This treaty, like the treaty with Colombia of 1846 and the Clayton-Bulwer treaty, contemplated the neutralization of the canal. It in no way infringed our engagements with England under the Clayton-Bulwer treaty, but in providing for the joint guarantee of other powers, was in accord with the provisions of that treaty.
In 1873, Mr. Hamilton Fish directed General Schenck to remonstrate, if upon investigation he found it to be necessary, against British encroachments upon the territory of Guatemala as an infringement of the Clayton-Bulwer treaty.[166]
In spite of the doubts expressed by Mr. Seward in the dispatch to Mr. Adams above quoted, as to the perpetual character of the obligations imposed by the Clayton-Bulwer treaty, the obligatory force of that instrument after the readjustment of 1860 was not seriously questioned until interest in the canal question was suddenly aroused anew by the concession granted by Colombia to Lieutenant Wyse in 1878, and the subsequent organization of a French construction company under the presidency of Ferdinand de Lesseps, the promoter of the Suez canal.
The prospect of the speedy construction of a canal under French control, for which De Lesseps' name seemed a sufficient guarantee, produced a sudden and radical change of policy on the part of the United States. In a special message to Congress, March 8, 1880, President Hayes made the following statement of what he conceived to be the true policy of this country in regard to a Central American canal:
The policy of this country is a canal under American control. The United States cannot consent to the surrender of this control to any European power, or to any combination of European powers. If existing treaties between the United States and other nations, or if the rights of sovereignty or property of other nations stand in the way of this policy—a contingency which is not apprehended—suitable steps should be taken by just and liberal negotiations to promote and establish the American policy on this subject, consistently with the rights of the nations to be affected by it.
The capital invested by corporations or citizens of other countries in such an enterprise must, in a great degree, look for protection to one or more of the great powers of the world. No European power can intervene for such protection without adopting measures on this continent which the United States would deem wholly inadmissible. If the protection of the United States is relied upon, the United States must exercise such control as will enable this country to protect its national interests and maintain the rights of those whose private capital is embarked in the work.
An interoceanic canal across the American isthmus will essentially change the geographical relations between the Atlantic and Pacific coasts of the United States, and between the United States and the rest of the world. It will be the great ocean thoroughfare between our Atlantic and our Pacific shores, and virtually a part of the coast-line of the United States. Our merely commercial interest in it is greater than that of all other countries, while its relation to our power and prosperity as a nation, to our means of defense, our unity, peace, and safety, are matters of paramount concern to the people of the United States. No other great power would, under similar circumstances, fail to assert a rightful control over a work so closely and vitally affecting its interests and welfare.
Without urging further the grounds of my opinion, I repeat, in conclusion, that it is the right and the duty of the United States to assert and maintain such supervision and authority over any interoceanic canal across the isthmus that connects North and South America as will protect our national interests. This I am quite sure will be found not only compatible with, but promotive of, the widest and most permanent advantage to commerce and civilization.[167]
The message itself was accompanied by a report from the secretary of state, Mr. Evarts, in which he called attention to the mutual engagements entered into between the United States and Colombia by the treaty of 1846 in reference to a transit route across the isthmus and declared that the guarantee of the neutrality of the isthmus and of the sovereignty of Colombia over the same would be a very different thing when the isthmus should be opened to the interests and ambitions of the great commercial nations.[168]
President Garfield, in his inaugural address, approved the position taken by his predecessor on the canal question,[169] and very soon after assuming the portfolio of state, Mr. Blaine outlined the new policy to our representatives in Europe, cautioning them, however, against representing it as the development of a new policy and affirming that it was "nothing more than the pronounced adherence of the United States to principles long since enunciated by the highest authority of the government."
