HERTFORDSHIRE, a county (inland), bounded on the north by the county of Cambridge, on the northwest by the county of Bedford, on the west by the county of Buckingham, on the south by the county of Middlesex, and on the east by the county of Essex: it extends from 51° 37 to 52° 5 (N. Lat.), and from 13 (E.) to 46 (W. Lon.); and contains three hundred and thirty-seven thousand nine hundred and twenty acres, or five hundred and twenty-eight square miles. The population, in 1821, amounted to 129,714. The Celtic inhabitants of this part of Britain were the Cassii, or Cattieuchlani, whose country, long before the invasion of Csesar, was overrun by the Belgae (who had previously established themselves in the south-western part of England), and their capital city, Verulam, taken possession of by the conquerors. Of the operations of Csesar in the territory forming the modern county of Hertford, and his capture of Verulam, little more is known than what may be collected from the succinct narrative of this campaign by the conqueror himself; the result of it, however, was, that the British chief Cassivelaunus was obliged to sue for peace; which being granted, Mandubritius, the sovereign of the Cassii, had his dominions restored to him, and Caesar led back his army, along the Watling-street, to Richborough, where he embarked for the Continent. Shortly after the second invasion of Britain, in the reign of Claudius, in the revolt of the Iceni, under Boadicea, against the Romans, which commenced while the Roman army under Suetonius was engaged in the conquest of the Isle of Anglesey, the Britons, after utterly destroying the Roman colony and garrison of Camalodunum, advanced against Verulam with such an overwhelming force, that the Roman general, who had hastened back along the Watling-street to its relief, was compelled to retire, leaving Verulam to the same disastrous fate which had befallen Camalodunum, the city being sacked, and the inhabitants massacred. It was not long, however, before this important post again fell into the hands of the invaders, who renewed its fortifications, and appear to have erected a new fortress at Cheshunt, on the Ermin-street. In the Roman division of Britain, this territory was included in Flavia Cizsariensis; and under the Saxon octarchy part of it was comprised in the kingdom of Mercia, and part in that of the East Saxons, or Essex. In 794, Offa, the celebrated king of Mercia, died at Offley, in this county; and in 896, near Ware, Alfred captured the Danish ships, by obstructing the channel of the river Lea, so that they could not be brought down it. In his camp at Berkhampstead, in 1066, William the Conqueror took the oath to maintain the laws of Edward the Confessor. At Wheathampstead, in 1312, the barons assembled their forces against Edward II. and his favourite Gaveston. The year 1381 is memorable in this county for the transactions connected- with the suppression of Wat Tyler's rebellion, when Richard II. and his chief justice Tresilian, with a guard of a thousand men, came to St. Alban's.: a number of the insurgents, brought from the gaol at Hertford, were there executed, and the male inhabitants of the county, from fifteen to sixty years of age, were assembled in the great court of the abbey, and swore to be faithful subjects for the future; at Hertford also, Henry, Duke of Lancaster, afterwards Henry IV;, kept his court, at the time that Richard II. was deposed. Three of the most important battles, during the war between the houses of York and Lancaster, were fought "within the limits of this county, viz., in 1455, the first battle of St. Alban's, in which Henry VI. was wounded and made prisoner; in 1461, the second battle of St. Alban's, in which Margaret of Anjou was defeated by the Earl of Warwick; and in 1468, the decisive battle-of Barnet, in which the Earl of Warwick and ten thousand of his army were slain. It was from Theobalds that Charles I., in 1642, after receiving there the petitions of both houses of parliament, departed to place himself at the head of his army. This county lies partly within the diocese of London, and partly in that of Lincoln, the whole being included in the province of Canterbury. That part which is in the diocese of London comprises the deanery of Braughin, which is in the archdeaconry of Middlesex, and contains thirty-four parishes, and the archdeaconry and deanery of St. Alban, containing twenty-two parishes. The part which is in the diocese of Lincoln is included within the archdeaconry of Huntingdon, and comprises the four deaneries of Baldock, Berkhampstead, Hertford, and Hitchin, containing eighty parishes; the total number of parishes in the county being one .hundred and thirty-six, of which, sixty-seven are rectories, fifty-three Vicarages, and the remainder perpetual curacies, or consolidated with other parishes. For civil purposes it is divided into the eight hundreds of Braughin, Broadwater, Cashio (or the liberty of St. Alban's), Dacorum, Edwinstree, Hertford, Hitchin, and Pirton, and Odsey, in which are the borough and market-towns of Hertford and St. Alban's, and the market-towns of Bal- dock, Berkhampstead, Hatfield, Hemel-Hempstead, Hitdun, Hoddesdon, Rickmansworth, Standon, Stevenage, Bishop's Stortford, Tring, Ware, and Watford, and parts Off those of Chipping-Barnet and Royston. Two knights are returned to parliament for the shire, and two representatives for each of the two boroughs. Hertfordshire is included in the home circuit: the assizes are held at Hertford, where also are held the quarter sessions, except for the hundred of Cashio, or liberty of St. Alban's, which are held at St. Alban's. The county gaol is at Hertford. There are ninety-five acting magistrates. The rates raised in the county for the year ending March 25th, 1827, amounted to £ 109,072.19.; the expenditure to £108,054. 