Poison Among Plants From Wisconsin Scientists
Science Service reports that several plants release soil chemicals that inhibit nearby vegetation. Prairie sunflowers, black walnuts, desert shrubs including absinthe, arid bush used for guayule rubber, woodland asters, and Indian tobacco suppress growth as they decompose in spring. Researchers John T. Curtis and Grant Cottam note these allelopathic effects.

American Past Traced by Stone Implements
Archaeology explains how North American Indians shaped arrowheads and axes from hard stones using primitive tools. A bone or ivory tool could shaping points, and crumbling with a hammer stone produced axes and celts. Banner stones with drilled holes hint ceremonial use.
Antelope Speed and Horns Highlight Western Wildlife
The pronghorn Antilocapra americana is the fastest land animal in America, capable of 45 miles per hour, with sprints near a mile per minute. Once widespread, its population rose to over 150000 under game laws. In western Texas private ranch hunts pay ranchers $40 per antelope. Pronghorn horns are hollow with bony guards, shed annually, up to 20 inches. Their fighting thrust aids mating, a notable feature of this resilient species.

Pronghorn's keen sight and white rump warn and guide
The pronghorn uses long sight to monitor distant threats like coyotes. Its white rump flags mates and signals danger, while its speed and signaling behavior once startled allow it to outrun predators. In early Western days, they raced trains, flashing white flags as they crossed engines.
