When in the seventies the National Safe Deposit Company dug down some forty feet into the ground, and reached the ancient course of the Wallbrook, they found in its bed, among other debris, enormous quantities of broken vessels and kitchen utensils. No doubt the careless cooks and housemaids of the ancient Romans found the brook handy for getting rid of the evidences of mishap or recklessness; but their successors on the banks of the stream seem to have treated it with even greater disrespect. In the records of the City we find constant references to the disgraceful condition of the Wallbrook. In 1288 the Warden and Sheriffs of the City of London had to order that the watercourse of the Wallbrook should be made free from dung and other nuisances, and that the rakes should be put back again upon every tenement extending from Finsbury Moor to the Thames. In 1374 the Mayor and Aldermen granted to Thomas atte Ram, brewer, a seven years' lease of the Moor, together with charge of the watercourse of Wallbrook, without paying any rent therefor, upon the understanding that he should keep the said Moor well and properly, and have the Wallbrook cleansed for the whole of the term, clearing it from dung and other filth thrown therein, he taking for every latrine built upon the said watercourse twelve pence yearly. And if, in so cleansing it, he should find aught therein, he should have it for his own. But it would seem that Thomas atte Ram did not properly perform his contract, for at the expiration of it, namely in 1383, we find by an Ordinance of the Common Council that, 'whereas the watercourse of the Wallbrook is stopped up by divers filth and dung thrown thereinto by persons who have houses along the said course, to the great nuisance and damage of all the City, the Aldermen of the Wards of Coleman Street, Broad Street, Chepe, Wallbrook, Vintry and Dowgate, through whose wards the said watercourse runs, shall inquire if any person dwelling along the said course has a stable or other house, whereby dung or other filth may fall into the same; or otherwise throws therein such manner of filth by which the said watercourse is stopped up, and they (the Aldermen) shall pursue all such offenders. But it shall be lawful for those persons who have houses on the said stream to have latrines over it, provided they do not throw rubbish or other refuse through the same ... and every person having such latrines shall pay yearly to the Chamberlain two shillings for each of them.'

With such arrangements, and the constant increase of buildings on the brook, and the decrease of water supplied to it by the springs in Moorfields, which were gradually being laid dry, the Wallbrook, from a clear stream, became a foul ditch, an open sewer, so that it was found necessary to convert it into a covered one in reality. The brook was filled up with all kinds of debris and partially bricked over, so that when Stow wrote (in 1598) he was obliged to say: 'This watercourse ... was afterwards vaulted over with brick, and paved level with the streets and lanes ... and since that houses also have been built thereon, so that the course of Wallbrook is now hidden underground, and thereby hardly known.' The stream was covered in at least three centuries before the covering in of the Fleet river, but its course can still be traced by the many important buildings which lined its banks. Commencing at its influx to the Thames, there were along its course on the western side the halls of the Innholders, the Dyers, the Joiners, the Skinners, the Tallow-chandlers, and the Cutlers; the churches of St. John, St. Michael, St. Stephen (which originally stood on the western side), St. Mildred, and St. Margaret; also the Grocers' and the Founders' Halls, the estates of the Drapers and Leathersellers, and in Bucklersbury Cornet's Tower, a strong stone tower which was erected by Edward III. as his 'Exchange of money there to be kept.' In the sixteenth century it seems to have come into the possession of one Buckle, a grocer, who intended to erect in its place a 'goodly frame of timber,' but, 'greedily labouring to pull down the tower,' a part thereof fell upon and killed him.

