Giraldus intended to have written an itinerary or topography of England also, but his purpose does not appear to have been fulfilled. Higden, his immediate successor in that kind of writing a century and a half later, is content, in his section on England, to reproduce the generalities of earlier authors from Pliny downwards. Of these, we have already quoted the ‘Prerogatives of England’ by Henry of Huntingdon, from which one might infer that the British Isles, under the Norman yoke, were the Islands of the Blest. On the other hand, the impression made by the details of the Domesday survey upon a historian of the soundest judgment, Hallam, is an impression of poor cultivation and scanty sustenance. “There cannot be a more striking proof,” he says, “of the low condition of English agriculture in the eleventh century than is exhibited in Domesday book. Though almost all England had been partially cultivated, and we find nearly the same manors, except in the north, which exist at present, yet the value and extent of cultivated ground are inconceivably small. With every allowance for the inaccuracies and partialities of those by whom that famous survey was completed, we are lost in amazement at the constant recurrence of two or three carucates in demesne, with folkland occupied by ten or a dozen villeins, valued all together at forty shillings, as the return of a manor which now would yield a competent income to a gentleman[36].” Whether, the population at the Domesday survey were nearer two millions than one, the people were almost wholly on the land. Of the size of the chief towns, as the Normans found them, we may form a not incorrect estimate from the Domesday enumeration of houses held of the king or of other superiors[37]. London, Winchester and Bristol do not come at all into the survey. Besides these, the towns of the first rank are Norwich, York, Lincoln, Thetford, Colchester, Ipswich, Gloucester, Oxford, Cambridge, and Exeter.
