Common salt is found in two forms –liquid and cold. Sea-water is full of salt, and in some places brine-springs, or salt –springs flow out of rock like ordinary streams. And salt is also solid, like rock, and is dug out of the ground, as coal is, by mining. This form of salt is called rick-salt. There are famous salt-mines in the salt range in Punjab, which are worked by government.

Salt is also got out of the sea. The sea water is let into shallow pools on the shore, and is left there until the water goes off into the air in vapor, and leaves the while, salt crystals at the bottom. The salt is then gathered and as it is mixed with sand and mud, it is put into large pans and washed, and then is melted again in clean water. This water is heated, and goes off in steam, leaving the pure white salt behind.

Salt has a wonderful power of keeping things from going bad. Fish or meat kept in salt will keep good for a long time. Ham and bacon boiled in salt water and kept in brine (liquid salt) for weeks, will keep sweet and good for months. This is what Jesus Christ had in mind when he said to his disciples, `ye are the salt of the earth.’ He meant that, as salt keeps meat from going bad, so good men by their goodness stop human society from getting morally rotten.
