cussion, are matters for international con- 
gratulation. It will be remembered that 
Great Britain declined to take part in a 
joint conference in which Russia and Japan 
were to be represented. This led to the 
holding of two distinct conferences—the 
first with Russia and Japan; the second 
with Great Britain and Canada. In the 
first there were few if any points of dispute, 
and an agreement was promptly reached

States, Russia and Japan pledged them- 
selves to desist from pelagic sealing for a 
period of one year, pending subsequent 
negotiations.
