C. Dr. & St. Paul R.R. to the north west. Here the "lower buff" is seen to rest on the St. Petri landstone. Could not see it at the quarry in that part was filled with water but the quarry man said that white sand rock came in there "below the limestone". The entire "lower blue beds" and about 15 feet of the "upper buff beds" are also exposed in this quarry. Fossils not as numerous here as in the quarry to the south. In the afternoon looked over the rocks thrown over the canal embankments near the woolen mill to the west of Janesville. Found the usual fossils. Sagto- joda and Pelecypoda most abundant.
