Fill the bowl of the lamp with a good grade of oil, not too full, because as the oil warms it will expand and may over- flow. This is not dangerous, of course, any more than it is dis- agreeable to have oil spilled on things. It may cause smoke, or the oil may find its way to the eggs by means of the operator's hands, which will endanger the hatch.

For this reason it is a good plan to turn and handle the eggs before caring for the lamp. Regulating Flame. — If the machine is of the hot-water type, then, of course, the tank must be filled with water before the lamp is lighted. After lighting the lamp and placing it firmly in position, which should be accom- plished without jolting the ma- chine, regulate the burner so that the flame is about half as high as it should be finally. The reason for this is, as soon a^the chimney or heater warms, it will draw the flame upward and increase its height. It is, therefore, a safe practice to return about a half- hour after the lamp is lighted, to see that the flame is all right. Skilled operators visit their in- cubators at frequent intervals, including an inspection the last thing at night. The machines seldom need attention, but it is gratifying to assure oneself that everything is running properly. In hot weather, when the temperature of the cellar is likely to rise in the middle of the day, especially toward the close of a hatch, when the eggs themselves radiate considerable heat, it is often necessary to lower the burner of an oil-burning machine almost to the point of extinguishing it. In some cases I have found it. (Courtesy Buckeye Incubator Company) Fig. 156. — Well-built incubator heater protected by metal casing.
