In ancient times the Romans planted a colony at Newcastle, throwing a bridge across the Tyne near the site of the low-level bridge shown in the prefixed engraving, and erecting a strong fortification above it on the high ground now occupied by the Central Railway Station. North and northwest lay a wild country, abounding in moors, mountains, and morasses, but occupied to a certain extent by fierce and barbarous tribes. To defend the young colony against their ravages, a strong wall was built by the Romans, extending from Wallsend on the north bank of the Tyne, a few miles below Newcastle, across the country to Burgh-upon-Sands on the Solway Firth. The remains of the wall are still to be traced in the less populous hill-districts of Northumberland. In the neighborhood of Newcastle they have been gradually effaced by the works of succeeding generations, though the "Wallsend" coal consumed in our household fires still serves to remind us of the great Roman work. After the withdrawal of the Romans, Northumbria became planted by immigrant Saxons from North Germany and Norsemen from Scandinavia, whose eorls or earls made Newcastle their principal seat. Then came the Normans, from whose _New_ Castle, built some eight hundred years since, the town derives its present name. The keep of this venerable structure, black with age and smoke, still stands entire at the northern end of the noble high-level bridge--the utilitarian work of modern times thus confronting the warlike relic of the older civilization. [Illustration: MAP OF NEWCASTLE DISTRICT.] The nearness of Newcastle to the Scotch Border was a great hinderance to its security and progress in the middle ages of English history. Indeed, the district between it and Berwick continued to be ravaged by moss-troopers long after the union of the crowns. The gentry lived in their strong Peel castles; even the larger farm-houses were fortified; and blood-hounds were trained for the purpose of tracking the cattle-reavers to their retreats in the hills. The judges of Assize rode from Carlisle to Newcastle guarded by an escort armed to the teeth. A tribute called "dagger and protection money" was annually paid by the sheriff of Newcastle for the purpose of providing daggers and other weapons for the escort; and, though the need of such protection has long since ceased, the tribute continues to be paid in broad gold pieces of the time of Charles the First. Until about the middle of last century the roads across Northumberland were little better than horse-tracks, and not many years since the primitive agricultural cart with solid wooden wheels was almost as common in the western parts of the county as it is in Spain now. The track of the old Roman road long continued to be the most practicable route between Newcastle and Carlisle, the traffic between the two towns having been carried on pack-horses until within a comparatively recent period.
