1. America's petroleum industries pour out fuel and lubricants for the United Nations. An oil well driller at a derrick operated by a large U.S. oil company signals the engineer to lower a "gun-perforater" which he is about to guide into the mouth of the well. At each of the places marked by the large visible screw-nuts on the gun-perforater is a .45 calibre cartridge. When the "gun-perforater" has been lowered to the bottom of the oil well, which has been carefully sealed with steel and cement, the cartridges will be fired simultaneously by an electric charge and the cartridge bullets will pierce holes through the well's steel casing and several inches of cement. Through these holes oil (if the well is successful) will flow slowly to the surface of the earth. This method of restraining oil flow in a new well prevents wastage which might otherwise occur if the oil is blown upwards by natural gas pressure in the oil pool. Economical methods such as these have increased the efficiency of the U.S. oil industry to a point where it can meet the tremendous demands being made upon it by the war 1944?
