SCOUT TACTICS.

"Gee! that ought to settle the business!" breathed Jimmy, as he continued to stare at the three workers.

These men seemed as busy as beavers, passing from crevice to crevice, and managing in some way to insert what were very likely pieces of rich copper ore, brought from some distant and well-known mine, for the purpose of deceiving any one sent up to inspect this new venture.

Ned himself felt that he could have no better evidence of fraud than was exhibited in the actions of these laborers. He knew that if this scene was incorporated in his report, it would sound the doom of the intended big deal, whereby a million, perhaps many of them, was to pass into the hands of the swindlers.

And knowing this, Ned was also aware of the fact that should the employees of the company running the game learn that the scouts had actually been inside the mine, and watched its being so beautifully "salted," they would realize that desperate tactics must be employed in order to silence the spies.

That might mean either their speedy dispatch, or being kept prisoners in that region so far away from civilization until the deal had been put through, and the vast amount of cash changed hands.

He could easily enough imagine these desperate scoundrels making him sign a glowing report declaring that the property was fabulously rich. Plainly, then, it would be greatly to the advantage of the scouts to get out of the mine without being discovered.

"Well, do we go on and see what the fellows have to say for themselves?" asked Frank, chafing under the delay.

"If we have to do that, please let me take care of old Blackbeard, Ned," urged Jimmy, who seemed to have taken an especial dislike toward the giant, whom he had been comparing with the old-time pirate.

"We'll back out!" said Ned, shortly.

"Seem to have seen enough, eh?" Jack whispered, with a little vein of disappointment back of his words, just as though he had really been hoping they might see some lively action, while up in this "neck of the woods."

"When your father learns about this job, he'll want to throw up his hands and wash them of the whole business," the other assured him.

"Then it's no use going deeper," admitted Jack.

Of course, all this conversation was carried on very cautiously. No one dared to raise his voice above the softest sort of whisper; and usually spoke directly into the ear of the chum he wanted to address. On this account, the workers not far away did not suspect the presence of interlopers, or that their actions were being carefully noted.

Ned managed to let the two guides know that it was now up to the party to execute a masterly retreat. If they could quit the mine as easily as they had entered, it would be a big feather in their caps.

All of them were immediately in motion, and after the bend in the passage had been negotiated they could once more use a light. As before, Ned brought his means of illumination into service, and guided by the soft white glow ahead, that showed up all inequalities of the path, they set out for the exit.

They had gone perhaps half-way, when Ned stopped to listen. All of them could hear what had come to his ears. Shouts without were sounding the alarm. Plainly, something must have occurred to excite the few who had been in the tented settlement. Perhaps after all some one witnessed their entrance to the mine, and had hurried to the camp with the news. There were two or three men there, as Ned had noted before; and these were now trying to communicate their discovery to the three miners engaged in "salting" the works.

There seemed to be only one course open to the scouts, and this was to make all haste possible to attain the exit. Here, they might sally forth, and by taking advantage of the confusion cause the few guards to disperse, by firing a volley over their heads.

This plan flashed into the head of the young leader of the explorers, as he listened to the shouts that were ringing forth.

"Hurry along, fellows!" he urged his companions, knowing only too well the value of prompt action in a case like this. "We must rush the opening, and scatter that howling bunch like wolves. Shoot to frighten, then if that doesn't work, try to cut them in the legs. Understand?"

They all answered in the affirmative, even Jimmy showing that he had caught the idea. And bent upon carrying it out, without the loss of even a second, the party pressed forward eagerly.

Just for another minute, and then they met with a sudden surprise, that came as unexpectedly as lightning might from a clear sky.

As though some giant hand had brushed them all over into a heap, so the five scouts and their two husky guides were sent headlong to the rocks, some of them receiving bumps that would prove more or less painful later on.

There was no mystery about the matter, because accompanying their upset had come a loud explosion that sounded doubly severe to them, since they were underground.

Plainly the conspirators had looked far enough ahead to make ready to entomb any prowling visitors who might succeed in gaining access to the mine, and learn something of its secrets. They had a charge of blasting powder, or possibly a dynamite cartridge, placed so that it could be fired with ease.

"Wow!" exclaimed Jimmy, struggling half erect, "who hit me with that brick?"

"What happened, Ned?" asked Teddy, almost dazed from the way his head had collided with a hard rock, causing him to see about a million flashing stars in that one second of time.

"They've fired some sort of explosive, to seal up the exit of the mine!" broke from Jack, who was quick to guess the appalling truth.

"Then we're shut up here like rats in a trap, is that it?" persisted Jimmy, now so astonished that he even forgot to rub the back of his head where the seat of the pain seemed to be located.

"I don't know," said Ned, "but we can soon settle that by pushing on."

"What if another bomb lets go?" Teddy inquired.

"Small danger of that happening," the leader assured him; "but anyhow we'll have to take the chances. Come along, everybody!"

That was Ned's way of doing things, and proved him to be the right type of leader, capable of winning the respect of his patrol. Seldom had any of the scouts heard him tell them to "go on" when there was a spice of peril in the air.

They were not long in finding out the dismal truth. Indeed, as they advanced along the tortuous passage, the air became more and more foul with the odor of burnt powder. And, finally, the light from the several electric hand-torches disclosed the presence ahead of a mass of fallen rock and dirt that effectually filled the narrow passage.

The boys stared at the barrier in more or less dismay. It effectually cut them off from making their exit, and so far as they knew there was no other means of leaving the mine.

