Lindum and
Ratae for their tribal centres. In this territory remains of British
camps are found at Barrow, Folkingham, Ingoldsby, Revesby, and Wells.
Also traces of Roman camps are discoverable at Alkborough, Caistor,
Gainsborough, Gadney Hill, near Holbeach, Honington, near Grantham,
South Ormsby, and Yarborough. The Roman roads in this neighbourhood
are nearly perfect. There is Ermine Street on the eastern side of the
Cliff Hills and the Fosse Way, running S.W. from Lincoln. There is a
famous arch--the Newport--at Lincoln. It is one of the most perfect
specimens of Roman architecture in England. It is sunk fully eleven
feet below the present level of the street, and has two smaller
arches on each side, the one to the west being concealed by an
adjoining house. The Ermine Street passes through this gate, running
north from it for eleven or twelve miles as straight as an arrow.
Many Roman coins and ornaments have been found in the immediate
vicinity of this gate. In the Cloister garden of the Cathedral are
preserved a tesselated pavement and the sepulchral slab of a Roman
warrior.

LONDON.--Londonum, Londinium, the Augusta of the Romans. _Llyn
Din_--the Black Llyn or Lake, or perhaps from Celto-Saxon _dun_, or
_don_--a hill fort. This fort may have been situated where abouts St.
Paul's now stands, or, in a more extended form, it may have been
constituted by Tower Hill, Cornhill, and Ludgate Hill; bounded thus
by the Thames on the South, the Fleet on the West, and the Fen of
Moorfields and Finsbury (afterwards by Hounsditch and the Tower) on
the East.

It must be premised that the course of the Thames, the containing
bounds, the depth of the stream, the character of the rivulets--such
as the Lea, the Fleet, Wall-brook, West-Bourne, Tye-Bourne--presented
marked differences in early historic days from the appearance they
show to-day. The sites north and south of the line where London
Bridge now stands constituted firm ground, with a tendency to an
elevation in the north. These facts determined the position of the
British settlement. At that part of the river the Britons had, if not
a ford, at least a ferry, and finally a rough bridge--perhaps of
coracles or boats--the progenitor of the noble structure now
existing. The ferry went from what is now Dowgate to a similar
opening still existing to the west of St. Saviour's, Southwark.

A British settlement of an early date would not now be thought to
deserve the n
