Traditional sesame oil mill (Arabic: “assara”) carved out of a tree trunk. Note how the pounder in the middle of the mill is connected to the lever loaded with stones in the foreground. When the camel moves around the mill, this increases the force the pounder exerts on the sesame seeds and thereby increases the amount of oil extracted. The extracted oil is sold in the market (souq).
Jebel Si area, Northern Darfur.
