Correspondencia Oficial e Inedita sobre la Demarcacion de Limites entre el Paraguay y el Brasil

In this compelling collection of letters and reports, a 19th‑century commissioner records the painstaking effort to draw the frontier between a South‑American province and its Brazilian neighbour. The documents reveal how treaty language, vague river names and uncertain maps turned the simple act of drawing a line into a tangled web of diplomatic argument. Readers hear the meticulous observations of a man determined to locate the true courses of the Yguareí and Appa rivers, correcting earlier mistakes that had left the boundary hanging in limbo.

The correspondence also lays bare the personal and political friction that accompanied the survey. The commissioner’s sharp critique of Portuguese officials, his accusations of corruption against the regional governor, and the stubborn resistance of colonial authorities give the narrative a vivid, human edge. Through candid exchanges, the letters expose the clash of ambition, bureaucracy and the harsh realities of frontier life.

Listening to these papers offers a rare glimpse into the early geopolitics of the continent, where geography, power and personality collided. The voice of a determined explorer brings history to life, making the struggle over borders feel immediate and resonant.
