THE METEOROLOGICAL SERVICE OF CANADA 



In the report of last year attention was called to the ever in- 

 creasing demand by pulp and water power companies for information 

 regarding rainfall, and it can now be stated that good progress con- 

 tinues in placing rainfall stations in the more northern districts where

 of weather forecasts and storm warnings have been carried on with- 

 out break with the result that 91-0 per cent of the storm warnings 

 have been verified.
