It is generally believed by naturalists that the ancestors of most of our fauna and flora reached this country at a time when what we now call the British Isles formed part of the mainland of Europe, and when there was no intervening sea to bar the way. Before this colonisation was complete, however—that is, before all the different kinds of European beasts and birds had made their way to the extreme western districts—communication with the continent was broken off. The land of the north-western districts of Europe sank. The sea flowed in, forming the German Ocean, the English Channel and the Irish Sea, and the influx of animal life was stopped. This is the reason why there are more than twice as many kinds of land animals in Germany as there are in England, and nearly twice as many in England as there are in Ireland. This is the reason why there are no snakes in Ireland, and why the nightingale, on returning from the south, never crosses into the sister kingdom. On islands that have long been separated from a continent it is found that forms of life tend to vary in the lapse of time, and that fresh species are developed. That it is not long, as geological periods go, since Great Britain became an island, is shown by the fact that we have no quadruped or reptile except the Irish weasel (Mustela hibernica), and, setting aside minor differences which some writers have magnified to the value of a species, only one Some of the animals which came from Europe into Britain have died out, either because the climate changed and so cut off their food supply, or because they were destroyed by the hunters of the Stone Age. The bones which have been found in Kent's Cavern at Torquay, and in other caverns, afford clear evidence that the mammoth, the lion, the bear, and the hyaena once roamed over the hills of Devonshire. Although there are many more species of beasts and birds on the continent of Europe than there are in this country, both birds and beasts are numerically much more common here. Nothing strikes a naturalist more forcibly when travelling in France or Italy, for example, than the scarcity of wild life, and especially the fewness of the birds. It is true that we have fewer species, but we have many more individuals. To this, several causes have contributed. Englishmen do not, as is the custom in many European countries, shoot or trap for food small birds of every description. And game preserving—although it has been fatal to the larger birds of prey, such as kites, falcons, and buzzards, and keeps down other species, such as jays, magpies, and carrion crows—provides innumerable sanctuaries for great numbers of the smaller birds, which are safe from harm during the breeding season. The natural features of Devonshire are so varied in character, including as they do large areas of wild and uncultivated and thinly-inhabited country, together with many well-wooded and sequestered valleys, and wide stretches of bog, salt-marsh, and sea-coast, that it is very rich in both animal and vegetable life. Its marine fauna and flora, in particular, are of very great interest, and are among the most remarkable in England. Nearly all the native mammals of the British Isles are found or have been found in this county, from the "tall red deer" that has run wild on Exmoor from time immemorial, down to the pygmy shrew, the smallest but one of European quadrupeds, and weighing only one-tenth of an ounce, or about forty-three grains and a half. Among the eight species of Devonshire bats is the very rare particoloured bat (Vesperugo discolor), of which the only example ever recorded in England was taken at Plymouth, having perhaps travelled there in the rigging of a ship. It is probably more than a hundred years since the last genuine wild-cat was seen in the county, but both the marten and the polecat still survive in secluded spots. Foxes are common, and there are still many badgers in some of the Among the many marine mammalia that have been recorded for the county are two kinds of seal, the sperm-whale, the common rorqual—of which specimens nearly 70 feet long have been brought into Plymouth—the rare bottle-nosed dolphin and the still rarer Risso's grampus. Bones of a whale called Balaenoptera robustus, which were once washed ashore in Torbay, are said to represent a species so rare that these and a few similar relics stranded in Sweden are the only remains of it that have ever been found. Situated as Devonshire is, between the English and the Bristol Channels, and containing widely-different physical features, suited to the needs of species of very different habits, the list of its birds, including residents, migrants, occasional visitors, and stragglers from the Atlantic and even from America, is a very long one. Among the larger land-birds which still hold their ground in the county are the raven and buzzard, both of which are to be seen on Exmoor and Dartmoor and on the coast, and the peregrine falcon, which has eyries on both the northern and southern seaboards. A few pairs of choughs still build in the northern cliffs; while such But by far the most abundant, and perhaps the most characteristic, of the birds of Devonshire are the sea-fowl, the water-fowl, and the waders, of which more than 140 different kinds have been recorded for the county. Not only are its sandy shores, its bays and estuaries and leys, There is, however, nothing on the mainland of Devonshire to compare in ornithological interest with Lundy, which in the summer time is a bird-lover's paradise. Gannets, once very numerous, have now left the island, but cormorants, shags and gulls of various species here build their untidy nests. Here multitudes of guillemots and razorbills assemble in the spring and lay their great pear-shaped and boldly-marked