is quarried by Messrs. Sharpe and Carlisle. The quarry is something
over a hundred feet above the Hocking canal, and is opened in a hard
compact but coarse grained sandrock about twenty feet in thickness and
of excellent quality. Above this were exposed about fifteen feet of loose
laminated sandrock.
Just below the village of Sugar Grove, on the east side of the canal, is
the quarry of Robert L. Sharpe, Esq., in the same geological range as the
quarry last mentioned. Fossils are rare. I saw only an indistinct spirifer. The section is as follows. (See Fig. 3.)

The stone from the two quarries last named has been principally used
for locks and bridge piers, and is said to give good satisfaction. On the
Ohio and Erie canal this stone was used in rebuilding locks at Lockbourne
and at Lockville, making about twenty-five locks in all. It was also used
in the acqueduct and locks at Circleville. It has also been used at various points on the Hocking canal. The stone has been thus used for some
thirty years, and on the Ohio canal for fifteen years, and is reported to
stand the test admirably. Mr. Sharpe reports the gross sales from the
lower quarry last year at $12,000. The present year will probably show
$15,000 from the two quarries.
The following is a section showing the alternation of conglomerate and
fine grained blue sandstone as we ascend in the Waverly series. Being
taken in a deep railroad cut where no measurement could be made of the
perpendicular sides, the figures are only estimates. The section was taken
on the farm of James Francisco, Marion township, Hocking county. (See
Fig. 4.)
