I'm just about to finish a Virago/Beacon Traveler, Unbeaten Tracks in Japan by Isabella Bird who took an interpreter with her in the summer of 1878 and set off to visit the Ainu (Ainos). I have thoroughly enjoyed her detailed observations of her adventure and have nothing but respect for this intrepid little woman. She writes about crossing a flooded river, "The coolness with which the Aino guide took to the water without giving us any notice that its broad, eddying flood was a swim, and not a ford, was very amusing." That's typical and makes me happy to read about it in my own warm, dry house!
