There are no igneous rocks, nor any of those classed as primary, but, beginning with the Rhætic beds, we find every division of the secondary formations, with the possible exception of the Lower Greensand, represented, and in the south-eastern part of the district several of the tertiary beds may be met with on the surface.

The dip of the strata is generally towards the east; hence the earlier formations are found in the west. Nowhere else in England could a traveller in a journey of a little under fifty miles—which is about the distance from Lyme to the eastern boundary of Dorset—cross the outcrop of so many strata. A glance at a geological map of England will show that the Lias, starting from Lyme Regis, sweeps along a curve slightly concave towards the west, almost due north, until it reaches the sea again at Redcar, while the southern boundary of the chalk starting within about ten miles of Lyme runs out eastward to Beechy Head. Hence it is seen that the outcrops of the various strata are wider the further away they are from Lyme Regis.

Dorset has given names to three well-known formations and to one less well known: (1) The Portland beds, first quarried for building stone about 1660; (2) the Purbeck beds, which supplied the Early English church builders with marble for their ornamental shafts; (3) Kimmeridge clay; and (4) the Punfield beds.

The great variety of the formation coming to the surface in the area under consideration has given a striking variety to the character of the landscape: the chalk downs of the North and centre, with their rounded outlines; the abrupt escarpments of the greensand in the neighbourhood of Shaftesbury; the rich grazing land of Blackmore Vale on the Oxford clay; and the great Heath (Mr. Hardy’s Egdon) stretching from near Dorchester out to the east across Woolwich, Reading, and Bagshot beds, with their layers of gravel, sand, and clay. The chalk heights are destitute of water; the streams and rivers are those of the level valleys and plains of Oolitic clays—hence they are slow and shallow, and are not navigable, even by small craft, far from their mouths.

The only sides from which in early days invaders were likely to come were the south and east; and both of these boundaries were well protected by natural defences, the former by its wall of cliffs and the deadly line of the Chesil beach. The only opening in the wall was Poole Harbour, a land-locked bay, across which small craft might indeed be rowed, but whose shores were no doubt a swamp entangled by vegetation. Swanage Bay and Lulworth Cove could have been easily defended. Weymouth Bay was the most vulnerable point. Dense forests protected the eastern boundary. These natural defences had a marked effect, as we shall see, on the history of the people. Dorset for many centuries was an isolated district, and is so to a certain extent now, though great changes have taken place during the last fifty or sixty years, due to the two railways that carry passengers from the East to Weymouth and the one that brings them from the North to Poole and on to Bournemouth. This isolation has conduced to the survival not only of old modes of speech, but also of old customs, modes of thought, and superstitions.

It may be well, before speaking of this history, to state that the county with which this volume deals should always be spoken of as “Dorset,” never as “Dorsetshire”; for in no sense of the word is Dorset a shire, as will be explained further on.

We find within the boundaries of the district very few traces of Palæolithic man: the earliest inhabitants, who have left well-marked memorials of themselves, were Iberians, a non-Aryan race, still represented by the Basques of the Pyrenees and by certain inhabitants of Wales. They were short of stature, swarthy of skin, dark of hair, long-skulled. Their characteristic weapon or implement was a stone axe, ground, not chipped, to a sharp edge; they buried their dead in a crouching attitude in the long barrows which are still to be seen in certain parts of Dorset, chiefly to the north-east of the Stour Valley. When and how they came into Britain we cannot tell for certain; it was undoubtedly after the glacial epoch, and probably at a time when the Straits of Dover had not come into being and the Thames was still a tributary of the Rhine. They were in what is known as the Neolithic stage of civilisation; but in course of time, after this country had become an island, invaders broke in upon them, Aryans of the Celtic race, probably (as Professor Rhys thinks, though he says he is not certain on this point) of the Goidelic branch. These men were tall, fair-haired, blue-eyed, round-skulled, and were in a more advanced stage of civilisation than the Iberians, using bronze weapons, and burying their dead, sometimes after cremation, in the round barrows that exist in such large numbers on the Dorset downs. Their better arms and greater strength told in the warfare that ensued: whether the earlier inhabitants were altogether destroyed, or expelled or lived on in diminished numbers in a state of slavery, we have no means of ascertaining. But certain it is that the Celts became masters of the land. These men were some of those who are called in school history books “Ancient Britons”; the Wessex folk in after days called them “Welsh”—that is, “foreigners”—the word that in their language answered to βάρβαροι and “barbari” of the Greeks and Romans. What they called themselves we do not know. Ptolemy speaks of them as “Durotriges,” the name by which they were known to the Romans. Despite various conjectures, the etymology of this word is uncertain. The land which they inhabited was, as already pointed out, much isolated. The lofty cliffs from the entrance to Poole Harbour to Portland formed a natural defence; beyond this, the long line of the Chesil beach, and further west, more cliffs right on to the mouth of the Axe. Most of the lowlands of the interior were occupied by impenetrable forests, and the slow-running rivers, which even now in rainy seasons overflow their banks, and must then, when the rainfall was much heavier than now, have spread out into swamps, rendered unnavigable by their thick tangle of vegetation. The inhabitants dwelt on the sloping sides of the downs, getting the water they needed from the valleys, and retiring for safety to the almost innumerable encampments that crowned the crests of the hills, many of which remain easily to be distinguished to this day. Nowhere else in England in an equal area can so many Celtic earthworks be found as in Dorset. The Romans came in due course, landing we know not where, and established themselves in certain towns not far from the coasts.

