 in the negotiation; and on August 9, 1842, the treaty of Washington was ratified by the senate. By this treaty the boundary dispute, which had lasted fifty years, was happily adjusted. An amicable and efficient arrangement was made for joint action in the suppression of the slave-trade, and an agreement entered into for a mutual extradition of fugitives from justice. The other subjects of discussion at that period, between Great Britain and the United States, with the exception of the Oregon boundary, were happily disposed of in the correspondence accompanying the treaty. The terms of this important treaty were equally honorable and satisfactory to both parties. Mr. Tyler's cabinet was broken up in 1842, but Mr. Webster remained in office till the spring of 1843, being desirous of putting some other matters connected with our foreign relations in a prosperous train. Steps were taken by him in the winter of 1842-'3, which led to the recognition of the independence of the Sandwich islands by the principal maritime powers. His last official act was the preparation of the instructions of General C. Cushing, as commissioner for negotiating a treaty with China. With the commencement of Mr. Polk's administration, Mr. Webster returned to the senate of the United States. He remained a member of that body during the whole of the administration of Mr. Polk, and till the death of General Taylor. Though unconnected with the executive government, he rendered the most material service in the settlement of the Oregon dispute. It has been publicly stated by Mr. M'Gregor, the distinguished member of parliament for Glasgow, that a letter written to him by Mr. Webster, and shown to the British ministers, led them to agree to the adoption of the line of boundary which was established in 1846. Mr. Webster opposed the Mexican war on principle; and in the full persuasion, which events have confirmed, that acquisitions of territory would disturb the balance of the Union, and endanger its stability. He, however, concurred in granting the supplies which were required for the efficient conduct of the war. His second son, Major Edward Webster, with the entire approbation of his father, accepted a commission in the Massachusetts regiment of volunteers, and sunk under the exposures of the service in Mexico. He was a young man of great promise. In conformity with Mr. Webster's anticipations, the acquisition of Mexican territory led to agitations on the subject of slavery, which, during the years 1849-'50, seriously threatened the Union. The question whether slavery should exist in California seemed likely to lead to the renewal of the Missouri controversy, aggravated by all the bitterness which has grown out of the struggles of the last fifteen years. Mr. Webster entertained the most serious apprehensions of an inauspicious result. The convention of the people of California having unanimously adopted a constitution by which that question was disposed of, without the interference of congress, Mr. Webster conceived the hope that, by mutual concession on other and less important points, the harmony of the South and North could be restored, and a severance of the Union averted. With a view to this consummation, he made his great speech of March 7, 1850. A very powerful influence was exerted by this speech on the public mind. While the debates on what have been called the 'compromise measures' were in progress in the senate, General Taylor died. The chair of state was assumed by President Fillmore, who immediately called Mr. Webster to the department of state. His administration of the office was marked
