As a whole, however, England still remained a purely agricultural country to the very end of the Anglo-Saxon period. It had but little foreign trade, and what little existed was chiefly confined to imports of articles of luxury (wine, silk, spices, and artistic works) for the wealthier nobles, and of ecclesiastical requisites, such as pictures, incense, relics, vestments, and like southern products for the churches and monasteries. The exports seem mainly to have consisted of slaves and wool, though hides may possibly have been sent out of the country, and a little of the famous English gold-work and embroidery was perhaps sold abroad in return for the few imported luxuries. But taking the country at a glance, we must still picture it to ourselves as composed almost entirely of separate agricultural manors, each now owned by a considerable landowner, and tilled mainly by his churls, whose position had sunk during the Danish wars to that of semi-servile tenants, owing customary rents of labour to their superiors. War had told against the independence of the lesser freemen, who found themselves compelled to choose themselves protectors among the higher born classes, till at last the theory became general that every man must have a lord. The noble himself lived upon his manor, accepted service from his churls in tilling his own homestead, and allowed them lands in return in the outlying portions of his estates. His sources of income were two only: first, the agricultural produce of his lands, thus tilled for him by free labour and by the hands of his serfs; and secondly, the breeding of slaves, shipped from the ports of London and Bristol for the markets of the south. The artisans depended wholly upon their lord, being often serfs, or else churls holding on service-tenure. The mass of England consisted of such manors, still largely interspersed with woodland, each with the wooden hall of its lord occupying the centre of the homestead, and with the huts of the churls and serfs among the hays and valleys of the outskirts. The butter and cheese, bread and bacon, were made at home; the corn was ground in the quern; the beer was brewed and the honey collected by the family. The spinner and weaver, the shoemaker, smith, and carpenter, were all parts of the household. Thus every manor was wholly self-sufficing and self-sustaining, and towns were rendered almost unnecessary.
