Danny Dunn on the Ocean Floor, by Jay Williams and

Raymond Abrashkin (Macdonald, 13s. 6d.), is much more pedestrian, though it uses exciting material, such as all-wise professors and the strange fish to be found in the depths of the sea. I imagine that this book will appeal largely to boys. It certainly fuses, rather skilfully, instruction with mystery. The Search in Summer (Angus and

Robertson, 18s.), is another children's novel which roves far in the matter of place—this time to Tasmania. One would have thought the setting here engendered quite enough excitement without the author, James Poynter, having recourse to treasure-hunts. even if they are very unusual ones, Strange, too, that the story, on the whole, fails to be particularly imaginative or gripping.
