THE METEOROLOGICAL SERVICE OF CANADA 
The ordinary climatic and forecast work of the meteorological service 
has been carried on systematically throughout the year and in addition 
investigation of the connection existing between the meteorological 
phenomena in Canada and in other parts of the globe has been ener- 
getically pursued with the object of discovering causes which lead to 
changes in the general atmospheric circulation. 
International co-operation in meteorological research is now regarded 
as essential to the solution of some of the many vexed problems which 
confront the meteorologist. A committee elected at the Meteorological 
Congress in Innsbruck in 1905 arranged that the various countries 
represented by its members should send meteorological reports to the 
Solar Physics Obeservatory, South Kensington, there to be printed and 
correlated together with measurements of the solar radiation; the 
pyrheliometer by Prof. Angstrom being the instrument chosen as a 
standard for the latter determinations. The meteorological service has 
been supplying the data asked for from Canada, namely abstracts of 
observations made at Dawson, Port Simpson, Victoria, Calgary, 
Qu Appelle, Winnipeg, Port Arthur, Parry Sound, Toronto, Kingston, 
Montreal, Father Point, Fredericton, Halifax, St. Johns, Nfid., and 
Bermuda. 
Another international work to which Canada lends its assistance 
is the compilation of a daily chart of the Northern Hemisphere between 
Scandinavia and Northern Canada; the chart in question being printed 
by the Deutsche Seewarte in Hamburg. 
An important problem awaiting solution is, whence come the high 
areas which appearing in Northwestern America move southeast and east 
accompanied by cold waves? 
It appears quite probable that the recent opening of new Canadian 
observing stations in the far north may shew that the general distri- 
bution of atmospheric pressure over America is not as was supposed and 
that the average path of the centres of both high and low areas lies much 
more to the northward than has heretofore been indicated. During the 
past winter the pressure over Yukon and Mackenzie River Territory 
has been very abnormal, as it has also been over the North Atlantic and 
Western Europe and it would appear almost probable that the wide 
departures from average which have been recorded may afford most 
valuable data for the determination of causes leading to the abnor- 
malities. 
Continued study of the climatic conditions of Northern Canada 
further tends to confirm the belief that, in the basin of the Mackenzie 
River the summer conditions are suitable for some agriculture nearly 
to the Arctic Circle. 
For the three summer months a vast area which includes western 
and Northern Alberta, northern Saskatchewan and the basin of the
