In a
village in Worcestershire where an approach road crossed a brook by a
ford, during floods the current was sometimes so strong as to
constitute a danger to horses and carts. The village pundits
therefore, in council duly assembled, considered the matter, and after
an extended debate the following resolution was carried unanimously,
"That a notice board be erected on the spot bearing the inscription:
When this board _is covered with water_ it is dangerous to attempt to
cross the ford."
The numerous brooks in the Vale of Evesham supply ample water for the
stock, but in more elevated parts, especially on the chalk Downs of
Sussex, Hants, Wilts, and Dorset, provision is made for an artificial
water supply by what are called "dewponds." A shallow saucer-shaped
depression is dug out on the open Down, the bottom being made
water-tight by puddling with a well-rammed layer of impervious clay.
The first heavy rainfall fills the pond, and, the water being colder
than the air, the dew or mist condenses on its surface sufficiently,
in ordinary weather, to maintain the supply. In a dry time the sheep
can always reach the water, the pond having no banks, by the shelving
formation of the bottom. Sometimes a few trees are allowed to grow
round it; they also act as condensers, and their drip helps to fill
the pond.