In 1835 a curious discovery, the import of which was then unsuspected, was made close to the Swan's Nest, a public-house in Great Swan Alley, Moorgate Street. A pit or well was laid open, in which was found a large quantity of earthen vessels of various patterns. This well had been carefully planked over with stout boards; the vases it contained were placed on their sides, embedded in mud or sand, which had settled so closely round them that a great number were broken in the attempt to extricate them. A coin and some iron implements were also found in the well, which was about three feet square, and boarded on each side with narrow planks about two feet long. The object with which these vessels, etc., had been deposited in this well was not at the time surmised, but it was made clear by a subsequent discovery. When the National Safe Deposit Company's premises, already referred to, were built, a similar wooden framework was discovered at a depth of about thirty feet below the present level of the street. It was of oak, and about three feet square, and the contents of the box were similar to those found at the Swan's Nest. Fortunately this find came under the observation of Mr. John E. Price, F.S.A., and Honorary Secretary of the London and Middlesex Archæological Society, who recognised the remains as those of an arca finalis, a monument employed by the Roman surveyors to indicate the situation of limits of public or private property, answering to a landmark or boundary stone. Similar structures, occasionally of stone or tiles, have been discovered in other parts of England, as also on the Continent. It is therefore evident that the box found higher up the stream was also such an area.

To return once more to Wallbrook. A bridge across it we have not yet mentioned was Horseshoe Bridge, situate where the brook crossed Cloak Lane, which was a famous shopping-place of the ladies of those early days, fancy articles being mostly on sale there. It is, however, time to leave the Wallbrook; let us part from it with such a picture on our minds as will leave a vivid and pleasant impression. Remember that its banks were favourite sites for villas, as is proved by all the evidences of wealth and luxury of the ancient dwellers on the Wallbrook ravine and adjoining streets, now buried fathoms deep underground, which have been found on and near the banks of the river. 'A villa in beautiful grounds on the Wallbrook to be let'—think of that!

From the valley of the Wallbrook the ground of the City rises gently towards St. Paul's, and Panyer's Alley, the highest point; thence it falls almost precipitously towards the valley of the Fleet River, so precipitously, indeed, that one of the descents from the Old Bailey to Farringdon Street obtained the name of Breakneck Steps. When the increase of the population of the old City rendered it desirable to seek new habitations, the citizens looked across the river Fleet, and saw the opposite Holborn, Back, and Saffron Hills as yet unoccupied, stretching out as open country—though roads had begun to be established thereon, such as Field Lane, then in the fields—and began to erect dwellings on the western bank of the river. This led to the erection of bridges; we think Holborn Bridge was the first to be built. But before we enter into an account of the bridges, it is necessary to speak of the river itself.

The Fleet, then, which once formed so important a feature of London topography, took its rise in the dense clay of the district just below Hampstead; at Kentish Town its volume was increased by an affluent from Highgate Ponds; it then made its way through the hill near College Street—whence some writers infer that the name of Oldbourne, by which the river was known for some distance, was really a corruption of Hole-bourne—and entered the valley formed by the hills of Camden Town and the Caledonian Road, pursuing its course to Battle Bridge—since 1830 known as King's Cross—where it received an affluent from the west, which rose in the high ground to the south of the Hampstead Road. From Battle Bridge the river bent round to the east, and flowed through the grounds of Bagnigge Wells, once the residence of Nell Gwynne, and thence, still with an easterly trend, past the walls of the House of Correction, thence across Baynes Row, where it received another western affluent, taking its rise at the western end of Guilford Street. Thence it flowed to the northern end of Little Saffron Hill, and in this part of its course it sometimes was called the River of Wells, because it was fed by a number of wells or springs, all situate in Clerkenwell, and known as Clerks' Well, Skinners' Well, Faggs' Well, Loder's Well, Rad Well, and Todd's Well, this latter a corruption of its proper name, God's Well, from which Goswell Street took its name. The river thence flowed down the valley between the old City and the Holborn hills, and here it occasionally went by the name of Turnmill Brook, because of the mills which here stood on its banks. On its eastern side was a street called Turnmill Street, which in later days acquired a very bad reputation, its inhabitants being abandoned characters. Originally it was a respectable street, the houses having gardens going down to the river, which was fenced on both sides. In its southward course the river presently reached Holborn Bridge, where it received the affluent called the Hol-bourne, which rose somewhere near St. Giles'. The existence of this brook is denied by some topographers, but it is distinctly shown in a very old map of the manor of Blemundsbury (Bloomsbury), reproduced in Mr. W. Blott's 'Chronicle of Blemundsbury,' 1892. And we see no reason for doubting the correctness of the map, and therefore adopt the Holbourne as a fact. The Fleet then passed under Chick Lane, afterwards called West Street, which crossed the river at right angles, and in quite recent times was the refuge of thieves, burglars, and other criminals; and means of concealment and of escape by way of the river were revealed when, in the forties and fifties, West Street was pulled down for the improvements then in progress in that locality. After passing under Holborn Bridge, the river was known as the Fleet, not because of the fleetness of its course, as some writers would have it, for it never had much of that quality, but because of the flood or high tide it participated in with the rise of the Thames.

