er, then,
that Wiltshire boasts of two thousand similar sepulchral mounds; and
that he can, within an easy distance of Stonehenge, find three hundred
of them, while in the same radius he will only encounter two Long
Barrows.

The proportion, therefore, of round to long is considerable, viz.
1:150. The figures of round and long for the entire county are
eighty-six Long to two thousand Round Barrows, or 1:24. In other words
there are five times more Round Barrows in the Stonehenge District,
than there are anywhere else in Wiltshire, taking Long and Round
Barrows together. This disproportion in distribution cannot altogether
be the result of accident; it must bespeak a special attraction for
the spot by the builders of the Barrows, and from the very fact that
Stonehenge was erected at a time when these people were first arriving
on Salisbury Plain, it does not seem extravagant to claim that they
had some reason for wishing their remains finally to rest within easy
distance of what must have been to them a sacred spot.

As already noted, these Round Barrows can be divided into three
classes: 1. The simple Bowl-shaped Barrow, that most frequently
encountered, having a diameter of from twenty to sixty feet, and a
height of from three to five feet. 2. The Bell-shaped Barrow which
reaches its highest development on the plain round Stonehenge, and is
more common and more beautiful in Wiltshire than in any other part of
England.

Indeed, the Stonehenge Bell Barrows are the very crown of the
Sepulchral Mound on Salisbury Plain. Unlike the Long Barrow, they are
entirely surrounded by a circular ditch, from which material for the
Mound has been excavated; within the ditch is a circular area level
with the turf, from which the mound rises from five to fifteen feet in
a graceful conical form. The diameter will be upwards of one hundred
feet, so that the entire structure is considerably larger and more
impressive than the Bowl Barrow.

3. "The Disc Barrow," so named by Dr. Thurnam, the great Barrow
expert, from its resemblance to a flat dish surrounded by a deep rim.
It consists of a circular area, level with surrounding turf, having a
diameter of about one hundred feet. This circular area is enclosed by
a ditch with a bank on the outside, both usually very regular and well
constructed. Within, at the centre, is a mound not more than a foot
high containing the se
