Wea. Fri. Nov. 5, 1909 Ther.
One of the guests at The Manor House autored me to Russell quarry. The clifing is now more extensive than ever. Made a new sketch of the beds.
Today I concluded that the conglomerate bed does not mean a basal one, but rather is another bottom slide like those of the Upper Safer. Here it is a case of dolomite beds sliding over a shale series. The whole series from the base of the slide beds are more or less fractured and jumbled and even the older shale is well dis- turbed. That there is no break in sedimentation is indicated by the lithology since all outside of the shale is of same general character.
That the older shale is of Upper Cambrian time is indicated by the presence of Dictyonema found one today, in fact saw our fossils here very kind.
The low ground over from Russell quarry to the ridge of dolomite is 200 yards across. In the Russell quarry to cliff is about 200 ft., and it is the same for the dol. to the W.
