On a recent visit to Barter Books in Alnwick, Northumberland (a must-visit if you're in the area - allow at least half a day, as it's no ordinary bookshop), I acquired a book as part of my barter called Two Canoe Gypsies, subtitled Being an Account of an Eight Hundred Mile Canal Voyage through Belgium, Brittany, Touraine, Gascony and Languedoc. It was published in 1933. I've only dipped into it so far (there are other bartered books ahead of it), but it seems a fascinating account of the European waterways between the wars, with some interesting pictures, which are 'Copyright National Geographic', the author, Melville Chater being a National Geographic photographer. I reproduce just one of them here, but if anyone thinks that this will bring the wrath of National Geographic down on CWDF, please feel free to delete. Has anyone else come across this book?
