Beat butter, sugar and 1 tsp. Peel till well blended. Add eggs, 1 at a time, stirring well after each addition. Stir in vanilla. Mix flour and baking powder together. Add nuts. Divide dough in half. On lightly floured board, shape each portion into a roll about 1 1/2" in diameter. Place rolls on greased baking sheets at least 3" apart. Flatten rolls to make 1/2" thick loaves. Bake at 350 for 15 min. Remove from over and cut crosswise into 1/2" slices. Lay cut side down on baking sheet. Bake till browned, about 20 min. Cool. Spread icing on tips of each cookie.

Icing: Mix sifted powdered sugar, 1/2 tsp. Lemon peel and 1 to 1 1/2 tsp. Lemon juice-enough to make icing easy to spread.
