...Johannesburg, South Africa, a Scotch goldminer saved the sediment of his baths for 20 years. When he panned the accumulation from 20 years' baths, he had 20 ounces of pure gold, worth almost...
Because of that ever present hazard, fuel is ordinarily strained into an airplane's tanks through chamois or billiard-table felt, which are impervious to water. The process is slow and not without danger of fire, as the strainer easily becomes clogged with sediment and the funnel full of gasoline is constantly exposed to static electricity. Last week it. was disclosed that the Army Air Corps had adopted a filtering device with neither of these bad features, invented by Master Sergeant David Samiran, stationed at Wright Field, Ohio. The invention, known as a segregator, is based on the difference...
...shabby, smalltime sporting-club in Brooklyn, 2,000 representatives of the fertile social sediment in which prizefighting has its roots last week watched a preliminary bout between two light heavyweights. One was a shaky, timid Negro, the other a slow-footed, lumbering white man with a scarred face and a flat nose.

Like most cheap preliminaries, it was mediocre entertainment and the crowd booed. Unlike most cheap preliminaries, it was described at length in metropolitan...
Determining Sediment...
Quite often the tube must be dropped 2,000 to 3,000 fathoms in order to reach the bottom. Because of the slow accumulation of sediment in midocean this tiny core of mud may represent thousands or even hundreds of thousands of years. Scientific interest lies in measuring the thickness of these stratifications of mud cores in order to determine former changes in depth and climate. Telegraph companies are particularly interested in this work, because they wish to learn how fast matter accumulates on the sea bottom in order to avoid laying cables in regions where the rate of deposition...
