Note 5 — Chapter I · THE NATURAL REGIONS OF ARGENTINA
Reading edition
F. de Azara, Diario de un reconocimiento de las guardias y fortines que guarnecen la linea frontera de Republica Argentina (1796, Coll. de Angelis, vol. vi.). The documents collected by de Angelis show clearly that there had been some idea in the middle of the eighteenth century of occupying the whole plain to the east of the Sierra de Tandil. These ideas of expansion, of which D'Azara's plan is another instance, were interrupted by the Revolution (Diario de D. Pedro Pablo Pabon, Coll. de Angelis, iv. etc.).
