. Studies in French forestry . Forests and forestry. 26 FOREST REGIONS AND IMPORTANT SPECIES the depression between the Central Plateau and the eastern mountains by way of the valleys of the Rh6ne and Sa6ne, traverses the C6te d'Or hills and so gains the valley of the Seine; the other skirting the southern base of the C^vennes, reaches the ocean by way of the Garonne Valley. Another natural highway traversing the lowlands to the west of the Central Plateau unites the Seine basin with that of the Garonne. Climate. — The north and northwest of France bear a great resem- blance, both in temperature and produce, to the south of England, rain occurring frequently and the country being consequently suited for pasture. The raias are less frequent in the interior but when they do occur are much heavier, so there is much less difference in the annual raiu- fall there as compared with the rest of the country than in the number of rainy days. The annual rainfall of the whole of France averages about 32 inches; the precipitation is greatest along the Atlantic seaboard and in the elevated regions of the interior. It attains over 60 inches in the basin of the Adour (71 inches at the western extremity of the Pyrenees), and nearly as much in the Vosges, Morvan, C^vennes, and parts of the Central Plateau. The zone of level country extending from Rheims and Troyes to Angers and Poitiers with the ex- ception of the Loire Valley and the Brie, receives less than 24 inches of rain annually (Paris about 23 inches), as also does the Mediterranean coast west of Marseilles. The prevailing winds, mild and humid, are west winds from the At- lantic. Continental climatic influ- ences make themselves felt in the east wind which is frequent in winter and in the east of France, while the Mistral, a violent wind from the northwest, is characteristic of the Fig. 1 (after Jolyet).—The black areas Mediterranean region.
