 exposition, wealth of ideas and geniality. 



Of an entirely different stamp was the third of the 

 great masters, Johann Christian Hundeshagen (1783- 

 1834), who having studied in Heidelberg, became 

 after some years of pracitce, professor of forestry at 

 Tuebingen, in 1817, and at Giessen, 1825. He was a 

 representative of the theoretical or philosophical side 

 of forestry, being highly cultivated and imbued with 

 the spirit of science. His bent was to systematize 

 the knowledge in existence and extend it by means 

 of exact experiments. In forest organization, he 

 invented the well known formula method or "rational 

 method" of regulating felling budgets and became also 

 one of the founders of Forest Statics (1826) which he 

 called "the doctrine of measuring forestal forces," 

 being thus the forerunner of modern scientific forestry.

 was a pracitioner without a university education, 

 who had enjoyed the teaching and influence of Cotta 

 whom he succeeded in Eisenach as the head of the 

 ducal forest administration. He also founded here 

 a private forest school, which, in 1830, became a 

 state institution, and is still in existence. Konig 

 became noted by his contributions to the scientific, 

 especially the mathematical side of forestry, develop-

 branch he was the forerunner of Pressler and of the 

 modern school of finance. In his "Anleitung zur 

 Holztaxation" (1813) he gives a complete account of 

 forest mensuration and in the part devoted to forest 

 valuation he develops the first soil rent formula and
