First, look over the beans and release any dark or shriveled beans, and add to a heavy bottomed pot (I used an enamel cast iron).
Next, add the bay leaves, carrot, celery, salt, oil, and enough water to cover by about 2 inches.
Then, bring to a boil. Skim off any white foamy residue. Cover leaving the lid slightly ajar, and cook on medium (Simmer) for about 1 hour.
Lastly, check the level of the water often, and add some boiling water if they get too dry.
