[AS.] A substance found in the earth, and very abundant in sea-water, used for seasoning and preserving food. It is composed of sodium combined with chlorine. Salt is important as an article of food, and the lower animals like it; farmers place lumps of rock-salt in their fields for the sheep and the cows to lick. In North America there are certain places where the rocks contain much salt, and wild animals flock in great numbers to these places, which are known as " salt-licks." Salt forms solid beds in the crust of the earth, just as coal does ; and in this state it is known as rock-salt. Rain-water, sinking into the ground, dissolves much of the rock-salt; and if a well be dug down to this salt water, it can be pumped up, and the salt obtained from it by evaporation crystallizes in cube shapes. The salt water is called brine. Salt can also be obtained by evaporating sea-water. In the Carpathian Mountains there are beds of salt from 600 to 700 feet thick. Near Cracow there is a wonderful salt-mine over a thousand feet deep, divided into floors, galleries, and passages, all of salt. One division is so like a church that it is called St. Anthony's Chapel. It has an altar, pulpit, and statues. Another room has a tomb made of salt. The passages are estimated to extend 300 miles. Rock salt is abundant in many parts of the United States, and great quantities of brine are pumped up and evaporated in New York. Large deposits exist in Michigan, Louisiana, Utah, Nevada, and elsewhere.
