This story is what the children call ""slow in starting"". Roger and his sister have mild adventures en route to their summer cabin on the lake. I doubt that young readers will like these children --Roger who, at nine, is still afraid to swim and his sister who is a nagging prig. Things get better, though, when Roger has a dream wherein he joins his two pet fishes on an underwater jaunt. This bit has an almost Alice-in-Wonderland quality and it's a pity it lasts only a few chapters. The upshot of the dream is that Roger, when he wakes, bravely dives into the water and finds he can swim -- a lesson in courage which parents will appreciate. Children will like the story well enough, but only those interested in fish, will go for it in a big way.
