(March 13th, 1890.) 
This discussion was initiated by Mr. Frank Phillips, who furnished 
a variety of statistics relating to the Australian colonies. He was 
favourable to a scheme of Federation as greatly to the benefit of 
our colonial empire, but considered that very grave difficulties 
had to be overcome in dealing with divergent interests. He 
hoped, however, to see a grand Federation of the Australian 
colonies.

anchovies and Norwegian anchovies ; (2) The destruction of
