St. Albans, July 5-1922 Wednesday. Started out at 9 a.m. About one mile north of Highgate beside the road saw the Highgate then-bedded limestone. Got a few bris, near all from Jamesella (Electrothis). Then went to Highgate Falls and beneath the first house east of the Electric Power House saw mill displayed the large one of thin bedded limestone, the grey being about 15 feet thick, some of these layers are full of fragmented trilobites. The horizon Keith in-cludes is an Ordovician formation (= dolomite), which he calls 'Lower Cambrian Age'. To my surprise Mr Clevell's turned up and all the trilobites are of Upper Cambrian kinds. There are two species of Agnostus, one of which is smooth. The Jamesella also occurs here. These fine thin layers of the Ordovician and all above it must go into the Upper Cambrian. Got quite a lot of fossils. Then went for lunch to Highgate Center, and just outside of the village in the very then bedded and twisted limestone of the Highgate got a few fossils. In one that Keith got the fossils that he couldn't determine as Upper Cambrian. In this same field at a bay or promontory got a number of Lingulella.
