INTERNATIONAL SCIENCE CONFERENCE 219 
Dominion Government which has a Dominion Observatory 
in Ottawa, and an Astrophysical Observatory at Victoria. 
The subject is also ably supported by the Royal Astrono- 
mical Society which has its Headquarters at Toronto. It 
is thus quite fitting that an International Committee repre- 
senting Astronomy should be formed in Canada. 
Under the International Organization, the Union of 
Geodesy and Geophysics is still môre comprehensive. The 
work carried on under this heading by the Dominion Go- 
vernment, is under the direction of four different depart- 
ments. In the Department of the Interior, there is the 
Topographical Survey, under the Surveyor General ; the 
Geodetic Survey of Canada, including triangulation and 
levelling ; and also the investigation of earthquakes and 
terrestrial magnetism, under the direction of the Dominion 
Observatory. In two other ‘departments, there are the 
Geological Survey, and the Meteorological Service for the 
study of climate. In the Naval Service department, there 
is the Hydrographic Survey engaged in making charts of 
the coastal regions and the Great Lakes ; and the Tidal 
and Current Survey, which includes the investigation of 
the tides on the Eastern coasts of Canada and on the 
Pacific, as well as in Hudson bay. The National Commit- 
tee of Geodesy and Geographysics for Canada includes 
the men at the heads of these various branches in the 
Government Service ; as well as a professor in one of our 
western universities, making ten in all. 
When it was decided to hold an International Conference 
at Rome in May of this year, the National Committee 
appointed five delegates, three of whom are being sent to 
the Conférence by their respective departments in the 
Government service. These are Dr. Otto Klotz, Director 
of the Dominion Observatory, representing astronomy ;
