stone enclosures whose walls have been subjected in a greater or less degree to the See also:action of See also:fire
.
They are generally situated on hills offering strong defensive positions
.
Their See also:form seems to have been determined by the See also:contour of the See also:flat summits which they enclose
.
The walls vary in See also:size, a few being up-wards of 12 ft. high, and are so broad that they See also:present the See also:appearance of embankments
.
Weak parts of the See also:defence are strengthened by See also:double or triple walls, and occasionally vast lines of ramparts, composed of large blocks of unhewn and unvitrified stones, envelop the vitrified centre at some distance from it
.
No See also:lime or See also:cement has been found in any of these structures, all of them presenting the peculiarity of being more or less consolidated by the See also:fusion of the rocks of which they are built
.
This fusion, which has been caused by the application of intense See also:heat, is not equally See also:complete in the various forts, or even in the walls of the same fort
.
In some cases the stones are only partially melted and calcined; in others their adjoining edges are fused so that they are firmly cemented together; in many instances pieces of See also:rock are enveloped in a glassy See also:enamel-like coating which binds them into a See also:uniform whole; and at times, though rarely, the entire length of the See also:wall presents one solid See also:mass of vitreous substance
.
Since See also:John See also:Williams—one of the earliest of See also:British geologists, and author of The See also:Mineral See also:Kingdom—first described these singular ruins in 1777, about fifty examples have been discovered in See also:Scotland
.
The most remarkable are Dun Mac Uisneachain (Dun Macsnoichan), the See also:ancient Beregonium, about 9 M
.
N.N.E. of See also:Oban; Tap o' Noth, in See also:Aberdeenshire; See also:Craig Phadraic, or Phadrick, near See also:Inverness; Dun Dhardhail (Dunjardil) in Glen See also:Nevis; Knockfarrail, near See also:Strathpeffer; Dun Creich, in See also:Sutherland; Finhaven, near Aberlemno; Barryhill, in See also:Perthshire; See also:Laws, near See also:Dundee; Dun See also:Gall and Burnt See also:Island, in Buteshire; Anwoth, in See also:Kirkcudbright; and Cowdenknowes, in See also:Berwickshire
.
Dun Mac Uisneachain is the largest in See also:area, being 250 yds. See also:long by 50 yds. broad
.
In the Tap o' Noth the walls are about 8 ft. high and between 20 and 30 ft. thick
.
In Dun Mac Uisneachain, Barryhill and Laws the remains of small rectangular dwellings have been found
.
For a long See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O. Eng. getidan, to happen, " even-tide," &c.; it is not directly related to Lat. tempus)

- TIME, STANDARD
time it was supposed that these forts were See also:peculiar to Scotland; but they are found also in See also:Londonderry and See also:Cavan, in See also:Ireland; in Upper See also:Lusatia, Bohemia, See also:Silesia, See also:Saxony and Thuringia; in the provinces on the See also:Rhine, especially in the neighbourhood of the See also:Nahe; in the Ucker See also:Lake, in See also:Brandenburg, where the walls are formed of burnt and smelted bricks; in See also:Hungary; and in several places in See also:France, such as Chateauvieux, Peran, La Courbe, Sainte Suzanne, See also:Puy de See also:Gaudy and Thauron
.
They have not been found in See also:England or See also:Wales
.
In some See also:continental forts the vitrified walls are supported by masses of unvitrified stone built up on each See also:side