6., of which £93,064. 12. was applied to the relief of the poor. The natural features of Hertfordshire are of a gentle character, but it possesses scenes of considerable beauty: the southern parts of the county, the heights of which overlook part of the county of Middlesex, and command a prospect of the distant hills of Surrey, are eminently pleasing; while, for an extensive view over a rich vale, few prospects, without a great river, are more striking than that which is obtained from Lilley-Hoo. Considerable addition is also made to the beauty of this county by the mansions, villas, and ornamented grounds, of Hch proprietors, which present themselves in every direction. The scenery of Moor .park js particularly beau- tiful; and the various scenes round Ware, North Mimms, Watford, and the banks of all the streams from Berkhampstead and Hempstead, when viewed from the adjoining hills, are worthy of attention. With respect to the soil, it may be remarked that the vales through which the rivers and brooks flow are invariably composed of rich sandy loam, with the exception only of a small quantity of peat and marshy moor; that the slopes of the hills descending to these vales are inferior qualities of the same loams, and at the same time dry and sound; but that the flatter surfaces of the higher lands are composed of a wet and strong loam, sometimes so much so as to require hollow draining. The late secretary to the Board of Agriculture, Mr. Arthur Young, divides the soil into one district of loams, two of clay, one of chalk, and one of gravel; at the same time observing, that the soils intermingle in a remarkable manner, so that it is sometimes extremely "difficult to draw the boundary line between them. The district of the loams includes a very considerable portion of the county, no less than one hundred and forty-seven, thousand eight hundred and forty acres, and may properly be divided into flinty and sandy; the flinty loams spread into a considerable tract from the river Beane to the limits of the county beyond Berkhampstead, extending southward to the gravel and clay districts, and northward to that of the chalk; from Berkhampstead towards Chesham they are of a reddish colour: for some miles around Buntingford these loams are strong, and produce heavy crops of wheat; and from St. Alban's to Redbourn, and about Watford, they form a fine mellow turnip land, easily worked, and adapted to the production of almost every kind of grain. Some of the finest loam in the county is the sandy vale of Cheshunt up to Hoddesdon, which produces five quarters of wheat per acre. Some of these loams, more especially where they are wet, are provincially, but improperly, designated clay: the whole of this district is cropped with turnips, which are eaten on the land. The "two clay districts are comparatively small; one is in the southern part of the county, adjoining Middlesex, and the soil is stiff, hard, and tenacious, being the same as the bean lands of the north of that county: the other, which is by far the larger of the two, lies on the eastern side of the county, and nearly resembles the contiguous clay lands of Essex, being rather a strong wet loam on a stiff basis of clay marl. Both these tracts are in a great measure free from stone and flint: conjointly they include ninety thousand two hundred and forty acres; the southern tract, by the use of London manure, has been converted into very rich hay ground. The chalk district extends along the whole border of the northern part of the county, and comprehends forty-six thousand seven hundred and twenty acres; this soil is of two kinds, chalk, unmixed with any thing but what ages of cultivation have added; and what is provincially called marme, being a white marl formed by the mixture of a portion of clay; "both these soils are fruitful, but the last-mentioned is the best. The gravel tract lies in the south-eastern part of the county, around Hatfield, North Mimms, and Northall, and contains seventeen thousand two hundred and eighty acres; this soil is characterised by wetness, from many springs, most of which are impregnated with sulphur; it abounds with smooth blue pebbles, which, at various depths, and in some places close to the surface, are conglomerated by sulphureous clay into plum-pudding-stones; and the whole district, excepting only some patches of fine loam, which occur more especially on the banks of many of the smaller streams, is among the most unproductive land in the south of England. The substratum of the whole of Hertfordshire is chalk; for obtaining which, pits are sunk all over the county, its use as manure being general throughout its limits; for this purpose, the chalk which