Hay, containing:364 inhabitants. This parish is situated on the small river Garrow, or Arrow, and contains some large
tracts of fertile and productive land in a good state of cultivation, and a considerable portion of common, part of which
is a turbary, called Rhos Goch, producing very fine peat, which is dug to the depth of fifteen feet from the surface.
Beneath the peat are strata of blue clay and of a clay of a yellow hue, the latter abounding with sea shells, which
crumble on the slightest touch the layer is about two feet in depth, and appears to be incumbent on water, which rises up
through the fissures occasionally made with the spade, and soon fills the whole cavity. The living is a rectory, in the
archdeaconry of Brecknock, and diocese of St. David's, rated in the king's books at 11.6. 8., and in the patronage of the
Bishop of St. David's. The church, dedicated to St. Michael, consists of a nave and chancel, but is not distinguished by
any architectural features deserving of notice. Richard Jones, in 1706, and an unknown benefactor, gave each a portion of
land, directing the rental to be distributed among the poor of this parish. The average annual expenditure for the support
of the spoor amounts to £204. 3.
