Higgins is the following:

"These ramparts inclose an area of 1400 feet in diameter, which on the
edge nearest the ditch was set round with a row of rough, unhewn stones,
and in the center was ornamented with two circular temples, composed of
the same native stones."(159)

The space of ground included within the vellum has been estimated at
twenty-two acres, and the outward circumvallation was computed at 4800
feet. The number of stones that formed this outer circle was originally
one hundred, of which, in the year 1722, there were eighteen standing,
and twenty-seven thrown down.

In the village of Rudstone in Yorkshire there stands a huge stone,
the significance of which, at the present time, is by scholars clearly
understood. Its depth below the surface of the ground is said to be
equal to its height above, which is twenty-four feet. It is five feet
ten inches broad, and two feet thick, its weight being upwards of forty
tons.(160)

The gigantic rocking stones found in nearly every quarter of the globe
are now known to be religious monuments of remote antiquity. Not long
ago I saw a description of one of these oracles in Buenos-Ayres, South
America, and a few months later there appeared the following account of
a similar stone found in Sullivan Co., N. Y.:

"At first sight it would scarcely attract attention, but a closer
observation reveals the remarkable position which it occupies. The total
weight of the immense boulder has been variously estimated at from forty
to fifty tons, and its bulk at from 500 to 700 cubic feet. It is almost
perfectly round, much resembling a huge orange, and so nicely balanced
on a table of stone as to be easily set in motion by a single man,
providing the operator exerts his strength on the north or south sides.
On either of the other sides the combined strength of forty elephants
would not be sufficient to cause the least oscillation. Although it
is easily rocked, we are assured that as many men as could surround it
would be unable to dislodge it from the pivot on which it rests."(161)

The writer of the above, who was evidently ignorant of the extent to
which these monuments are scattered over the earth, seemed to regard it
as a singular freak of Nature with no significance other than that of a
natural curiosity.
