keach: in a test pit the team looks for buried structures. do still more houses lie beneath the sugar cane ? after days of digging, the test pit is three meters deep. the workers have found a large piece of wood. it may be the remains of a roof timber. ¿qué han encontrado? ahí está. ¿en la esquina? no. eso no. acá. aquí está. ahí. iotro grande! keach: using the test pit method, the team finds evidence of at least seven buried structures. right there. keach: full excavation begins. slowly, meticulously the team begins to remove the volcanic ash. weeks later, the ancient floors emerge, yielding the first clues of how these rooms were used. so, anyway, we're really glad to find this. it's certainly not any one of your super-elegant, towering pyramids like at tikal, but, for our purposes, super important to know where they actually did their cooking. and they've got round-bottom pots. and what they'd do is they'd rest one of those round-bottom pots on the three points of contact and put the firewood in from the side. the people in the area still

keach: mr. sakkout is employed by market officials.he occasionally serves as auctioneer if asked but in the main, his job is to settle disputes. everyone in the fez tanning industry is dependent upon others. the man who dries the finished skins cannot function without those who remove the hair, or without any of the other specialists in the trade. with so many dependent upon forces outside their control new institutions inevitably develop. in fez, every specialty within the tanning industry has its own guild or craft association. the guilds serve their members by setting standards restricting membership and controlling prices whenever possible. but perhaps more importantly guilds represent the interests of their members before various authorities. sometimes this means catering to the public relation needs of the government. steward of the tanner's guild is sherrif mohamad alaoui. interpreter: if the king is coming or if someone from america or france is coming, we are asked to go out and show our happiness our appreciation that they co
