fragments of horse bones in the sandy lower zone, of which we collected two teeth, which I take to be Pleistocene. Then started SE for a big ditch cut, and found Pierre shale on the way. The latter cut is about half a mile E by N from the Wellington Station. At the west end Pierre shales are exposed, with numerous concretions as at Boulder brickyards. Fossils were few, but we collected Baculites ovatus, Nuculidae etc. Returned to hotel at 6 p.m. Retired at 9:15. Saw one bluebird.
