At nine fathoms the grass did thin out and leave the bottom exposed. It needed light, and the light was dimming. Good enough. But this had a consequence for Don, too. Just below the surface things had looked normal, for the limited distance he could see. Now the color red was gone. It had vanished somewhere between three and four fathoms, he decided; he hadn’t been paying proper attention. He had a red bag on his bicycle that now looked orange-brown. The effect was eerie and it alarmed him despite his awareness of its cause.
“S-steady,” he told himself. “The water absorbs the red frequencies first. That’s all there is to it. Next orange will go, then yellow, then green. Finally it will be completely dark.” He found his heart pounding, and knew he had succeeded only in bringing out another fear. He just didn’t feel safe in dark water.
He had somehow supposed that the ocean floor would be sandy and even, just like a broad beach. Instead it was a tangled mass of vegetation and shell—and much of the latter was living. Sponges grew everywhere, all colors (except red, now) and shapes and sizes. His wheels could not avoid the myriad starfish and crablike creatures that covered the bottom in places.
But at least he was getting his depth. The indicator showed ten fathoms, then fifteen, then twenty. Down far enough now to make headway toward the rendezvous.
But he had to go deeper, because the contour would have taken him in the wrong direction. He had been naive about that; if he tried to adhere strictly to a given depth, he would be forced to detour ludicrously. The ocean bottom was not even; there were ridges and channels, just as there were on land.
The medley of mysterious sounds had continued, though he had soon tuned most of it out. Now there was something new. A more mechanical throbbing, very strong, pulsing through the water. Growing. Like an approaching ship.
A ship! He was in the harbor channel for the commercial ships using the port of Tampa. No wonder he had gotten his depth so readily.
Don turned around and pedaled madly back the way he had come. He had to get to shallow water before that ship came through, churning the water with its deadly screws. He could be sucked in and cut into shreds.
Then he remembered. He was out of phase with the world; nothing here could touch him. He had little to fear from ships.
Still, he climbed out of the way. A ship was a mighty solid artifact. The hull would be thick metal—perhaps solid enough to interact with his bones and smash him up anyway. After all, the bicycle’s wheels interacted with the ocean floor, supporting him nicely. Could he expect less of metal?
The throbbing grew loud, then terrible. There was sound throughout the sea, but the rest of it was natural. Now Don appreciated the viewpoint of the fish, wary of the alien monsters made by man, intruding into the heart of their domain. But then it diminished. The ship had passed, unseen—and he felt deviously humiliated. He had been driven aside, in awe of the thing despite being a man. It was not a fun sensation.
Don resumed his journey. He followed the channel several miles, then pulled off it for a rest break. The coordinate meter said he had traversed only about four minutes of his fifty, and he was tiring already. He was wearing himself down, and he had hardly started. Cross-country underwater biking was hardly the joy that travel on land-pavement was.
Wouldn’t it be nice if he had a motorcycle instead of this pedaler. But that was out of the question; he had been told, in that single compacted anonymous briefing, that a motor would not function in the phase. So he had to provide his own power, with a bicycle being the most efficient transportation. He had accepted this because it made sense, though he had never seen his informant.
Something flapped toward him. Don stiffened in place, ready to leap toward the bike. He felt a chill that was certainly not of the water. The thing was flying, not swimming! Not like a bird, but like a monstrous butterfly.
It was a small ray, a skate. A flattened fish with broad, undulating, winglike fins. All quite normal, nothing to be alarmed about.
But Don’s emotion was not to be placated so simply. A skate was a thing of inherent terror. Once as a child he had been wading in the sea, and a skate had passed between him and the shore. That hadn’t frightened him unduly at the time, for he had never seen one before and didn’t even realize that it was really alive. But afterwards friends had spun him stories about the long stinging tail, poisonous, that could stun a man so that he drowned. And about the creature’s cousins, the great manta rays, big as flying saucers, that could sail up out of the water and smack down from above. “You’re lucky you got out in time!” they said, blowing up the episode as boys did, inventing facts to fit.
Don had shrugged it off, not feeling easy about taking credit for a bravery he knew he lacked. But the notion of the skate grew on him, haunting him retrospectively. It entered his dreams: standing knee-deep or even waist-deep in a mighty ocean, the long small beach far away, seeing the devilfish, being cut off from escape, horrified at the approach of the stinger but afraid to wade out farther into that murky swirling unknown. But the ray came nearer, expanding into immensity, and he had to retreat, and the sand gave way under his feet, pitching him into the abyss, into cold smothering darkness, where nothing could reach him except the terrible stinger, and he woke gasping and crying.
For several nights it haunted him. Then it passed, being no more than a childish fancy he knew was exaggerated. He never had liked ocean water particularly—but since he didn’t live near the shore, this was no handicap. For fifteen years the nightmare had lain quiescent, forgotten—until this moment.
Of course the creature couldn’t get at him now, any more than it could have in the dream. Not when its body was phased out, with respect to him, to that one thousandth of its actual solidity. Or vice versa. Same thing. Let it pass right through him. Let it feel the brushing of bones.
The skate veered, birdlike—then came back unexpectedly. It was aware of him. Without conscious volition Don was on the bike and pedaling desperately, fleeing a specter that was only partly real. The thing’s flesh might be no more than a ghost to him, but that very insubstantiality enhanced the effect. The supernatural had manifested itself.
Adrenaline gave him strength. By the time he convinced himself that the skate was gone, he was miles farther along. He had never been overly bold, but this episode had certainly given his schedule a boost.
Next time, however, he would force himself to break out his camera and take a picture. He couldn’t afford to run from every imaginary threat.
He had lost track of the channel. The meter now read eight fathoms. He had moved about three minutes west, and would have to bear mainly south henceforth. But he could use some deeper water, as patches of weed still got in his way.
But deep water was not to be found. Sometimes it was nine or ten fathoms, but then it would shrink to six. He had to shift gears frequently to navigate the minor hills and dales of this benthic terrain, for he was tired. The wind—really the currents of the water—made significant difference. Some spots were hot, others cool, without seeming pattern. Some were darker, too, as if polluted, but this could have been the effect of clouds cutting off the direct sunlight.
Don was tired of this. The novelty had worn off quite quickly. His time in the water had acclimated him; what could there be in the depths more annoying than this? He cut due west again, knowing that there had to be a descent at some point. The entire Gulf of Mexico couldn’t remain within ten fathoms.
His legs protested, but he kept on. Miles passed—and gradually it did get deeper. When he hit fifteen fathoms he turned south, for he was now almost precisely north of his target area.
There was still enough glow for him to see by, which was good, because he didn’t want to use his precious headlamp unnecessarily. Actually this objection was nonsensical, he realized, because it had a generator that ran from his pedaling power. But he was still having trouble overcoming his lifelong certainties: such as the fact that one could use a flashlight only so long before the battery gave out. Besides, a light might attract larger creatures. He didn’t care how
