Investigates Regarding Pearl Islands. He reached Vacapa (now known as Matapa), in Central Sonora, two days before Passion Sunday, which in 1539 fell on March 23. From this point he sent to the seacoast for some Indians, in order that he might learn from them something about the pearl islands, of which rumors had come to Cabeza de Vara. He remained here until April 6.

Stephen, the Guide, Is Sent Ahead. In the meantime, Stephen had pushed on to the north, leaving on Passion Sunday, with orders from Fray Marcos not to go further than fifty or sixty leagues ahead. If he found any signs of a rich and populous country before he had gone that distance, he was not to proceed further, but was to return for Marcos, or remain, and send messengers for him, bearing a white cross the size of the palm of his hand. If the news was very promising, the cross was to be twice the size, and if the country about which he heard promised to be larger and better than New Spain (as Mexico was then generally known), a cross still larger than this was to be sent back. Castaneda says that Stephen was sent on ahead because he and Marcos did not agree well, the negro not only showing covetousness and the determination to acquire the turquoises of the natives, but also an amorousness that demanded of them their youngest and prettiest women.
