Our country offers two large development areas: Northern area, which has developed itself in answer to foreign market demand, with its center located at Buenos Aires port, with reference to which are analyzed attempts of division by BUNGE, LLORENS and GARCÍA MATA, MOYANO LLERENA, MARCENARO and LLORENS. Southern area, a group of spaces almost parallel, cordillera to sea, ordinate by the transversal disposition of valleys, rivers, mountains, railways, and roads, ordination that confirms the opinions of former Minister RAMOS MEXIA, General SAROBE and the geographer and naturalist FRENGUELLI, CABRERA and FERUGLIO.
