He compiled in four volumes a dictionary of forest, fish and game practice (_Onomatologia forestalis-piscatoria-venatoria_, 1772-1781) and founded the first forestry journal.
Since 1770, forestry courses had been given for the cameralists at most of the German universities, and many of the professors prepared textbooks for the purpose. At least three of these professors deserve mention, Beckman, Jung and Trunk.
The first, _J. Beckman_, professor of political economy at Göttingen, one of the most noted cameralists, was author of a work in forty-five volumes on the _Principles of German Agriculture_ (1769), in which he devotes sixty-one pages to forestry, giving a complete system of forestry, with extracts from all known forestry writings.
_J. H. Jung_, who gave a special course on forestry at the Kameralschule of Lautern, published a textbook in 1781 in which forest botany was well treated.
_J. J. Trunk_, who was Oberforstmeister in Austria, as well as professor at Freiburg, was the most prominent of the three, and wrote a comprehensive work full of practical sense (_Neues vollständiges Forstlehrbuch oder systematische Grundsätze des Forstrechtes, der Forstpolizei und Forstökonomie, nebst Anhang von ausländischen Holzarten, von Torf und Steinkohlen_, 1789).
While at first the ephemeral writings, especially the polemic ones of the empiricists, found room in literary and cameralistic magazines, the need of a professional journal first found expression in 1763, in Stahl’s _Allgemeines ökonomisches Forstmagazin_, which ran into twelve volumes, and contains many articles important to the history of forestry, and is especially rich in its references to foreign literature.
Two continuations of the magazine under different editorships were of less value. But von Moser’s _Forstarchiv_, running from 1788 to 1807 with its thirty volumes, is an authority and a historical source of the first rank.
A very characteristic literature of the last half of the 18th century consisted in _forest calendars_ in which advice as to monthly and seasonal procedures in the forest were given, Beckman and Zanthier being among the authors.
III. DEVELOPMENT IN THE NINETEENTH CENTURY.
The last hundred years or so has seen in Germany the development of fully established forest policies and the complete organization of stable forest administrations, based upon thorough and careful recognition of the principles of forest management and intensive application of silvicultural methods.
