Silvicultural Practice. 183 



results of Ms investigations (under the order of the Bund 

 of 1857) of the forest conditions of the Alps and con- 

 tributed other volumes along similar lines. 



He -was succeeded by the now venerable Dr. J. Coaz as 

 Inspector-General of the Bund, who also contributed to 

 the science of mountain reboisement and in other direc- 

 tions. The work on the management of the City forest 

 of Zurich by its long-time manager Meister is classic. 

 Under the active direction of Anton Buhler for many 

 years (now Dr. Engler), Mittheilungen der eidgenos- 

 sischen Centralanstalt fur das forstliche Versuchswesen, 

 have become since 1891 important contributions to for- 

 estry science. In the direction of wood technology the 

 name of L. Tetmajer, who is conducting timber tests 

 should be mentioned. 



The timber forest is the most general form of silvi- 

 cultural management. Selection forest with 150 to 200 

 year rotations is practised in the Alps and in the smaller 

 private forest areas. Shelterwood system in compart- 

 ments is in use in other parts (with a rotation of 60 to 

 80 years in the deciduous and 80 to 120 years in conifer 

 forest), supplanting largely the clearing and planting 

 system which had found favor during the middle of last 

 century. 



In corporation forests large areas are still under cop- 

 pice with standards, but will probably soon be converted 

 into timber forest, a policy favored by cantonal instruc- 

 tions. Pure coppice is only rarely met, usually con- 

 fined to the overflow lands and small private holdings. 

 In some of the public forests in the French territory it 

 is practised with a "double rotation" (furetage) accord- 

 ing to French pattern.
