3. Canada: Toronto. Meteorological Observatory. 
Professor R. F. Srupart, Director. 
The instrument has been moved from the small building outside the 
Magnetic Observatory to the inside of the same. One result is that air 
tremors have apparently entirely disappeared. The Observatory is 
situated on a bed of alluvium, perhaps 100 feet in thickness and stretching 
20 miles North, East, and West with Lake Ontario on the South. Beneath 
the alluvium are granitic and other primitive rocks. 
The purchase money for the Toronto instrument and the funds required 
for the installation and maintenance of the same, and also for the installa- 
tion of a seismograph at Victoria, B.C., have been provided by the Dominion 
Government. The excellent series of results obtained from these stations, 
amongst other things, throw light upon changes taking place aiong the 
Eastern and Western Canadian seaboards. They have already attracted 
the attention of scientific men, and will undoubtedly act as an incentive 
for other Governments to work on similar lines.
