Silviculture: 



The general object of these studies is to obtain information for sustained 

 forest management. The work of the Research Division in the period reported 

 on was undertaken to determine the adequacy of stocking of desirable species 

 following cutting and fire and to devise methods to correct deficiencies. Experi- 

 ments are or will be set up to check the results from recommended procedures 

 in actual practice. 



Surveys under this heading were carried on in the following areas in 1946: 



(1) Northern Cla>- Belt in the Kapuskasing District. This survey was under the 

 direction of Professor R. C. Hosie and was originalh' organized in 1945 as a 

 cooperative effort with the University and the Spruce Falls Power & Paper 

 Co. The 1946 survey was intended to complete the work of 1945. A report 

 has been published on both seasons' work. 



(2) In the Goulais River area north of Sault Ste. Marie. This work was under- 

 taken in 1945 to stud\- the effects of logging on a mixed stand and was 

 undertaken as a cooperative effort with the Dominion Government. The 

 main effort during the past summer was to relocate sample plots set out 

 during the late 20's. No report has as yet been issued by the Dominion 

 Forest Service who control this project. 



(3) In the Port Arthur and Kenora Districts. These surveys were undertaken 

 to study regeneration following logging and fire. The species studied were 

 mainly spruce, jack pine and poplar. The work was organized by the 

 Research Division and was under the general direction of Mr. Peter Addison 

 and Mr. Wilson Cram, Regional Foresters at Port Arthur and Kenora respec- 

 tively. The field work was conducted b\- A. P. Leslie and H. C. Larsson, 

 assisted by 18 students. Some 150,000 acres were examined during the 

 season . 



Soils: 



The main object of this work is the separation of agricultural and forest 

 soils and the classification of forest soils to ensure their most productive use. 

 It was carried on under the direction of G. A. Hills, l-'icld work was mainly 

 in the Cochrane District and covered approximateh" 50,000 acres. A soil anahsis 

 laboratory was established at the Southern Research Station near Ahipie, 

 Ontario. The results of these soil surveys can be used as a guide to land settle- 

 ments and will also define the area of the Province which should be used for 

 the growing of forest products. 



.Smelter Fumes: 



This study is a continuation of the work of 1944-45 to determine damage 

 to the forest b\- fumes from smelters at Sudbur\- and l-'alconbridge. Meld work 

 consisted of aerial sampling in the smelter smoke and on the ground using an
