The animals prowled the two beaches, and Shann guessed they hunted shell dwellers, for at times they dug energetically in the gravel. Togi was busied in this way now, the sand flowing from under her pumping legs, her claws raking in good earnest.
And it was Togi’s excavation which brought Shann a first ray of hope. Her excitement was so marked that he believed she was in quest of some worthwhile game and he moved across to inspect the pit. A patch of brown, which had been skimmed bare by one raking paw, made him shout.
Taggi shambled downslope, going to work beside his mate with an eagerness as open as hers. Shann hovered at the edge of the pit they were rapidly enlarging. The brown patch was larger, disclosing itself as a hump doming up from the gravel. The Terran did not need to run his hands over that rough surface to recognize the nature of the find. This was another shell such as had come floating in after the storm to form the raw material of their canoe.
However, as fast as the wolverines dug, they did not appear to make correspondingly swift headway in uncovering their find as might reasonably be expected. In fact, a witness could guess that the shell was sinking at a pace only a fraction slower than the burrowers were using to free it. Intrigued by that, Shann went back to the waterline, secured one of the lengths he had been trying to weave into his failures, and returned to use it as a makeshift shovel.
Now, with three of them at the digging, the brown hump was uncovered, and Shann pried down around its edge, trying to lever it up and over. To his amazement, his tool was caught and held, nearly jerked from his hands. To his retaliating tug the obstruction below-ground gave way, and the Terran sprawled back, the length of wood coming clear, to show the other end smashed and splintered as if it had been caught between mashing gears.
For the first time he understood that they were dealing not with an empty shell casing buried by drift under this small beach, but with a shell still inhabited by the Warlockian creature to whom it was a natural covering, and that that inhabitant would fight to continue ownership. A moment’s examination of that splintered wood also suggested that the shell’s present wearer was well able to defend itself.
Shann attempted to call off the wolverines, but they were out of control now, digging frantically to get at this new prey. And he knew that if he pulled them away by force, they were apt to turn those punishing claws and snapping jaws on him.
It was for their protection that he returned to digging, though he no longer tried to pry up the shell. Taggi leaped to the top of that dome, sweeping paws downward to clear its surface, while Togi prowled around its circumference, pausing now and then to send dirt and gravel spattering, but treading warily as might one alert for a sudden attack.
They had the creature almost clear now, though the shell still rested firmly on the ground, and they had no notion of what it might protect. It was smaller, perhaps two thirds the size of the one which Thorvald had fashioned into a seagoing craft. But it could provide them with transportation to the mainland if Shann was able to repeat the feat of turning it into an outrigger canoe.
Taggi joined his mate on the ground and both wolverines padded about the dome, obviously baffled. Now and then they assaulted the shell with a testing paw. Claws raked and did not leave any marks but shallow scratches. They could continue that forever, as far as Shann could see, without solving the problem in the least.
He sat back on his heels and studied the scene in detail. The excavation holding the shelled creature was some three yards above the high-water mark, with a few more feet separating that from the point where lazy waves now washed the finer sand. Shann watched the slow inward slip of those waves with growing interest. Where their combined efforts had failed to win this odd battle, perhaps the sea itself could now be pressed into service.
Shann began his own excavation, a trough to lead from the waterline to the pit occupied by the obstinate shell. Of course the thing living in or under that covering might be only too familiar with salt water. But it had placed its burrow, or hiding place, above the reach of the waves and so might be disconcerted by the sudden appearance of water in its bed. However, the scheme was worth trying, and he went to work doggedly, wishing he could make the wolverines understand so they would help him.
They still prowled about their captive, scraping at the sand about the shell casing. At least their efforts would keep the half-prisoner occupied and prevent its escape. Shann put another piece of his raft to work as a shovel, throwing up a shower of sand and gravel while sweat dampened his tattered blouse and was salt and sticky on his arms and face.
He finished his trench, one which ran at an angle he hoped would feed water into the pit rapidly once he knocked away the last barrier against the waves. And, splashing out into the green water, he did just that.
His calculations proved correct. Waves lapped, then flowed in a rapidly thickening stream, puddling out about the shell as the wolverines drew back, snarling. Shann lashed his knife fast to a stout length of sapling, so equipping himself with a spear. He stood with it ready in his hand, not knowing just what to expect. And when the answer to his water attack came, the move was so sudden that in spite of his preparation he was caught gaping.
For the shell fairly erupted out of the mess of sand and water. A complete fringe of jointed, clawed brown limbs churned in a forward-and-upward dash. But the water worked to frustrate that charge. For one of the pit walls crumbled, over-balancing the creature so that the fore end of the shell lifted from the ground, the legs clawing wildly at the air.
Shann thrust with the spear, feeling the knife point go home so deeply that he could not pull his improvised weapon free. A limb snapped claws only inches away from his leg as he pushed down on the haft with all his strength. That attack along with the initial upset of balance did the job. The shell flopped over, its rounded hump now embedded in the watery sand of the pit while the frantic struggles of the creature to right itself only buried it the deeper.
The Terran stared down upon a segmented under belly where legs were paired in riblike formation. Shann could locate no head, no good target. But he drew his stunner and beamed at either end of the oval, and then, for good measure, in the middle, hoping in one of those three general blasts to contact the thing’s central nervous system. He was not to know which of those shots did the trick, but the frantic wiggling of the legs slowed and finally ended, as a clockwork toy might run down for want of winding—and at last projected, at crooked angles, completely still. The shell creature might not be dead, but it was tamed for now.
Taggi had only been waiting for a good chance to do battle. He grabbed one of those legs, worried it, and then leaped to tear at the under body. Unlike the outer shell, this portion of the creature had no proper armor and the wolverine plunged joyfully into the business of the kill, his mate following suit.
The process of butchery was a bloody, even beastly job, and Shann was shaken before it was complete. But he kept at his labors, determined to have that shell, his one chance of escape from the island. The wolverines feasted on the greenish-white flesh, but he could not bring himself to sample it, climbing to the heights in search of eggs, and making a happy find of a niche filled with the edible moss-fungi.
By late afternoon he had the shell scooped fairly clean and the wolverines had carried away for burial such portions as they had not been able to consume at their first eating. Meanwhile, the leather-headed birds had grown bold enough to snatch up the fragments he tossed out on the water, struggling for that bounty against feeders arising from the depths of the lagoon.
At the coming of dusk Shann hauled the bloodstained, grisly trophy well up the beach and wedged it among the rocks, determined not to lose his treasure. Then he stripped and washed, first his clothing and then himself, rubbing his hands and arms with sand until his skin was tender. He was still exultant at his luck. The drift would supply him with materials for an outrigger. One more day’s work—or maybe two—and he could leave. He wrung out his blouse and gazed toward the distant line of the shore. Once he had his new canoe ready he would try to make the trip back in the early morning while the mists were still on the sea. That should give him cover against any Throg flight.
