The Governor responded in a kind manner, and was then conducted to the chief's own house, prepared for his accommodation. The confluence of the Oostanaula and Etowa at this point forms the Coosa. Here De Soto remained for a fortnight, recruiting his wearied men and his still more exhausted horses. It was bright and balmy summer, and the soldiers encamping in a luxuriant mulberry grove a little outside of the town, enjoyed, for a season, rest and abundance. De Soto, as usual, made earnest inquiries for gold. He was informed that about thirty miles north of him there were mines of copper, and also of some metal of the color of copper, but finer, brighter, and softer; and that the natives sometimes melted them together in their manufacture of barbs, spearheads, and hatchets. This intelligence excited De Soto with new hopes. He had occasionally met on his way natives with hatchets composed of copper and gold melted together. As the province, which was called Chisca, was separated from Chiaha by a pathless wilderness which horses could not traverse, De Soto sent two of his most trusty followers on an exploring tour through the region, conducted by Indian guides. After an absence of ten days they returned with the disappointing report that they found nothing there but copper of different degrees of purity. The rivers in the vicinity of Chiaha seem to have abounded with pearl oysters, and large numbers of beautiful pearls were obtained. The natives nearly spoiled them all by boring them through with a red-hot rod, that they might string them as bracelets. One day the Cacique presented De Soto with a string of pearls six feet in length, each pearl as large as a filbert. These gems would have been of almost priceless value but for the action of fire upon them. De Soto expressed some curiosity to see how the pearls were obtained. The Cacique immediately dispatched forty canoes down the river to fish during the night for pearl oysters. In the morning De Soto accompanied the Cacique to the banks of the river where the oysters were collected. Large fires were built, and the oysters placed upon the glowing coals. The heat opened them, and the pearls were sought for. From some of the first thus opened ten or twelve pearls were obtained, about the size of peas. They were all, however, more or less injured by the heat. Col. Pickett says that the oyster mentioned was the muscle, to be found in all the rivers of Alabama.
