Cream butter and 1/4 cup confectioners' sugar.
Add remaining ingredients and mix well.
Shape into rolls about 1/2 inch in diameter and cut into 1-inch pieces.
Put on ungreased cookie sheets and pull ends down slightly to form crescent shapes.
Bake in preheated moderate oven (375°F.) for about 15 minutes.
While warm, roll in confectioners' sugar; roll again when cool.
