The Kite station at Agincourt for observations in free air has been 
in operation throughout the year. The equipment is similar to that 
employed by Dines at Pyrton Hill and the Dines’ kites and meteoro- 
graphs are used. These kites are very easily constructed and the 
meteorographs are not expensive; for these reasons it was considered 
advisable to use them at first until the station was in good working order, 
after which other kinds and types will be tried. Records of pressure, 
temperature, humidity and wind direction have been obtained. As- 
cents began on the 28th February 1911 and the highest flight was 7900 
feet above sea level obtained on the 28th June, 1911. 
The movement towards the utilization of water-falls for the pro- 
duction of electrical power has made a knowledge of the rainfall in the 
various water-sheds, a matter of great importance and during the past 
year numerous rainfall stations have been established in districts 
where hitherto reports have been either scant or altogether wanting. 
At the close of the year there were in the Dominion 543 stations 
of all classes reporting to the Central Office in Toronto, an increase of 77 
from the previous year. Forecasts have been issued from Toronto 
twice daily for the succeeding 36 hours for all the provinces, exclusive 
of British Columbia and for these a per cent of 86-1 was attained. For
