...George Harrison Shull, professor of botany and genetics at Princeton University, gave hybrid corn to the world free of charge. But the U. S. Department of Agriculture pointed out last week-just for fun-that if old Dr. Shull had received a royalty of only 1? an acre for the 25,000,000 U. S. acres planted to hybrid corn in 1939, he would have taken in $250,000-a tidy income for a scientist. In 1939 Iowa planted 77% of her total corn acreage to hybrid corn, Indiana planted 60%, Illinois and Ohio 57% each...
...Hybrid corn is the result of inbreeding various strains for several generations, then crossbreeding. Corn, like mice, mackerel and men, reproduces by means of male sperm and female eggs. The sperm is produced and dispersed from the tassels at the top of the stalk; the eggs lurk at the base of the silk on each ear. In ordinary "open-pollinated" corn, fertilization occurs at random, the sperm-bearing pollen being carried to the silk by the wind. For inbreeding, the tassels and silk are protected by paper bags until maturity, and the plants are then self-pollinated by hand. These...
...Hybrid seed costs about twice as much as ordinary cornseed, but yields increases of 10% to 40% per acre-increases so huge in farm eyes that one group of farm publications declared: "Hybrid corn is the most spectacular and far-reaching agricultural development of this generation. It ranks in importance with the invention of the telephone and the internal combustion engine. ... In the midst of economic transition, most people have overlooked the transition in food production technique, of which hybrid corn is the forerunner...
...finally brought to Bounty Bay by the crew of a Tahitian tramp. That was before a best-selling trilogy and a four-star movie made Pitcairn Island the most publicized hideout on the seven seas, and prompted a well-meaning, sympathetic U. S. to enrich the 200-odd hybrid islanders with all sorts of civilized niceties, including a powerful amateur short-wave radio station, VR6AY...
William Thomson, associate professor at Harvard since 1929, was promoted to the post of James Richard Jewett Professor of Arabic. In the new hybrid field of Geology and Geography, Russell Gibson, former assistant professor of Economic Geology, was made an associate professor. From the position of assistant professor of Palaeontology, Frank M. Carpenter '26 has been promoted to associate professor of Entomology in the Museum of Comparative Zoology...
