The Chargé in Canada (Boal) to the Secretary of State

No. 533

Sir: I have the honor to refer to the Department’s instruction No. 300 of April 14, 1934, relative to the Trail Smelter question, and to report that in compliance therewith I have addressed a note to the Canadian Department of External Affairs embodying the observations set forth in the Department’s instruction No. 259 of March 14, 1934. In view of subsequent developments I thought it advisable to omit from my note to the Canadian government the observations contained in the final paragraph on page 14 of the Department’s instruction No. 259.

Respectfully yours,

Pierre de L. Boal
