a teacher he excelled in clearness, 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 practice, professor of forestry at Tuebin- 

 gen, in 1817, and at Giessen, 1825. He was a representa- 

 tive 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 form- 

 ula 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 measur- 

 ing forestal forces," being thus the forerunner of modem 

 scientific forestry. 



The fourth of the group, Oottloh Konig (H]|6-1849) 

 was a practitioner 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 con- 

 tributions to the scientific, especially the mathematical 

 side of forestry, developing forest mensuration and 

 statics. In this latter branch he was the forerunner 

 of Pressler and the modem school of finance. In his 

 "Anleitung zur Holztaxation" (1813) he gives a com- 

 plete account of forest mensuration and in the part 

 devoted to forest valuation he develops the first soil 

 rent formula and the methods of determining the cost
