35 feet thick. Of course there is more limestone down in the cut but this all that one could successfully mea- sure. In this thickness there are about 2833 traps by actual count. In other ones there are about 81 to each foot. Some of the traps are 1/2, 1, 2 inches dep. One dolomite grain is 4 1/2 inches across un- tended. There are 660 traps above the dolomite and the rest are below it. Then going to Daniel Dr. Russell lodges. Here on the eastern side is a small quarry for slaty dolomite for road metal. There are two Russell lodges on either side of the road. In the quarry the top are dolomite embo- domed in thick beds. These are the base of the Bilton. Below are slaty dolomites in beds from 1/2 inch to 1 inch, and at the top of these are many minute hashiforms of Linnarsonella and two other inarticulates. See the list of specimens. This place is 1 1/4 mile north, 10 degrees east of Highgate Center. The reign is in the top of the Ordovician, and is now the top of the Lower Cambrian. The valley is of Ordovician shales and limestone, with the finding of these fossils which may be Ordovician reality 2 or miles east of Highgate.
