"I don't know, yet. The best we can do is to keep away from the lights of the houseboat." Stroke after stroke was taken in dire desperation, and after a while they had the satisfaction of seeing the lights of the houseboat fading away in the distance. All was gloom and mist around them and they stopped rowing, not knowing in which direction to turn next. "We are lost on the river," said Nellie. "Yes, but that is better than being in the hands of our enemies," was Dora's answer. "Yes, Dora, ten times over. But what shall we do next?" "Let us try to row crosswise with the current. That is sure to bring us to shore sooner or later." This they set out to do, and after a while felt certain that they were drawing close to the river bank on the north. "We are getting there!" cried Nellie. "Oh, Dora, aren't you glad?" Scarcely had she spoken when they saw a light behind them, and a long launch came unexpectedly into view. In the bow stood Dan Baxter with a lantern. "I thought I heard their oars," cried that rascal. "Here they are!" "Pull, pull, Nellie!" cried Dora. "Pull, or we shall be captured!" Both of the girls rowed with all their strength, but before they could gain the shore, which was now less than two rods away, the launch came up and made fast to the rowboat. "Might as well give it up," said Dan Baxter, sarcastically. "It's no use, as you can see." "Oh, Mr. Baxter, do let us go!" pleaded Nellie, more terrorized than ever before. "Not much! You have got to go back to the houseboat." At this Nellie gave a loud scream, and Dora immediately followed with a prolonged call for help. "Shut them up!" came from Pick Loring. "There are a whole lot of people living around here." Without answering, Dan Baxter leaped into the rowboat and took Dora by the arm roughly. "If you don't shut up, I'll gag you!" he cried. "Let me go!" she said, and struck at him feebly. While this was going on Pick Loring came over and took hold of Nellie. "Tow us along, Sculley!" called the horse thief. "Get back to the houseboat as soon as you can." "What's the matter out there?" came in an unexpected call from the shore. The speaker could not be seen. "Help us!" shrieked Dora. "We are two girls and some men are carrying us off." "You don't say so!" ejaculated the speaker on shore. "Tell the Rover boys!" called out Nellie. "Dan Baxter is taking us down the river on the houseboat." "Save us, and we will pay you well," added Dora, and then Baxter's not over cleanly hand was clapped over her mouth, and she could say no more. Loring's hand was likewise placed over Nellie's mouth, and then the launch began to tow the rowboat back into midstream once more. The poor girls were utterly disheartened and dropped back on the seats in something close to a faint. "This is a mess," growled Dan Baxter. "Have you any idea who that was that called from the shore?"
