That day and four more having passed without the return of the Indian Payaguá, the governor sent for the interpreter, and asked him what he thought of this delay. And he said that he believed the chief would certainly never make his appearance, because the Payaguás are very sly and cautious; that the chief's motive for sending an envoy to treat for peace was only to gain time and prevent the Spaniards and Guaranís from advancing and finding out the settlements of the Payaguás, and that while they (the Spaniards) were waiting the arrival of the chief, the Payaguás were removing their settlements, wives, and children, and that he thought they had fled to some place of concealment higher up the river. He advised the governor to follow, as he was certain that he would overtake them, because he knew they would be heavily loaded. In his opinion, the Payaguás would continue their flight till they reached a lagoon formerly inhabited by a tribe called the Mataraes, whom these Payaguás had slain and destroyed and had taken possession of their land because it abounded in fisheries.

The governor immediately gave orders to raise anchors, and brigantines and canoes went on navigating up the river. Wherever he halted, great numbers of the Payaguás might be seen along the bank, who, as the interpreter had said, were going by land with their wives and children, because the canoes could not contain them.