lies farthest beneath the surface soil is esteemed the best. By far the greater part of the county is under tillage; Upon all the turnip land the rotation of crops is, turnips, barley, clover, the first crop mown, the second eaten off, and wheat; some farmers adding oats; on the other soils various systems are practised. Of wheat, the turnip soils produce on an average from seventeen to twenty bxishels per acre; the strong land about twenty-five; on the fine rich loams of Buntingford, forty bushels are by no means an uncommon crop; while the average produce of this grain thoughout the county is estimated at twenty-three bushels per acre: the general average produce of barley and oats is about thirty-two bushels per acre. The artificial grasses are, clover (which has probably been cultivated in this county longer than in any other part of the kingdom,- and from the vicinity of the metropolis yields a greater profit here than elsewhere), trefoil, sainfoin, and lucerne; the culture of tares is general throughout the county. Besides the chalk already mentioned, and the manures common to other counties, soot and night-soil brought from, London, are found very beneficial on the land; about Lilley, peat-ashes are brought as manure from Bedfordshire, where they are burned in heaps, and sold at Tingrith, Flitwick, and Flitton. The grass land is. in a great measure confined to a narrow border on the south side of the county, in the vicinity of Barnet, which, being near London, is made productive by means of the manures brought from that city; with this exception, the only grass lands are those belonging to the numerous gentlemen's seats, and those in the flat bottoms of the vales which are watered by rivers; of the last-mentioned, some of the principal are on the Stort, from Hockerill to Hertford, and thence to Hatffeld, on the banks of the same river. In the parishes of the south - western corner of the county are many orchards, rarely exceeding four or five acres in extent, principally of apples and cherries; the former are the most profitable; of the latter, the caroon and the small black cherry are the favourite sorts, and a full grown tree, in a favourable season, will produce six hundred pounds weight. In consequence of so much of Hertfordshire being arable land, and the quantity of clovercarried to London being so great, live stock is an object of inferior consideration: the cattle are of various sorts; the sheep are chiefly of the South-down and Wiltshire breeds; there are also some of the new Leicester: the hogs are of different kinds. The quantity of waste lands, compared with those of most other counties, is very inconsiderable; they consist of small commons scattered over the county, the principal being near Berkhampstead. There are large tracts of coppice wood lying to the south of Hertford, in the direction of London; in the tract between Hockerill, Ware, and Buntingford, are also coppice woods; and the Marquis of Salisbury has one thousand five hundred acres. There is much fine flourishing timber about the different seats of the nobility and gentry, such as oak, ash, elm, beech, Spanish chesnut, cedar, larch, spruce, silver fir, Scotch fir, &c.; much of that in Moor park is of great antiquity. The women and children about Stevenage, Hatfieldi Redbourn, St. Alban's, Berkhampstead, Hitchin, &c., are much employed in making straw-plat. The manufacture of black lace has been carried on at Berkhampstead time immemorially, but has of late given place to that of straw-plat. The principal rivers are the Lea and the Colnej formed by the junction of many minor streams, which rise chiefly within the bounds of the county. The Lea rises in Bedfordshire, enters Hertfordshire near Bower heath, and traverses the county in a direction nearly from north-west to south-east, passing the town of Hertford, from which place it has been made navigable to its conflux with the Stort, about a mile east of Hoddesdon, where it takes a southerly course, becoming the bounT dary of the county on the east, and continuing so until it reaches the border of Middlesex. The Colne rises near Kitt's-end in Middlesex, and running by North Minims, Watford, and Rickmansworth, it soon after quits the county for Buckinghamshire. The Stort, rising in Essex, becomes navigable at Bishop's Stortford, from which place to its junction with the river Lea it forms the boundary between Essex and Hertfordshire. The Mimram rises near Frogmore, in Hitchin and Pirton hundred, and, with the Beane, which rises near Cromer in Odsey hundred, joins the Lea near Hertford. The sources of the Rib are near Buntingford, in Edwinstree hundred, and it joins the Lea between Hertford and Ware. The source of the Ash, is also in Edwinstree hundred, near Upperwick, and it falls into the Lea about a mile below Ware. The Verulam, Verlam, or Muse river, rises in Dacorum hundred, near Market-street, and on the confines of Bedfordshire, and runs in a south-south-easterly direction to St. Alban's, and thence nearly south until it joins the Colne, then only a small stream. The Gade rises also in Dacorum hundred, near Gaddesden, on the borders of Buckinghamshire, and runs in a direction nearly south, to its conflux with the Colne near Rickmansworth. At Ashwell, in this county, are