can we be sure, when we don't know anything about it."
"Baxter says your brother Dick has a map."
"Hasn't Baxter a map, too?" questioned Sam.
"Something of a map, yes, but it is not very complete."
"I'm glad to hear that," said Tom quickly.
"But Baxter claims the treasure for himself."
"Really?" said Sam sarcastically. "Well, let him claim what he pleases. If we find it, it will belong to us — don't forget that."
Again there was a pause. Jasper Grinder looked anxiously toward the outer cave, to see if Baxter or the guide were watching him. But the two were talking earnestly between themselves.
"I have a plan," began the former teacher of Putnam Hall, in a low voice, "a plan to aid you."
"What plan?" demanded Tom.
"Hush! not so loud — or they may hear you. I presume you know what sort of a fellow Baxter is?"
"Well, rather," said Sam dryly.
"He is planning to do you a great deal of harm. Now I think I can save you."
"Then save us," said Tom. "Or untie us, and we will save ourselves."
"You can't save yourselves. Baxter is strong, and that guide is a giant in strength."
"What do you propose?"
"I'm coming to that. But you must make me a promise first."
"What promise?"
"That half that treasure shall be mine when it is found."
"Half!" cried Tom and Sam together.
"Yes."
"We can't promise that," went on Tom.
"You don't want much," was Sam's comment.
"Isn't it worth something to be saved from Baxter's clutches? I overheard him tell the guide what troubles he had had with you in the past, and how you had been the means of sending his father to prison, and all that. Why, he would put you out of the way forever, if he could."
"And will you stand by, Jasper Grinder, and see that done?" asked Tom.
"No! no! But — but — he is his own master. Promise what I wish, and I will help you."
"We can't promise you half the treasure," said Tom flatly. "But if you will really help us, we'll promise that you shall lose nothing by the transaction."
At this instant Dan Baxter leaped to his feet and ran for his gun, while Bill Harney and Lemuel Husty did the same.
"Come out here, Grinder!" shouted the bully. "Somebody or some wild animal is around!"
CHAPTER XXIII
THE BLACK BEAR
"Somebody is coming!" ejaculated Sam. "I hope it is Dick, with Mr. Barrow!"
"So do I," returned Tom.
Without saying a word more, Jasper Grinder ran from the inner cave and joined Baxter and the guide. His face was pale, and he was evidently much disturbed.
Soon Baxter and his party were outside, and the Rover boys heard them moving up and down the gully. Several minutes passed, and then came a gunshot, followed by another.
"I hope they are not firing on Dick or Mr. Barrow," said Sam, with something of a shudder.
"I guess not," returned his brother. "If they were, we'd probably hear shots in return."
An hour went by, and then Dan Baxter and the others came back, the guide carrying several rabbits and a large fox. The rabbits were skinned and kept for eating, and the fox was skinned and the carcass thrown away.
Torn and Sam had expected Jasper Grinder to return to them, but if the former teacher desired to do this, he was prevented by Dan Baxter, who kept his companions close by him, around the fire.
Slowly the time went by until darkness was upon them. The fire was kept up, but Baxter screened it as much as possible, so that the glare might not penetrate to the forest beyond the gully and prove a beacon to guide Dick and John Barrow to the spot.
The boys were tired out, and soon Sam sank to sleep, with his hands still tied to the tree roots. Tom tried to keep awake, but half an hour later he, too, was in dreamland.
When the Rovers awoke it was not yet morning. All was dark around them, for the fire had burnt low. Sam roused up first, with a severe pain in his wrists and ankles, where his bonds were cutting him.
"Oh, my wrists!" he groaned, and his voice caused Tom to start.
"Is that you, Sam?"
"Yes. My wrists are almost cut in two!"
"The same here. I've slept like a rock, too."
"Is it morning yet?"
"I'm sure I don't know."
"What's going on in there?" came from Dan Baxter, as he leaped to his feet and caught up a gun.
"We are suffering from cuts of the ropes," said Tom. "It was an outrage to compel us to sleep in this fashion, tied up like mummies!"
"Oh, shut up!" growled Baxter, and then began to poke the fire. Soon it was blazing as readily as before, and then the light found its way into the inner cave, so that Sam and Tom could see each other once more.
Breakfast for the two prisoners was a slim affair of crackers, rabbits' bones, and water. Tom asked for coffee, but Baxter would not give it to them.
"You'll get no luxuries from me," growled the bully. "Be thankful that you aren't being starved."
While they were eating, Baxter and his companions held a low, but animated, conversation.
"We'll try it, anyway," Tom heard Baxter say, and that was all the Rovers heard. As soon as the meal was finished the party took up some of their traps and their firearms.
"Now, then, we are going out for a while," said Dan Baxter, coming up to the prisoners. "Take my advice and don't try to escape in the meantime. If you do, and we catch you, it will go hard with you; let me tell you that!"
"Are you going to leave us tied up?" questioned Tom dubiously.
"Certainly."
"Some wild animal may come in here and chew us up."
"We'll leave the fire burning — that will keep 'em away," returned the bully.
He would say no more, and in
