The International Meridian Conference lately convened in Washington upon the invitation of the Government of the United States was composed of representatives from twenty-five nations. The conference concluded its labors on the 1st of November, having with substantial unanimity agreed upon the meridian of Greenwich as the starting point whence longitude is to be computed through 180 degrees eastward and westward, and upon the adoption, for all purposes for which it may be found convenient, of a universal day which shall begin at midnight on the initial meridian and whose hours shall be counted from zero up to twenty-four. The formal report of the transactions of this conference will be hereafter transmitted to the Congress. This Government is in frequent receipt of invitations from foreign states to participate in international exhibitions, often of great interest and importance. Occupying, as we do, an advanced position in the world's production, and aiming to secure a profitable share for our industries in the general competitive markets, it is a matter of serious concern that the want of means for participation in these exhibitions should so often exclude our producers from advantages enjoyed by those of other countries. During the past year the attention of Congress was drawn to the formal invitations in this regard tendered by the Governments of England, Holland, Belgium, Germany, and Austria. The Executive has in some instances appointed honorary commissioners. This is, however, a most unsatisfactory expedient, for without some provision to meet the necessary working expenses of a commission it can effect little or nothing in behalf of exhibitors. An International Inventions Exhibition is to be held in London next May. This will cover a field of special importance, in which our country holds a foremost rank; but the Executive is at present powerless to organize a proper representation of our vast national interests in this direction. I have in several previous messages referred to this subject. It seems to me that a statute giving to the Executive general discretionary authority to accept such invitations and to appoint honorary commissioners, without salary, and placing at the disposal of the Secretary of State a small fund for defraying their reasonable expenses, would be of great public utility. This Government has received official notice that the revised international regulations for preventing collisions at sea have been adopted by all the leading maritime powers except the United States, and came into force on the 1st of September last. For the due protection of our shipping interests the provisions of our statutes should at once be brought into conformity with these regulations.
