Tank cars, vital link in wartime domestic oil transport; with railroads breaking all-time traffic records, they are still able to give valuable service in hauling the tank cars of the oil companies from Gulf Coast and Texas fields. But only a fraction of the required tank cars are available. Railroads are hauling 500,000 barrels daily, hope for 800,000 as more cars can be made available for movement to the East. But this still would be only half of the normal civilian requirement

Defense housing, Erie, Pennsylvania. Living conditions were so crowded in Erie, Pennsylvania, that a defense worker and his family of three were found to be living in this attic room. One of the defense industries there, which holds large contracts for the Navy, expects an increase of 4,000 workers during the coming year. Practically all vacancies are already taken, and even the contemplated construction of new homes will fill only a fraction of the need. Realizing the urgency of this need, the Division of Defense Housing has programmed 300 homes in this area, 60 of which are already completed (July 1941). In the meantime, trailers are being used by the Division as a temporary expedient until the more permanent homes are completed

When the weight of a rationed product does not come out to even pounds, the point fraction table at the bottom of the official consumer table show point values for ounces. If the odd weight comes out to a fraction of a point, a retailer can collect an extra point if it is a half point or more. But if it is less, the customer does not need to give up an additional point

Baltimore, MD. Statistical data of great value in the future will accumulate in the files of the Social Security Board Records Office. To provide easy means of developing and studying this information, without disturbing the permanent records, acturial cards are reproduced from the original employee master cards. The master card is a [...] salmon pink. The acturial card is a bright green. They are of different colors so they will not be mixed together inadvertently. The photograph above shows a reproducing machine making acturial cards from master cards. The punched master card is placed in one compartment. A blank acturial card is placed in another. When the master card has been automatically carried to the proper position it stops, momentarilly. Meanwhile the blank acturial card is carried to another place in the machine. Electrical impulses cause the machine to punch on the acturial card the same holes, in the same position, as on the master card. The two cards are held in place while the part of the machine holding the acturial card telegraphs back to the part holding the master card to see that the punches in each are identical. Then the cards are released, one is in one pile and the other in another. The whole operation requires a small fraction of a minute

Tying in new spools. This is a highly skilled occupation, and is supervised at this tire company by a man whose previous training was in a weaving mill in Scotland. The deft weaver's knot, which will not pull out, must be tied in the fraction of a second whenever a break occurs, to catch the broken ends together without interrupting the flow of cord. Firestone (General Tires), Akron, Ohio
