Description: The first portion of the film " O-Musin" deals with the methods of sharpening the jage eken, or stone to be used for cutting a tree. Kurelu and Wili prepare the stones by rubbing them back and forth over the jage man or sharpening rock at the place Kolopale on the Sompam river. The stones are rubbed against the jaga man in an inverted position from using position as another man, Apmabaga, splashes water over the stones to aid the abrasive action. The stones are rubbed until the crescent shaped edge is smooth and sharp. The total process usually takes approximately a quarter of an hour to complete. The activity of the men is watched by a daughter of Kurelu, named Wolokhe. The second portion of the film depicts the actual tree cutting using the stone adze or jaga. The expression for tree- cutting is "o-musin". The tree, a hard red wood, is known as jual by the local people and measures approximately 10 inches in diameter. The tree is cut by Wili and a young man Abasue, at about shoulder height. The actual cutting takes about 18 minutes to complete, allowing for perhaps one drink during the work. At one point Abasue, the younger man, must be shown the proper method of cutting and assisted by the older Wili. Following the conclusion of the tree cutting, Kurelu is depicted eating the traditional food, the sweet potato and the jaga is seen in its usual carrying position over the shoulder by Wili. Another man, Nakleak, is also shown after the tree felt.
