Milk Frosting

1½ cups sugar

½ cup milk

1 teaspoon butter

½ teaspoon vanilla

Put butter in saucepan; when melted, add sugar and milk. Stir, to be sure that sugar does not adhere to saucepan, heat to boiling-point, and boil without stirring thirteen minutes. Remove from fire, and beat until of right consistency to spread; then add flavoring and pour over cake, spreading evenly with back of spoon. Crease as soon as firm.
