INTRODUCTION

I. SITUATION, EXTENT AND BOUNDARIES

Hertfordshire, or Herts, is a county in the S.E. of England. On the S. it is bounded by Middlesex; on the S.W. by Buckinghamshire; on the N.W. by Bedfordshire; on the N. by Cambridgeshire; on the E. by Essex. Its extreme measurement from due E. to W., say from Little Hyde Hall to Puttenham, is about 38 miles; from N. to S., from Mobb's Hole at the top of Ashwell Common to a point just S. of Totteridge Green, about 30 miles; but a longer line, 36 miles in length, may be drawn from Mobb's Hole to Troy Farm in the S.W. Its boundaries are very irregular; the neighbourhood of Long Marston is almost surrounded by Buckinghamshire and Bedfordshire, that of Hinxworth by Cambridgeshire and Bedfordshire, and that of Barnet by Middlesex. Its extreme points are:--

N. Lat. 52 deg. 5' (N.) E. Long. 0 deg. 13' (E.) W. Long. 0 deg. 45' (W.) S. Lat. 51 deg. 36' (N.)

Its area is 404,523 acres or 632 square miles. It is one of the smallest counties in England, the still smaller counties being Rutland, Middlesex, Huntingdon, Bedford and Monmouth. Hertfordshire is one of the six home counties.

II. PHYSICAL FEATURES

Hertfordshire, being an inland county, is naturally devoid of many charms to be found in those counties which have a sea-coast. But it has beauties of its own, being particularly varied and undulating. Its scenery is pleasantly diversified by many woods, which however are mostly of but small extent, by swelling cornfields, and by several small and winding streams. There is much rich loam in the many little valley-bottoms traversed by these streams, and other loams of inferior quality are found in abundance on the higher levels of the arable districts. The soil in many parts, owing to the preponderance of chalk, is specially adapted to the cultivation of wheat. Its trees have elicited the admiration of many, particularly its oaks and elms, of which colossal specimens are found here and there throughout the county, and its beeches, of which the beautiful woods on the Chiltern slopes and elsewhere in the W. are largely composed. The hornbeam is almost restricted to Essex and Hertfordshire. The woods of Hertfordshire form indeed its sweetest attraction in the eyes of many. The districts of Rickmansworth, Radlett, Wheathampstead and Breachwood Green, among others, are dotted with coppices of ideal loveliness, and larger woods such as Batch Wood near St. Albans and Bricket Wood near Watford are carpeted with flowers in their season, interspersed with glades, and haunted by jays and doves, by ringlets and brimstones. Hazel woods abound, and parties of village children busily "a-nutting" in the autumn are one of the commonest sights of the county. It abounds, too, in quiet park-like spots which are the delight of artists, and contains many villages and hamlets picturesquely situated upon slopes and embowered among trees. A large proportion of the birds known to English observers are found in the county either regularly or as chance visitors, and will be treated more fully in a separate section. The many narrow, winding, flower-scented lanes are one of the chief beauties of Hertfordshire. The eastern part of the county, though, on the whole, less charming to the eye than the rest, contains some fine manor houses and interesting old parish churches. Its most beautiful part is unquestionably the W., near the Buckinghamshire border; its greatest historic interest centres around St. Albans, with its wonderful old abbey church now largely restored; Berkhampstead, Hertford, Hatfield and Hitchin. The county contains rather less than the average of waste or common land; the stretches of heath used for grazing purposes only aggregating 1,200 acres.

Among the finest panoramic views may be mentioned:--

There were medicinal waters at Barnet, Northaw, Hemel Hempstead and Welwyn, but these are now disused. Many other details touching physiographical characteristics are mentioned as occasion arises in the Alphabetical Gazetteer which follows this Introduction.

The Geology of Hertfordshire must be here summarised in few words. The predominant formations are the Cretaceous and the Tertiary.

