These proposals were not accepted. Austria would agree to the first two only; France refused to denounce the trade as piracy; and Prussia was non-committal. The utmost that could be gained was another denunciation of the trade couched in general terms.[33] 70. ~Negotiations of 1823-1825.~ England did not, however, lose hope of gaining some concession from the United States. Another House committee had, in 1822, reported that the only method of suppressing the trade was by granting a Right of Search.[34] The House agreed, February 28, 1823, to request the President to enter into negotiations with the maritime powers of Europe to denounce the slave-trade as piracy; an amendment "that we agree to a qualified right of search" was, however, lost.[35] Meantime, the English minister was continually pressing the matter upon Adams, who proposed in turn to denounce the trade as piracy. Canning agreed to this, but only on condition that it be piracy under the Law of Nations and not merely by statute law. Such an agreement, he said, would involve a Right of Search for its enforcement; he proposed strictly to limit and define this right, to allow captured ships to be tried in their own courts, and not to commit the United States in any way to the question of the belligerent Right of Search. Adams finally sent a draft of a proposed treaty to England, and agreed to recognize the slave-traffic "as piracy under the law of nations, namely: that, although seizable by the officers and authorities of every nation, they should be triable only by the tribunals of the country of the slave trading vessel."[36] Rush presented this _project_ to the government in January, 1824. England agreed to all the points insisted on by the United States; viz., that she herself should denounce the trade as piracy; that slavers should be tried in their own country; that the captor should be laid under the most effective responsibility for his conduct; and that vessels under convoy of a ship of war of their own country should be exempt from search. In addition, England demanded that citizens of either country captured under the flag of a third power should be sent home for trial, and that citizens of either country chartering vessels of a third country should come under these stipulations.[37]
