Menah Friday July 17-91. Yesterday in going over to Clifton I saw great piles of rock in the city of Menasha which I thought would prove to be Galena. Upon investigation this morning I learned that it was taken out of the river by the dredge and proving to be the lower Cherty layers of the Ordovica. If I remember the State Geological Map correctly the Ordovica is not plotted as forming thus far East. In a small quarry on the road to Appleton belonging to Jens Jorgensen and about one mile and one-half East of Menasha the Ordovica is again exposed on each side of the Over House. There is a distinct anticlinal to be observed in these two quarries. So fresh to day. Left for Oshkosh 2.05 P.M.
