representatives of France, Germany, Italy, and Great Britain to find
some solution of the problem which might be satisfactory to both Austria
and Russia. Italy and France agreed at once, but Germany raised
objections. Germany's only suggestion for preserving the general peace
of Europe was that Austria should be permitted to deal with Serbia as
she pleased, without interference from any other power. And so it
continued through those critical days. Every effort made by England
looking toward a peaceful settlement of the quarrel was baffled by
Germany's refusal to coöperate. This is not difficult to understand in
