—Rub together half a teaspoonful each of salt and cream of tartar with nearly a teaspoonful of bicarbonate of soda and 1lb. of flour; make this all to a soft, lithe dough with buttermilk, knead it for a little on a floured pastry board, roll it out about ğin. thick, shape it into round cakes (a clean saucepan lid is a capital cutter), cut each across into four, and bake on a not too hot floured girdle.
