I wonder who ever first thought of eating a tree. This boy does not know.
Here is a filtering trough being constructed.
The mat is completed to catch the pounded-out fibers.
Completing the trough (placing the collection basin in place and damming the ends to prevent run-off).
Pounding the sago from the felled and skinned and split trunk into fibers that can be filtered.
Running water through the trough in order to filter the fibers. The women squeeze the fiber and presses it to get as much good, edible sago out as possible.
The silty water then collects here, the water is later poured off and the orang silty "mud" of the sago is collected and dried and becomes brick-like (where it waits to be reconstituted and cooked and eaten like bread).
Looking at the orangish "mud" from the filtered sago collected at the bottom of the collection basin (itself made from parts of the sago tree). You can see the demarcation where the fibers are dammed up in the steeply leaning portion of the trough and the final section where there are no fibers but only orangish silt. Later this orang water will be carefully dumped and the fine silty sago on the bottom will be dried.
Woman pouring water in the trough to filter the sago and pressing out the water so that the silt runs into the collection basin.
The finished product - like a dry, bland pancake.
