1) June 28. When I woke up after sleeping for almost two days, I felt quite refreshed so I got up and decided to prepare myself for the night ahead. The first thing I did was to fill a large bottle with water, and put it on the table, next to my bed; then I grilled some of the meat on the coals, but I only ate a little bit.
2) I walked about, but was still very weak, and I felt miserable about my sickness. At night I had three of the turtle's eggs, which I roasted in the ashes for supper.
