To commemorate well-documented old sightings of huge sea serpents gamboling off the New England coast, Ibatoulline paints richly detailed scenes of wide seas and narrow shores, of small boats, monstrous writhing coils and astonished onlookers—to which Anderson pairs an old man’s reminiscence in verse: “The serpent was twirling, just chasing its tail, / And showed all intention of staying. / ‘Is it back in the deep?’ ‘Is it eating our sheep?’ / ‘I think,’ I said, ‘that the serpent is playing.’ ” Young monster lovers will share the wonder of this never-solved mystery, and applaud when a company of sea-hunter’s strenuous efforts to kill the monster yield only a large mackerel. A 19th-century tale presented in grand, 19th-century style. (afterword) (Picture book. 7-9)
