To return to the ground we have already briefly covered, and to establish a comparison with Wallingford, the word "haga," which we saw to be of such doubtful value in the case of Wallingford, is replaced in Oxford by the word "mansio." The taxable units so enumerated are just over 600, but of these much more than half are set down as untaxable or imperfectly taxable under the epithets "Uasta," "Uastæ." What that epithet means we do not know. It may mean anything between "out of repair," "excused from taxation because they do not come up to our new standard of the way in which a house in a borough should be kept up, and because we want to give them time to put themselves in order," down to the popular acceptation of the word as meaning "ruined," or even "destroyed."

We know that at the close of the eleventh century, or indeed at any time before the thirteenth, the small man who lived under his own roof would live in a very low house, and that, space for space of ground area, the cubical contents of these poor dwellings would be less than those of modern slums. On the other hand, we know that the population would live much more in the open air, slept much more huddled, and also that a very considerable proportion—what proportion we cannot say, but probably quite half of a Norman borough—was connected with the huge communal institutions—military, ecclesiastical, and for that matter mercantile, as well—which marked the period. We know that the occupied space stood for very much what is now enclosed by the line of the old walls, and we know that under modern conditions this space, in spite of our great empty public buildings, our sparsely inhabited wealthy houses, and our college gardens, can comfortably hold some 5000 people. We can say, therefore, at a guess, but only at a guess, that the Oxford of the Conquest must have had some 3000 people in it at the very least, and can hardly have had 10,000 at the most. These are wide limits, but anyone who shall pretend to make them narrower is imposing upon his readers with an appearance of positive knowledge which is the charlatanism of the colleges, and pretends to exact knowledge where he possesses nothing but the vague basis of antiquarian conjecture.

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.

It was a hamlet which went with the manor of Bensington, and that point alone is instructive, for it points to the insignificance of the place. When the lords of Bensington went hunting up on Chiltern they found on the far side of the hill, it may be presumed, a little clearing near the river. This was all that Henley was, and it is probable that even the church of the place was not built until quite late in the Christian period; there is at any rate an old tradition that Aldeburgh is the mother of Henley, and it is imagined by those who wrote monographs upon the locality that this tradition points to the church of Aldeburgh as the mother church of what was at first a chapel upon the riverside.

When we first hear of Henley it is already called a town, and the date of this is the first year of King John, 1199.

It must be remembered that the river had been developed and changed in that first century of orderly government under the Normans. Indeed one of the reforms which the aristocracy made much of in their revolt, and which is granted in Magna Charta, is the destruction of the King's weirs upon the Thames. But the weirs cannot have been permanently destroyed; though the public rights over the river were curtailed by Magna Charta, the system of regulation was founded and endured. It is probably this improvement on the great highway which led to the growth of Henley, and when Reading Minster had become the great thing it was late in the twelfth century, Henley must have felt the effect, for it would have afforded the nearest convenient stage down the river from the new and wealthy settlement round the Cluniac Abbey. In the thirteenth century—that is, in the first hundred years after the earliest mention we have of the place—Henley became rapidly more and more important. It seems to have afforded a convenient halting place whenever progress was made up river, especially a royal progress from Windsor. Edward I. stayed there constantly, and we possess a record of three dates which are very significant of this kind of journey. In the December of 1277 the King goes up river. On the sixteenth of the month he slept at Windsor, on the seventeenth at Henley, the next day at Abingdon; and in his son's time Henley has grown so much that it counts as one of the three only boroughs in the whole of Oxfordshire: Oxford and Woodstock are the two others.

It was in the thirteenth century also that a bridge was thrown across the river at this point—that is, Henley possessed a bridge long before Wallingford, and at a time when the river could be crossed by road in but very few places. The granting of a number of indulgences, and the promises of masses in the middle of the thirteenth century for this object, give us the date; and, what is perhaps equally interesting, this early bridge was of stone.

It is usual to think of the early bridges over the Thames as wooden bridges. Aft older generation was accustomed to many that still remained. This was true of the later Middle Ages, and of the torpor and neglect in building which followed the Reformation. But it was not true of the thirteenth and fourteenth centuries. The bridge at Henley, like the bridge of Wallingford and the later bridge of Abingdon, was of stone.
