A Young Man’s Promise
One day, a young man was writing a letter to his girlfriend who lived just a few miles away in a nearby town. He was telling her how much he loved her and how wonderful he thought she was. The more he wrote the more poetic he became. Finally he said that in order to be with her, he would suffer the greatest difficulties, he would face the greatest dangers that anyone couldn’t imagine. In fact, to spend only one minute with her, he would swim across the widest river, he would enter the deepest forest, and he would fight against the fiercest animals with his bare hands.
He finished the letter, signed his name and then suddenly remembered that he had forgotten to mention something quite important. So, in a postscript below his name, he added:
“By the way, I’ll be over to see you on Wednesday night, if it doesn’t rain.”

Soils
There are many different kinds of soils. Different soils have different types of rock and minerals in them. Some soils have more water in them than others. Some soils might have more plant and animal material in them, too.
Different kinds of soils are found in different parts of the world. There are several kinds of soils found in the United States. In some areas, the soil has a lot of clay. Other soils are very sandy. Loam is a kind of soil that has a good mixture of clay and sand.
In some places, soil layers are very thick. Lots of plants grow in places with a thick soil layer. In dry and windy places soil layers are much thinner. Layers of soil on mountains are thin because gravity pulls the soil downhill.
The type of soil in a particular place affects what kinds of plants can grow there.
