THE METEOROLOGICAL SERVICE OF CANADA. 



The work of the Meteorological Service has progressed satisfactorily 

 during the year. The International Weather Map is, as it is becoming- 

 better understood, proving of much assistance in maintaining the 

 efficiency of the Forecasts and Storm-Warnings. 



The increasing number of enquiries from all portions of the Do- 

 minion for the regular and special forecasts, as well as for statistics 

 of climate, shew that the people of this country appreciate the facilities 

 for information which it is the aim of the Service to maintain. Many 

 enquiries have come from other countries also, especially from intending 

 immigrants, and from various firms intending to open branch offices 

 or factories in the Dominion. 



Research into the conditions in the Upper Air has 1)een carried on, 

 as last 3^ear, by means of kites and balloons. 



Arrangements have been made with the Printing Bureau so that 

 the publications of the Service will in future be issued with greater 

 dispatch. 



Physics Branch. 



The exploration of the upper atmosphere by means of kites and 

 balloons was continued during the year. Balloons carrying meteoro- 

 graphs were sent up on the 29 evenings preceding the International 

 days between the 1st January, 1912, and the 31st March, 1913, from 

 Woodstock, Ont.; 16 of these were sent up between the 1st of January 

 and the 6th July, 1912, and 10 of them have been recovered, but out of 

 the 13 sent up during the remainder of the period, only 4 have been re- 

 turned, and all of them travelled a long distance, one being found at 

 La Tuque, near L. St. John, Quebec. The table on next page gives 

 a summary of the results. 



The kite station at Agincourt has been in operation throughout 

 the year and some good records have been obtained. The highest 

 point reached was about 6,750 feet above sea level. 



Observations were commenced during the year on the potential 

 of the air. A small house was erected near the centre of the Observ- 

 atory grounds for the necessary apparatus. The potential is measured 

 by a self-recording electrometer designed by Mr. Patterson ; this instru- 

 ment gives a continuous record of the potential of the air when used 

 with a collector; the collector consists of a small deposit of polonium 

 on copper, protected from the weather, and exposed at the end of an. 

 insulated rod, 8'. 6" above the ground and 9' from the building.
