When Tupac Inca Yupanqui had become lord of the country as far as Quito, in the manner already described, and being himself still at Quito, he resolved to take steps to ensure that his orders were complied with and carried out. He, therefore, directed those who among his followers were most expert to be carried by the natives in hammocks, some to one part, some to another, overlooking and examining the condition of the new provinces, taking account of the governors and collectors of tribute, and judging of their dealings with the natives.

The Inca sent his Orej ones to the provinces which we call Puerto Viejo, to induce the inhabitants to submit, as the others had done, and to instruct them how they were to sow, to work, to dress, and to worship the Sun, and to make them understand the orderly system of living, and of policy. They relate that these Orejones were killed, as a reward for the good they came to do; and that Tupac Inca sent certain captains, with troops, to punish the murderers. But when the barbarians knew of their approach, they assembled in such numbers that they conquered and killed the Inca's troops, at which he showed anger. But as he had important affairs on his hands, and had occasion to proceed in person to Cuzco, he was not in a position to chastise them for what they had done.
