The Sap Season.

The sap season throughout the maple sugar belt of the United States generally begins about the middle of March and continues until the third week in April but it varies very widely with a late or an early spring. Sugar making has begun as early as February 22 and as late as the first week in April. The season lasts on an average about four weeks. The longest run on record included forty-three days, and the shortest eight days.
