A petition to protect two persons that have to pass thru Durango. A letter to Aguero asking for help on a military injustice, (people have been sent to Obraje). A letter from an obrero in the Obraje relating terrible conditions that they are suffering, Aguero answers he can't take part in military affairs being a civil servant and remits the letters to Croix. Letters to and from Aguero in which he and some other citizens complain about the injustice done by Lope de Cuellar, a capitan in charge of everything. Aguero has been stripped from any authority by the viceroy himself. These letters, Aguero complains, are not delivered either. Finally he is going back to Castilla but he can't get Croix to sign his papers in time to catch the ship from Veracruz, because of some discrepancies in his title and salary, he refuses to pay for his residencia while Croix keeps finding new acusations; such as depriving him of authority over administrators of the Hospital in Durango. Aguero is reduced to poverty, living with his family in a hacienda owned by some friends. Aguero defends himself with letters, which Croix refuses to answer. He is granted permission to leave for Spain only after he pays for his residencia. (T. Kahana. October 1988)
