84. The sandstone at this place is [illegible] probably the Cambrian sand- etone, but I do not learn certainly, if it is Cambrian, thn, some Cambrian slate has been changed to a very fine grained almost adinse rock. The sandstone is evidently folded thus a four times in the short exposures and is cut off transversely to the strike of the folds by the Archæan limestone on the north, while the Archæan on the south may have been originally so north the sandstones. The pres- ence of fluorine here suggests the opening of fissures here, and the probability is that the sand- estone is faulted in here. No case report of this sandstone dipping under the Archæan limestone I do not believe, as looks a little that way at me.
