Mounted on their ships, sixty to eighty feet long, by ten or fifteen broad, of which a specimen can be seen at the museum of Kiel,[32] the dwellers on the shores of the Baltic and North Sea had at first organised plundering expeditions against the great island. They came periodically and laid waste the coasts; and on account of them the inhabitants gave to this part of the land the name _Littus Saxonicum_. Each time the pirates met with less resistance, and found the country more disorganised. In the course of the fifth century they saw they had no need to return annually to their morasses, and that they could without trouble remain within reach of plunder. They settled first in the islands, then on the coasts, and by degrees in the interior. Among them were Goths or Jutes of Denmark (Jutland), Frisians, Franks, Angles from Schleswig, and Saxons from the vast lands between the Elbe and Rhine. These last two, especially, came in great numbers, occupied wide territories, and founded lasting kingdoms. The Angles, whose name was to remain affixed to the whole nation, occupied Northumberland, a part of the centre, and the north-east coast, from Scotland to the present county of Essex; the Saxons settled further south, in the regions which were called from them Essex, Sussex, Middlesex, and Wessex: Saxons of the east, south, centre, and west. It was in these two groups of tribes, or kingdoms, that literature reached the greatest development, and it was principally between them also that the struggle for supremacy set in, after the conquest. Hence the name of Anglo-Saxons generally given to the inhabitants of the soil, in respect of the period during which purely Germanic dialects were spoken in England. This composite word, recently the cause of many quarrels, has the advantage of being clear; long habit is in its favour; and its very form suits an epoch when the country was not unified, but belonged to two principal agglomerations of tribes, that of the Angles and that of the Saxons.[33] In the same way as in Gaul, the invaders found themselves in the presence of a people infinitely more civilised than themselves, skilled in the arts, excellent agriculturists, rich traders, on whose soil arose those large towns that the Romans had fortified, and connected by roads. Never had they beheld anything like it, nor had they names for such things. They had in consequence to make additions to their vocabulary. Not knowing how to designate these unfamiliar objects, they left them the names they bore in the language of the inhabitants: _castrum_, _strata_, _colonia_; which became in their language _chester_, _street_, or _strat_, as in Stratford, and _coln_ as in Lincoln.
