of economic value, that I initiated Silvicultural experi- 

 ments at Sapoba. I selected an area in the most important 

 forest, where I demarcated a Working Area of about 

 six hundred acres. It was in the heart of the Rain Forest 

 within the Jamieson River Forest Reserve. I divided the 

 Working Area into four blocks, each containing five 

 compartments of thirty acres each. The systems under 

 experiment within this Area were: 



The Transition Method 

 Uniform System 

 Periodic Block System 

 Walsh's System. 



In the case of the Transition Method the treatment 

 preceded felling operations, with a view to securing 

 natural regeneration of as large a percentage as possible 

 of better class species. Under this system the following 

 species have been treated: Khaya sp., Entandrophragams 

 sp., Lovoa Klaineana, Guares sp., and Iripiochiton sp. 



Under the Uniform System thirty acres are being dealt 

 with annually, and excellent results have already been 

 obtained. There are healthy groups of young regenera- 

 tion of Khaya sp., Lovoa Klaineana, Guarea sp., and 

 Gossweilerodendron balsamiferum. 



The importance of these Silvicultural experiments 

 cannot be overestimated, and their significance will be 

 obvious not only to my many Forester friends in the 

 United States, but to importers of mahogany and the 

 Captains of Industry, whose enterprise is so dependent
