The next stage is that of restriction in forest use and protection against cattle and fire, the stage of conservative lumbering. Then come positive efforts to secure re-growth by fostering natural regeneration or by artificial planting: the practice of silviculture begins. Finally a management for continuity—organizing existing forest areas for sustained yield—forest economy is introduced.
That the time and progress of these stages of development and the methods of their inauguration vary in different parts of the world is readily understood from the intimate relation which, as has been pointed out, this economic subject bears to all other economic as well as political developments.
At the present time we find all the European nations practicing forestry, although with a very varying degree of intensity. The greatest and most universal development of the art is for good reasons to be found in Germany and its nearest neighbors. Early attention to forest conservancy was here induced by density of population, which enforces intensity in the use of soil, and by the comparative difficulty of securing wood supplies cheaply enough from outside. On the other hand, such countries as the Mediterranean peninsulas by their advantageous situation with reference to importations, with their mild climate and less intensive industrial development, have felt this need less.
Again, the still poorly settled and originally heavily timbered countries of the Scandinavian peninsula and the vast empire of Russia are still heavy exploiters of forest products and are only just beginning to feel the drain on their forest resources; while the United States, with as much forest wealth as Russia, but with a much more intensive industrial development, has managed to reach the stage of need for a conservative forest policy in a shorter time.
From each of the European countries we learn something helpful towards inaugurating such policies, and while, owing to a different historical background and to different political and social conditions, none of their administrative methods and measures may appeal to us, the principles underlying them as well as those underlying their silvicultural methods remain the same; they are applicable everywhere, and can best be recognized and studied in the history of their development.
THE FOREST OF THE ANCIENTS.
Waldgeschichte des Alterthums, by August Seidensticker, 1886, 2 vols., pp. 863, is a most painstaking compilation from original sources of notes regarding the forest conditions and the knowledge of trees, forests and forestry among the ancients. Contains also a full bibliography.
Die Waldwirthschaft der Rœmer, by J. Trurig, collects the knowledge, especially of arboriculture and silviculture, possessed by the Romans.
