12/14/19 Sat.  Saturday was a rest and recovery day with no hiking.  Worked on grading in the morning since this last week was our finals week at the college.  In the afternoon the Embara tribesman showed us how they make tattoo ink and gave us all temporary tattoos (should last a week).  He took this fruit that grows on a palm-like tree and peeled it with a knife before it was ripe, when it was still green.  Then he put it in a rag and squeezed the fruit’s juice out.  The juice looked grayish.  The pulp was whiteish.  The tribesman showed us some tools or stick-like flexible structures that are made from plant material that he uses to apply the juice to the skin.  The juice is applied to the skin and looks light gray when it goes on but darkens by the next day to black. The tribesman let us tell him if we had a preference for a design.  I requested something associated with water.  My tattoo has a river winding up my arm that branching into two below the elbow.  The river has 4 trees around it representing the forest.  The river could be the Culvert stream with our unnamed stream joining it.  It apparently hadn’t dried completely by time I went to bed at 10 because in the morning some of the top of the river was smeared unto my upper arm (I’m now thinking of the smear as the unattainable waterfall we couldn’t get to).
