He had intended to swim right up to one of the boys, hoping his approach would not be noticed and his efforts at contact marked by swirling water or his subject's friends -they were indulging in acts of considerable violence as they swam and plunged. However, it speedily became evident that only luck would bring him in contact with one of the creatures, since they swam much more rapidly than the Hunter could; and, realizing this, he found what seemed to be an excellent means of making an under* cover approach. He suddenly noticed beside him a large jellyfish, bobbing rather aimlessly along after the manner of its kind; and with his attention thus diverted, he saw that there were quite a number of the things in the vicinity. Evidently the bipeds did not consider them dangerous or they would not be swimming here.

Accordingly, the Hunter altered his form and method of locomotion to agree with those of the medusae and approached more slowly the area in which the boys were playing. His color was slightly different from that of any of the other jellyfish but these, in turn, differed among themselves, and he felt that shape must be a more important criterion than shade. He may have been right, for he got almost up to one of the bipeds without apparently causing any alarm. They were fairly close together at the moment, and he had high hopes of making contact-he did, in fact, with a cautiously extended tentacle, discover that the varicolored integument covering a portion of their bodies was an artificial fabric-but before he could do any more, the subject of his investigation slid to one side and moved several feet away. He gave no sign of alarm, however, and the Hunter tried again. The approach ended in precisely the same fashion, except that this time he did not get so close.
