For several hours the ship traveled on, until it had come to a different sort of country. It was wilder and not so level, and there were a number of streams and small lakes to be seen. “Are you going to sail all night?” asked Jack. “No,” replied the professor. “I think we’ll descend very soon now, and camp out for a while. That lake just ahead seems to offer a good place,” and he pointed to a large sheet of water that sparkled in the distance, for by this time they had all gone back to the conning tower. The lake was in the midst of a wood that extended for some distance on all sides, and was down in a sort of valley. The ship headed toward it, and in a short time a landing was made close to shore. “Maybe we can have some fresh fish for supper,” exclaimed Jack as he ran from the ship as soon as the sliding door in the side was opened. “Looks as if that lake had some in it. It is not thick water like in that stream we stopped at,” he added. “I believe you’re right,” old Andy put in, as he turned back to look for some lines and hooks among his traps. He soon found what he wanted, and gave them to the boys, taking his trusty gun along for himself. While the professor, Washington, Tom and Bill remained behind to make some adjustments to the machinery, and to get things in shape for the night, which, they calculated would soon be upon them, Jack, Mark and Andy went down to the shore of the lake. The boys cut some poles from the trees, and baiting the hooks with some fat worms found under the bark, threw in. “Let’s see who’ll get the first bite,” spoke Jack. “I’m pretty generally lucky at fishing.” “Well, while you’re waiting to decide that there contest, I think I’ll take a stroll along shore and see if I can see anything to shoot,” Andy remarked. For several minutes the boys sat in silence on the bank of the lake, watching the play of the vari-colored lights on the water. Suddenly Jack felt a quiver on his line, and his pole began to shake. “I’ve got something!” he cried. Then his pole bent almost double and he began to pull for all he was worth. “It’s a whopper!” he cried. “Come and help me, Mark!” Mark ran to his friend’s aid. Whatever was on the other end of the line was strong enough to tax the muscles of both boys. They could hear the pole beginning to break. But for the excellent quality of Andy’s line that would have parted some time before. All at once there came a sudden slacking of the pull from whatever was in the water. And so quickly did it cease that both boys went over backward in a heap. “He’s got away!” cried Jack, getting up and brushing some of the dirt from his clothes. “There’s something that didn’t get away!” cried Mark, who had risen to his knees, and was pointing at the lake. Jack looked and what he saw made him almost believe he was dreaming.
