To the Senate and House of Representatives:
The act of Congress approved July 9, 1888, "for an international marine conference to secure greater safety for life and property at sea," and in virtue of which the present conference is now holding its sessions at Washington, provides by the third section that the labors of the conference shall terminate on the 1st day of January, 1890, or sooner, by direction of the President.
'I transmit herewith a report from the Acting Secretary of State, accompanied with a letter from Rear-Admiral S. R. Franklin, United States Navy, president of the conference, stating that in all probability the labors of the conference can not be brought to a close by the time fixed by the present law.
In consideration of the many important questions now under discussion by the conference, which should if possible be satisfactorily determined before the final adjournment, I earnestly recommend that a further act be passed to enable the conference to continue its sessions for a period of two months from January 1, 1890.
