The boys stopped at the orange trees only long enough to fill their game bags with the golden fruit, and hastened on to their ponies, fearful that, with no halters on, they might have turned back for Indiantown, but, much to their relief, they found the two animals browsing contentedly by the roadside. Each slung a turkey from one side of his saddle and a loaded game bag from the other, and, mounting, they rode on for their goal, the great lake. About four o'clock they rode out from a heavy growth of timber into full view of the broad, shining blue waters, and a few minutes later reined in their mounts on a high, grass-covered bank, shaded by big live oaks. Here they staked out their ponies to browse upon the sweet, tender grass, and, after a plunge in the cool waters of the lake, began their preparations for the night. Walter gathered great bunches of moss, and made soft beds at the base of a huge live-oak tree. Charley lit a big fire of live oak and pine, and, while it was burning down into a bed of glowing coals, he dressed and cut up the two turkeys, and soon had them frying and stewing in the pan and kettle they had brought with them. While Charley tended to the cooking, Walter gathered armfuls of dry wood and placed them in a circle around the oak, where he had made the beds. Before night fell everything was ready, and the boys sat down to a delicious meal of fried and stewed turkey and the eatables they had brought with them. They had eaten nothing since morning, and, when the meal was over, they were full enough and tired enough to be content to lie upon the grassy bank and simply gaze out at the glories of the sunset on the waters of the lake. When at last the light began to fail they watered their ponies and staked them in a fresh place, close to where they were going to sleep. This done, they started up the circle of fires around the tree and stretched out on their soft moss bed with a pleasant feeling of security, knowing that the slow-burning live-oak wood would keep the fires burning all night and protect them from all snakes and wild animals. "I have been wondering why that hole was made in that old fort," said Walter, as they lay on their backs gazing up at the stars. "It isn't deep enough for a well or a dungeon." "Maybe it was a hiding place for their treasures," suggested Charley, idly. "By Jove, I believe you've hit it," Walter exclaimed. "And that reminds me that I picked up something for a souvenir of my adventure before I climbed out. I couldn't see what it was, for the hole was dark and I had no matches. It was something hard, round and heavy. I have got it in my game bag now." "Get it out and let's see what it is," said Charley, interested. Walter rummaged in his game bag and brought out a round object, about a foot long and ten inches in circumference. "Looks like a piece of petrified wood," he said, as he handed it over for his chum's inspection.
