fortune for three or four years, being even once, in 409, for a short time recognised as a legitimate partner in the empire by Honorius. With his later fortunes, however, and with the whole story of the fall of the Roman empire in the west we have no further concern. We have heard of the exit of the legions, but we never hear of their return, and we are probably justified in fixing on the date 407, the period of the usurper Constantine’s departure from our island, as the end of the Roman occupation of Britain. Writers and readers must alike lament the extremely jejune character of the history of that occupation. Since we lost the guidance of Tacitus, we have had scarcely anything that could be called a continuous and intelligible narrative of events; nor, unless some happy fortune could restore to us the lost books of Ammianus, is such literary assistance now to be expected. We are thus thrown back on such information as inscriptions, buried ruins, finds of coins may afford to the patient archæologist. And these have done something for us, though we may reasonably hope that the judicious use of the spade and pickaxe, guided by science and not by mere capricious quest for curiosities, may do much more. We may here notice very briefly some of the chief contributions which archæological research has thus made to history. 1. Of all the marks made by our imperial conquerors in this island, the most distinct and ineffaceable was that made by them as road-makers. Often indeed their works survive only as boundaries between parishes or counties, but sometimes we can see the track still going straight to its mark over hill and dale, and we say instinctively, “That must be a Roman road”. It was certainly not mere unskilfulness or ignorance of the science of road-making which led the _stratores viarum_ to draw their lines across the country with this uncompromising directness. The prime object of the officer charged with the work was essentially military, and for watching the movements of barbarian insurgents or preventing the ravages of marauders, the crests of the hills successively surmounted by the marching legions were invaluable posts of observation.
