Butter Crackers.

Rub the butter into the flour, or, what is better, cut it up with a knife or chopper, as you do in pastry; add the salt, milk, and soda, mixing well. Work into a ball, lay upon a floured board, and beat with a rolling-pin half an hour, turning and shifting the mass often. Roll into an even sheet, a quarter of an inch thick, or less, prick deeply with a fork, and bake hard in a moderate oven. Hang them up in a muslin bag in the kitchen for two days to dry.
