Compilation of a map "Location of dams on Principal Watersheds in Southern 

 Ontario" commenced with a preliminary editing by the departmental District 

 Foresters of the existing "Locations of Dams" maps. The map is to be prepared 

 in such a manner as to permit the base to be used for similar subject overlays. 



EDITING OF GEOGRAPHICAL NOMENCLATURE ON MAPS 



All nomenclature on the following maps produced by federal mapping agencies 



were investigated and edited at the request of the Canadian Permanent Committee 



on Geographical Names, Ottawa: — 



1:25,000 82 



1:50,000 10 



1 : 125,000 15 



1:500,000 or 8m/l" 2 



Canadian Hydrographic Service Charts 8 



In addition, assistance and recommendations were made to the Committee 



on more than 1,000 contentious names not including those for, the maps listed 



above. Most of these resulted from the intense field investigations of geographical 



names in Renfrew County by the Committee. 



Twenty-three maps to be produced by Provincial Mapping units were 



examined and nomenclature edited. 



Continuing revision to the Geographical Index resulted in the revision to and 



addition of 2,300 cards.
