DIVISION OF SURVEYS AND ENGINEERING 



The programme of extending base and meridian lines in the north- 

 western portion of the Province to provide control for mapping from aerial 

 photography and to assist in determining potential forest resoiirces was 

 continued. The meridian in approximate longitude 92 degrees and 56 minutes 

 was extended hQ miles and a portion of the Fifteenth Base Line produced 

 toward the Ontario-Manitoba Boundary. The mining activity in the Manitou- 

 wadge area in the District of Thunder Bay and the establishment of a town- 

 site made it necessary to survey township outlines. There was a decrease 

 in the niimber of applications for summer resorts and this enabled the in- 

 auguration of a programme of surveying the majority of these locations as 

 subdivisions and preparing plans for registration. Some progress was made 

 in the re-surveys of obliterated township subdivisions. 



The distribution of lithographed map sheets was less during the 

 past fiscal year. This reduction was caused by not obtaining the revised 

 map of parts of the Districts of Algoma and Sudbury until late in the year 

 and having to curtail the distribution of map of the Province on the scale 

 of thirty-five miles to an inch which is being revised. It has also been 

 noted that the white prints of individual large scale maps have been re- 

 quested instead of the lithographed maps on smaller scsiles. 



The revision of base maps was continued. A new map of Quetico 

 Park is being prepared which will include the additional topographical in- 

 formation obtained from aerial photography. It is anticipated this map 

 will be available before the tourist season. Type- face lettering is being 

 used in all our maps instead of hand-drawn lettering. Shore lines of lakes 

 and streams and the names of these features are shown blue on new maps 

 being issued. This change has added much to the appearance of the map and 

 made the features more easily identified. Base drawings are being prepared 

 for a revised map of Southern Ontario.
