The chart made by the Institutes Geoaraphicos rilitores of Uruguay and
Aroentina concerning the river Uruguay, which was nublished in 1949, marks portions
of Urugueyan and Argentine territories including the river. This chart was made by

from Rio Cutrein to 10 Tnilometers south of the mouth of Arroyo Chapicuy Chico.
Other In)ntions of both territories and Rio Uruguay over Paysandu and Rio negro are
registered in air p,:otogranhical stereoscopic pairs to scales 1:20,000 and 1:33,000

Urranny is registered is over two and one.helf centuries old. The first napcien on
