in which they must once have been included, and are in some instances
lost from the language altogether, so much so as to be only partially
explicable even by scholars. The argument applies likewise, in their
degree, to camps, barrows, and other artificial earth-works.

Conclusions thus drawn, when established, rest upon a very firm
basis. They depend upon the number and appositeness of the facts,
and it would be very interesting to pursue this branch of evidence in

"Llyn Llyngclys," Lake of the Engulphed Court; "Ceven y Bedd," the
Ridge of the Grave; "Rhyd y Saeson," the Saxons' Ford.

III. Names of mixed natural and artificial objects, as "Coeten

The selection of names would demand much care and discretion. The
