Every householder and housekeeper should have more definite knowledge regarding the amount of heat available from a given bulk of each of the stand ard fuels. One cord of wood is approximately equal to one-half ton of coal; 1,000 cubic feet of coal-gas is equal to 50 or 60 pounds of coal, or about four and one-half gallons of oil or gasoline. The time required to keep stove and fire in good condition must be counted with the cost of the fuel.

In this connection, facts reported in some of the test papers received are interesting.

From a southern plantation, wood is reported as costing only the labor of preparation for the stove, and that only sixty cents a cord. In another locality, one sixteenth of a cord of wood is used daily at a cost of twelve cents, or about two dollars a cord. Elsewhere, a housekeeper finds wood at five dollars a cord the cheapest fuel within her reach, and estimates her daily supply to cost ten cents, or about one fiftieth of a cord. Another burns a cord of wood each week for cooking only.

An English pupil writes: "The range to which I am most accustomed is the almost universal farmhouse open fireplace and Glendenning oven, used in Cumberland and Westmoreland. The oven is heated by the hot air from the fire by a passage at the back of the fireplace, with only one damper for oven. At the opposite side there is nearly always what is called here a 'set-pot' for heating water. The heat of my oven is greatest at the bottom, on account of the hot air being underneath. What is not cooked in the oven is done over the open fire."
