The latter made no attempt to pursue the discovery; but Ayllon, adhering to his original purpose, proceeded to Spain with Francisco,—one of the Indians, who told of a giant king and many provinces,[818]—and on the 12th of June, 1523, obtained a royal _cédula_.[819] Under this he was to send out vessels in 1524, to run eight hundred leagues along the coast, or till he reached lands already discovered; and if he discovered any strait leading to the west, he was to explore it. No one was to settle within the limits explored by him the first year, or within two hundred leagues beyond the extreme points reached by him north and south; the occupancy of the territory was to be effected within four years; and as the conversion of the natives was one of the main objects, their enslavement was forbidden, and Ayllon was required to take out religious men of some Order to instruct them in the doctrines of Christianity. He obtained a second _cédula_ to demand from Matienzo the Indians in his hands in order to restore them to their native country.[820] On his return to the West Indies, Ayllon was called on the King’s service to Porto Rico; and finding it impossible to pursue his discovery, the time for carrying out the _asiento_ was, by a _cédula_ of March 23, 1524, extended to the year 1525.[821] To secure his rights under the _asiento_, he despatched two caravels under Pedro de Quexos to the newly discovered land early in 1525. They regained the good-will of the natives and explored the coast for two hundred and fifty leagues, setting up stone crosses with the name of Charles V. and the date of the act of taking possession. They returned to Santo Domingo in July, 1525, bringing one or two Indians from each province, who might be trained to act as interpreters.[822] Meanwhile Matienzo began legal proceedings to vacate the _asiento_ granted by the King to Ayllon, on the ground that it was obtained surreptitiously, and in fraud of his own rights as joint discoverer. His witnesses failed to show that his caravel had any license to make a voyage of exploration, or that he took any steps to follow up the discovery made; but the suit embarrassed Ayllon, who was fitting out four vessels to sail in 1526, in order to colonize the territory granted to him. The armada from Spain was greatly delayed; and as he expected by it a store of artillery and muskets, as well as other requisites, he was at great loss. At last, however, he sailed from Puerto de la Plata with three large vessels,—a caravel, a breton, and a brigantine,—early in June, 1526.[823] As missionaries he took the famous Dominican, Antonio de Montesinos, the first to denounce Indian slavery, with Father Antonio de Cervantes and Brother Pedro de Estrada, of the same Order. The ships carried six hundred persons of both sexes, including clergymen and physicians, besides one hundred horses.
