Nunnez de Gusman was sent from Mexico, in 1531, with 500 soldiers, half of whom were cavalry, and 6000 Indians to carry his baggage and provisions, to discover and subdue the countries to the northwest of the kingdom of Mexico. In this expedition he reduced the countries of Xalisco, Ceintiliquipac, Ciametlan, Tovalla, Cnixo, Ciamolla, Culhuacan, and other places. On this expedition he marched through Mechuacan, where he acquired much gold, and 10,000 marks of silver. To the country of Xalisco he gave the name of New Galicia, because it was rugged and mountainous, and the people robust and hardy. He built many towns in the conquered countries; particularly Compostella, Guadalajara, after the place of his own birth in Spain, Santo Espirito de la Conception, and St Michael, which last is in lat. 24° N. In 1532, Cortes sent Diego Hurtado de Mendoça in two ships from Acapulco, which is 70 leagues from Mexico, on purpose to explore the coast of the South Sea, as he had been ordered to do by the emperor. Mendoça sailed from Acapulco to the harbour of Xalisco, or Xalis, on the river Barania, in lat. 22° N. where he wished to take in wood and water. But he was resisted there, by the orders of Nunnes de Gusman, and obliged to proceed on his voyage. Some of his men mutinied, and he put them all on board one of his ships, that they might return to New Spain. Being in want of water, these people put in at the bay of Vanderas, not far south from Xalis, where they were all slain by the Indians. In this voyage of discovery, Hurtado sailed 200 leagues along the coast, but did nothing worthy of being recorded.
