Magnetic Mapping Promises Oil and Iron for Future Use
Magnetic surveys using airborne magnetometers offer rapid mapping of crustal structures to locate iron ore deposits and petroleum areas. The new technique, developed during World War II to detect submarines, enables large areas to be surveyed from air or land, with Alaska and Gulf regions cited. It aims to produce nationwide magnetic charts, aiding oil exploration and mineral discovery despite not directly detecting oil.

Intermittent Syphon Demonstration For Junior Scientists
A 1946 Science Service piece explains Tantalus cup and intermittent siphon concepts. It details building models with glass tubing or rubber hose, a funnel, and a cork stopper, plus a beach or lot setup to demonstrate periodic flow and siphon break. It notes careful bending, heating, and slow water flow to mirror the natural siphon.
Hedge of Many-Flowered Rose as Livestock Fence

Blind gardeners grow with special tools and wire guides
Armand Michaud, the first blind gardener to use these devices, demonstrates tools that let blind people prepare soil, plant in straight rows, and weed. Hugh Findlay, former Columbia landscape director, devised the gadgets used by war blind in 28 states and abroad.
