A TREACHEROUS FOE
"There seems to be fewer twists and turns in this level than on the one below it," Tommy explained, "and I guess we can find our way out readily enough. If we don"t," he went on, "I shall be obliged to eat a ton or two of coal to keep from starving to death."
"Serves you right!" declared Will. "You had no business getting up in the middle of the night and wandering off into the mine!"
"What did you do?" demanded Tommy.
"We waited until morning, and then enlisted the services of the caretaker," replied Will. "So far as I can remember, this is about the nine hundredth relief expedition we"ve been out on in search of you boys!"
"Seems to me," Tommy chuckled, "that you"re the lads that were in need of the relief expedition. We found you boxed up in a chamber in a boat."
"But we wouldn"t have been in any such mess if we hadn"t started out to look you up!" George declared.
"We should have been back before you got out of bed this morning, if some one hadn"t cut our string," replied Sandy. "We had a cinch on getting out, but some geezer led us a fool chase by cutting our cord and steering us around in a circle."
"Did you see any one?" asked Will.
"Not a soul!" was the reply. "But there"s some one in here, just the same. We heard the call of the Wolf Patrol a long time ago and we"ve heard it several times since."
"What do you mean by some one cutting your string?" asked George.
"Why," replied Sandy, "we tied the loose end of a ball of twine to one of the shaft timbers and unwound the ball as we moved along, expecting to follow it back when we wanted to get out.
"How do you know some one cut it?" asked Will.
"Perhaps you broke it," George suggested.
Sandy took a piece of the cord from his pocket and pa.s.sed it over to George with a shy chuckle.
"See if you can break that!" he said.
George tried his best to break the string, but it remained firm under all his strength.
The boys now fell into a discussion of the ways and means of getting out of the mine.
"I believe," Sandy exclaimed, "That if we follow the current of air which the rising water is forcing out of this old shaft, we will come to the entrance. As you all know, a current of air takes the shortest way to any given point, and this one ought to blow straight toward the shaft."
"Great head, that, little boy!" laughed Tommy.
After proceeding some distance the steady thud, thud of the pumping machinery was heard, and the boys understood that the efforts of the caretaker were at last bringing results. The sounds also aided them in direction, and in a short time they stood at the shaft on the second level.
When they came out to the timber work, Will, who was in the lead, motioned to the others to remain in the background.
"What"s doing now?" whispered Sandy.
"There"s a man working on the ladders," explained Will in a low whisper. "I can"t see him yet, but I can hear the sound of a saw."
"He may be cutting the rungs," suggested Tommy.
"That"s the notion I had," replied Will. "Suppose we all get around behind the air shaft and wait until we can find out what he is up to.
It may be that b.u.m detective, for all we know."
"What would he be doing there?" questioned Sandy.
"Sawing the rungs!" whispered Will. "He wouldn"t cut them down, of course, but he might saw them so that they would break under our weight and give us a drop of a couple of hundred feet."
"It doesn"t seem as if any human being would do a thing like that!"
cried George. "It would be a wicked thing to do!"
While the boys whispered together, the sound of sawing continued. The man engaged at the task was evidently unfamiliar with such work, for they heard him puffing and blowing as the saw cut through the wood.
"He"s cutting the rungs, all right!" Will said in a moment. "And that cuts off our escape until the cables can be put in motion and the cages started. I wish I had him by the neck!"
"We"ll get him by the neck, all right, before many days," Sandy cut in, "if we can only get a sight of him so as to be sure of his ident.i.ty."
Presently the man ceased working, and they heard him ascending the ladders, step by step. In a moment the saw which he had been using dropped from his hands and clattered to the bottom of the shaft.
Then they heard him springing swiftly forward, and directly they knew that he had reached the top. The boys all looked disgusted.
"And we never caught sight of him!" exclaimed Tommy.
Will now walked around to the front of the shaft and looked down. The saw which had been used lay shining on the lower level.
"I"m going down after that!" he said in a moment.
"Yes, you are!" whispered Tommy.
"I got to have it!" insisted Will.
"Well, go on and get it, then," laughed Sandy. "You"ve got to show me!"
"I don"t think he cut the rungs between this level and the next one,"
George interposed. "It may be safe to use the lower ladders."
"I can soon find out!" Will declared.
The cutting had been done between the second level and the top. The ladders below seemed perfectly safe. After testing them thoroughly, Will trusted himself on one of the rungs and let himself down slowly, bearing as much weight as was possible on the standards.
He was at the bottom in a moment, and in another moment stood by the side of his chums with the saw in his hand.
"I don"t think that"s so very much!" Tommy exclaimed.
"Right here, then," Will explained, "is where you get your little Sherlock Holmes lesson! This is a new saw, as you all see. It probably never was used before. Now the man who did the cutting bought this at some nearby store. Don"t you see what it means?"
"That"s a fact!" cried Tommy. "We can find out who bought the saw, and so discover the gink who tried to commit murder by sawing the ladders."
"And look here," Will went on, "do you see these threads hanging to the teeth of the saw? Do you see the color?"
