I left Bahía Negra by air for Corumbá (Brazil) on November 24. From Corumbá I proceeded by motor-car to Puerto Suarez, where I met the Bolivian General Mariaca Pando. He was not expecting me, as he had not then received any instructions from his Government regarding my visit. Nevertheless, he showed himself quite ready to furnish me, very courteously, with information of every kind. After passing the whole day at Puerto Suarez, I returned in the evening to Corumbá. The next morning I resumed my journey by air to Puerto Casada, where I rejoined the other members of the Commission.
