Actually cob and adobe are somewhat different.  Traditionally, adobe has
little or no organic fiber (up to ~3%) and was hand packed into walls as
puddled adobe.  The Spaniards introduced the idea of the brick which was
then widely adopted by the SW Indians.  The bricks were dry laid or
mortared with a mud mortar.  The adobe 'ingredients' are clay or caliche as
the binder, gravel or sand, and sometimes fiber which could be straw, pine
needles, grasses, horse hair or other organic fiber.  Adobe can be mixed
easily in a mixer then poured into brick forms and left to dry in the sun.
