Another twist of Mr. Slobodkin's imagination compasses the gap between fantasy and reality and back again as Cynthia, the little mermaid who could not sing, becomes a natural fog warning for errant sailors. Though the sailors do not believe in mermaids nor the mermaids in sailors, Cynthia's singing teacher at the Blue Rocks school has her foggy-voiced pupil sing the school song every time the weather is bad. The sailors, whenever they hear the hoarse noise, give the area a wide berth. Watery colored pictures by the author show the maids, pretty and prim with their little tails flipping about in the sea scapes. Weak stitching in trade edition.
