In a medium mixing bowl cream the butter and sugar. Add in maple syrup and mix well.
In a small bowl combine the flour and baking soda. Gradually add to the creamed mixture and mix well.
Divide dough into 8 equal portions. Roll each portion into a 9" log. Place on an ungreased baking sheet 3" apart. Bake for 20-25 minutes or just until lightly browned on edges.
Cut into 1" slices and remove to wire racks to cool completely.
