of the sea moderates the extremes of heat and cold; the sea is occasionally frozen at Varna. The coast-line is exposed to violent north-east winds, and the Black Sea, the [Greek: pontos axeinos] or "inhospitable sea" of the Greeks, maintains its evil reputation for storms. The sheltered plain of Eastern Rumelia possesses a comparatively warm climate; spring begins six weeks earlier than elsewhere in Bulgaria, and the vegetation is that of southern Europe. In general the Bulgarian winter is short and severe; the spring short, changeable and rainy; the summer hot, but tempered by thunderstorms; the autumn (yasen, "the clear time") magnificently fine and sometimes prolonged into the month of December. The mean temperature is 52��. The climate is healthy, especially in the mountainous districts. Malarial fever prevails in the valley of the Maritza, in the low-lying regions of the Black Sea coast, and even in the upland plain of Sofia, owing to neglect of drainage. The mean annual rainfall is 25-59 in. (Gabrovo, 41-73; Sofia, 27-68; Varna, 18-50).
Fauna.--Few special features are noticeable in the Bulgarian fauna. Bears are still abundant in the higher mountain districts, especially in the Rilska Planina and Rhodope; the Bulgarian bear is small and of brown colour, like that of the Carpathians. Wolves are very numerous, and in winter commit great depredations even in the larger country towns and villages; in hard weather they have been known to approach the outskirts of Sofia. The government offers a reward for the destruction of both these animals. The roe deer is found in all the forests, the red deer is less common; the chamois haunts the higher regions of the Rilska Planina, Rhodope and the Balkans. The jackal (Canis aureus) appears in the district of Burgas; the lynx is said to exist in the Sredna Gora; the wild boar, otter, fox, badger, hare, wild cat, marten, polecat (Foetorius putorius; the rare tiger polecat, Foetorius sarmaticus, is also found), weasel and shrewmouse (Spermophilus citillus) are common. The beaver (Bulg. bebr) appears to have been abundant in certain localities, e.g. Bebrovo, Bebresh, &c., but it is now apparently extinct. Snakes (Coluber natrix and other species), vipers (Vipera berus and V. ammodytes), and land and water tortoises are numerous. The domestic animals are the same as in the other countries of southeastern Europe; the fierce shaggy grey sheep-dog leaves a lasting impression on most travellers in the interior. Fowls, especially turkeys, are everywhere abundant, and great numbers of geese may be seen in the Moslem villages. The ornithology of Bulgaria is especially interesting. Eagles (Aquila imperialis and the rarer Aquila fulva), vultures (Vultur monachus, Gyps fulvus, Neophron percnopterus), owls, kites, and the smaller birds of prey are extraordinarily abundant; singing birds are consequently rare. The lammergeier (Gypa?tus barbatus) is not uncommon. Immense flocks of wild swans, geese, pelicans, herons and other waterfowl haunt the Danube and the lagoons of the Black Sea coast. The cock of the woods (Tetrao urogallus) is found in the Balkan and Rhodope forests, the wild pheasant in the Tunja valley, the bustard (Otis tarda) in the Eastern Rumelian plain. Among the migratory birds are the crane, which hibernates in the Maritza valley, woodcock, snipe and quail; the great spotted cuckoo (Coccystes glandarius) is an occasional visitant. The red starling (Pastor roseus) sometimes appears in large flights. The stork, which is never molested, adds a picturesque feature to the Bulgarian village. Of fresh-water fish, the sturgeon (Acipenser sturio and A. huso), sterlet, salmon (Salmo hucho), and carp are found in the Danube; the mountain streams abound in trout. The Black Sea supplies turbot, mackerel, &c.; dolphins and flying fish may sometimes be seen.
Flora.--In regard to its flora the country may be divided into (1) the northern plain sloping from the Balkans to the Danube, (2) the southern plain between the Balkans and Rhodope, (3) the districts adjoining the Black Sea, (4) the elevated basins of Sofia, Samakov and Kiustendil, (5) the Alpine and sub-Alpine regions of the Balkans and the southern mountain group. In the first-mentioned region the vegetation resembles that of the Russian and Rumanian steppes; in the spring the country is adorned with the flowers of the crocus, orchis, iris, tulip and other bulbous plants, which in summer give way to tall grasses, umbelliferous growths, dianthi, astragali, &c. In the more sheltered district south of the Balkans the richer vegetation recalls that of the neighbourhood of Constantinople and the adjacent parts of Asia Minor. On the Black Sea coast many types of the Crimean, Transcaucasian and even the Mediterranean flora present themselves. The plateaus of Sofia and Samakov furnish specimens of sub-alpine plants, while the vine disappears; the hollow of Kiustendil, owing to its southerly aspect, affords the vegetation of the Macedonian valleys. The flora of the Balkans corresponds with that of the Carpathians;
