"The pieces are laid down at all angles, often the stand edgewise. Some of these pieces bear Lower Cambrian fossils, and in one block I got Ptychomenus and Lingulella. The most abundant pieces are of a white tridoye like limestone, the same as the great block seen 6 miles north of St. Albans. Finally there are pieces of the sandy dolomite and of a black colored dolomite, one much further down in the Lower Cambrian series. Again are some on or schist, no granite. Some of the boulders of the marble like li. are five to six feet long. We also saw some blue black shale pieces included in the conglomerate. The great majority of pieces are angular. Beneath the blue li congl. we often saw a rounded dark slate, that in places seems interlaid with gritty sand in the beds. For these various occurrences ite appears there is but one explanation. It is of true mile recurrence to be of cliff origin, at the same offer true of torrential rivers. At 6 1/2 to 7 miles north of St. Albans we saw much black slate that was gray similar to the others, but it has nothing whatever!
