Now we know that in the time of the Romans, most of the German races lived in a condition similar to that in which it appears from records they lived shortly after their great exodus, in the early centuries of the Christian era: sometimes on single farms, but generally in enclosed villages, with boundaries marked out by posts. They had a peculiar method of laying out new village districts, and the Romans found it difficult to understand the mode of farming customary to the country. Probably the dwellers in the marshes near the North Sea had, as Pliny writes, made the first simple dykes against the encroachments of the water; already were their dwellings built on small hillocks, which, in high tides, raised them above the water, and their sheep pastured in the summer on the grass of the new alluvial soil;[2] but further from the coast the peasant dwelt in his blockhouse, or within mud walls, which he then loved to whitewash. Herds of swine lay in the shadows of the woods,[3] horses and cattle grazed on the village meadows, and long-woolled sheep on the dry declivities of the hills. Large flocks of geese furnished down for soft pillows; the women wove linen on a simple loom, and dyed it with native plants, the madder and the blue woad; and made coats and mantles of skins, which had already borders of finer fur introduced from foreign parts. Well-trod commercial roads crossed the territory from the Rhine to the Vistula in every direction. The foreign trader, who brought articles of luxury and the gold coins of Rome in his wagon to the house of the countryman, exchanged them with him for the highly-prized feathers of the goose, smoked hams, and sausages, the horns of the ure ox and antlers of the stag, fur skins, and even articles of toilet, such as the blonde hair of slaves, and a fine pomade to colour the hair. He bought German carrots, which had been ordered as a delicacy by his Emperor Tiberius; he beheld with astonishment in the garden of his German host, gigantic radishes, and related to his country-people that a German had shown him honeycombs eight feet long.
