Report of the Department of Lands and Forests for 1950 



If the early part of 1949 is favorable in respect to precipitation and temperature, sur- 

 vival may be much higher. Survivals of 2S',[ have been obtained in other areas 

 under very favorable conditions. 



Smelter Fumes 



The smelter fumes survey, under R. H. Murray, that was started in 1944 was 

 stopped in 1948 to assess the results of the work and establish a proper basis for 

 possible continuance on an enlarged scale. 



Soils 



The soils survey, under G. A. Hills, during 1948 was continued in the Hali- 

 burton region, which is the fifth area covered since the start of soil surveys in 1944. 

 As in past years, the principal effort has been to map soils in terms of possible use 

 and yield for forestry and farming purposes and thus to define, in general, those 

 areas best suited for forest or farm development. 



During the field season, 36.000 acres of land were covered, extending from 

 Coboconk to Huntsville and including the University of Toronto Forest. 



Work was continued on chemical and physical analyses, and base exchange 

 of soils at the Maple Laboratory. Work was almost completed on reports and maps 

 of Grant and McLaren townships in the North Bay district. 



Statistics 



A start was made on detailed statistical studies when Dr. DeLury was engaged 

 as a consultant of the Ontario Research Foundation. ]Mr. Lachlan M. Morrison has 

 been added to the Division staff to assist Dr. DeLury and perform other work. 



An improved system of forest sampling has already been developed by Dr. 

 DeLury and will be tried out thoroughly in the field.
