By a convention signed November 20, 1894, the Mosquito Indians surrendered their rights under the treaty of 1860 and were incorporated with Nicaragua. This voluntary incorporation took away all further occasion for interposition on the part of Great Britain, and Mr. Bayard reported that it was received with "the most open expression of satisfaction at the foreign office."[180] The attempts of Blaine and Frelinghuysen to bring about a modification of the Clayton-Bulwer treaty were, as we have seen, unsuccessful. In fact, their only effect was to strengthen the British government for the time being in the determination to hold us more strictly to the terms of that convention. In 1896 Secretary Olney in a review of the situation declared: Upon every principle which governs the relations to each other, either of nations or of individuals, the United States is completely estopped from denying that the treaty is in full force and vigor. If changed conditions now make stipulations, which were once deemed advantageous, either inapplicable or injurious, the true remedy is not in ingenious attempts to deny the existence of the treaty or to explain away its provisions, but in a direct and straightforward application to Great Britain for a reconsideration of the whole matter.[181] It was precisely in this spirit that Secretary Hay undertook in 1899 to negotiate a new treaty with England. The original draft of the Hay-Pauncefote treaty, signed February 5, 1900, provided for a neutralized canal and drafted for its control rules substantially in accord with the Constantinople convention of 1888, providing for the regulation of the Suez canal. The most important provision of the new treaty was that authorizing the United States to construct and to assume the management of an isthmian canal, either directly or through a company. The United States Senate, however, amended the treaty in three important particulars: (1) by declaring that the Clayton-Bulwer treaty was thereby superseded; (2) by providing that the restrictions in the regulations governing the use of the canal should not apply to measures which the United States might adopt for its own defense and for the maintenance of public order along the canal; and (3) by cutting out entirely the article providing for the adherence of other powers. The British government refused to accept these amendments, and a year elapsed before an agreement was finally reached.[182] The revised treaty which was ratified by the Senate December 16, 1901, was a compromise between the original draft and the Senate amendments. The new treaty abrogated in express terms the Clayton-Bulwer convention, and provided that the United States might construct a canal under its direct auspices, to be under its exclusive management. The principle of neutralization was nominally retained, but under the sole guarantee of
