1/2 tsp. salt
1 c. butter, piled softly

Sift flour, cream of tartar, baking soda and salt. Cream butter and vanilla until butter is softened. Add 1 cup sugar gradually, creaming until fluffy. Add beaten eggs in thirds, beating after each addition. Add dry ingredients in fourths to cream mixture. Chill dough 1 hour at least. Grease cookie sheets.
