General Administration, Map Distribution and Survey Records 



Map Distribution 



A considerable increase is to be noted in the overall distribution figures of 

 all maps. This was due mainly to the opening of Highway 17 connecting Sault 

 Ste. Marie with Port Arthur, for which map number T2800, showing general 

 information along the highway, and plan number T2210, covering Lake Superior 

 Provincial Park, were prepared, for the anticipated influx of tourists. 



A total of 32,865 copies of lithographed district and miscellaneous maps 

 produced by this department were distributed, of which 1,750 copies were for 

 the "official use" of this and other departments of the provincial and federal 

 governments (see "Trend of Map Distribution Charts"). 



The map sheets of the National Topographic Series, produced and distributed 

 by the Federal Department of Mines and Technical Surveys, as well as the 

 sheets produced by the Army Survey Establishment Bureau of the Department 

 of National Defence, Ottawa, for resale purposes, or for the "official use" of 

 this and other departments of the Ontario Provincial Government, were distributed 

 in the total quantity of 45,848 copies (see "Trend of Map Distribution Chart"), 

 an increase of 8,855 copies over that of the previous fiscal year. Of the total 

 distributed, 14,267 copies were supplied for the "official use" of this department, 

 including district offices, by the E>epartment of Mines and Technical Surveys,
