...conceived the idea of making motor fuel from coal by hydrogenation under high heat and heavy pressure. Over the following two decades he and other chemists in Germany, Britain and Canada converted the idea into an industrial fact. Finely powdered coal is made into a paste by mixing with tar or a tar derivative, the mixture fed into a heavy steel cylinder. At 840° F, hydrogen gas is brought in under 3,700 Ib. per sq. in. pressure. The hydrogen combines with the carbon or carbon compounds in the coal...
Chronic irritation always seems to be the immediate cause of cancer whether the victim is genetically vulnerable or not. The irritation may be mechanical (ill-fitting dentures), physical (pipe smokers' lips), chemical (tar roofers' hands), digestive (caused by bile acids), endocrine (caused by sex hormones). Said Dr. James Bumgardner Murphy of Manhattan...
...there is a plethora of fish and small game. And don't you believe there isn't ample time to garden, hunt and fish! I have myself lived in a house scarcely better-built than the shack pictured in TIME. It was a four-room box, tar-paper-roofed, and you could throw a cat through the cracks in the walls. We whitewashed it, papered it ourselves, and by the time my mother, a very frail woman, had planted simple flowers, the wretched place looked rather charming. Except for actual ploughing, we raised a garden and fed ourselves...
...biographers bring in antipodal reports on their huge subject. Following William Randolph Hearst from his abbreviated career at Harvard, through his early publishing ventures in California, his entry into New York, his pre-War triumphs and present stormy twilight. Authors Lundberg, Carlson & Bates liberally plaster Publisher Hearst with controversial tar, while Mrs. Older is equally generous in coating her hero with sympathetic whitewash. Some contrasting findings on the character & career of Mr. Hearst...
Naval stores originally got their name because as long as ships were wooden, pine tar and pitch were chiefly used in calking hulls and in tarring rope. The first Englishmen who went to North Carolina in the 16th Century saw in the Southern pine forests supplies of pitch and lumber which would make English shipbuilders independent of Scandinavia for these necessities. The same timberlands 300 years later were yielding two-thirds of the world's turpentine and rosin, the simplest derivatives of pitch. By 1900 there were 1,500 distilling centres in the South with an annual production...
