Thus ended the British rule over Norfolk and Suffolk. From this time date the existing walls of Colchester. The conquerors were determined not to risk a repetition of the destruction of their first colony, and, choosing a new site, one mile to the east of the former city, they planted their walls on the ridge on which Colchester now stands, overlooking the valley of the Colne. These walls, enclosing an area of 1000 by 600 yards, still remain, after the passing of more than eighteen hundred years, the most perfect Roman fortifications in Britain. Even in that wide space of time the town of Colchester has not extended very greatly beyond them. In some directions, indeed--notably to the north and north-east and on the west--the ramparts still look out upon the open country. The walls have a thickness of from seven to eight feet, and are built of red Roman tiles, alternating with courses of stones, brought with great labour from the coast near Harwich; the neighbourhood of Colchester, and Essex in general, being quite innocent of stone of any kind. Harwich and the seashore even to this day supply the boulders of limestone from which the building-stones of Colchester's walls were cut. Colchester was never again attacked during the period of more than three hundred years, in which the Romans ruled. In the events of A.D. 61, they had learnt the double lesson of being armed and of treating a foe, once conquered, with generosity. In the period between these events and the year 410, when the Imperial forces were withdrawn from Britain to help save the heart of the Empire from ruin, conquered and conquerors had to live together, and made the best of the necessity. Roman colonists intermarried with the gradually Romanised British, and the race of Romano-Britons thus created, during three centuries, gradually grew to look upon Britain as their home and themselves as a nation. Thus, towards the end, usurpers of the Imperial authority are found setting up as independent sovereigns, and civilised British princes treating on equal terms with Roman statesmen. In this way the British in some measure came into their own again, and to these circumstances we owe the wild legends of that mysterious monarch, "old King Cole," who is to Colchester what King Arthur is to Cornwall, the great local hero. "Colking's Castle," on Colchester's walls, and the earthworks near Lexden known as "King Cole's Kitchen"; nay, the very name of Colchester itself--"Cole's Chester," or castle, derive, according to legends, from this scarce more than mythical personage. Those stories make him one Coel, or Collius, the last of a line of semi-independent British kings who were allowed to retain a nominal sovereignty after Cunobelin's death and the Roman conquest. The story goes on to tell how, on the death of the usurper Carausius, in A.D. 293, Coel surrendered the country to the Emperor Constantius Chlorus, on that successor of the Cæsar's marrying his daughter Helena, who
