Juan Carlo said. “Just think. This has been in my family for almost two hundred years.” Noah and Anthony had swum back to the Explorer without incident. Juan Carlo had said that a patrol boat had gone by. He had waved at the boat as he fished, and after watching the Explorer for a few minutes, the boat sped away. Anthony and Noah were now showing Juan Carlo the etched-glass pieces. “Where is the spyglass?” Juan Carlo asked. They had brought the spyglass tubing with them, storing it in the safe. Noah fetched it. He took the spyglass out of the box and handed it to Juan Carlo. “This must be how it works.” Noah watched in fascination as Juan Carlo carefully twisted the end of spyglass, loosening it. Then he popped the lens out. Juan Carlo switched it with the etched-glass piece with the metal rod in it. He attached the two etched pieces of glass to the rod. “Ingenious,” Anthony said in awe. He was piloting the boat as he talked, but he had a hard time keeping his eyes on the water ahead of him.
