SACRED
to the memory of
CONROD CLINE,
who died August 8th 1837,
in the 28th year of his age.

Although the rest of the stone is damaged, the quotation is easily recognized as Revelation 14:13:

Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
