Excepting in those cases where, from reasons of contiguity of territory and the existence of a common border line incapable of being guarded, reciprocal commercial treaties may be found expedient, it is believed that commercial policies inducing freer mutual exchange of products can be most advantageously arranged by independent but cooperative legislation. In the mode last mentioned the control of our taxation for revenue will be always retained in our own hands unrestricted by conventional agreements with other governments. In conformity also with Congressional authority, the maritime powers have been invited to confer in Washington in April next upon the practicability of devising uniform rules and measures for the greater security of life and property at sea. A disposition to accept on the part of a number of the powers has already been manifested, and if the cooperation of the nations chiefly interested shall be secured important results may be confidently anticipated. The act of June 26, 1884, and the acts amendatory thereof, in relation to tonnage duties, have given rise to extended correspondence with foreign nations with whom we have existing treaties of navigation and commerce, and have caused wide and regrettable divergence of opinion in relation to the imposition of the duties referred to. These questions are important, and I shall make them the subject of a special and more detailed communication at the present session. With the rapid increase of immigration to our shores and the facilities of modern travel, abuses of the generous privileges afforded by our naturalization laws call for their careful revision. The easy and unguarded manner in which certificates of American citizenship can now be obtained has induced a class, unfortunately large, to avail themselves of the opportunity to become absolved from allegiance to their native land, and yet by a foreign residence to escape any just duty and contribution of service to the country of their proposed adoption. Thus, while evading the duties of citizenship to the United States, they may make prompt claim for its national protection and demand its intervention in their behalf. International complications of a serious nature arise, and the correspondence of the State Department discloses the great number and complexity of the questions which have been raised. Our laws regulating the issue of passports should be carefully revised, and the institution of a central bureau of registration at the capital is again strongly recommended. By this means full particulars of each case of naturalization in the United States would be secured and properly indexed and recorded, and thus many cases of spurious citizenship would be detected and unjust responsibilities would be avoided.
