nation it did not exceed imprisonment, fine and loss of his vessel. Summed up in terms of governmental attitude the British contention was that here was a great international humanitarian object frustrated by an absurd American sensitiveness on a point of honour about the flag. After fifteen years of dispute Great Britain offered to abandon any claim to a right of _search_, contenting herself with a right of _visit_, merely to verify a vessel's right to fly the American flag. America asserted this to be mere pretence, involving no renunciation of a practice whose legality she denied. In 1842, in the treaty settling the Maine boundary controversy, the eighth article sought a method of escape. Joint cruising squadrons were provided for the coast of Africa, the British to search all suspected vessels except those flying the American flag, and these to be searched by the American squadron. At once President Tyler notified Congress that Great Britain had renounced the right of search. Immediately in Parliament a clamour was raised against the Government for the "sacrifice" of a British right at sea, and Lord Aberdeen promptly made official disclaimer of such surrender. Thus, heritage of the War of 1812 right of search in time of peace was a steady irritant. America doubted somewhat the honesty of Great Britain, appreciating in part the humanitarian purpose, but suspicious of an ulterior "will to rule the seas." After 1830 no American political leader would have dared to yield the right of search. Great Britain for her part, viewing the expansion of domestic slavery in the United States, came gradually to attribute the American contention, not to patriotic pride, but to the selfish business interests of the slave-holding states. In the end, in 1858, with a waning British enthusiasm for the cause of slave trade suppression, and with recognition that America had become a great world power, Britain yielded her claim to right of search or visit, save when established by Treaty. Four years later, in 1862, it may well have seemed to British statesmen that American slavery had indeed been the basic cause of America's attitude, for in that year a treaty was signed by the two nations giving mutual right of search for the suppression of the African Slave Trade. In fact, however, this was but an effort by Seward, Secretary of State for the North, to influence British and European opinion against the seceding slave states of the South. The right of search controversy was, in truth, ended when American power reached a point where the British Government must take it seriously into account as a factor in general world policy. That power had been steadily and rapidly advancing since 1814. From almost the first moment of established independence American statesmen visualized the separation of the interests of the western continent from those of Europe, and planned for American leadership in this new world. Washington, the first President, emphasized in his farewell address the danger of entangling alliances with Europe. For long the nations of Europe, immersed in Continental wars, put aside their rivalries in this new world. Britain, for a time, neglected colonial expansion westward, but in 1823, in an emergency of European origin when France,
