Early Southerners ate a rather limited and unvarying diet. At table the famished guest seldom found more than bacon, corn pone, and coffee sweetened with molasses. Pioneering sociologist Harriet Martineau complained that “little else than pork, under all manner of disguises” sustained her during her visit to the American SouthFor the most part, slaves observed the same diet as poor white farmers. Though many kept gardens, and thus supplemented their rations of pork and corn with a wide variety of vegetables, they had otherwise little opportunity to augment their diet.. Another traveler griped that that he had “never fallen in with any cooking so villainous.” A steady assault of “rusty salt pork, boiled or fried … and musty corn meal dodgers” brought his stomach to surrender. Rarely did “a vegetable of any description” make it on his plate, and “no milk, butter, eggs, or the semblance of a condiment” did he once see.
Math Is No Match for Locust Swarms. "Mathematicians have now figured out the dynamics that drive locusts across the landscape, devastating everything underfoot — and the math says people will never be able to predict where the little buggers will go.
The new analysis, reported in an upcoming issue of Physical Review E, suggests that random factors accumulate and influence how swarming locusts collectively decide to change course.
“These swarms are driven by intrinsic dynamics,” says team member Iain Couzin, a biologist at Princeton University. “In all practical terms, predicting when a swarm is going to change direction is going to be impossible." More information here.

Tracking African locust swarms - a rainy winter and spring in northwestern Africa promised a rich harvest for area farmers, but instead has brought plagues of ravaging locusts... "Swarms of locusts can contain as many as 80 million locusts per square kilometer...a small part of a typical swarm can eat as much food as 2,500 people in a single day."
