With each passing day it becomes colder. The sun is shining, but not warm. The day the earth does not have time to heat up. The days grow shorter and the nights longer. Gets dark early.        The leaves on the trees turn yellow and fall off. All the land is strewn with fallen leaves. Thinning treetops. Can not hear the birds singing. Dried grass. Withered flowers.        The sky is often covered with dark clouds. Go cold slanting rain. Gusty, biting wind. Harvested in orchards and gardens. In the fields empty. Only here and there are green shoots oziminy. Everything reminds that autumn came.
