Report of the Department of Lands and Forests for 1950 No. 3 



DIVISION OF SURVEYS AND ENGINEERING 



Early in April, 1948, the survey of the portion of the Ontario-INIanitoba 

 Boundary between Island Lake and the intersection of the 89th meridian of west 

 longitude of Hudson Bay was completed. Astronomical observations to determine 

 the position of this point had previously been made and a concrete monument planted 

 to reference this point. The line struck 15.8 feet off the point so determined. This 

 remarkable closing shows the accuracy with which the work was carried out. Credit 

 is due to those in charge of the field work. 



The nature of the terrain over which the line passed was such that the work 

 could only be carried on during the winter months. The Manitoba Government Air 

 Service, operating from a base at God's Lake, was used to transport the party and 

 supplies. When suitable lakes were adjacent to the line, the aircraft was used to move 

 camp and ferry the members of the party to work from camp. Without this service, 

 it would not have been possible to accomplish the amount of work completed. 



When the line has been accepted by the Governments concerned, permanent 

 monuments will be established at convenient intervals. Legislation confirming the 

 Boundary as established, will then be passed by the Parliaments. 



The baseline from the south east corner of the Nipigon Forest Reserve was 

 completed to the boundary between the Districts of Thunder Bay and Algoma. 



The Department has adopted the policy of preparing plans for registration, 

 when five or more adjacent summer resort locations or five or more locations within 

 the same township lot are surveyed simultaneously. This simplifies the issuing of the 

 patents of these locations and subsequent transfers if so desired. 



Power developments at Terrace Bay on the Aquasabon River in the District of 

 Thunder Bay, at Stewartville on the Madawaska River, in the County of Renfrew 

 and on the Muskoka River, in the District of Muskoka, were completed during the 

 year and are now providing electric energy. 



The concentrated survey programme of uncompleted surveys of summer resort 

 parcels was continued and 1,199 surveys were completed, an increase of 73.3 per cent 

 ov^er the previous fiscal year.
