period in Washington, as an act of aggression "the most unjust which can be found in the annals of modern history" and designed to despoil a friendly nation of a considerable portion of her territory. He announced, in consequence, the termination of his mission, and demanded his passports to leave the country. In Mexico, soon after, a bitter and badly conducted correspondence took place between the minister of foreign affairs and Mr. Shannon, our envoy. And thus, within a brief period, these two nations found themselves unrepresented in each other's capital and on the eve of a serious dispute.
