"We might do well to stay home a few days and walk over the fields, or to stand in the shelter of the barn door and reflect upon the relentless and yet benevolent forces of Mother Nature. The laws of nature are relentless. They can never be disobeyed without exacting a penalty. Yet they are benevolent, for when they are understood and obeyed, nature yields up the abundance that blesses those who understand and obey."
