southern to the northern rises of land), and as must also have been the long stretch of the right bank below Reading. The highest spring tides may have been felt as high up the stream as Staines, and both the character of the surface and the contour lines permit one to conjecture that the valley of the Wandle and several other inlets from the lower river were flooded. Yet it is remarkable that in this alluvium, more disturbed and dug than any other in Europe, little or nothing of human relics, of boats, or of piles has been discovered, and this absence of testimony also points to the remoteness of date from which we should reckon the human control of the river.

Here, as in many other conjectures concerning early history or pre-history, one is convinced of that safe rule which, in Europe at least, bids us never exaggerate the changes achieved by the last few centuries or the contrast between recorded and unrecorded things.

The tendency of most modern history in this country has been to exaggerate such changes and such contrasts. In the greater part of modern popular history care is taken to emphasise the difference between the Middle and Dark Ages and the last few centuries. The forests of England are represented as impassable, or nearly so; the numbers of the population are grossly underestimated; the towns which have had a continuous municipal existence of 1500 years are represented as villages.

The same spirit would tend to make of the Thames Valley in the Dark and Middle Ages a very different landscape from that which we see to-day. The floods were indeed more common and the passage of the river somewhat more difficult; cultivation did not everywhere approach the banks as it does now; and in two or three spots where there has been a great development of modern building, notably at Reading, and, of course, in London, the banks have been artificially strengthened. But with these exceptions it may be confidently asserted that no belt of densely inhabited landscape in England has changed so little in its natural features as the Thames Valley.

There are dozens of reaches upon the upper Thames where little is in sight save the willows, the meadows, and a village church tower, which present exactly the same aspect to-day as they did when that church was first built. You might put a man of the fifteenth century on to the water below St. John's Lock, and, until he came to Buscot Lock, he would hardly know that he had passed into a time other than his own. The same steeple of Lechlade would stand as a permanent landmark beyond the fields, and, a long way off, the same church of Eaton Hastings, which he had known, would show above the trees.

There is another method of judging the comparative smallness of the change, and it is a method which can be applied to many other parts of England whose desertion or wildness in the Dark and early Middle Ages has been too confidently asserted. That method is to note where human settlements were and are found. With the exception of the long and probably marshy piece between Radcot and Shifford the whole of the upper Thames was dotted with such settlements, which, though small, were quite close to the banks. Kelmscott is right up against the river in what one would otherwise have imagined to be land too marshy for building until modern times. Buscot, on the other bank, is not only close to the river, but was a royal manor of high historical importance in the eleventh century. Eaton Hastings is similarly placed right against the bank; so was in its day the palace of Kempsford above Lechlade, and so is the church of Inglesham between the two. All the way down you have at intervals old stonework and old place names, indicating habitation upon the upper Thames.

A proper system of locks is comparatively modern on any European river. The invention is even said (upon doubtful authority) to be as late as the sixteenth century, but the method of regulating the waters of a river by weirs is immemorial.

We have no earlier record of weirs upon the Thames than that in Magna Charta; but some such system must have existed from the time when men first used the Thames in a regular manner for commerce.

There is but one place left in which one can still reconstruct for oneself the aspect of such weirs as were till but little more than a century ago the universal method of canalising the river. Modern weirs are merely adjuncts to locks, and are usually found upon a branch of the stream other than that which leads up to the lock. But in this weir the old fashion of crossing the whole stream is still preserved. There is no lock, and when a boat would pass up or down the paddles of the weir have to be lifted. It is, in a modern journey upon the upper Thames, the one faint incident which the day affords, for if one is going down the stream but few paddles are lifted, and the boat shoots a small rapid, while to admit a boat going up stream the whole weir is raised, and, even so, a great rush of water opposes the boat as it is hauled through. Some years ago there were several of these weirs upon the upper river. They have all been superseded by locks, and it is probable that this last one will not long survive.

Such weirs did certainly sufficiently regulate the stream as to make its banks regularly habitable. If no local order, at least the interest of villagers in their mills sufficed to the watching of the stream.

We have in the place names upon the Thames a further evidence of the antiquity of its regulation, for, as will be seen in a moment, none give proof of any important settlement later than the eleventh century.

These place names not only indicate a continuous and early settlement of the banks, but also form in themselves a very interesting series, whose etymology is a little section of the history of England.

Of purely Celtic names very few survive in the sites of human habitation, though the names of the waterways are almost universally Celtic, as is the name of Thames itself. But it is probable that in the Saxon names which line the river there are many corruptions of Celtic words made to sound in the Saxon fashion. We cannot prove such origins. We can surmise with justice that the "tons" and "dons" all up and down England are Celtic terminations; they are almost unknown in Germany. There is a somewhat pedantic guess, drawn (it is said) from Iceland, that we got this national name ending from Scandinavia; so universal a habit would hardly have arisen from an admixture of Scandinavian blood received at the very close of the Dark Ages and affecting but small patches of North England. Moreover, as against this theory, there is the fact that quite half the Celtic place names mentioned in our early history and in that of Gaul had a similar termination. London itself is the best example.

If, however, we neglect this termination, and consider the first part of the words in which it occurs (as in Abing-don, Bensing-ton, Ea-ton, etc.), we shall find that most of the place names are Saxon in form, and some certainly Saxon in derivation.

Thus Ea-ton, a name scattered all along the Thames, from its very source to the last reaches, is the "tun" by the water or stream. Clif-ton (as in Clifton-Hampden) is the "ton" on the cliff, a very marked feature of the left bank of the river at this place. Of Bensing-ton, now Benson, we know nothing, nor do we of the origin of the word Abing-don.

The names terminating in "ham" are, in their termination at least, certainly Teutonic; and the same may be true of most of those—but not all of those—ending in "ford." Ford may just as well be a Celtic as a Teutonic ending, and in either case means a "passage," a "going." It does not even in all cases indicate a shallow passage, though in the great majority of cases on the Thames it does indicate a place where one could cross the river on foot.
