the mountains move further from the river, and the terrain becomes a uniform plain, parched or coated with grasses or cane. Here, everywhere in the plains especially after the rain, there are white crusts of salt flourishing, and the places where they are most abundant (lagoons, salines), are called "salt mines" by the inhabitants, who annually come there from near and far to collect this good of nature.

Salt plains

Many of these salt plains are far from the river, such as the following: on the eastern side, Batateira, 12 leagues, and Brejo da Brasida, 15 leagues; on the western side, the one of Brejo Seco, at seven leagues, the one of Pindoba, at four, the one at Brejo do Zacarias, at six, and the one at Sabinas Grandes, at 12 leagues; others, such as Casa Nova, are along the banks of the river. Also in the nearest neighborhood of the river are the saltpans of Sergeant, Pate, Opensus, Village, Salitre River, and Pacui and Baixa Grande, Pacui Creek, tributary of the former. The Assurua salt flats, also to the east, are four leagues from the river, and are particularly notable because they are close to a large lagoon, which communicates with the Sao Francisco River through a canal. Most of the salt flats are owned by the wealthiest ranchers on the banks of Sao Francisco; others, especially those in the west, where many regions of the desert territory have no legal owner, and where the boundaries of the salt district are barely known, can be enjoyed by those who discover them. The operation to extract salt is very simple. Salt scabs are scraped with the earth, one inch deep (for which the carnauba palm pedicle is usually used); rain or river water is the extraction of everything; the leach is immediately exposed to the action of the sun for crystallization. This is done, sometimes in wooden bowls, one for the cloudy salt solution, and one for the decanted solution and for crystallization; sometimes in a bangiie (oxhide) stretched over four stakes, with a sunken opening in the center through which the leach drips into another unpunched leather or into a trough. In order to immediately retain insoluble impurities in this latter operation, the hole is covered with palm leaf and a layer of clean sand is poured over. The crystallization pellet has a depth of foot, and receives several crusts, which precipitate as they form on the surface of the leach. In a bungalow, you get 60 to 120 pounds of salt, over a period of two to three weeks.

The leach is continued until the crystallization vessel is completely filled with salt; it is then removed, which is then broken very small, to dry completely in the sun, and it is packaged in rectangular ox leather bags (beating, beating), whose weight is 30 to
