“I—­I haven’t hurt anybody, sir.”

“All right, old man; keep still.”

“But I—­I don’t understand?”

“You will, later on.”

Dan Baxter had the straps of the old harness ready and with them he fastened Captain Starr’s hands behind him and also tied his ankles together.  Then he backed the commander of the houseboat to a post and secured him, hands and feet.

“Now then, don’t you make any noise until to-morrow morning,” was Dan Baxter’s warning.  “If you do, you’ll get into trouble.  If you keep quiet, we’ll come back in the morning, release you, and give you a hundred dollars.”

“Give me a hundred dollars?” questioned the captain, simply.

“That is what I said.”

“Then I had better keep quiet.  But the houseboat—­”

“The houseboat will be left just where it is.”

“Oh, all right, sir,” and the captain breathed a sigh of relief.  That he was just a little simple-minded was beyond question.

Leaving the captain a prisoner, Dan Baxter and Lew Flapp made their way with caution toward the houseboat.  As they had surmised, the Dora was now totally deserted.  They leaped on the deck and entered the sumptuous living room.

“This is fine,” murmured Lew Flapp.  “They must be living like nabobs on this craft.”

“You’re right.  A piano and a guitar, too.”  Baxter passed into the dining room.  “Real silver on the table.  Flapp, we’ve struck luck.”

“Sure.”

“That silver is worth just so much money,—­when we need the funds.”

“Would you sell it?”

“Why not?  Didn’t I tell you the Rovers robbed my father of a mine?  This isn’t a fleabite to what they’ve got that belongs to us.”  From the dining room the young rascals passed to the staterooms.

“Trunks full of stuff,” observed Flapp.  “We shan’t fall short of clothing.”

“I hope there is money in some of them,” answered Dan Baxter.

“Hadn’t we better be putting off?” asked Flapp, nervously.  “Some of them may be coming back, you know.”

“Yes, let us put off at once.  This mist that is coming up will help us to get away.”

Leaving the stateroom they were in, they went out on deck and began to untie the houseboat.  While they were doing so they heard the sounds of two horses approaching.

“Somebody is coming,” said Flapp, and an instant later Dora and Nellie came into view.  Nellie had her skirt badly torn, and it was her intention, if she could locate the houseboat, to don a new skirt before she returned to where Tom and Dick had left them on the highway.

“It’s a pity you fell and tore the skirt,” Dora was saying.  “But I suppose you can be thankful that you did not hurt yourself.”

“That is true.  But the boys will think I can’t ride, and—­Oh!”

Nellie came to a sudden stop and pointed to the houseboat.

“Dan Baxter,” burst from Dora’s lips.  “Oh, how did that fellow get here?”
