BRINE-PIT, in salt-making, the salt spring from whence the water to be boiled into salt is taken. There are of these springs in many places; that at Nantwich in Cheshire, is alone sufficient, according to the account of the people of the place, to yield salt for the whole kingdom; but it is under the government of certain lords and regulators, who, that the market may not be overstocked, will not suffer more than a certain quantity of the salt to be made yearly.
