A direct result of the murder of the Administrator was the stocking of the sertão of Minas with cattle: the entourage of the dead man, as much horrified by the deed as was Borba Gato, instead of returning to the capital took to the bush with the seeds, stores and livestock without which no expedition set out, and formed nuclei of fazendas in a score of different places. One of the earliest discoveries of gold in Brazil was made by Bartholomeu Bueno da Silva in the Serra Doirada, in Goyaz, about 1682. He it was who found the Indians wearing scraps of gold as ornament, and tricked them into showing the place of its origin; displaying a bowl of agua-ardente (aguardente—spirit made from sugarcane) he set light to it, telling the Indians that it was water and that he would in like manner set fire to all their springs and rivers if they did not reveal the source of their gold. Southey calls Bartholomeu Bueno “the most renowned adventurer of his age,” and to him is due the opening-up of Goyaz, until then only entered by passing slave-hunters: but his discoveries were not followed up and it remained for his son, nicknamed by the Indians Anhangoera the Second his father having been known to them as Old Devil the First on account of the incident referred to above, to re-find the mines and extend the gold-mining fever to Goyaz. It was in 1722 that this son, then a man of over fifty years, succeeded in obtaining government help for exploration: by this time Minas was overrun with gold seekers from every part of Brazil and the authorities were ready to give active help to new mining expeditions. This bandeira set out with great éclat, crossed the Rio Grande and wandered for three years, the leader seeking landmarks dimly remembered from his boyhood. Persistent, patient, conciliating his weary followers, he founded the town of Barra, at last located the gold mines, returned to São Paulo and got together a new band of men, led the way back and settled them at what is now the City of Goyaz, and so closed with a remarkable colonizing feat the last of the great expeditions into the high sertão.

The day of the explorer, the true bandeirante, was over, and the age of mining was by this time in its epoch of greatest excitement.
