America's petroleum industries pour out fuel and lubricants for the United Nations. An "oil flow chart," showing the course of oil through a modern plant, is being studied by men of an oil "cracking" unit in the U.S., while an expert explains to them the intracacies of the chart. Large oil "cracking" plants, for the rapid production of aviation gasoline and other products, are one of the most recent developments in the refining phase of the oil industry in the United States. Crude oil in these units, when subjected to great heat and pressure, is forced to give up more of its derivable elements than by former methods of refining. The process "cracks" or breaks down the crude oil molecules. In the last eight years since the process was put into operation more than 1,000,000,000 barrels of crude oil, it is estimated, have been saved by the large quantities of crude oil products now being made available to the combat units of the U.S. and her allies
