Addressed to his "Great and Good Friend," President McKinley's letter announces his chosen Minister Plenipotentiary to Chile, Henry L. Wilson, asserting: "He is well informed of the relative interests of the two countries and of our sincere desire to cultivate to the fullest extent the friendship which has so long subsisted between the two Governments." President McKinley then requests that President Errázuriz Echaurren "receive [Wilson] favorably and to give full credence to what he shall say on the part of the United States and to the assurances which I have charged him to convey to you of the best wishes of this Government for the prosperity of Chile."

Henry Lane Wilson (1857-1932) served as Minister to Chile from 1897-1904, Minister to Belgium from 1905-1909, and Ambassador to Mexico from 1909-1913. His notorious involvement in the February 1913 coup d'etat in Mexico, resulting in the assassination of the Mexican President and Vice President, caused President Woodrow Wilson to recall him from his post as Ambassador.
