First you get together a big pile of dirt and wet
 it down

Then, you add in the lighter colored clay dirt
and mix it up in the pile with the water.

Then, you get some straw and put it in the pile,
and someone has to stomp on it and shovel to
 mix it all up. The straw helps hold the adobe together.

Meanwhile, the wood mold or form is kept in water so the adobe won't stick to it, ie build up and deform the bricks.

So they shovel the wet adobe into the form, and the consistency is such that immediately the form can be taken off.  Note that 2 bricks are made with the form, and as they dry they get very light colored. After the bricks are dry enough to move, about a day, they are first turned over to dry more evenly, then put on end to keep drying and to make more space in the yard for the new bricks. Then after about a week or 10 days they can be stacked on top of each other, or used for construction. They are very heavy.  Cast:  Mauricio (Mauri), Avelino (Ave), Pelusa (Vontuti), and little Ratty the cocker,
