In the year 1537, John de Vadillo, the governor of Carthagena, went with a powerful armament from the port called _St Sebastian de Buena Vista_, in the gulf of Uraba, to the Rio Verde, whence he went by land, without previously knowing any part of the way, and without carriages, to the very extremity of Peru and the town of La Plata, a distance of 1200 leagues, a most memorable journey. The whole country, from the Rio Verde to the mountains of Abibe, is full of rugged hills, thick forests, and many rivers, through which they had to pierce their way with infinite toil. The mountains of Abibe are said to be twenty leagues broad, and can only be passed over in the months of January, February, March, and April, as from incessant heavy rains at all other times of the year, the rivers are so swelled as to be quite impassable. In these mountains there are many herds of swine, many dantes, lions, tigers, bears, ounces, large wild-cats, monkeys, vast snakes, and other vermin. There are also abundance of partridges, quails, turtle-doves, pigeons, and other birds of many different kinds. The rivers also were so full of fish that they killed them with staves; and they affirmed, if they had been provided with rods and nets, that a very large company of men might be subsisted, without ever being in distress for want of food. In this expedition they noted the diversities of people, languages, dress, and other circumstances, during the whole way, through many countries, kingdoms, and, provinces, and the great difficulties and dangers they encountered till their arrival at the _Villa de la Plata_, and the adjoining sea. This was the most extensive discovery which has been ever heard of by land, and in so short a time; insomuch that, if it had not been performed in our own days, it could hardly have been credited[84]. In 1538, certain friars of the order of St Francis went from Mexico to preach to the natives in the northern part of New Spain, and to convert them to the Catholic faith. One Mark de Nizza penetrated farther than any of the rest.--Passing through Culvacan, or Culiacan, he came into the province of Sibola, or Cinaloa, where he pretended to have found seven cities, and that the farther he went the richer was the country in gold, silver, and precious stones, with many sheep bearing wool of great fineness. On the fame of this wealth, the viceroy Don Antonio de Mendoça, and Cortes, determined to send a force to take possession of the country; but, as they could not agree on this subject, Cortes and his wife went over to Spain in 1540, where he died seven years afterwards[85].
