Sir: I have the honor to inform you that I have sent to the foreign office the communication of which a copy is inclosed.

The question arose, in the case of a French man-of-war which had engaged in surveying and sounding one of the closed ports, whether it was allowable for foreign officers to make such surveys. The foreign ministers, after a discussion, unanimously held that this was a treaty right. The question was presented to the yamên during my absence, and I had only to approve the conduct of my colleagues. While it is [Page 194] to be supposed that the great maritime countries of Europe might prohibit such surveys, still the case is, or ought to be, different with China. She has absolutely neglected hydrographic work, perhaps for the good reason that she had no scientific officers. She has stood by and seen the foreigner sound and make charts for all her coasts. There seems to be no good reason why she should now object to a completion of the work. It happens that we are the only nation that has a treaty which by just intendment may be held to include this subject.

The ninth article of the treaty of June 18, 1858, reads as follows:

Whenever national vessels of the United States of America, in cruising along the coast and among the ports opened for trade for the protection of the commerce of their country, or for the advancement of science, shall arrive at or near any of the ports of China, the commanders of said ships and the superior local authorities of government shall, if it be necessary, hold intercourse on terms of equality and courtesy in token of the friendly relations of their respective nations; and the said vessels shall enjoy all suitable facilities on the part of the Chinese Government in procuring provisions or other supplies and making necessary repairs.

The last clause of this article provides that our national vessels may “pursue pirates, and, if captured, deliver them over for trial and punment.”

There have been several examples of such work being done by American ships, notably that of the Wyoming in 1862 or 1863. Unless the ports shall have been sounded and surveyed, such pursuit in many cases would be impracticable. It seems to me very clear that in the interest of humanity and of commerce this right should be insisted on.

I have, etc.,

Charles Denby.

Mr. Denby to the Tsung-li yamên.

Your Highness and Your Excellencies: I have the honor to inform Your Highness and Your Excellencies that since my return to Peking I have learned that my colleagues have addressed Your Highness and Your Excellencies on the subject of permitting officers on board men-of-war to make surveys of the various ports of China.

I take this opportunity of saying that I cordially approve of the course of my colleagues. I have made four voyages on the coast of China and have just returned from one on which I traveled over 4,000 miles. Every few feet of this coast has been sounded, and accurate charts have been prepared by the officers attached to the ships of various nationalities. The value of such services to humanity and to trade and commerce can not be overestimated. These charts, together with the splendid system of light-houses and buoys organized by the inspector-general of the imperial maritime customs, have made the very dangerous coast of China easy and safe for navigation. But it will always happen that in stress of weather or on account of accidents ships will be compelled to take refuge in ports. The treaties provide that such refuge may be had. How can a ship enter a port safely which has never been surveyed or charted? The open sea, in such event, might be less dangerous than an unknown port. China has hitherto failed to do this necessary work herself. She should not, therefore, object to its being done by other nations. I call Your Highnesses and your Excellencies’ attention finally to the ninth article of the treaty of June 18, 1858, made between the United States and China, wherein it is distinctly provided that the vessels of the United States may visit any of the ports of China. The last clause provides that the national vessels of the United States may pursue and capture pirates. There have been several cases of the pursuit and capture of pirates by American ships. How can this work, which is thus distinctly specified, be done unless the various ports are properly sounded and surveyed in advance? In the interest of humanity, as well as of commerce, Chinese and foreign, I hope that Your Highness and Your Excellencies will see your way clear to the approval of the right of foreign scientific officers to continue and complete the hydrography of all the ports of China.
