St. Albans, July 6-1922. Thursday In the morning visited the Corlin ledge nearly five miles north, 10° E. of St. Albans as the crow flies. At the north end of the ledge there is a mass of shell lime limestone fully 140 ft long. Near the center occurs the small limestone trowel with Syntrophia calcifica, an elongate Syntrophia, and a species Jamesella. These Leith collected last year. Tried to find the limestone that last year furnished the cephalopods, but Leith could not locate it. In any event it appears the forms came taken out of a trowel and not a house in place. At this Corlin ledge there is a great amount of the Shell lime limestone, more than usual. The whole mass of conglomerate has been much squeezed, foliated and drawn out. All the limestone trowels look drawn out. I am urging Leith to look upon all the Corlin forms as shell trowels, and therefore to regard the Downton conglomerate as at the base of the Bedwonton. Hereatnuts and there are Shell lime or Brillianite. According the Upper Cambrian and Ordovician are below the Downton conglomerate and the forms are both to be referred to the Cambrian.
