Snow written by Marion Dane Bauer illustrated by John Wallace
The winter world is cold.
The trees are bare. The grass is brown.
Gray clouds crawl across the sky.
Clouds are crystals of ice. Each bit of ice clings to a speck of dust.
The specks of ice and dust cling to one another. They grow so heavy that they drop from the cloud.
