Wash and pick over a large heaping cupful of navy beans and steep them in water over night. Put them on next morning with fresh water to more than cover, and baking soda the size of a bean and let boil about an hour. Then carry them to the sink, pour all into a colander letting the water run away and put back into the saucepan with cold water enough to come up to a level. Boil again and in a few minutes they will be soft. Season with a little salt and tablespoon of molasses. Put them into four pint bowls or tin pans, lay an ounce slice of salt pork on each and bake half an hour.
