond. Several of the Missouri geologists have recognized it in the surface clays covering most of the counties of that State north of the Missouri River. Bull. 158 7 Fossils in the loess.--Land and fresh-water shells belonging to recent species are found in great abundance in certain localities of the loess. They belong mostly to terrestrial species, but a few are distinctly aquatic. These fossils have not been noticed in northern Nebraska near the moraine, but mostly in southwestern Iowa and central Nebraska. Fragments of unios have been reported from northwestern Iowa, but they seem likely to have been derived from the graves of Indians, by whom they were used as ornaments. They may have been scattered also around camps where they were eaten. In the loess bluffs near the Missouri in southwestern Iowa patches of ash-colored loess are found connected with faint impressions, which seem to be traces of pieces of bark and driftwood, but such can not be positively stated. Some of the horizontal streaks and bands of ashy loess may mark the former deposition of vegetable matter which by its decay in its porous surroundings has reduced the sesquioxide of iron, which gives the yellow tinge to the loess, to a carbonate which has been removed. In several localities detached bones and teeth have been found 20 feet or more below the surface; but as a whole the loess is a remarkably barren deposit. In some localities certain horizons in the loess are very rich in fossil shells over considera...
