Thinnings In Aspen 



The young stand was thinned In 1953* It was remeasured In 195^* 



Poster Comparison Study 



At the request of the Division of Forest Protection a study was made on 

 poster durability under severe weather conditions. A new plastic covered poster 

 iras tested* 



Essential Oils 



A pilot plant for the distillation of essential oils from spruce foliage 

 iras set up at Heron Bay* This project was Integrated with a new logging technlqpi* 

 being developed by the Ontario Paper Company* This technique, whereby tree lengths 

 irere carried to a central landing, resulted In the accumulation of large amounts 

 9f slash. To overcome this, the slash was put through a chipper to reduce Its 

 irolume and make It easier to handle* 



It was this chipped material that provided the leaf still with Its raw 

 naterletl* The still was In operation during the Annual Field Meeting of the 

 forestry Advisory Committee to the Research Council of Ontario* A great deal of 

 Interest was aroused among the delegates, In the distillation process* 



The still functioned satisfactorily for purposes of demonstration but 

 iras too slow for production use* About five gallons of high grade essential oil 

 vas produced during the demonstration* 



Further refinements to the boiler and still are planned In order to 

 Increase production* The site of future tests will be the Research Block In the 

 Cochrane District* 



Seed Collection for Greenland 



At the request of the Danish Government through the Forestry Branch, 

 several pounds of white spruce seed were collected near the mouth of the French 

 Uver on the James Bay coastcuL plidn* 



Other Work 



During the summer some time was spent In the field with resesuroh parties 

 rrom other organizations* 



W* K* W. Baldwin from the NatloncuL Museum, Ottawa, completed his work 

 m the Clay Belt flora. Two days were spent In the field with him* 



D* W* MacLean, Forestry Branch, Ottawa, was visited during his studies 

 >f stand histories In mixed stands* 



Preliminary work was done In connection with a project planned for next 



ear in the Bnglehart Management Unit*
