Looked at a number of other exposures going south to Hinstroy but in one place I did see another trilobite fragment. The Billiston is mainly a limestone formation [illegible] in very deep beds. Here and there are dolomite zones from one to several feet thick, and in a dark blue we are for the fossils. Some of the lie, the crinoids are less than once a less but the white mm granu- lar magnif and is my oechistric. In such material we can get no fossils except on weathered surfaces. The dolomites do not flow and that is the reason why we get what are dict. At one place we also saw some slate, dark blue. When Keith came to Hinstroy he told me that he had found a fine Lower Cambrian fossil locality, half- mile N.E. of Fmela Junction [= Martin junction on map]. Here olenides occurs in abundance and in better and harder rock than the olddom locality found yesterday morning. A little to the. East the Mallett is repeated by one thrusting; see the line of outcrops marked in my map by Keith. He thinks this may become a famous Chechester fossil place. It was a cold windy miserable day, and without chance for collecting. Brandon, Sep 26 1972. Tuesday.
