Wash the beans and put them on to cook in boiling salted water, to each
quart of which one-eighth of a teaspoonful of soda has been added. If
the quantity is small, put them into a small pail set into a larger pail
of water. If the whole will fill a two-quart cooker-pail it will cook
without the larger pail. Put them into a cooker for one and one-half
hours or more.
