The Secretary of State to the Chargé in Mexico ( Johnson )
134. Your 93, May 17, noon.51 In order that we may make the necessary arrangements it is essential that we be informed earliest moment possible whether Mexican Government is agreeable to the initiation of negotiations in Mexico City some time early in July. As stated in the Department’s 12752 Department proposes to instruct Lawson to be in Mexico City for that purpose. We also hope that Mexican Boundary Commissioner will likewise be present for the discussion of technical questions.
Please take this matter up with Foreign Office immediately and telegraph.
