Salt was one of the first necessaries of life which became scarce on account of the blockade. The Adjutant and Inspector-General of Alabama stated, March 20, 1862, that the Confederacy needed 6,000,000 bushels of salt, and that only an enormous price would force the people to make it. In Montgomery salt was then very scarce, bringing $20 per sack, and speculators were using every trick and fraud in order to control the supply.[392] The poor people especially soon felt the want of it, and in November, 1861, the legislature passed an act to encourage the manufacture of salt at the state reservation in Clarke County.[393] The state government even began to make salt at these salt springs. At the Upper Works, near Old St. Stephens, 600 men and 120 teams were employed at 30 furnaces, which were kept going all the time, the production amounting to 600 bushels a day. These works were in operation from 1862 to 1865. The Lower Works, near Sunflower Bend on the Tombigbee River, for four years employed 400 men with 80 teams at 20 furnaces. The production here was about 400 bushels a day. The Central Works, near Salt Mountain, were under private management, and, it is said, were much more successful than the works under state management.[394] The price of salt at the works ranged from $2.50 to $7 a bushel in gold, or from $3 to $40 in currency. From 1861 to 1865, 500,000 bushels of good salt were produced each year. To obtain the salt water, wells were bored to depths ranging from 60 to 100 feet,--one well, however, was 600 feet deep,--while in the bottom or swamp lands brine was sometimes found at a depth of 8 feet. The water at first rose to the surface and overflowed about 30 gallons a minute in some wells, but as more wells were sunk the brine ceased to flow out and had to be pumped about 16 feet by steam or horse power. It was boiled in large iron kettles like those then used in syrup making and which are still seen in remote districts in the South. Seven or eight kettles of water would make one kettle of salt. This was about the same percentage that was obtained at the Onondaga (New York) salt springs. About the same boiling was required as in making syrup from sugar-cane juice. The wells were scattered for miles over the country and thousands of men were employed. For three years more than 6000 men, white and black, were employed at the salt works of Clarke County, from 2000 to 3000 working at the Upper Works alone. All were not at work at the furnaces, but hundreds were engaged in cutting and hauling wood for fuel, and in sacking and barrelling salt. It is said that in the woods the blows of no single axe nor the sound of any single falling tree could be distinguished; the sound was simply continuous. Nine or ten square miles of pine timber were cleared for fuel.
