July 16. Middle Point. Our third camp is beside a small horn about one mile east of the old mining farm and about 50 Quarries. This the first camp yet but we will leave it tomorrow. Where the Chazy comes in it is overlain by the Windor Shale or broken amyloante being present. Therefore the Chazy over-lies all the Ord. formations. The horn bottom in which our camp is pitched also has Windsor in it with sides of Chazy. Evidently the region is much faulted by small shifts. If for one day we have done in the south the relations of the Table Head series to the Chazy, nor to the Cow Head amyloante. All contacts are faulted. As the top of the Chazy is faulted we do not know its entire thickness. Of the Table Head series we do not know its thickness at all.