the nine sister springs of the Cam, which flows by Cambridge. The Grand Junction canal, from Branston wharf on the Coventry canal to Old Brentford, where it opens into the Thames, enters Hertfordshire above Tring, and follows the course of the Bulburn and Gade rivers to Rickmansworth, and from that place the course of the Colne until it leaves the county. An act of parliament was obtained for the construction of another canal from St. Alban's to the Grand Junction canal, belov? Cashiobury park; but the proposed subscription of £17,000 failing, the design was abandoned. The road from London to Oxford, through Aylesbury, enters Hertfordshire at Bushey Heath, and passing through Watford, Berkhampstead, and.Tring, quits the county about hall a mile beyond the last place. The road from London to Berwick upon Tweed, through York, after passing through a corner of the county which surrounds East Barnet, re-enters it on Hatfield chase, and passing through Hatfield, Welwyn, andBaldock, enters Bedford: shire about two miles beyond the latter town. The road from London to Holyhead, through Chester, after passing through the same corner and through Chipping-Barnet, re-enters Hertfordshire immediately beyond South Minims, and passing through St. Alban's and Redbourn, quits the county about a mile before it reaches Dunstable. This line is also part of the road from London to Chester, through Birmingham; of that from London to Carlisle, through Warrington and Lancaster; of that from London to Manchester, through Northampton and Derby 5 of that from London to Whitehaven, through Sheffield, Settle, and Kirkby-Lonsdale; and of that from London to Manchester and Clitheroe, through Leek, Uttoxeter, and Hinckley. The road from London to Halifax and Clitheroe, through Bedford, Nottingham, and Rotherham, branches off from the last-mentioned road at St. Alban's, and passing through Harpenden, quits the county about two miles before it" reaches Luton. The road from London to Scarborough, through the counties of Huntingdon and Lincoln, enters Hertfordshire near Waltham-Cross, and passing through Cheshunt, Ware, Puckeridge, and Buntingford, enters Cambridgeshire at Royston. The road from London to Lynn-Regis, through Cambridge, branches off from the last mentioned road at Puckeridge, and passing through Barkway and Barley, enters Cambridgeshire about a mile beyond the latter place. The road from London to Norwich, through Newmarket, enters Hertfordshire from Essex, where it crosses the river Stort, at Harlow Mills, and passing through Sawbridgeworth and Bishop's Stortford, again crosses that river into Essex near the latter place: this is also the road from London to Lynn-Regis, through Brandon and Newmarket. The British Watling-street, entering Hertfordshire on the south, passed to St. Alban's, and thence along the line of the present great Irish road, to Dun'stable. The Ermin-street, passing near Enfield, entered the south-eastern border of Hertfordshire near Little Hockgate, and passed between Standon and Puckeridge, near Braughin, and through Buntingford to Royston, where it crossed the Iknield-street. The line of the Iknieldstreet, entering the north-eastern border of the county at Royston, passes through Baldock, and after crossing a small part of Bedfordshire and of Buckinghamshire, re-enters Hertfordshire for a short distance, running a little to the right of Tring. The only Roman station in this county, the situation of which has been precisely ascertained; is the celebrated one of Verulam, contiguous to St. Alban's. Excepting the ancient British roads abovementioned, which appear to have been used and improved by the Romans, the only Roman road (of the many which it is probable once intersected this county) that can now be traced with any degree of distinctness within its limits, is that which connected Verulam with the station at Chesterfield, near Sandy, on the banks of the Ivel, which runs in the line of the present great north road, through Stevenage, Graveley, and Baldock. Before the Reformation there were in this county, according to Tanner, thirty-four religious houses and hospitals. The principal ecclesiastical antiquities are St. Alban's abbey church and gate-house. At Waltham-Cross is the well known cross, erected, with several others, by Edward I., to perpetuate the remembrance of those places at which the body of his consort, Queen Eleanor, rested, in its way from Herdeby, in Lincolnshire, for interment in Westminster abbey. There are some remains of the ancient castles of Hertford, Bishop's Stortford, and Berkhampstead; and Hatfield house is a fine specimen of the style of domestic architecture which prevailed in the reign of James I. On the east side of the village of Great Amwell, at the foot of the steep bank upon which the church is situated, rises a considerable spring, which, together with that of Chadwell, feeds the canal commonly called the New River, commenced in 1609, under the powers of an act of parliament, by Mr. (afterwards Sir) Hugh Myddelton, for supplying the northern side of the metropolis with water, and completed in 1613, its length being nearly thirtynine miles; about half its course is within the eastern border of this county, and near the line of the road from London to Ware.
