The water was quite clear, so it was not necessary to keep an eye above the
surface to direct the stalk. The mass of jelly quickly molded itself into an
elongated, fishlike shape with an eye in front, and the Hunter swam toward the
boys as rapidly as he could. In one way, he reflected, it was really easier to
see under water. He could use a concave lens of air, held in shape by a film
of his own flesh, which was far more transparent than an optical system
composed entirely of the latter substance.
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.
He tried each of the other boys in turn, with the same annoying near-success.
Then, puzzled by a phenomenon which seemed to be exceeding the generous limits
of the law of chance, he drifted a short distance away and watched, trying to
learn the reason for it. Within five minutes he realized that, while these
creatures seemed to have no actual fear of jelly-fish, they sedulously avoided
physical contact with them. He had chosen an unfortunate camouflage.
Robert Kinnaird avoided jellyfish almost without conscious thought. He had
learned to swim at the age of five, and in that and each of the nine
subsequent years of his life he had enough first-hand experience with their
stinging tentacles to assure his avoiding their company. He had been fully
occupied in ducking one of his companions when the Hunter had first touched
him, and even though he had dodged hastily on noticing the lump of jelly in
the water beside him he had not really thought about the matter -- if he did,
it was merely a brief reflection that he was lucky not to have been stung. He
forgot the incident promptly, but his attention had been sufficiently diffused
by it to prevent the thing's again approaching so closely.
About the time the Hunter realized what was wrong, the boys grew tired of
swimming and retired to the beach. He watched them go in mounting annoyance,
and continued to watch as they ran back and forth on the sand playing some
obscure game. Were the mad creatures never still? How in the Galaxy could he
ever come in contact with such infernally active beings? He could only watch,
