In the north-east dense forests, attaching themselves to the heart of the Ardennes, stretched almost without interruption from the German Ocean to the Rhine; and on the plains of Flanders and Lorraine, now so fertile, the Menapian and Treverian herdsman then fed his half-wild swine in the impenetrable oak-forest.
Just as in the valley of the Po the Romans made the production of wool and the culture of corn supersede the Celtic feeding of pigs on acorns, so the rearing of sheep and the agriculture in the plains of the Scheldt and the Maas are traceable to their influence.
