It is sufficiently clear (and the reading of any of our most positive modern authorities upon Domesday will make it clearer) that no sort of statistical exactitude can be arrived at for the population of the boroughs in the early Middle Ages. But when we consider that Reading is certainly underestimated, and when we consider the detail in which we are informed of Old Windsor, Wallingford, and Oxford, with the neglect of Abingdon, Lechlade, Cricklade, and Dorchester, one can roughly say that the Thames above London possessed in Staines, Windsor, Cookham, probably Henley, perhaps Bensington, Dorchester, Eynsham, and possibly Buscot, large villages varying from some hundreds in population to a little over 1000, not defended, not reckoned as towns, and agricultural in character. To these we may add Chertsey, Ealing, and a few others whose proximity to London makes it difficult for us to judge except in the vaguest way their true importance. In another category, possessing a different type of communal life, already thinking of themselves as towns, we should have Cricklade, Lechlade, Abingdon, and Kingston among the smaller, though probably possessing a population not much larger than that of the larger villages; while of considerable centres there were but three: Reading the smallest, almost a town, but one upon which we have no true or sufficient data; Wallingford the largest, with the population of a flourishing county town in our own days, and Oxford, a place which, though in worse repair, ran Wallingford close. Henley affords an interesting study. At the time of the Conquest, Bensington was no longer, Henley not yet, a borough. To trace the growth of Henley is especially engrossing, because it is one of the very rare examples of a process which earlier generations of historians, and notably the popular historians like Freeman and the Rev. Mr Green, took to be a common feature in the story of this island. They were wrong, of course, and they have been widely and deservedly ridiculed for imagining that the greater part of our English boroughs grew up since the barbarian invasions upon waste places. On the contrary most of our towns grew up upon Roman and pre-Roman foundations, and are continuous with the pre-historic past. But Henley forms a very interesting exception.