CRETACEOUS.--Ignoring the Gault, which barely touches the county, this formation consists chiefly of Chalk-marl, Lower, Middle and Upper Chalk. A series of Chalk Downs, an extension of the Chiltern Hills, stretches, roughly speaking, from Tring to Royston, forming by far the most prominent natural feature of Hertfordshire. The oldest rocks are in the N.W.

The Chalk Marl is superimposed upon the Gault and Upper Greensand beds, which are confined to the western portion of the county. Its upper layer passes into a sandy limestone, known as Totternhoe stone, which has furnished materials for many churches in the shire. Ashwell, Pirton and Tring may be named as neighbourhoods where this stratum may be traced.

The Lower Chalk is devoid of flints, and rests, in somewhat steeply sloping beds, upon the Totternhoe stone. It forms the western slopes of the Dunstable Downs, and of the Chiltern Hills. It is fossiliferous, one of the commonest of its shells being the Terebratula.

The Middle Chalk, of resonant hardness, is laminated, and has at its base the Melbourn Rock and at its summit the Chalk Rock. Nodules of flint, greenish in appearance, and (rarely) arranged in layers, occur sparsely in the Middle Chalk, which may be traced in the neighbourhood of Boxmoor, Berkhampstead and Baldock, and also in a few other districts.

The Upper Chalk.--Although, as has been stated, the configuration of Hertfordshire is very undulating, we are able to discern a general trend in certain districts. Thus, there is a gradual slope to the S. from the N.W. and central hills, a slope which comprises the larger part of the county. This slope is formed of the Upper Chalk, a formation abounding in layers of black flints. The chalk is whiter than that of the lower beds, and very much softer. Fossil sponges, sea-urchins, etc., are abundant in this formation.

TERTIARY.--Many of the chalk hills of Hertfordshire are strewn with outlying more recent deposits which prove that the lower Tertiary beds were more extensive in remote ages. The beds of sand and clay, of such frequent occurrence in the S.E. districts, contain fossils so distinct from those of the Upper Chalk that an immense interval must have elapsed before those Tertiary deposits were in turn laid down.

The Eocene Formation.--The Thanet Beds, of light-coloured sands, present in some other parts of the London Basin, notably in Kent, are wanting in Hertfordshire. There are, however, some widespread deposits of loamy sands which may possibly be rearranged material from the Thanet Beds.

The lowest Eocene deposits in the county are the Reading Beds. These rest directly upon the Chalk and have an average thickness of, say, 25 feet. They may be traced E. to S.W. from the brickfields near Hertford to Hatfield Park; thence to the kilns on Watford Heath and at Bushey; they may also be traced from Watford to Harefield Park. These beds contain flints, usually found close to the Chalk, and consist chiefly of mottled clays, sands, and pebble-beds. Fossils are but rarely found. From the Woolwich and Reading Beds come those conglomerate masses of flint pebbles commonly called Hertfordshire plum-pudding stone. These have usually a silicious matrix and were often used by the Romans and others for making querns for corn-grinding. It is, perhaps, not impertinent to mention here the opinion of geologists that during the Eocene Period a considerable portion of the land usually spoken of as S.E. England was covered by the ocean.

Resting upon the Reading Beds we find that well-known stratum called the London Clay, which is of bluish hue when dug at any considerable depth. It is found in some of the same districts as the Woolwich and Reading Beds, and from Hertford and Watford it extends to N.E. and S.W. respectively until it leaves Hertfordshire. Its direction may be approximately traced by a series of hills, none of which are of any great height.

The Drift.--In Hertfordshire, as elsewhere, the strata whose names are so familiar to geologists do not form the existing surface of the ground. For the origin of this we go back to a comparatively recent period, when disintegration was busily working upon the solid rocks, and glaciers were moving southwards, leaving stones and much loose debris in their wake. Rivers, some of which, as in the Harpenden valley, have long ceased to run, separated the flints from the chalk, forming a gravel which is found in quantities at Harpenden, Wheathampstead and St. Albans, and is, indeed, present in all valley-bottoms, even where no river now runs. Gravel, together with clays, sand, and alluvial loams, forms, for the most part, the actual surface of the county.