Jimmy started in to lifting several of the rocks and tossing them aside. With his customary zeal, he fancied that if they all got to work they might in a short time bore through the barrier.

"Be careful there!" warned Jack, as the action of the "busy bee" dislodged several other masses of rock, and Jimmy had a narrow escape from being crushed.

"Yes," added Ned, hastily, "better leave that alone for the present, Jimmy. For every pound you take away three will drop down, because you can see how the shock has loosened everything above you."

"But my stars! we ain't goin' to stand for being sealed up here like a lot of old mummies, are we?" gasped Jimmy. "Why, whatever would we do for grub; and then a feller wants to have a fresh drink every once in a while? Ned, we've just got to break out of this!"

"You bet we do!" added Frank, who did not like the bitter prospect any more than the one who was putting up such a savage protest.

"Tell me, how you're going to do it then," said Teddy.

Neither of the scouts answered. The fact of the matter was that while they were so vehement in their declaration not to stand, they did not have the least idea how the trouble might be remedied.

As usually happened, it became more and more evident that they must depend on Ned to lead them out of the wilderness. Instead of talking he had been doing some hard thinking; and was now able to suggest a plan.

"I don't know whether there can be anything in it boys," Ned started in to say, "but it seems queer that they should shut their companions up in here with us, if there wasn't some other means for escaping. Our plan then is to hurry back, and try to get in touch with that giant and his bunch. By now they'll have taken warning, and be hustling for the open air."

"Whee! then we'd better be on the jump," Jimmy jerked out.

All of them saw the necessity for prompt action. Now that Ned had suggested such a possibility they could understand how it might be just as he said. And if those toilers were already making in hot haste for the second exit, the sooner the scouts got close in touch with them the better.

They had already been over this ground two times, so that they should know it fairly by now. Every fellow had his electric light in service, gripping it in one hand, while his gun was held in the other.

In this fashion, then, they reached the bend around which they had peered at the trio of industrious "salt" workers.

All was as black as a pocket there now.

"Why, they're gone!" burst out Jimmy, just as though he had an idea the miners, after hearing the horrible crash of the explosion, would be kind enough to linger there, so as to show the intruders the back door of the mine.

"Keep right on going," said Ned, "we've got to overtake them, if we can do it."

"Guess, that'll save more or less trouble in the end," admitted Jack; while Teddy and Frank were heard to mutter their approval of the scheme.

Indeed, it was a rare occurrence for any of the scouts to radically differ from their leader. Somehow, Ned Nestor seemed capable of judging things just right, and these comrades tried and true had come to rely on his way of looking at the solving of knotty problems as well nigh perfect.

They passed the place where the men had been working. Perhaps some of the lads might have been glad of a chance to stop and see how this clever trick of making a mine appear ten times more valuable than it really was, could be carried out; but there was no time for delay now.

On they rushed.

The channel seemed to be so fashioned up to now that they were not compelled to make any choice between rival passages. There had been no such thing as going astray. But shortly afterwards they came to a fork, where a second fissure gaped before them.

Now came the question, which way had the three men gone in order to reach the friendly exit they were acquainted with? Jimmy would have perhaps thrown up a copper cent and trusted to "heads or tails" to settle the matter for him; but this was not the happy-go-lucky way Ned had of deciding.

Of course, it would have been an easy thing for him to have settled in his mind which way the workings of the mine lay. All that was necessary was to look and see which passage showed many marks of loads of ore having been carried along it, portions of which had fallen from the wheel-barrows.

But this would not tell them whether the men had fled by that passage or along the other one. Just then they were bent on chasing after the three miners, and not hunting for the spot from which ore had been taken.

Ned had an idea. These usually came to him like flashes of light, and might almost be called happy inspirations.

He remembered that just after the tremendous crash several of the boys had been half choked by the cloud of dust in the air. He himself had had some difficulty in breathing, and refraining with an effort from coughing. That gave him the thought upon which he hastened to act; and it was here that his Boy Scout training stood him in good stead.

Immediately bending down he held his electric torch to the flat rock that constituted the floor of the passage where it forked, and just as he suspected would be the case, he discovered that a very thin layer of dust had covered the place after the explosion.

While there was not much of this, at the same time, it would allow a pair of keen eyes to discover footprints, providing they had been made after the layer had settled.

Ned's chums watched his every move almost breathlessly. They immediately understood what he expected to do, and while not very sanguine of success, still they hoped for the best.

They saw Ned start to move slowly along. He continued to hold his light close to the rock, and waved it slightly from side to side, as though bent on covering as much ground as possible. But the fact that he did advance showed them that he must be meeting with some success.

Another step did Ned take, then a third and a fourth. The boys began to breathe freely again, for hope had once more taken root in their breasts. They saw that he was showing confidence, as though he had no longer any doubt of his ability to decide the enigma.

Even Jimmy remembered reading about the visit of the Queen of Sheba to the wise Solomon, when he ruled as king, bearing a wreath of natural flowers in one hand and another that was artificial, but so skilfully done that no eye could detect the difference, and then asked him to decide. The wise king had simply ordered a window to be opened, and a lot of bees, searching for honey, soon settled on the right flowers.

That was the commonsense way in which Ned Nestor usually settled knotty problems.

"The trail in the dust runs along the smaller passage, that does not lead to the worked part of the mine," he said; "and so it's up to us to hustle after the three men. So come on boys, and let's hope we get to the open air soon!"
