"In conformity with the provisions of Articles Three and Nine of the treaty of peace between Japan and Russia of this date the undersigned plenipotentiaries have concluded the following additional articles:
"Sub-Article to Article Three—The Imperial Governments of Japan and Russia mutually engage to commence the withdrawal of their military forces from the territory of Manchuria simultaneously and immediately after the treaty of peace comes into operation, and within a period of eighteen months after that date the armies of the two countries shall be completely withdrawn from Manchuria except from the leased territory of the Liao-tung peninsula. The forces of the two countries occupying the front positions shall first be withdrawn.
"The high contracting parties reserve to themselves the right to maintain guards to protect their respective railway lines in Manchuria. The number of such guards shall not exceed fifteen per kilometer, and within that maximum number the commanders of the Japanese and Russian armies shall by common accord fix the number of such guards to be employed as small as possible while having in view the actual requirements.
"The commanders of the Japanese and Russian forces in Manchuria shall agree upon the details of the evacuation in conformity with the above principles and shall take by common accord the measures necessary to carry out the evacuation so soon as possible and in any case no later than the period of eighteen months.
"Sub-Article to Article Nine—So soon as possible after the present treaty comes into force, a commission of delimitation composed of an equal number of members is to be appointed respectively by the two high contracting parties which shall on the spot mark in a permanent manner the exact boundary between the Japanese and Russian possessions on the Island of Sakhalin. The commission shall be bound so far as topographical considerations permit to follow the fiftieth parallel of north latitude as the boundary line, and, in case any deflections from that line at any points are found to be necessary, compensation will be made by correlative deflections at other points. It shall also be the duty of said commission to prepare a list and a description of the adjacent islands included in the cession, and finally the commission shall prepare and sign maps showing the boundaries of the ceded territory. The work of the commission shall be subject to the approval of the high contracting parties.
"The foregoing additional articles are to be considered ratified with the ratification of the treaty of peace to which they are annexed.
"Portsmouth, the Fifth Day of the Ninth Month of the Thirty-eight year of Meiji, corresponding to the Twenty-third of August, 1905. (September 5, 1905.)
"In witness whereof the respective plenipotentiaries have signed and affixed seals to the present treaty of peace.
"Done at Portsmouth, New Hampshire, this Fifth day of the Ninth Month of the Thirty-eighth Year of the Meiji, corresponding to the Twenty-third day of August, One Thousand Nine Hundred and Five."

Its text reads as follows:
