Jane Thomas doesn't go native in the summer, her father says; she 'goes biological'. As a scientist, his interest centers in the Marine Laboratory at Woods Hole, but Jane's enthusiasm goes beyond his. Planaria and Nereis are her familiar friends. She keeps crabs under her bed, and uses dead fish for the punishment of her enemies. Ellen, the college freshman who has undertaken to keep Jane out of trouble for the summer, soon finds that she is the one who is being taken in hand. Life is never dull with Jane—nor quite safe—so Ellen is rapidly initiated into the pains and delights of the scientific vacation. Jane and Ellen are real girls and very likable. Their adventures together make exciting and fascinating reading for girls of twelve to sixteen.
