LXVI THE ROYAL SOCIETY OF CANADA 



Northern Railway, and arrangements have recently been made to 

 issue a daily forecast to places in the Interior of British Columbia. 

 The percentage of verification of the daily forecasts was 87 '5. 



The Monthly Record of Meteorological Observations which as 

 stated in my last Report has taken the place of the Annual Climato- 

 logical Report, has been brought almost as closely to date as is pos- 

 sible, and the Service can no longer be reproached for issuing belated 

 reports. The Monthly Map published from four to five days after 

 the close of each month gives most valuable information regarding 

 the progress of the seasons and is greatly appreciated by all directly 

 concerned with agricultural operations. The daily weather map has 

 been issued without a break throughout the year and much of the data 

 it contains is telegraphed to all parts of the Dominion. The Report 

 of the Toronto Observatory which has been issued annually since 

 1860 is now printed in the Meteorological Office press and was in 

 print at an earlier date this year than ever before. It contains data 

 which is of much interest now and will be of the utmost value in the 

 future. Never in the history of the Service have there been so many 

 applications for Meteorological data as during the past year, and in 

 many instances the preparation of the particular data asked for has 

 entailed considerable clerical work. Applications have been received 

 from Government offices, electrical development engineers, railways, 

 legal firms, cities, pulp wood companies, irrigation engineers, agri- 

 cultural institutes, farmers, prospective immigrants and many others, 

 and all enquiries have been replied to as fully and promptly as 

 possible. 



The Percentage of verification of "storm warnings issued for 

 Canada was 84-1.

Balloons with self-recording instruments for upper air investiga-
