the first edition of "facundo" was published in instalments in 1845, in the literary supplement of the chilean newspaper "el progreso". the second edition, also published in chile (in 1851), contained significant alterations—sarmiento removed the last two chapters on the advice of valentín alsina, an exiled argentinian lawyer and politician. however the missing sections reappeared in 1874 in a later edition, because sarmiento saw them as crucial to the book's development.
