were determined and the results forwarded to him. Assistance was 

 also given to members of his staff in determining the constants of 

 their Total Force Instruments both before and after their field work. 



Members of the staff of the Dominion Observatory were also 

 assisted in standardizing their magnetometers and Dip Circles. 



Many special reports were made for enquirers and surveyors 

 who required data for specified places and times. 



A Report was also made of the work of the Canadian Magnetic 

 Observatories and of the Intercomparison of Magnetic instruments in 

 Canada for presentation at the Rome Meeting of the International 

 Geodetic and Geophysical Union. 



The Observatory at Meanook was continued in operation as 

 before. During the very cold weather some loss of record occurred 

 owing to stopping of the driving clock. 



Weekly observations were made of absolute Declination and 

 Inclination and twice a month observations of Horizontal Force. 



The Declination photographic traces for both Agincourt and 

 Meanook were loaned to the Surveyor General and the Agincourt 

 Declination traces to the Dominion Observatory for use in the reduc- 

 tion of their field work. 



The accompanying tables give a summary of the results obtained 

 at Agincourt and Meanook during the fiscal year 1921-22.
