Surrey, so famed for good mutton, is supplied from this place. The
grass or herbage of these downs is full of the sweetest and the
most aromatic plants, such as nourish the sheep to a strange
degree; and the sheep's dung, again, nourishes that herbage to a
strange degree; so that the valleys are rendered extremely fruitful
by the washing of the water in hasty showers from off these hills.
An eminent instance of this is seen at Amesbury, in Wiltshire, the
next county to this; for it is the same thing in proportion over
this whole county. I was told that at this town there was a meadow
on the bank of the River Avon, which runs thence to Salisbury,
which was let for 12 pounds a year per acre for the grass only.
