Excellency: I have the honor to acknowledge with thanks the receipt of your note No. 4224 of September 17, 1937,1 transmitting a copy of the treaty, with annexed maps, in French and English, signed between the Governments of Belgium and Great Britain delimiting that portion of the boundary between Tanganyika Territory and Ruanda Urundi which is situated along the Kagara River, as defined [Page 940] by the Council of the League of Nations, with a view to introducing with the consent of the Council of the League of Nations, under Article 12 of the mandate of East Africa and under Article 12 of the mandate of Ruanda Urundi, such minor modifications in the boundary as so defined as might seem desirable in view of the local geographical conditions.
You state that this treaty was submitted to the Council of the League of Nations and was approved by the latter on the approval of the Mandate Commission by a resolution dated September 6, 1935.5
The Government of the United States takes note of this treaty without prejudice to any rights which it may have in the territory affected, under the treaty and protocol between the United States of America and Belgium, signed at Brussels on April 18, 1923, and January 21, 1924, and the convention between the United States of America and Great Britain signed at London on February 10, 1925.
