Diego de Ordaz (1531) and Alonzo de Herrera (1535) directed their journeys of discovery along the banks of the Lower Orinoco. The former is the famous Conquistador of Mexico, who boasted that he had taken sulphur out of the crater of the Peak of Popocatepetl, and whom the emperor Charles V permitted to wear a burning volcano on his armorial bearings. Ordaz, named Adelantado of all the country which he could conquer between Brazil and the coast of Venezuela, which was then called the country of the German Company of Welsers (Belzares) of Augsburg, began his expedition by the mouth of the Maranon. He there saw, in the hands of the natives, "emeralds as big as a man's fist." They were, no doubt, pieces of that saussurite jade, or compact feldspar, which we brought home from the Orinoco, and which La Condamine found in abundance at the mouth of the Rio Topayos. The Indians related to Diego de Ordaz that on going up during a certain number of suns toward the west, he would find a large rock (pena) of green stone; but before they reached this pretended mountain of emerald (rocks of euphotide?) a shipwreck put an end to all farther discovery. The Spaniards saved themselves with difficulty in two small vessels. They hastened to get out of the mouth of the Amazon; and the currents, which in those parts run with violence to the north-west, led Ordaz to the coast of Paria where, in the territory of the cacique Yuripari (Uriapari, Viapari), Sedeno had constructed the Casa fuerte de Paria. This post being very near the mouth of the Orinoco, the Mexican Conquistador resolved to attempt an expedition on this great river. He sojourned first at Carao (Caroa, Carora), a large Indian village, which appears to me to have been a little to the east of the confluence of the Carony; he then went up the Cabruta (Cabuta, Cabritu), and to the mouth of the Meta (Metacuyu), where he found great difficulty in passing his boats through the Raudal of Cariven. The Aruacas, whom Ordaz employed as guides, advised him to go up the Meta; where, on advancing towards the west, they asserted he would find men clothed, and gold in abundance. Ordaz pursued in preference the navigation of the Orinoco, but the cataracts of Tabaje (perhaps even those of the Atures) compelled him to terminate his discoveries.
