Foresters are people who work with trees and know a lot about them. Occasionally, foresters have problems, and the foresters in southern Indiana have had many problems.

The foresters were doing an experiment. They wanted to grow walnut (胡桃) trees by planting walnuts in the ground. If they succeeded, the foresters would be able to control the location of the trees. Also, this method would be much cheaper than transplanting or moving nut trees that were grown in plant nurseries (苗圃) . So the foresters planted their walnuts, and that’s when the squirrels (松鼠) started causing trouble. Shortly after the nuts were planted, the squirrels dug them up for tasty snacks (快餐) .

The foresters tried to keep the squirrels away from the walnuts. Mothballs (卫生球) were used as a warning, but they didn’t work. Then, the foresters tried dipping the walnuts in kerosene (煤油) ,  but that didn’t stop the squirrels either. The foresters continue to search for a method that will really work. But until they find one, the squirrels can continue to have their walnut snacks and the foresters will have to transplant trees!
