...They? Scientists know surprisingly little about clouds, which were not even named or classified until 1803 (by an English druggist named Luke Howard). They know how clouds and fogs (clouds on the ground) are formed-by the cooling of humid air, which condenses water vapor on particles of dust, pollen or soot in the air. They also know what a cloud or fog is made of-water droplets (or ice crystals) so small that an 1,800-cu. ft. block of dense fog contains only one-seventh of a glass of water. But many questions, such as what makes...
...complain about the weeds in your garden. Eat them. There is nothing quite like a tossed weed salad, preceded by an entree of burdock stems in batter, and topped off by cattail-pollen pancakes...
...will be little if any more than an electric refrigerator. Westinghouse already has made a two-cell unit selling for $300 that will clean the air in the average six-room home." Savings on cleaning and replacements are substantial; savings on health cannot be figured although the Precipitron catches pollen and bacteria. Not even tobacco smoke, which has the finest particles found in the air (16,000 side by side are no wider than a pinhead), escapes its electrical filter...
...promiscuous sexual life of the giant ragweed (Ambrosia trifide)and other species again last week brought tears to the eyes of several million U.S. hay fever sufferers. In the next few weeks a good million tons of ragweed pollen will drift imperceptibly over the U.S. seeking mates...
Chicago could have told New York that it is wasting its time. In 1933 Chicago put 25,000 men to work cleaning up weeds (cost: $165,000). Result: no lessening in pollen concentrations, sneezes & sniffles. Reason: ragweed that grows within city limits is only an infinitesimally small source of hay fever infection. The main source is pollen carried by the wind over some 2,000,000 square miles where ragweed flourishes east of the Rockies...
