Passage Two

Never laugh at a snow covered mountain! Laughter and yelling, during the avalanche season, can cause a deadly pile of snow. Huge snow slides are most common in mountains where there are steep slopes that are well buried in snow and ice. The snow builds up slowly and lands very softly. This can create a very touchy, unstable situation. Tons of snow may be held up by only the friction between snowflakes. The deep snow is like a house of cards. The slightest movement can cause it to fall . As soon as something slips, this great mass of snow will come crashing down the mountainside.
Slides may be started by sound vibrations. They may also be started by the weight of wet, melting snow. Once an avalanche has been triggered, the cause no longer matters. Moving down a steep slope, it picks up great speed and added snow. Some avalanches travel as fast as two hundred miles per hour. The force of an avalanche will mow down anything in its path. Whole houses have been swallowed up by these fast-paced piles of snow.
The wind that is caused by an avalanche is almost as destructive as the snow itself. Winds from an avalanche have been known to travel as fast as those of a tornado. So, when approaching a thickly snow covered mountain, speak softly!

Passage Three

What could be simpler than shaking fruit from a tree? Well , the job is a lot tougher than you might think. There is definitely a right way and wrong way to shake a fruit tree. And a person who is a good apple tree shaker may not be a good cherry tree shaker. Different fruits take different shakes.
As a rule, a slow hard shake is best. This makes the fruit fall much faster than a light, quick jiggle. Most fruits have a set  number of shakes per minute that will do the best job of getting them out of the tree and onto the ground. To shake down plums, try shaking the tree four hundred times per minute, moving the tree two inches at each shake. Experts say you’ll get three times more fruit from the tree than you will if you shake eleven hundred times per minute at one inch per shake. Cherries, because they are smaller, need more jarring. A good rate of shaking seems to be about twelve hundred shakes per minute . Apples, like plums, need four hundred shakes.
Of course, some folks may be choose to ignore all these expert directions for jiggling fruit. Keeping track of all the numbers can be enough to drive some people up a tree.
