The International Geophysical Year is making its impression --even subtly in picture story books. The Pelican is a marine exploratory ship. Little Peter Pokeberry, nephew of the captain, strikes up a friendship with the sensational creature caught by the crew -- a marina (Blonk, for short). Peter supplies the Blonk with hot dogs. But ashore when Professor Pokeberry displays the Blonk at the Institute, Peter sympathizes with the captive, a sort of fishy seal, and arranges for his escape with a dishpan suspended from balloons. At the last moment though the Blonk capsizes his aircraft in mid-flight and returns peacefully to the Oceanarium where he can study all the people who come to see him. On the strength of broad current interest in exploration of the cosmos, this slight fantasy with two-color illustrations by the author, may catch on.
