Mr. Brown, Martin and Sylvia's next door neighbor, loves everything that grows on his farm.  He loves every blade of grass, every tomato plant and every tall tree.  He particularly loves an old maple tree he called Sweetness.  "I've know this tree all my life," he told Martin one day, "And though she might not be the prettiest tree in the lot - they all know who is in charge."  When the farm is surprised by a sudden ice storm, Mr. Brown is faced with a difficult decision about his favorite tree - and the children know just how to help.
