It is generally conceded that both the science and art of forestry are most thoroughly developed and most intensively applied throughout Germany. It must, however, not be understood that perfection has been reached anywhere in the practical application of the art, or that the science, which like that of medicine has been largely a growth of empiricism, is in all parts safely based; nor are definitely settled forest policies so entrenched, that they have become immutable. On the contrary, there are still mismanaged and unmanaged woods to be found, mainly those in the hands of farmers and other private owners; there are still even in well managed forests practices pursued which are known not to conform to theoretical ideals, and others which lack a sure scientific foundation; and while the general policy of conservative management and of State interest in the same is thoroughly established, the methods of attaining the result are neither uniform throughout the various States which form the German Federation, nor positively settled anywhere. In other words, the history of forestry is still, even in this most advanced country, in the stage of lively development. For the student of forestry the history of its development in Germany is of greatest interest not only because his art has reached here the highest and most intensive application, but because all the phases of development through which other countries have passed or else will eventually have to pass are here exemplified, and many if not most of the other countries of the world have more or less followed German example or have been at least influenced by German precedent. There is hardly a policy or practice that has not at some time in some part been employed in the fatherland of forestry. One reason for this rich historical background is the fact, that Germany has never been a unit, that from its earliest history it was broken up into many independent and, until modern times, only loosely associated units, which developed differently in social, political and economic direction. This accounts also for the great variety of conditions existing even to-day in the 26 principalities which form the German empire. Politically, it may be mentioned that out of the very many independent principalities into which the German territory had been divided, variable in number from time to time, the 26 which had preserved their autonomy formed in 1871 the federation of States, known as the German Empire. Each of these has its own representative government including the forest administration, very much like the state governments of the United States; only the army and navy, tariff, posts, telegraphs, criminal law and foreign policy, and a few other matters are under the direct jurisdiction of the empire, represented in the Reichstag, the Bundesrath, and the Emperor.