The Celts were not slain or driven out of their land, but lived on together with the Romans, gradually advancing in civilisation under Roman influence. They had already adopted the Christian religion: they belonged to the old British Church, which lived on in the south-west of England even through that period when the Teutonic invaders—Jutes, Angles, Saxons—devastated the south-east, east, north, and central parts of the island, and utterly drove westward before them the Celtic Christians into Wales and the south-west of Scotland. Dorset remained for some time untouched, for though the Romans had cleared some of the forests before them, and had cut roads through others, establishing at intervals along them military stations, and strengthening and occupying many of the Celtic camps, yet the vast forest—“Selwood,” as the English called it—defended Dorset from any attack of the West Saxons, who had settled further to the east. Once, and once only, if we venture, with Professor Freeman, to identify Badbury Rings, near Wimborne, on the Roman Road, with the Mons Badonicus of Gildas, the Saxons, under Cerdic, in 516, invaded the land of the Durotriges, coming along the Roman Road which leads from Salisbury to Dorchester, through the gap in the forest at Woodyates, but found that mighty triple ramparted stronghold held by Celtic Arthur and his knights, round whom so much that is legendary has gathered, but who probably were not altogether mythical. In the fight that followed, the Christian Celt was victorious, and the Saxon invader was driven in flight back to his own territory beyond Selwood. Some place Mons Badonicus in the very north of England, or even in Scotland, and say that the battle was fought between the Northumbrians and the North Welsh: if this view is correct, we may say that no serious attack was made on the Celts of Dorset from the east. According to Mr. Wildman’s theory, as stated in his Life of St. Ealdhelm—which theory has a great air of probability about it—the Wessex folk, under Cenwealh, son of Cynegils, the first Christian King of the West Saxons, won two victories: one at Bradford-on-Avon in 652, and one at the “Hills” in 658. Thus North Dorset was overcome, and gradually the West Saxons passed on westward through Somerset, until in 682 Centwine, according to the English Chronicle, drove the Welsh into the sea. William of Malmesbury calls them “Norht Walæs,” or North Welsh, but this is absurd: Mr. Wildman thinks “Norht” may be a mistake for “Dorn,” or “Thorn,” and that the Celts of Dorset are meant, and that the sea mentioned is the English Channel. From this time the fate of the Durotriges was sealed: their land became part of the great West Saxon kingdom. Well indeed was it for them that they had remained independent until after the time when their conquerors had ceased to worship Woden and Thunder and had given in their allegiance to the White Christ; for had these men still been worshippers of the old fierce gods, the Celts would have fared much worse. Now, instead of being exterminated, they were allowed to dwell among the West Saxon settlers, in an inferior position, but yet protected by the West Saxon laws, as we see from those of Ine who reigned over the West Saxons from 688 to 728. The Wessex settlers in Dorset were called by themselves “Dornsæte,” or “Dorsæte,” whence comes the name of Dorset. It will be seen then, that Dorset is what Professor Freeman calls a “ga”—the land in which a certain tribe settled—and differs entirely from those divisions made after the Mercian land had been won back from the Danes, when shires were formed by shearing up the newly recovered land, not into its former divisions which the Danish conquest had obliterated, but into convenient portions, each called after the name of the chief town within its borders, such as Oxfordshire from Oxford, Leicestershire from Leicester. The Danes did for a time get possession of the larger part of Wessex, but it was only for a time: the boundaries of Dorset were not wiped out, and there was no need to make any fresh division. So when we use the name Dorset for the county we use the very name that it was known by in the seventh century. It is also interesting to observe that Dorset has been Christian from the days of the conversion of the Roman Empire, that no altars smoked on Dorset soil to Woden, no temples were built in honour of Thunder, no prayers were offered to Freya; but it is also worth notice that the Celtic Christian Church was not ready to amalgamate with the Wessex Church, which had derived its Christianity from Papal Rome. However, the Church of the Conquerors prevailed, and Dorset became not only part of the West Saxon kingdom, but also of the West Saxon diocese, under the supervision of a bishop, who at first had his bishop-stool at Dorchester, not the Dorset town, but one of the same name on the Thames, not far from Abingdon. In 705, when Ine was King, it received a bishop of its own in the person of St. Ealdhelm, Abbot of Malmesbury, who on his appointment placed his bishop-stool at Sherborne: he did not live to hold this office long, for he died in 709. But a line of twenty-five bishops ruled at Sherborne, the last of whom—Herman, a Fleming brought over by Eadward the Confessor—transferred his see in 1075 to Old Sarum, as it is now called; whereupon the church of Sherborne lost its cathedral rank.

