prints were made to the scale of 3.95 miles to the inch. Only the main topographical 

 features required were inked over and traced directly on to the manuscript. 



Map Mounting and Preservation 



114 original township survey plans were treated with a cellulose wash finish 

 to preserve and protect the surface. During the year, 106 maps or plans were mounted 

 in various ways. These included original survey plans for this Section and new survey 

 plans for the Patents, Land Titles and Registry Offices. 



Survey Records 



4,800 rolled survey plans were cleaned and given a new filing number, and 

 transferred from the old pigeon hole filing system to new steel drawer filing cabinets. 

 This included some 750 original Railway Right of Way plans, transferred from the 

 Department of Public Works. 



The handling of original survey records plans and field notes continued to be 

 a major item through the year due to the extensive activity in highway, hydro, summer 

 resort and other phases of survey work. 



Field Survey Party Equipment and Supply 



The equipping and supplying of 4 field survey parties for Crown summer 

 resort work in the Muskoka and Parry Sound Districts, and for survey inspection 

 work, was taken care of during the year. Major field survey party equipment purchased 

 during the year included a new International panel truck which was outfitted as a 

 mobile survey unit. A boat trailer for use with the truck was constructed, and a 

 16-foot outboard boat was built by the staff of one of the Districts for our use. A 

 quantity of 1" and y^" iron survey bars, and preliminary survey summer resort 

 location tags were purchased and distributed amongst the various District Offices, where 

 they will be required for the coming summer's survey program. 



The new larger storage space, consisting of approximately 1,000 square feet in 

 a building built for the use of this Division, and the Division of Research, was 

 completed by the Department of Public Works on this Department's Southern 

 Experimental Station property at Maple, for the storage of survey equipment and 

 supplies. The part occupied is the centre section of a prefabricated "Quonset'' hut 

 which was divided into 2 floors, and the walls insulated. The second floor is con- 

 structed on pillars, and is entirely free from the walls, as no weight can be attached 

 to the laminated ribs of the hut itself. The building is heated by steam, with a blower 

 system from an oil burning furnace. This also provides additional storage space for 

 duplicate and other survey records not in constant use. 



Provincial Air Photographic Library 



Approximately 1.000 photograi)hs covering points in Southern Ontario, from 

 photograph}- made by our Aerial Surveys Section, with a few key maps, were prepared 

 by the Aerial Surveys Section for the Provincial Air Photographic Library this year. 

 In this connection also, the Forest Resources Inventory Section of the Division of 

 Timber Management o!)taine(l and stored a number of prints of their planimctric base 

 maps ready for the keying of the photograjihs.
