The Heath Association educates its own officers, including in their subjects the management of meadows and peatbogs. A Forestry Association, composed one-half of forest owners, with its organ _Tidskrift for Skovvaesen_, in existence since 1888, and a valuable book literature, in which the problems of the heath are especially fully and authoritatively treated, places Denmark in the foremost rank in the forestry world in these particulars. Among the prominent contributors are to be mentioned, besides Reventlow and Dalgas, _P. E. Müller_, well known by his discussions of the problems of moor soils. From 1876 to 1891, he issued a magazine, in which _Oppermann_ contributed a history of Danish forestry. The latter author also, in co-operation with _Hauch_, published in 1900 a Hand-book of Forestry. THE MEDITERRANEAN PENINSULAS. Geographically, and to some extent climatically, the three peninsulas of the Mediterranean Sea, the Iberian, Italian, and the Balkan, are situated alike. Their people, if not in race, are in temper and characteristics, and in their political economy more or less alike. They represent the oldest civilization in Europe, and in their long history have been frequently in collision with each other. Their forests, through centuries of abuse, are wherever accessible, in poorest condition. Long-continued political disturbances, which have prevented peaceful development, and poverty, have been the greatest hindrances to economic reforms like the recuperation of forests, which require sacrifices. Ancient rights of user, and the necessity of politicians to respect them are also responsible for the fact that, while praiseworthy attempts in legislation have been made, execution has been usually lagging behind. The accessibility to sea, permitting readily importation, the temperate climate, the simple life and abstemiousness of the people, and the lack of industrial development have made the deficiency of wood material less felt than it would otherwise be, but the detrimental influence of forest destruction is being repeatedly experienced in floods and drouths. There is probably no more potent cause of forest devastation in all this section of the world than the pasturing of the woods, especially with sheep and goats. While Italy is now a united country, and only two peoples, Spain and Portugal, occupy the Iberian peninsula, the Balkan peninsula is occupied by eight separate peoples, if we include all the country south of the Danube River and East of the Carpathian Mountains.
