Forests and heaths still also covered about half the surface. These were now the hunting-grounds of the kings and nobles, while in the leys, hursts, and dens, small groups of huts gave shelter to the swineherds and woodwards who had charge of their lord's property in the woodlands. The great tree-covered region of Selwood still divided Wessex into two halves; the forest of the Chilterns still spread close to the walls of London; the Peakland was still overgrown by an inaccessible thicket; and the long central ridge between Yorkshire and Scotland was still shadowed by primæval oaks, pinewoods, and beeches. Agriculture continued to be confined to the alluvial bottoms, and had nowhere as yet invaded the uplands, or even the stiffer and drier lowland regions, such as the Weald of Kent or the forests of Arden and Elmet. Only two elements broke the monotony of these self-sufficing agricultural communities. Those elements were the monasteries and the towns. A large part of the soil of England was owned by the monks. They now possessed considerable buildings, with stone churches of some pretensions, in which service was conducted with pomp and impressiveness. The tiny chapel of St. Lawrence, at Bradford-on-Avon, forms the best example of this primitive Romanesque architecture now surviving in England. Around the monasteries stretched their well-tilled lands, mostly reclaimed from fen or forest, and probably more scientifically cultivated than those of the neighbouring manors. Most of the monks were skilled in civilised handicrafts, introduced from the more cultivated continent. They were excellent ecclesiastical metalworkers; many of them were architects, who built in rude imitation of Romanesque models; and others were designers or illuminators of manuscripts. The books and charters of this age are delicately and minutely wrought out, though not with all the artistic elaboration of later mediæval work. The art of painting (almost always in miniature) was considerably advanced, the figures being well drawn, in rather stiff but not unlifelike attitudes, though perspective is very imperfectly understood, and hardly ever attempted. Later Anglo-Saxon architecture, such as that of Eadward's magnificent abbey church at Westminster (afterwards destroyed by Henry III. to make way for his own building), was not inferior to continental workmanship. All the arts practised in the abbeys were of direct Roman origin, and most of the words relating to them are immediately derived from the Latin. This is the case even with terms relating to such common objects as _candle_, _pen_, _wine_, and _oil_. Names of weights, measures, coins, and other exact quantitative ideas are also derived from Roman sources. Carpenters, smiths, bakers, tanners, and millers, were usually attached to the abbeys. Thus, in many cases, as at Glastonbury, Peterborough, Ripon, Beverley, and Bury St. Edmunds, the monastery grew into the nucleus of a
