a dip of 30° to the east. Dr. roots 300 feet over the beds are nearly horizontal and still further west begin to dip in the other direction. This is then to copy of an arch. On the very large Ormsbury quarry on the upper most layers the common fossil is the little button like Receptaculites = Cyclotomus common in Tennessee, Frith are abundant but can not be counted out of the limestone. These recognized are Theftosoma arai- culum, Raphistoma lenticulare. In the light blue or grey limestone (breathing a milky white) saw on fossils. It is these conchi- dally fracturing light blue limestone in heavy beds that is quarried here on an extensive scale for lime burning. They end abruptly and then follows thinner irregular bedded and less pure limestones. Are all these upper beds (judging between 100 to 200 foot thick) to be regarded as Trenton and the light blue beds below the Homer River series? There is a very decided change in the limestone de- sposits at this horizon. The upper remains of our north while the lower brings to mind the Kirk Bridge region of Kentucky. In the lower li. same oph-diopseting. The [illegible] at the contact with the limestone shows it to be typical Utica.
