Note 129 — Chapter VIII · THE RIVER-ROUTES
Reading edition
The secondary arms of the right bank, north of Santa Fé, were not explored until 1870. Sullivan's map (1847) only mentions the Riacho de San Jeronimo, which is visible for a short distance below 20° S. lat. The right bank was the domain of the Indians, and the Correntinos would not venture near it. In 1870 ships began to use the San Javier arm, on which many colonies arose. Further north the Paraná Mini has been used since 1890 for exporting quebracho timber.
