Rock formation, stone zoo and fish.

1. The organ pipes. They are basalt fractured into geometric shape in a dry riverbed. Rosey and I find some that have split so they clonk like bells when you hit them.

2. Rock art at Twfelfontein. It was used to teach San children how to recognise animals -- including the seals down on the skeleton coast. (Picture by Rosey Grant)

3. We haven’t eaten much fish -- Zanzibar was the last place -- but Francis has managed to find some frozen haddock in a supermarket. While we are lounging in the bar of a posh hotel drinking cocktails he cooks it with a crust of tomatoes and herbs. It is so delicious that even Louise, who doesn’t normally eat fish, enjoys it.
