An International Convention, attended by representatives of all trades in

Canada and the United States, has been held at Detroit, in Michigan. The object was to consider the propriety of renew- ing the Reciprocity Treaty, and the final decision was in its favour, as equally beneficial to Canada and the United States. This is satisfactory, but the United States Consul-General in Canada is not of that opinion. He believes that if the United States will only forego the benefit of the treaty for two years, the Canadians will annex themselves to the Union. If they do, a supposition simply ludicrous, they will be the first people ever conquered by that often tried form of aggression—a war of tariffs.
