CHAPTER III

A MYSTERIOUS CAVE

At first Sam and Tom demurred to entering the cave--which looked dark

and forbidding. But Dick insisted that he was going ahead, and rather

than be left behind they went along.

"We'll light some kind of a torch," said the eldest Rover. "Got some

matches?"

"Yes, I brought along a pocketful," answered Sam. "Didn't know but what

we'd want to build a campfire this noon."

"We'll want one now--to dry our clothing by," said Tom. "Let us pick up

the driest of the sticks."

This they did, and having entered the cave, they made a good-sized

blaze. This sent a ruddy glow around the cavern, and as the boys moved

about fantastic shadows went dancing on the rocky walls, adding to the

weirdness of the scene.

From the fire each of the youths provided himself with a torch, and thus

equipped they moved around the cave with care, taking precautions not to

fall into any more holes. They soon found the opening on the

mountainside long and narrow and running downward.

"We don't want to get lost," cautioned Sam.

"Oh, we can always go back to the fire," answered Dick.

"Unless it goes out on us."

"It won't burn itself out for an hour--I saw to that before we left it."

As the boys advanced into the cave they came across a heap of bones.

Dick examined them carefully.

"Skeletons?" queried Sam, and his voice trembled slightly.

"Yes--of lambs and pigs," was the dry answer. "Somebody has been making

this a rendezvous and living on the fat of the land."

"Maybe that accounts for Jerry Burden's losses," suggested Tom. "He said

he lost a lamb last spring, and two pigs."

"Yes, and old Richard Feltham lost a pig and some chickens," added Dick.

"Maybe this has been a hangout for tramps."

"Do you think they are here still?" questioned Sam. "We don't want to

have any trouble."

"I am sure I don't know, Sam. But this proves one thing."

"That we can get out of the cave?"

"Exactly. See, here is an old coat and a pair of old shoes. Somebody has

been in the habit of coming here--and he wasn't in the habit of getting

in the way we got in."

They moved on, and soon reached a larger opening. Here they found a bit

of old harness and, further on, where the ground was soft, the tracks of

wagon wheels.

"Somebody has been in the habit of driving right in here!" exclaimed

Tom. "We are sure to get out!" and his face showed his relief.

"Hark! what's that?" cried Sam, and shrank back as a strange rumbling

was heard. "Is it an earthquake, or a landslide?"

"It's thunder, that's all," said Dick, a minute later, as they listened.

"To be sure--the storm was on us when we fell into the first hole,"

answered the youngest Rover.

"Perhaps we can be glad we are under shelter--if the storm is going to

be a bad one," came from Tom. "But, come on, I want to see daylight

again."

He moved on and then gave a cry of astonishment.

"Look!"

His brothers did so. On one side of the cave were piled thirty or forty

packing cases. The majority of them were empty, but three, directed to

one Jackson Dwight, Carwell, were full and nailed up.

"Well, I never!" murmured Sam. "Dick----"

"The freight thieves!" ejaculated the eldest Rover. "Don't you remember

what was in the paper before we went south, and what was in again only

yesterday? They have been missing freight from Carwell and Boxton and

half a dozen other stations for over a year. The thieves must have

brought their stuff here and then taken some of it from the packing

cases and carted it away again."

"It certainly looks like it," answered Tom. "Only three full cases left.

I wonder when these were taken?"

"Most likely only a short time ago," said Dick. "The cases look new."

"Do you suppose any of the freight thieves are around? If they are we

want to keep out of their way--if they are desperate characters."

They moved on, and then Dick called a sudden halt.

"I can see daylight ahead," he said. "And somebody is moving around. Let

us put out the torches."

His suggestion was speedily followed, and the three Rover boys advanced

with caution. At its outer end the cave became broader while the roof

was only about ten feet high.

"Hullo, here's another surprise," whispered Dick, as they came closer to

the opening. "Look at that!"

He pointed to one side of the cave and there the others saw an

automobile runabout standing and on the seat two men dressed for a tour.

They were talking to a third man, who was lounging against a front

wheel, smoking a brier-root pipe.

"Maybe they are the freight thieves," whispered Tom. "Let us get out of

sight and listen to what they have to say."