Having thus traced the river from its source to its mouth, we may describe the bridges which crossed it.

In the northern part of its course the river, where it passed through what in the early days was still country, was no doubt here and there crossed by bridges, but they were probably wooden bridges of light construction, as the traffic was but limited. The first solid bridge we have any record of is the one which existed at Battle Bridge, which derived its name from the battle between Suetonius Paulinus and Boadicea, the Queen of the Iceni, which is said to have been fought on the spot, and from the brick bridge which in early times there crossed the Fleet. Originally it was built of wood, but at an uncertain date later on it was replaced by one of brick, consisting of a number of arches. Battle Bridge, from the lowness of its situation, was exposed to frequent inundations. In the Gentleman's Magazine, May, 1818, we read: 'From the heavy rain which commenced yesterday ... Battle Bridge, St. Pancras, and part of Somers Town was inundated. The water was several feet deep in many of the houses, and covered an extent of upwards of a mile. The carcases of several sheep and goats were found ... and property was damaged to a very considerable amount.' Various Acts were passed at the beginning of this century for the improvement of the locality: the river was completely arched over, and in 1830 the spot assumed the name of King's Cross from the ridiculous structure erected in the centre of the cross roads; it was of octagon shape, surmounted by a statue of George IV. The basement was for some time occupied as a police-station, then as a public-house, and the whole was taken down in 1845, and a tall lamp erected on the spot.

The Fleet was next crossed by an ornamental, somewhat rustic bridge in the grounds of Bagnigge Wells; of course it disappeared with the gardens and buildings of the Wells in 1841. In the seventeenth and eighteenth centuries, when Clerkenwell, from an almost rural became an urban district, streets began to cross the Fleet, such as Baynes Row, Eyre Street Hill, Mutton Hill, Peter Street, and others. The next old bridge we came to was Cow Bridge, by Cow Lane, or the present Cow Cross. It dated from the middle of the sixteenth century. Stow, writing, it will be remembered, in 1598, says: 'This bridge being lately decayed, another of timber is made by Chick Lane.' In the time of Elizabeth the ground from Cow Cross towards the Fleet River, and towards Ely House, on the opposite bank, was either entirely vacant or occupied with gardens.

We next come to Chick Lane, afterwards known as West Street. Stow, writing in 1603, refers to Chicken Lane, 'toward Turnmill Brook, and over that brook by a timber bridge into the field.' This must have been Chick Lane, which was really a bridge of houses, the most noticeable of which was one which once had been known as the Red Lion Inn, and which at its demolition is supposed to have been three hundred years old. For the last hundred years of its existence it was used as a lodging-house, and was the resort of thieves, coiners, and other criminals. Its dark closets, trap-doors, sliding panels, and secret recesses rendered it one of the most secure places for robbery and murder; openings in the walls and floors afforded easy means of getting rid of the bodies by dropping them into the Fleet, which for many years before its final abolition was only known as the Fleet Ditch. The history and description of the houses in West Street were rendered so well known at the time of their demolition that we need not enter into them here; besides, they are beyond the scope of our inquiries.
