"The word _light_ was put down in three different places."

"Did the man show us the night we were there three places where the light entered?"

"No, only two; but of course we didn't see everything."

"I do believe it was a drawing of the cave," said Martin. "But the next question is, who drew it. If we only knew that, we could find out the names of the fellows in the place."

"Nearly every person in the State has read that book," replied Owen. "I don't see what good it would do to get the names."

The boys were silent for some time.

The drawing which Owen had seen was the work of Jerry. When the trapper discovered the cave he went to the Tinker's house and offered to show it to him under certain conditions. Some of these conditions were written on the back of the page which had been burned. If Owen could have examined that page for five minutes he would have known the secret of the cave; for, while the few words scribbled there were unintelligible to others, they were sufficiently plain to any one who had visited the spot.

"I have something else to tell you about the cave," said Owen who was the first to speak. "You know old Bowen came up here the day after the shooting-match to inquire about Charlie; then he wanted to know where we slept the night we went to the cave."

"How does he know anything about the place?"

"That's just what I don't see; but from the way he asked the question I began to think he knew something about it. Father and mother talk about him every night. Father can't understand how it is that old Bowen's corn-crib has burned the last three years--and burned, mind you, just at the beginning of winter, when he had it full of corn."

"And what has that to do with the cave?" asked Martin.

"Nothing, as far as I can see. But father thinks that old Bowen is a rascal; that something will turn up one of these days and surprise everyone."

"If he does find out about the cave," said Martin, "he will charge that fellow who wants to buy it twice as much as it is worth."

"He will not find out from us. That man treated us kindly. We promised not to tell, and we must keep our promise."

"Just what I think about it, Owen! But I wish the fellow would hurry on and buy it. You see, we'll spend a whole day going through it."

"Do you think he will take us in as partners, because we've kept the secret so well?" asked Owen.

"I didn't think of that. We can be the guides to show the people around."

"But we must make him let us in as partners."

"Yes, we'll be guides and partners at the same time."

"I wonder whether he will make much money on it."

"And I wonder whether he will be able to buy it soon."

The boys continued for some time to build castles in the air, and to speak of their interest in the cave as if it were already a reality.

Their conversation was interrupted by Bounce, who ran out from the porch to the yard-gate barking furiously. They went to the door, but saw no one. It was a poor runaway slave who had caused the disturbance. He had been whipped most cruelly by his master, old Bowen, and threatened with death; and knowing that this was but the beginning of his sufferings, had resolved to attempt an escape. He was now concealed near the yard-gate, in the branches of a small tree. Later in the night he contrived to attract Mose's notice, who, pitying him in his distress, carried him to one of the hay-lofts.

CHAPTER XVI.

ON THE TRAIL OF THE RUNAWAY SLAVE.

Early the next morning, when old Bowen discovered that the slave had fled, he called his dogs and started in pursuit. It was easy to follow the trail, as it was still fresh. He urged his horse on as fast as it could go, shouted to the dogs, and cursed the fugitive slave. In his hand he held a long, blacksnake whip to administer punishment. His eyes sparkled with cruel expectation. His hand grasped the whip firmly, while on, on he rode. The hounds increased their speed. The trail was growing fresher. They would overtake the wretch soon. The heartless master plunged the spurs into his horse's sides, for the dogs were out-distancing him. They pa.s.sed the Howard house. No! They suddenly stopped in front of the yard-gate. They dashed on, ran wildly in several directions, and returned to the gate. Here they barked, jumped into the air, and scratched around a small tree. The trail ended here. Old Bowen rode up to the spot almost maddened with fury, for Zachary Howard, he thought, had given shelter and protection to his fugitive slave. What revenge! What revenge would be his! Now had his day of retaliation come!

He would drag the slave out from his place of concealment, would scourge him in Howard's presence--scourge him until the ground was covered with blood, and the more he writhed and cried for mercy, the harder the lash would fall. If Howard pleaded for him, his punishment would be prolonged. Oh! revenge, cruel, terrible revenge! He leaped from his horse, and, grasping his whip firmly, started toward the house. Mr.

Howard, who had been disturbed by the noise, came out to meet him.

"Zach Howard!" cried the raging master, "show me where my slave is concealed. You can't deny it, you have hid him. But I'll find him, and whip him here while you look on--whip him until there is not a drop of blood left in his body. I'll whip him and show you that he is my slave, not yours! Where is he? Bring him out. Zach! Bring him out!"

"There is no slave of yours around these premises," replied the astonished farmer.

"A lie! My dogs tracked him to that tree in front of your gate! Those dogs never fail, Zach, never fail!"

"If the slave was tracked to that tree, Mr. Bowen, he can certainly be tracked farther."

"No sir!" growled old Bowen. "He stopped right there, was helped down by some one, carried away and hid. I have been in this business too long to be deceived by a little scheme like that."

"Strange that this could have happened without my knowing anything about it," said Mr. Howard.

"Well, it did happen, Howard. It happened last night, the trail shows it plainly--shows that he came to the tree and climbed it. The trail doesn't start any place near the tree, and this shows that the cussed negro was helped by some one."

"And why do you think he climbed the tree?" asked Mr. Howard.

"To throw me off the track. The stupid fool! I saw through the trick at the first glance."

"I think I can explain the whole affair."

"How?"

"Do you see that poplar?"

"Yes."

"Do you notice that large limb reaching out toward the tree which you say the negro climbed?"

"Yes. What of it?"

"Don't you think that the negro could have climbed from the small tree into the large one?"

"Possibly. But what did he do when he got in the large tree?"

"Don't you notice that from the other side of the poplar there is another long branch extending over my carriage-house?"

"Yes! yes!"

"Don't you see plainly that he could have climbed on the roof?"

"Yes! What then?"