It was an easy matter to keep out of sight, for the walls of the cave

were very uneven at this point. They got behind a projection, and by

crawling up a rocky ledge managed to reach a point above and to one side

of the runabout and not over a dozen feet from it.

"Then you weren't going to stop here, Merrick?" asked the man leaning

against the wheel.

"Not now, Dangler," was the reply of the man with the pipe. "The storm

drove us in here."

"When do you expect to meet this Randolph Rover?"

"Very soon."

"He ought to be easy--he is so simple minded."

"Oh, I think we can work him right enough," put in the third man, who

was tall and thin-cheeked.

"Well, if you do, don't forget that I get my share, Pike," said the man

called Dangler.

"Haven't you always gotten your share?" demanded Pike.

"I suppose I have."

"And haven't we given you the information whenever any valuable freight

was coming this way?" put in the man called Merrick.

"Yes, and got your full share of the proceeds, while I ran the risk,"

growled Dangler. "It's getting dangerous--I'm going to quit--after the

next big haul," went on the man with the pipe.

"All right--as you wish," answered Merrick. "I wish this storm would let

up. The road will be something fierce for our runabout."

"And bad for my wagon," growled Dangler in return.

The boys listened to the conversation with deep interest. The reference

to their uncle amazed them, and they wondered what the two men in the

runabout had in mind to do. By their talk it was evident they meant to

accomplish something unlawful.

"They are going to play Uncle Randolph some trick," whispered Sam. "We

must get home and warn him."

"What we ought to do is to have the whole crowd arrested," answered Tom.

"They are all implicated in the theft of freight."

"That's the talk," said Dick. "The question is, How can we do it? We are

no match for those three men, and more than likely they are armed."

After this the three men conversed in such a low tone the boys could not

hear a quarter of what was said. But they learned enough to know that

Merrick and Pike were going to meet their uncle and play him false in

some way, and they heard the words "traction bonds" and "coupons"

several times.

"Uncle Randolph had ten thousand dollars' worth of traction company

bonds," said Dick. "He bought them only a short while ago. They pay five

and a half per cent. interest and he thought them a first-class

investment."

"Oh, we'll have to warn him," said Sam. "He is so open-hearted he would

trust most anybody."

Merrick had descended from the runabout and gone out of the cave. Now he

came back, said something to the others, and started up the auto. In

another moment he had the machine turned around. Then it spun out of the

cave and down a fairly good road in the direction of Carwell. The man

named Dangler followed the runabout to the road and watched it disappear

around a turn bordered by trees. The storm was now rolling away to the

westward and the rain had ceased.

"They have gone!" cried Tom. "Where to?"

"Perhaps to our farm--to see Uncle Randolph," answered Sam. "We ought to

follow them as quickly as we can."

"I think we had better capture the fellow left behind," said Dick. "We

ought to be able to do it."

"That's the talk," said Tom. "Sure we can do it, being three to one."

Dangler watched the runabout and then gazed up and down the mountain for

several minutes. Then of a sudden he started in a direction opposite to

that taken by the machine.

"He is going away!" cried Sam.

"Come on after him!" called his big brother, and ran from the cave with

the others at his heels. Just as he did this Dangler glanced back and

saw them.

"Hey, you!" he cried in consternation.

"Stop!" called out Dick. "We want you."

At this command Dangler was more amazed than ever. But of a sudden he

appeared to realize something of what had happened and commenced to run.

"Stop!" cried Tom and Sam, but at this the man only ran the faster.

"Come on--we've got to catch that rascal!" exclaimed Dick, and started

to sprint. The others followed as quickly as they could, and a rapid

chase along the mountain road ensued. But if the boys could run so could

the freight robber, and he made the best possible use of his legs until

he gained a side trail. Then he darted into this, and when the Rover

boys came up he had disappeared.

"Where is he?" panted Sam.

"He took to this path, but he isn't in sight," answered Dick. He was

almost winded himself.

"Come on, he must be somewhere around," put in Tom, and ran down the

path several hundred feet. Then he tripped over a fallen log and went

headlong in the bushes and wet grass. He got up looking tired out and

cross.

"We've missed him," announced Dick, rather dismally. "It's a pity, too.

He deserves to be put under arrest."

"I think we had better get home and warn Uncle Randolph," returned Sam.

"If we don't there is no telling what that fellow Merrick and that Pike

may do."
