English: Spanish historian Patricio Ibarra Cifuentes writes: '"El Maestro ciruela [literally The Plum Master] giving an international law class" is the title of this cartoon published by El Padre Cobos on October 13, 1881. Regarding the open intervention of the United States in favor of Peru in the negotiations to end the War of the Pacific, personified in his representative in Peru. Stephen Augustus Hurlbut, El Padre Cobos and el Negro punish Uncle Sam in a class of international law: the first pulls an ear while his partner places a dunce cap which reads "for intruding". Uncle Sam, identified as named as Mr. Hurlbut, tells El Padre Cobos that Peru has already lost its honor so nothing else remains to be lost, to which Uncle Sam replies that he still has to disappear completely. Students include, among others, Diego Barros Arana, Miguel Luis Amunátegui, José Manuel Balmaceda, José Victorino Lastarria and Máximo R. Lira who make astonished gestures. The drawing is an open criticism of the participation of the United States in the liquidation of the war and the lenity of Chilean politicians to defend their interests, according to the newspaper's point of view. Here is public opinion, embodied by Father Cobos and Negro, who face the adversaries of the Fatherland.'
