Euell Gibbons. He wrote a series of living-off-the-land books back in the 1960s ( see post #461 ). He did the late-night-talk-show circuit for a while, and a commercial for Grape-Nuts that started: "Did you ever eat a pine tree? Many parts are edible."
His books are a lot of fun, with history, personal stories, lore from cultures around the world, and recipes for stuff you didn't know was edible, let alone tasty. Living in Florida, I'm partial to "Stalking The Blue-Eyed Scallop", and especially his "Euell Gibbons' Beachcomber's Handbook", about living off the land & sea in Hawai'i. They are (or were) available in field-guide editions with waterproof covers. I remember buying the whole set at Walden Books in 1973, right after getting out of the Navy. I had found "Scallop" in a base library - made me *so* homesick for our family fishing & snorkeling trips to the Keys.
Kals' books are good; the "Practical Navigation" is a bit dry at times, but better than anything else I've read. "Boating" is in a more personable style.
"Riddle of the Sands" is a terrific book. Much as I like some of Michael York's films, the movie did not come close to doing the book justice. Being set pre-World War I, when there were no engines in small boats, it would probably drive some of our more technophilic shipmates mad with frustration.
Looks like you saved enough for another book. Enjoy!
