Article discusses research on profound sleepiness and eye behavior. Professor Walter Miles explains how eyelid closure may start sleep and how open eyes can still indicate wakefulness. It covers methods using eye movement cameras and two devices, with a case of a typist in night experiments.
Mercury vapor engines promise high efficiency by recirculating heated mercury to produce electricity. Early tests in Hartford show a 13,000 horsepower output with a closed cycle using a mercury condenser and heat recovery. Inventor William Emmet and Hartford Electric Light Co. led the development, with mercury costing up to 200 dollars per gallon and strict welded joints to prevent leaks.
A 1929 feature explains methods studios use to censor talking pictures. Operators may mute sound during screenings, but a better system uses a small detection unit with headphones and a lens to pinpoint sections to edit. Directors mark the film for removal, and vocal passages are painted over on the sound track.
The article outlines several inventions by American inventors. Arthur G. Norsworthy of Jacksonville Florida patents a horizontal net ironing-board attachment framed by galvanized iron piping with arms to grip the board’s standard. Forbes W. Guy of Concord California designs an ash receiver that extinguishes a lit cigar or cigarette by water, attachable to tables or cars, using a wire-net basket and a water cylinder with a piston. Oscar A. Hug of Brooklyn introduces a tiny electric lamp for fountain pens, using a spring ring, a curved plate, and a rocket feature with a parabolic reflector for illumination.
A newspaper note explains that cereals such as wheat corn and oats contain vitamin D but in limited amounts. Exposing prepared cereals to ultraviolet rays before packaging boosts vitamin D content, a process now used by cereal manufacturers after steaming and sterilizing the milled grain.

The oyster mushroom grows on dead wood and in damp logs, especially on hickory and other hardwoods. It appears after hot damp nights, often covering roots to twenty feet high, with a delicate shell like form.
Scientists report a mysterious yolk substance dubbed grow stuff that accelerates growth in eggs seeds and larvae. Experiments by Dr Danilewsky and Dr Koch show phosphorous compounds in yolk boosting skeletal growth and overall weight in baby animals, with potential synthetic production on the horizon.
