Scotty hooted in derision as Rick back-pedaled, then he put his bar down and swam to Rick's side. He scrawled on his belt slate, "Whre he cm frm?" Rick shrugged. It was a good question. They swam slowly around, looking for the grouper's hiding place and failed to locate it. Rick knew the big fish liked caves, rocky clefts, and the interiors of wrecks. This one must have a hole somewhere. He tried again, going right down to the bottom and crawling along with stomach touching the sand. Even so, he might have missed the hole if stirred-up dust from the fish's sudden departure hadn't indicated where it was. The hole, big enough for him to crawl through, was _under_ the wreck, hidden by rotted planks covered with marine growth. He hooted for Scotty's attention and showed it to him. He took his belt slate and wrote, "Way into shp?" Scotty nodded and wrote in his turn, "Too drk. Need lites." Rick nodded. For a moment he was tempted to try ripping off the planks with his bar, but he decided against it. Any disturbance might very well collapse the entire structure. He wondered whether the hole was just a shallow opening, or whether it actually led into the ship. No matter. They had watertight flashlights with their spare gear in the boat. They could find out on the next dive. For their remaining time underwater he joined Scotty in his assault on the stern of the ship. They were rewarded by finding what was evidently the interior of a cabin. Rick ripped off another plank, then jumped as Scotty hooted four times for danger. The cabin was the home of a fairly large moray eel! Both boys dropped their bars and grabbed for their spear guns, but Scotty held up his hand in a sign to wait. Rick did so, and saw the big eel emerge and swim rapidly toward the reef. Scotty had shown wisdom. The moray is hard to kill, and this one would have given them a battle that might have used up more air than they could spare. The water inside the cabin was murky. Rick looked at his watch. They had only a few minutes left. He wrote on his slate, "Sty dwn til rsrve wrning." Scotty nodded agreement. They watched as the water settled and the interior of the cabin grew clearer. Evidently it had been a very small cabin. There was a rotted frame that might once have been a single bunk, and a few broken, almost disintegrated boards that might have been a table. Mattress and bedding had long since vanished. Then Rick spotted a squarish shape under the ruin of the bunk and motioned to Scotty. They went in after it. The top crumbled under their touch and silt rose into the water around them. But Rick persisted and felt fabric under his hands. He pulled it out and recognized a seaman's jacket, brass buttons corroded and fabric nearly rotted through. Apparently they had found a sea chest, but their exploring hands discovered nothing but rotted fabrics.
