ultimate status of the lamprey Is determined and the effect of lamprey control 

 undertaken by the Federal Government is properly assessed. 



Several mile-posts have been passed in wildlife research. The vege- 

 tation map of the Wilderness Research area, which was started in 19^9> was 

 completed in 195^9 ^^^ will be related to other projects* The series of phono- 

 logical plots in the area, which were established in 19^9 have now been 

 established in 11 representative plant communities* Sufficient data have been 

 accumulated from beaver in the deciduous forest to show sex and age ratios of 

 colonies and the physical character of dams and ponds in the study curea* 



A still for the distillation of essential oils from conifer leaves^ 

 mostly leaves of black spruce, was built in 195^ and successfully operated by 

 the Mechanical Research Section of the Division. This still was of the single 

 charge type and it was considered by observers that a continuous process still 

 would have some advantage* This was designed and made and is now in process of 

 being tested* Millions of pounds of conifer foliage are produced each year in 

 the process of logging, and a valuable oil may be obtained from it* The yield 

 to be expected runs from -J* to 1 percent of the weight of foliage and the sales 

 value Is around $2 per pound at present* If this still is successful, a valuable 

 product will be added to the long list already obtained from the forest* 



In the following pages a more detailed report of the foregoing and 

 other projects Is given*
