Studying why fruits taste that way. E.K. Nelson of the Department of Agriculture is shown making tests with an apparatus which the Department imported from Germany for the purpose of studying the essential oils or "flavor-giving" content of fruits and vegetables. At present chemists are acquainted with the essential oils of only a few fruits, such as some of the citrus group. The apparatus is a vacuum distill which permits the distillation of liquids at temperatures much lower than usual by reducing the pressure, 1/10/31

Health measures for low home temperatures. With less fuel available to heat America's homes, youngsters must have the right kind of inner fuel to keep them warm and healthy in sixty-five degree rooms. A balanced, vitamin-rich diet will aid materially in enabling children to build up resistance to the colder temperatures which will prevail this winter in homes and schools

Conservation. Glass gauges replacing steel. Mr. A.E. Smith and Mr. Stanley Farrow (left to right) of Army Ordnance's Gage Section, discuss glass gauges, which replace steel gauges at the Frankford Arsenal. Glass gauges are lighter and cheaper than steel, permit greater visibility in inspection, are not as much affected by room temperatures and heat of operators' hands, are not corroded by perspiration, need no protection against rusting, do not acquire burrs that would change the effective sizes. They can save the annual use of 250 tons of critical tool steel in Government arsenals alone

Chicago, Illinois. Subsistence research laboratory of the U.S. Army quartermaster depot. K ration is highly concentrated, and is used only in time of emergency and continuous combat when regular messing facilities are not available. Packed in three boxes for three meals, it weighs only 32.86 oz. and contains 3,726 calories. It is so packed that it will not be affected by temperatures up to 135-F or down to 20 below zero

Hams now aged in 6 to 10 weeks. College Park, Md. Oct. 27. No longer is it necessary to age ham a year or so to obtain that sharp, pungent, cheesy flavor in the lean meat, so characteristic of southern style ham. Speeding up nature, the Maryland Experiment Station, University of Maryland, in cooperation with the U.S. Department of Agriculture, has developed a process by which it is possible to produce some of these characterisitc flavors in hams in relatively short time--6 to 10 weeks--by holding them at temperatures from 107 F to 125 F in specially constructed incubator. 1. The first step in the process is the thorough curing of the hams, three days being allowed for each pound of ham being cured. Mr. F.D. Carroll, of the Maryland Experiment Station, is shown with a few of the hams after they have been cured

Fuel conservation. Home insulation conserves fuel. Every homeowner can get behind his government's efforts to conserve fuel whether he heats his home with oil or coal, and both are strategically important. Fuel savings can be effected by keeping temperatures at reasonable levels, closing off unused rooms, and insulating in various ways. Windows can be weather stripped. Conservation of fuel will help release railroad and other transportation facilities for the movement of fighting materials

Health measures for low home temperatures. The American male, accustomed to heavy clothing indoors and out, probably won't mind the lower home temperatures imposed by the government's fuel oil limitation order; but the ladies had better adopt costumes of warmer materials made with long sleeves to ward off the chill air this winter

Conservation. Glass gauges replacing steel. Checking the inside diameter of a cartridge case with one of the glass gauges, which are replacing steel gauges at the Frankford Arsenal. Glass gauges are lighter and cheaper than steel, permit greater visibility in inspection, are not as much affected by room temperatures and heat of operators' hands, are not corroded by perspiration, need no protection against rusting, do not acquire burrs that would change the effective sizes. They can save the annual use of 250 tons of critical tool steel in government arsenals alone

Conservation. Glass gauges replacing steel. A plain plug glass gauge, which replaces a steel gauge in the Frankford Arsenal, is used to determine the inside diameter of a metal part.
