Twice a day the River Thames recedes, revealing a muddy shoreline. Hobbyists known as mudlarks stroll the surface searching for objects that have found their way into the river over the centuries -- everything from ancient Roman jewelry to modern wedding rings. A new book about mudlarking describes the irresistible appeal of searching for treasures and the stories behind them. And: why do performers whisper the phrase Toi, toi, toi to wish each other well backstage before a show? Finally, what's the plural of octopus? Octopuses? Octopi? Or something else? Plus, schniddles vs. schnibbles, visiting vs. talking, fotched a heave, creature comforts, trade-last, a timely pangram, Doves Type, and a brain teaser about malapropisms.
