DIVISION OF SURVEYS AND ENGINEERING 



Magnitude of new investments and developments of the natuTEil 

 resources of the Province has increased the work in all of the branches of 

 this Division. 



The largest programme in recent years of the extension of the 

 network of meridian and base lines for the control and mapping from aerial 

 photography was undertaken during the yearo The Thirteenth Base Line at 

 approximate latitude 52 degrees and 30 minutes was surveyed > extending from 

 the Ontario-Manitoba Boundary eastj a distance of one hundred and seventy- 

 four miles • At approximate longitude 92 degrees a meridian was surveyed 

 north from the Thirteenth Base Line a distance of forty-eight miles to estab- 

 lish the Fifteenth Base Lineo This base line was produced west a distam.ce 

 of thirty- two miles* The sale of Crown lands for summer resort locations 

 made it necessary to increase the number of resurveys of old township surveys 

 to establish obliterated lot corners* 



There was a marked increase in the demand for maps published by 

 this Department and those of the National Topographical Series* The District 

 Offices have prepared tracings on a scale of two miles to an inch of areas 

 not covered by the National Topographical Series. Booklet (Form S. 82) was 

 issued illustrating the definition of frontage, side, width, regular area, 

 irregular area, minimiun and maximum areas of land to be disposed of for 

 private or commercial summer resort locations on Crown lands. A Manual of 

 General Survey Instructions (Form S. 8h) was prepared and issued governing 

 the survey of summer resort locations and water lots as required by this 

 Department. 



A new map was prepared and published showing the Electoral Districts 

 in accordance with the provisions of the Act respecting Representation of the 

 People in the Legislative Assembly. Revised base maps are being prepared for 

 the Districts of Algoma and Sudbury, using type-face lettering and figures 

 instead of the hand-drawn lettering formerly used. The map of islands in