eggs on the ledges of the cliffs; while even vaster hosts of puffins come back every year to take up their quarters in rabbit-burrows or in holes which they have dug for themselves in the turf. Here the raven, the buzzard, and the peregrine have fastnesses. Here, in chinks and crannies, storm-petrels breed; and here, when darkness falls, the startled listener may hear the weird, wailing cry of the night-wandering shearwaters. The few reptiles and batrachians of Devonshire present no points of special interest. Vipers abound on Dartmoor, where they are commoner than grass-snakes. The freshwater fish differ little from those found in the neighbouring counties; but there are fewer kinds in Devonshire than there are in the midlands or in the east of England. Trout abound in all the streams, and there are important salmon-fisheries on the Exe, the Dart, and other rivers. A sturgeon seven-and-a-half feet long was once taken in the Exe. Eels, which are hatched in the Atlantic, to the west and north of the British Islands, at a depth of 3000 feet or more, come up from the sea when they are two years old, and still very small, and ascend the rivers, especially Exe, in enormous numbers. When they are mature, which is not until they are several years old, they go down to the sea to spawn, and never return. It is, however, in marine zoology, for which few other parts of England afford so rich a field, and for which its bays and inlets, its rock-pools and stretches of sand provide ideal hunting-ground for the naturalist, that Devonshire is most distinguished. Many famous zoologists, such as Leach, Montagu, Parfitt, Gosse, and Kingsley have won renown both for themselves and for the county by their researches; while the Marine Biological Laboratory at Plymouth is constantly adding to our knowledge of the multitudinous inhabitants of the sea. The subject is so vast that only a few chief points can here be touched upon. The sea-fish differ in marked degree from those of the Rich as are the Devonshire seas in fish, they are richer still in crustaceans—crabs, lobsters, prawns, shrimps and their allies; and in this respect ours is the premier Other and very beautiful forms of marine life, such as starfish, anemones, corals and other zoophytes, and sea-shells are very abundant. And in spite of the comparative scarcity of lime in the soil of Devonshire, the list of land and freshwater shells is a long one. It is remarkable that Limnaea stagnalis and Planorbis corneus, two water-shells that are common in Somerset, are unknown in Devon. The pearl-bearing mussel, Unio margaritifer, is found in both the Taw and the Teign. The county is rich in insects, especially as regards butterflies, moths, and beetles; but several of the first-named which have been caught in Somerset have not been recorded here. The black-veined white (Pieris crataegi), once a common insect, has disappeared within the last forty years, and the greasy fritillary (Melitaea Artemis)—another vanishing species—is now almost extinct. Neither As in the case of birds, the county is, from its position, a favourite alighting-place for insects coming from abroad. Between 1876 and 1890 large numbers of a very striking and beautiful American butterfly, Danais plexippus, appeared in England, having apparently crossed the Atlantic, and three specimens were caught in Devonshire. The Lulworth skipper (Hesperia Actaeon), a small butterfly which elsewhere is only found in Dorset, occurs along the south-east coast of this county. Moths are very abundant, and the first recorded British examples of several species were taken in Devonshire. About a hundred years ago, caterpillars of the spurge As might be expected in a district of such varied physical features, with so mild a climate and such an ample rainfall, the flowering plants of Devonshire are very numerous, no fewer than 1156 species having been recorded. The abundance and beauty of its wild-flowers is one of the characteristics of the county. No one who has ever seen them will forget the wonderful wealth of primroses in some of the river valleys—at Holne, for example—or the splendour of the ling-empurpled sweeps of Dartmoor, or its sheets of golden gorse; or the marvellous mist of bluebells upon woodland slopes or in the shelter of straggling hedgerows. Each several district, sea-shore and salt-marsh, moor and bog, wood and valley, has its own distinct and characteristic flora. One Devonshire plant, the Romulea or gÊnotte, Romulea columnae, a Mediterranean species with very small pale blue flowers, is abundant on the Warren at the mouth of the Exe, but grows nowhere else in England, although it is found in Guernsey. Several plants occur in only one other English Ferns are characteristic of Devonshire. Not only are most of the familiar kinds abundant, but rarer species as the true maiden-hair, two filmy ferns, and the parsley fern (Cryptogramme crispa) are to be found. The magnificent royal fern, Osmunda regalis, still grows in some of the river valleys, and especially in Holne Chase, but it has suffered much from the greed of collectors, and the raids of unscrupulous dealers. A great variety of spleenworts has been recorded for the county, and one of the characteristic hedgerow ferns is the pretty little Asplenium adiantum-nigrum. Mosses, also, are very abundant, and there is one kind which occurs nowhere else in Britain. In sea-weeds Devonshire is richer than any other county except Dorset. Among its 468 different species is the Sargasso or Gulf-weed, sprays of which are sometimes thrown ashore after rough weather. Except on the moors Devonshire is well timbered. The elm is perhaps the most conspicuous tree, but the beech and the ash are also very abundant. There is a A good many places in Devonshire take their names |
