Chapter 5: The Lake

There now only remains the geography of our country to be treated of before the history is commenced. Now the most striking difference between the country as we know it and as it was known to the ancients is the existence of the great Lake in the centre of the island. From the Red Rocks (by the Severn) hither, the most direct route a galley can follow is considered to be about 200 miles in length, and it is a journey which often takes a week even for a vessel well manned, because the course, as it turns round the islands, faces so many points of the compass, and therefore the oarsmen are sure to have to labour in the teeth of the wind, no matter which way it blows.

Many parts are still unexplored, and scarce anything known of their extent, even by repute. Until Felix Aquila’s time, the greater portion, indeed, had not even a name. Each community was well acquainted with the bay before its own city, and with the route to the next, but beyond that they were ignorant, and had no desire to learn. Yet the Lake cannot really be so long and broad as it seems, for the country could not contain it. The length is increased, almost trebled, by the islands and shoals, which will not permit of navigation in a straight line. For the most part, too, they follow the southern shore of the mainland, which is protected by a fringe of islets and banks from the storms which sweep over the open waters.

Thus rowing along round the gulfs and promontories, their voyage is thrice prolonged, but rendered nearly safe from the waves, which rise with incredible celerity before the gales. The slow ships of commerce, indeed, are often days in traversing the distance between one port and another, for they wait for the wind to blow abaft, and being heavy, deeply laden, built broad and flat-bottomed for shallows, and bluff at the bows, they drift like logs of timber. In canoes the hunters, indeed, sometimes pass swiftly from one place to another, venturing farther out to sea than the ships. They could pass yet more quickly were it not for the inquisition of the authorities at every city and port, who not only levy dues and fees for the treasury of the prince, and for their own rapacious desires, but demand whence the vessel comes, to whom she belongs, and whither she is bound, so that no ship can travel rapidly unless so armed as to shake off these inquisitors.

The canoes, therefore, travel at night and in calm weather many miles away from the shore, and thus escape, or slip by daylight among the reedy shallows, sheltered by the flags and willows from view. The ships of commerce haul up to the shore towards evening, and the crews, disembarking, light their fires and cook their food. There are, however, one or two gaps, as it were, in their usual course which they cannot pass in this leisurely manner; where the shore is exposed and rocky, or too shallow, and where they must reluctantly put forth, and sail from one horn of the land to the other.

The Lake is also divided into two unequal portions by the straits of White Horse, where vessels are often weather-bound, and cannot make way against the wind, which sets a current through the narrow channel. There is no tide; the sweet waters do not ebb and flow; but while I thus discourse, I have forgotten to state how they came to fill the middle of the country. Now, the philosopher Silvester, and those who seek after marvels, say that the passage of the dark body through space caused an immense volume of fresh water to fall in the shape of rain, and also that the growth of the forests distilled rain from the clouds. Let us leave these speculations to dreamers, and recount what is known to be.

For there is no tradition among the common people, who are extremely tenacious of such things, of any great rainfall, nor is there any mention of floods in the ancient manuscripts, nor is there any larger fall of rain now than was formerly the case. But the Lake itself tells us how it was formed, or as nearly as we shall ever know, and these facts were established by the expeditions lately sent out.

At the eastern extremity the Lake narrows, and finally is lost in the vast marshes which cover the site of the ancient London. Through these, no doubt, in the days of the old world there flowed the river Thames. By changes of the sea level and the sand that was brought up there must have grown great banks, which obstructed the stream. I have formerly mentioned the vast quantities of timber, the wreckage of towns and bridges which was carried down by the various rivers, and by none more so than by the Thames. These added to the accumulation, which increased the faster because the foundations of the ancient bridges held it like piles driven in for the purpose. And before this the river had become partially choked from the cloacæ of the ancient city which poured into it through enormous subterranean aqueducts and drains.

After a time all these shallows and banks became well matted together by the growth of weeds, of willows, and flags, while the tide, ebbing lower at each drawing back, left still more mud and sand. Now it is believed that when this had gone on for a time, the waters of the river, unable to find a channel, began to overflow up into the deserted streets, and especially to fill the underground passages and drains, of which the number and extent was beyond all the power of words to describe. These, by the force of the water, were burst up, and the houses fell in.

For this marvellous city, of which such legends are related, was after all only of brick, and when the ivy grew over and trees and shrubs sprang up, and, lastly, the waters underneath burst in, this huge metropolis was soon overthrown. At this day all those parts which were built upon low ground are marshes and swamps. Those houses that were upon high ground were, of course, like the other towns, ransacked of all they contained by the remnant that was left; the iron, too, was extracted. Trees growing up by them in time cracked the walls, and they fell in. Trees and bushes covered them; ivy and nettles concealed the crumbling masses of brick.

The same was the case with the lesser cities and towns whose sites are known in the woods. For though many of our present towns bear the ancient names, they do not stand upon the ancient sites, but are two or three, and sometimes ten miles distant. The founders carried with them the name of their original residence.

Thus the low-lying parts of the mighty city of London became swamps, and the higher grounds were clad with bushes. The very largest of the buildings fell in, and there was nothing visible but trees and hawthorns on the upper lands, and willows, flags, reeds, and rushes on the lower. These crumbling ruins still more choked the stream, and almost, if not quite, turned it back. If any water ooze past, it is not perceptible, and there is no channel through to the salt ocean. It is a vast stagnant swamp, which no man dare enter, since death would be his inevitable fate.

There exhales from this oozy mass so fatal a vapour that no animal can endure it. The black water bears a greenish-brown floating scum, which for ever bubbles up from the putrid mud of the bottom. When the wind collects the miasma, and, as it were, presses it together, it becomes visible as a low cloud which hangs over the place. The cloud does not advance beyond the limit of the marsh, seeming to stay there by some constant attraction; and well it is for us that it does not, since at such times when the vapour is thickest, the very wildfowl leave the reeds, and fly from the poison. There are no fishes, neither can eels exist in the mud, nor even newts. It is dead.

The flags and reeds are coated with slime and noisome to the touch; there is one place where even these do not grow, and where there is nothing but an oily liquid, green and rank. It is plain there are no fishes in the water, for herons do not go thither, nor the kingfishers, not one of which approaches the spot. They say the sun is sometimes hidden by the vapour when it is thickest, but I do not see how any can tell this, since they could not enter the cloud, as to breathe it when collected by the wind is immediately fatal. For all the rottenness of a thousand years and of many hundred millions of human beings is there festering under the stagnant water, which has sunk down into and penetrated the earth, and floated up to the surface the contents of the buried cloacæ.

Many scores of men have, I fear, perished in the attempt to enter this fearful place, carried on by their desire of gain. For it can scarcely be disputed that untold treasures lie hidden therein, but guarded by terrors greater than fiery serpents. These have usually made their endeavours to enter in severe and continued frost, or in the height of a drought. Frost diminishes the power of the vapour, and the marshes can then, too, be partially traversed, for there is no channel for a boat. But the moment anything be moved, whether it be a bush, or a willow, even a flag, if the ice be broken, the pestilence rises yet stronger. Besides which, there are portions which never freeze, and which may be approached unawares, or a turn of the wind may drift the gas towards the explorer.

In the midst of summer, after long heat, the vapour rises, and is in a degree dissipated into the sky, and then by following devious ways an entrance may be effected, but always at the cost of illness. If the explorer be unable to quit the spot before night, whether in summer or winter, his death is certain. In the earlier times some bold and adventurous men did indeed succeed in getting a few jewels, but since then the marsh has become more dangerous, and its pestilent character, indeed, increases year by year, as the stagnant water penetrates deeper. So that now for very many years no such attempts have been made.
