This important principle is often overlooked while con- sidering points appar- ently more practical. The Indians of Peru are said to have used for centuries, in pro- tecting their crops from "gravity " spring frosts, a heavy clay pot in which char- coal is burned. By this means they se- cured radiated heat almost exclusively. From a considera- tion of the above re- quirements it will be seen that the develop- ment of a thoroughly practical and efficient oil heater is not an easy matter. Four or five of the require- ments may be combined without much difficulty, but some are more or less conflicting. It is especially diffi- cult to combine perfect combustion and control of combustion with simplicity and Fig. 84. — Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Coit, J.