The southern part of Dorset, especially in the neighbourhood of Poole Harbour, suffered much during the time that the Danes were harrying the coast of England. There were fights at sea in Swanage Bay, there were fights on land round the walls of Wareham, there were burnings of religious houses at Wimborne and Wareham. Then followed the victories of Ælfred, and for a time Dorset had rest. But after Eadward was murdered at “Corfes-geat” by his stepmother Ælfthryth’s order, and the weak King Æthelred was crowned, the Danes gave trouble again. The King first bribed them to land alone; and afterwards, when, trusting to a treaty he had made with them, many Danes had settled peacefully in the country, he gave orders for a general massacre—men, women and children—on St. Brice’s Day (November 13th), 1002. Among those who perished was a sister of Swegen, the Danish King, Christian though she was. This treacherous and cruel deed brought the old Dane across the seas in hot haste to take terrible vengeance on the perpetrator of the dastardly outrage. All southern England, including Dorset, was soon ablaze with burning towns. The walls of Dorchester were demolished, the Abbey of Cerne was pillaged and destroyed, Wareham was reduced to ashes. Swegen became King, but reigned only a short time, and his greater son, Cnut, succeeded him. When he had been recognised as King by the English, and had got rid of all probable rivals, he governed well and justly, and the land had rest. Dorset had peace until Harold had fallen on the hill of Battle, and the south-eastern and southern parts of England had acknowledged William as King. The men of the west still remained independent, Exeter being the chief city to assert its independence. In 1088 William resolved to set about to subdue these western rebels, as he called them. He demanded that they should accept him as King, take oaths of allegiance to him, and receive him within their walls. To this the men of Exeter made answer that they would pay tribute to him as overlord of England as they had paid to the previous King, but that they would not take oaths of allegiance, nor would they allow him to enter the city. William’s answer was an immediate march westward. Professor Freeman says that there is no record of the details of his march; but naturally it would lie through Dorset, the towns of which were in sympathy with Exeter. Knowing what harsh and cruel things William could do when it suited his purpose, we cannot for a moment doubt that he fearfully harried all the Dorset towns on the line of his march, seeking by severity to them to overawe the city of Exeter.

In the wars between Stephen and Maud, Dorset was often the battle-ground of the rival claimants for the throne. Wareham, unfortunate then, as usual, was taken and re-taken more than once, first by one party, then by the other; but lack of space prevents the telling of this piece of local history.
