I have been enjoying “Fantasy Teachers”, as I enjoy everything else Adrian Mourby writes, but I fear that he knows even less about watersheds than Mr McChoakumchild (TES, June 22) when he quotes him as knowing “the watershed of every river in the world”. It is not possible for a river to have a watershed, for rivers flow only one way. Now that is a fact!
