Mix and sift together rye, graham flour, corn-meal and salt. Dissolve soda in molasses. Add alternately to flour with sour milk. Grease one-pound baking-powder cans, put in the dough and boil two and one-half hours, keeping the water always three-fourths up around the tins. Turn out on baking-tins and place in the oven fifteen minutes to brown.
To be eaten warm, whatever is left over can be steamed again or toasted.
