Porto de Corumbá, on the banks of the Rio Paraguai, in a postcard mailed in
1905 with the following message for Miss B. Jacob, of Neuchâtel, Switzerland:
Corumbá is the capital of an immense Brazilian province, partially unexplored
and unknown, that contains incalculable riches in gold, diamonds, and rubber,
but these, unfortunately, are accompanied by a few inconveniences:
wild beasts,  alligators, and above all by deadly fevers.
