How to...find south with a watch

Not everyone likes to discuss it but here goes. Number twos - I realise toilet paper doesnt break down too well and should be carried out, having a bag of used loo roll for 5 days in my rucksack on a hot summers walk doesn't bear thinking about. I'm a big fan of moss, sphagnum moss if I can find it, slightly moist and as a bonus it has mild antiseptic properties. I now never carry loo roll and have never failed to find something that equals a bit of andrexs' finest...

just what im looking for will take his advice this coming weekend nice one!
