...prepared for them a bowl of the sacred nectar kava, "by drinking which the Chief is brought near and like unto his people." When this potent beverage had been mixed, stirred, and the more solid ingredients pounded in a great bowl, the Chief personally strained it through a filter of woven bark, saying: "This make kava very nice. This take out all the grit." The Duke, no weakling, downed a huge swallow of kava. Thereafter, although flushed for a moment, he gave no sign or indication of its taste...
...hard time finding a place to take it; he goes into a hotel washroom, a taxicab, even a telephone booth. Out of his pocket comes a piece of candle. He wants to sterilize his injection. He puts water in a spoon, heats it over the candle, dissolves his morphin, filters the solution through cotton, fills his needle, injects. It is to him a holy ritual.

From Berlin came reports of a new photochemical process for producing naturally colored cinema films at no greater expense or effort than black and white effects require. An ordinary camera was used and an ordinary monochromatic film, treated specially but simply. No "screen" or "color filter"* was needed on camera or projector. Fringes of color-bane of films made with filters by superimposing sets of negatives-were unknown. The only features of the invention described by correspondents were: 1) that the film had to be run twice as fast as a black and white film (i.e. 32 instead...
...Thus, pictures in newspapers are made with screens having 60 lines to the inch; pictures on paper with an ivory-like finish have been made with screens up to 400 lines to the inch. Color Process. Europeans had solved the problem theoretically when Ives first made practical "color filters" for a camera, to extract from a colored painting the patterns and values of the three primary colors composing it. As every one knows, each primary color-yellow, blue, red-has its complementary- violet, orange, green. When added to its complementary, each primary color becomes black. Thus, to obtain a negative...
