Supplement to Principles of Cookery. The Gas Stove. If gas is in common use, have members calculate the amount of gas required to bake a loaf of bread, a cake, to boil two quarts of water, etc., by observ-ing the length of time taken to burn two cubic feet - i, e., one complete revolution of the hand of the small dial D.

Water

Experiments: See pages 21, 22. Test the water boiling slowly and boiling hard with a thermometer. Note the simmering temperature and observe how much less heat is required to keep the water at this temperature than to keep it boiling vigorously. (If a gas stove is not available, use a small kerosene stove or a chafing dish burner.) A suitable thermometer may be obtained through the school for 50 cents. Loaned for 6c postage.

The experiment on page 22 can be made with one dish using the same quantity (say a cup) in each case.
