The oil yield was not as high as expected. There may have been tiro 

 reasons for this: (1) Extraction from s\ammer leaves may be lover than from spring J 

 leaves, and (2) the boiler capacity was insufficient. A more suitable boiler has 

 since been procured. 



As a result of these tests, a new type of still is being designed, having 

 a capacity of about 800 lbs. of raw material per hour. This still will operate on 

 the continuous process principle, which, it is hoped, will still further cut down 

 on the oil extraction time. For ease of transport, this apparatus will be trailer- 

 mounted, so that it can be easily set up at any suitable pulp cutting operation. 



If an economical apparatus can be produced for extracting the essential 

 oils from conifer leaves, it will be possible to utilize large quantities of raw 

 forest material which are now going to waste. 



Post Peeler 



A post peeler, to be used in the County forests of the Lake Simcoe 

 District, was produced in the winter of 195^* A machine of this capacity is 

 calculated to peel a maximum of 38 posts per hour. It can be driven by any tractox 

 equipped with a power take-off. 



Tree Baler 



An electrically operated tree baler was produced for studying new 

 methods of shipping nursery tree stock. This machine will turn out bales up to 

 18 inches in diameter. It has also been found that baled trees are well suited 

 for dropping from aircraft to remote planting areas. This machine will be tested 

 at the provincial nurseries during the spring shipping seasono 



Pack Tractors 



Several minor modifications were made in the commercially produced pack 

 tractors. 



Engineering Services 



Layout plans and specifications were prepared for the dlesel-powered 

 ^-foot steel boat built for fisheries research. The used dlesel marine engine 

 was reconditioned at this station. In addition, suitable personnel were supplied
