the grate depends on the draft required. Shaking the fire after light appears irD the-ash pit may waste fuel by permitting partly burned fuel to drop from the firepot. A deep fire bed allows the absorption of the greatest amount of heat by the heating chamber and prevents the formation of "dead spots" which cool the fire. The top of the fire bed should be kept even with the firing door in cold weather. A size of coal which will not readily fail through the grate should be selected. Screened coal of the large sizes is most satisfactory where difficulty is encountered in obtaining sufficient draft. Opening a window in the base- ment may increase the draft at times. SOFT COAL CAN BE ECONOMICALLY USED IN AN ORDINARY FURNACE As soft coal is heated large quantities of combustible gases are released. Proper conditions must be maintained in the heater for the combustion of these gases or they are lost as smoke and represent, a considerable fuel loss. To secure the maximum amount of heat, soft coal must be fired frequently. Before adding a charge of green coal push part of the live coal back to make room for the new charge. Do not cover more than half of the grate with green coal Leave the draft door at the ash pit and the draft slide in the firing door open. The latter adjustment allows air to enter at the top of the fire bed. The air mixes with the gases and the mixture burns as it comes in contact with the flames from the live coal.

If both bard and soft coal are used in the same heater, best results can be obtained by firing with soft coal during the day and banking the fire with hard coal at night. WOOD 18 THE CHEAPEST FUEL TO USE ON MANY FARMS Farmers who have a woodlot can effect a big saving by using wood in place of coal. Wood can be cut during the winter when there is little fetm work to do. Wood can be burned successfully in an ordinary furnace. Its use requires more frequent firing than with coal, but a wood fire wiln heat a house more rapidly. It may be found difficult to "hold fire" for Any length of time unless all joints and doors of the heater fit practically airtight. Banking with ashes will reduce the draft and "hold the fire" for a longer period. Wood burn- ing furnaces can be purchased which will burn wood of cord lengths. These heaters are designed to burn wood at a much slower rate than the ordinary furnace and therefore less frequent firing is required. GET READY TO SAVE FUEL THIS WINTER Save coal this coming season by putting your heating system in first class condition before autumn. Substitute wood for coal if practical.
