It is not surprising that such a state of things should have worked up Vieyra’s indignation to the boiling point. He had soon an opportunity of venting his most righteous wrath from the pulpit. It was the season of Lent, and as his reputation for eloquence had preceded him, the church was, for once at least, filled to overflowing. In a discourse which has been preserved, he acted on the command given to the Prophet Isaiah, “Cry aloud, spare not, lift up thy voice like a trumpet, and show my people their transgressions.” In a passage which might perhaps be addressed from the pulpit to the Brazilians of to-day, he observes, “But you will say to me this State cannot be supported without Indians. Who is to plant our mandioc? Must our wives do it? Must our children do it? If necessity and conscience require it, I reply, ‘Yes;’ for better it is to be supported by the sweat of one’s own brow than by another’s blood.” He had no difficulty in touching by his impassioned eloquence the consciences, if not the hearts, even of the hardened congregation whom he addressed; and on the same afternoon a meeting was held, in which it was agreed to go into the history of each individual Indian who was detained in a state of slavery, and to leave each case to be decided by the Senate. A deed expressing the consent of the people to this arrangement was immediately drawn up and signed by all the chief persons of the place. Vieyra now undertook the task of instructing the Indians each Sunday; and after a time he made plans for a missionary expedition amongst the tribes. In this project, however, he had to encounter the selfishness of the governor, who could not spare from his own plantations the Indians whom Vieyra required to accompany him. Disappointed in this quarter he turned to another, only to meet with a like repulse. The results of his efforts convinced him that it was impossible to proceed with the conversion and civilization of the Indians, so long as the civil authorities should have any power over them. He accordingly wrote to the King his opinion that the governors and chief-captains should possess no authority over the Indians excepting in time of war, when a certain number should be allotted for military service; that the Indians should have an advocate in each captaincy, annually elected, and independent of the governor; that the natives should be governed by religioners; that at the beginning of each year lists should be made of the Indians in each captaincy, and likewise of the settlers, and that the former should then be divided amongst the latter by their own advocate and by the superior of the religious order; that no Indian should work for a settler for more than four months in a year, in terms of two months, their wages being deposited in advance. He added other excellent suggestions; but so urgent was the case that it was thought better that he should himself proceed to Europe vividly in order to plead in person.
