The renowned work Observations on the Present State of the Affairs of the River Plate is crucial for historical literature. The problem of determining the borders of Spanish and Portuguese territories, notably in the Uruguay-Argentina region, is the subject of the book. The canal loading plan was considered by the Commissioner appointed under the Treaty of San Ildefonso in 1778. In addition, those were issues like the Montevideo government's desire to maintain its affordable silver currency despite all of its challenges and the Buenos Aires government's extensive paper printing. The author uses information and papers that were gathered to go into great detail about everything from their perspective.
