...reach into the soil and draw mineral-laden water to the surface. When the water evaporates through the leaves, the minerals it carried remain in the plant's tissues, eventually falling to the ground and becoming part of the humus on the surface. Geophysicists analyze this "biologically enriched" layer and the leaves of growing plants. Finnish geochemists found a rich copper-nickel deposit by examining the ashes of birch leaves...
Hole in the Sky. A comparatively new problem is the effect of the moon's shadow on the ionized layers in the earth's upper atmosphere. These layers have a profound influence on radio transmission: they bounce some radio waves back and allow others to pass through. Since the ionized layers are caused by ultraviolet light from the sun, they presumably change their character when the moon's shadow knocks a hole in the sun's radiation. Long before the eclipse, begins, the scientists will have radar-like radios of various wavelengths trained upon each layer...
...projected program of National Selected Morticians Inc. for the burial of highly radioactive bodies by lowering the caskets into excavations floored by a copious layer of concrete and then completely surrounding them with more concrete poured to fill the excavations [TiME, March 17], is totally unnecessary...
Since January, blizzard after blizzard had struck Eire, until three-quarters of the land was covered with a two-foot layer of granite-hard ice. There is a tradition that on March 17 Saint Patrick turns "the stone warm side up" to make the soft, drying west wind blow over Ireland. Two days before the Saint's day, a thaw came, but with it a ten-hour fall of rain and sleet. Ireland's rivers boiled in swollen anger, flooding the lush valleys in Meath, Carlow, Athlone, Cork and Wexford. In Kilkenny town the floods were the worst...
