The 1880s meant in the nations of the Southern Cono a census effort and the inventory and collection of objects, the results of which were shown at the universal exhibitions in Barcelona and Paris. For this purpose, the statistical expert Gabriel Carrasco travelled in 1888 through the territories of North-East Argentina and arrived in Paraguay. The comments he made during his trip were written in the form of letters, in which he posted a number of images and representations about the past and the present Paraguay. This article is responsible for studying them, using their Travel Charters as the main sources for analysis. The aim is to help make the links between expert knowledge, observation of reality, history and memory explicit, and to highlight the performance and programmatic nature of the narrative of this decimonic statistician.
