Have ready a quart of boiling water in a farina-boiler, or use a small pail set in a saucepan of boiling water. If oatmeal or any grain is boiled in a single saucepan, it forms, no matter how often it is stirred, a thick crust on the bottom; and, as "never to stir" is a cardinal rule for all these preparations, let the next one be, a double boiler.
Add a teaspoonful of salt to the quart of water in the inside boiler. Be sure it is boiling, and then throw in one even cup of oatmeal or crushed wheat. Now let it alone for two hours, only being sure that the water in the outside saucepan does not dry away, but boils steadily. When done, each grain should be distinct, yet jelly-like. Stirring makes a mere mush, neither very attractive nor palatable. If there is not time for this long boiling in the morning, let it be done the afternoon before. Do not turn out the oatmeal, but fill the outer boiler next morning, and let it boil half an hour, or till heated through.
