In the 1920’s, but especially in the Depression conditions of the 1930’s, the United States experienced a declining...
Clear Your Mental Space Think about the last time you felt a negative emotion—like stress, anger, or frustration. What was going through your mind as you were going through that negativity? Was your mind cluttered with thoughts? Or was it paralyzed, unable to think? The next time you find yourself in the middle of a very stressful time, or you feel angry or frustrated,...

初雪 初雪飘临。多么美啊！它整日整夜那么静静地飘着，落在山岭上，落在草地上，落在世人的屋顶上，落在死才的坟墓上！在一片白茫茫之中，只有河流在美丽的画面上划出一道曲曲弯弯的黑线；还有那叶儿落净的树木，映衬着铅灰色的天空，此刻更显得枝丫交错，姿态万千。初雪飘落时，是何等的宁谧，何等的幽静！一切声响都趋沉寂，一切噪音都化作柔和的音乐。再也听不见马蹄得得，再也听不见车轮辚辚！唯有雪橇...

Paid for and maintained by “light dues” levied on ships, the original beacon was blown up in 1776. By then there were only a...

Vision Human vision like that of other primates has evolved in an arboreal environment.In the dense complex world of a tropical forest, it is more important to see well than to develop an acute sense of smell. In the course of evolution members of the primate line have acquired large eyes while the snout has shrunk to give the eye an unimpeded view. Of mammals only humans an...
Plants in the Deserts Some cacti, like the saguaro, grow to tree size, but true trees need more moisture than most desert environments can supply, so they are scarce on deserts. Close to streambeds, cottonwoods can sometimes be found. Though these streams are dry most of the year, water flows there longest and is usually available fairly close to the surface. Elsewhere, tree...
Piano The ancestry of the piano can be traced to the early keyboard instruments of the fifteenth and sixteenth centuries — the spinet, the dulcimer, and the virginal. In the seventeenth century the organ, the clavichord, and the harpsichord became the chief instruments of the keyboard group, a supremacy they maintained until the piano supplanted them at the end of the ...

Some fears are valid, like walking alone in a bad part of town at two o’clock in the morning. But once you learn to avoid that situation, you won’t need to ...

For I have sworn before you and Almighty God the same solemn oath our forebears prescribed nearly a century and three quarters ago. In your hands, my fellow citizens, more than in mine, will rest th...
Obtaining Fresh Water from Icebergs The concept of obtaining fresh water from icebergs that are towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life.
