dwelling places, they are now supposed to have been merely excavations
for the sake of the chalk or the flints contained therein, and possibly
adapted for the storage of grain. Of equal interest are the so-called
"dew ponds," of which a number are scattered here and there close to
the edge of the northern escarpment. Undoubtedly of prehistoric origin,
the art of making the pond has become traditional and some have been
built by shepherds still living. These pools of clear cool water high
up on the crest of a hill gain a mysterious air by their position, but
their existence is capable of a scientific explanation. Built in the
first place to be as nearly as possible non-conducting, with an
impervious "puddled" bottom, the pond is renewed every night to a
certain extent by the dew which trickles down each grass and reed stem
into the reservoir beneath, and to a much greater extent by the mists
which drift over the edge to descend in rain on the Weald. The pools
might well be called "cloud ponds."

The most lovely scenes, the best view points, are described in their
proper place. The question as to which is the finest section of the
Downs must be left to the individual explorer. To some natures the free
bare wind-swept expanse at the back of Brighton will appeal the most.
By others the secret woods which climb from hidden combe and dry gully,
mostly terminating in a bare top, and which are all west of the Arun,
will be considered incomparably the best. To every man of Lewes the
isolated mass of hills which rise on the east of the town are _the_
Downs. But all must be seen to be truly appreciated and loved as they
will be loved.

Hotels will not be found in the Downs; the tourist who cannot live
