To-day, luncheon here for Mlle. de Tréville, the singer, and her mother, who are the guests of the ambassador. We all miss dear Mrs. Wilson, who has returned suddenly to the States on account of the illness of her son, Warden, at Cornell. Rieloff was among the guests and we are to dine there on Saturday and have a musical evening afterward. He was consul-general in Hong-Kong when Von Hintze was out there as lieutenant on Prince Henry's staff. Now, what the Mexicans would call their _categoría_ is reversed. _April 11th._ I do hope, though probably vainly, that Madame Madero doesn't see _all_ the dreadful caricatures appearing about her husband. _El Mañana_, edited by an extremely clever Porfirista, has apparently set out to grind him to powder, and there is one, _El Multicolor_, edited by a Spaniard, sometimes quite ribald, which I should say is preparing to bury the remains with scant ceremony. There was a cartoon the other day, which I am sending, representing Madero being kicked down a long, broad flight of stairs in the palace on to a transatlantic liner bearing the fateful name _Ypiranga_,[43] the historic ship that bore Diaz across the bitter waters. The Latin-American mind is at its best in satire, and with the dart well poisoned they kill off their public men by the dozens. _April 14th._ The Mexican government is decidedly upset to-day at the receipt of a notification from Washington to the effect that the United States will hold Mexico and the Mexican people responsible for illegal acts sacrificing or endangering American life or property. It is a simultaneous warning to both Madero and Orozco, and the _bon mot_ of the situation here is, "Is necessity the mother of in_ter_vention?" _April 16th._ I am still numbed and dazed by the reading of the _Titanic_ catastrophe. _April 17th._ The Mexican government replies to our notification of the 14th, first cousin to an ultimatum, in which we call categoric attention to the enormous destruction of American property, ever on the increase in Mexico, and the taking of American life, contrary to the usages of civilized nations. The United States expects and demands that American life and property within the Republic of Mexico be justly and adequately protected, and will hold Mexico and the Mexicans responsible for all wanton and illegal acts sacrificing or endangering them.
