In 1526 Sebastian Cabot left Spain with three small vessels and a caravel for the object of reaching the Moluccas or Spice Islands. It was his purpose to reach them through the Straits of Magellan. Being compelled by want of supplies to abandon his route, he entered a broad estuary, and ascended it under the impression that he had discovered another channel to the Pacific. He soon found his mistake, and began to explore the surrounding country. Fifteen years before, with the same object, Juan de Solis had entered the same estuary. On the island of Martin Garcia he was killed by a Chana Indian, and his expedition returned home. Hearing that there was much silver at the head-waters, he had called it the Rio de la Plata. If we take the head-waters of the river Plate to be situated in Bolivia, there certainly was much silver there; but Cabot was unaware that the head-waters were above two thousand miles from the estuary, and he was not destined to come near them. He did go as far as a point on the river Caracara, in what is now the province of Santa Fé, and there he built a fort which he named Espiritu Santo, the first Spanish settlement in that part of America. Whilst at Espiritu Santo, several exploring parties were sent to scour the country. One of them, under a soldier of the name of Cesar, never returned. Tradition, always eager to make up to history for its want of interest, asserted that after marching for years they reached a city. Perhaps it was the mystic Trapalanda of which the Gauchos used to discourse at night when seated round a fire of bones upon the pampa. Perhaps some other, for enchanted cities and Eldorados were plentiful in those days in America, alternating with occasional empires, as that of Puytita, near the Laguna de los Xarayes, Manoa, and the Ciudad de los Cesares, supposed to be situated near Arauco in the Chilian Andes. However, one of the party actually returned after years, and related his adventures to Ruy Diaz de Guzman,[16] the first historian of Paraguay. Thus it was that the stream of adventurers was ever seeking for a channel to the mines of Peru from the Atlantic coast. Cabot appears to have ascended the Paraná to the island of Apipé, and then, returning, entered the river Paraguay. Having ascended past what is now Asuncion, the capital of Paraguay, Cabot encountered Indians from the north who told him of the mines in Peru and in Bolivia, probably unaware that Cabot knew of them already. At this point, encouraged by what he heard, he gave the name of Rio de la Plata to what had previously been known either as La Mar Dulce or El Rio de Solis. Like most names which are wrongly given, it remained to testify to the want of knowledge of the giver. Four years after, Cabot returned to Spain, having failed to attract attention to his discoveries. In the face of the wealth which was pouring in from the Peruvian mines, another expedition started for the river Plate. Its General—for in Spain the
