don't see why I shouldn't tell you what brings us here. My mother owns a tract of timber land a little further around the mountain, and it is pretty much all she does own in the world. She's a widow, and she's had a pretty hard time to bring up three boys of us"—turning and indicating his two brothers—"and now we see a way of helping her. They're going to build a railroad down in the valley on the other side of this mountain, and they want railroad ties. So we have organized a party and come up here to chop down trees, make ties and send them down the mountain by a chute."

"Um," answered the mountaineer. "What's them there things for?" pointing to the Doctor's scientific instruments hanging about on the trees.

"They are scientific instruments, if you know what that means," answered Jack, who was beginning to grow irritable under the intruder's impertinent questioning.

"What are you goin' to do with 'em? Will they help you to chop wood?"

"No, of course not. But the Doctor here," indicating him, "is much interested in science and he has brought his instruments along so as to make our stay on the mountains as profitable as possible in the way of study."

"My friend," broke in the Doctor, addressing the mountaineer, "If you will come to our camp when we get settled I'll show you how I use these things and what they tell me. One of them tells me how high up we are and when it's going to storm or clear away; another shows how fast the wind is blowing, another how cold it is and so on."

"Which one on 'em tells the strength of whiskey and how much tax they ought to be paid on it?"

This question was asked with a peculiar tone of sneering incredulity and suspicion.

"Not one of them has any relation whatever to whiskey or taxes or anything of the sort," answered the Doctor.

By this time Jack's patience was exhausted and by common consent Jack was the leader of the party. He turned to the tree behind him, seized his shot gun, presented it at the mountaineer's breast before that worthy could bring his rifle to his shoulder, and in an angry, but still cold voice, said:

"I'll trouble you to lay down that rifle."

The man obeyed.

"Now I'll trouble you, if you please to lay down your powder horn and your bullet pouch and your cap box and everything else that pertains to that rifle." All this while Jack was holding the muzzle of his full-cocked, double barrelled shot gun in front of the man's breast, while all the other boys had seized their guns and stood ready for action. The Doctor had not a shot gun, but a repeating, magazine rifle of the latest make, long in its range, exceedingly accurate in its fire and equipped with fourteen cartridges in its magazine that could be fired as fast as their owner pleased. And the moment that the mountaineer, before he laid down his rifle, made a motion as if to bring it to his shoulder, the Doctor had stepped to Jack's side with his destructive weapon in position for instant use. After the man had laid down his arms, the Doctor stepped back, lowered his weapon and said to Jack:—"Manage the affair in your own way. Only be prudent, and above all don't lose your temper."

Jack then said to the mountaineer:

"You've asked us a number of questions. Now I want to ask you some. What do you mean by intruding upon our camp? Who are you? What right have you to ask us about ourselves and our mission in these mountains? Answer man, and answer quick or I'll put two charges of buck shot through you in less than half a minute."

"Now, don't be too hard on a feller, pard," answered the man. "I didn't mean no harm in partic'lar. But you see us fellers that lives up here in the high mountings has a hard enough time to git a livin' and we don't like to be interfered with by no revenue officers and no spies and no speculators from down below. You see if we're caught, some of the money goes to the informer, an' so we takes good keer to have no informers about, an' if they insist on stayin' we usually buries 'em. Now you've got the drap on me an' my only chance is to go way if you'll let me go. So far as I'm concerned you're welcome to go round the mounting an' chop all the railroad ties an' cordwood you choose. But there's fellers in the mountings that you ain't got no drap on, as you've got it on me, an' fellers what ain't so tender hearted as me. An' so, while I'll leave my gun an' promise never to meddle with you again if you won't shoot, at the same time my earnest, friendly, fatherly advice to you boys is to take yourselves down out'n this mounting jes' as quick as you kin. It ain't no place for people of your sort."

"We'll do nothing of the kind," answered Jack. "We've come up here on a perfectly honest and legitimate mission, and we're going to carry it out. We are not interfering with anybody and I give you warning that if anybody interferes with us it will be the worse for him. We are armed, every man of us and we are prepared to use our arms. Tom,"—turning to his brother,—"take that man's rifle and discharge it into the cliff back there."

Tom obeyed the command instantly. Then Jack said to their unwelcome visitor, "Now you can take your rifle and go away. But don't intrude upon us again. If you do, you'll get the contents of our guns without any explanations or any arguments. Take your gun and go!"

The intruder took his gun and accoutrements and without a word walked away up the mountain through the timber land.

"What does it all mean, Jack?" asked all the boys at once.

"Moonshiners," broke in Tom, sententiously.

Moonshiners are men who operate little unlicensed distilleries in the fastnesses of the mountains and surreptitiously sell their whiskey without paying the government tax upon it.

"But why should moonshiners object to our camping in the wood lands up here and cutting railroad ties?" asked Jim Chenowith. "I don't see the connection."

"Well, they do," answered Tom. "They are engaged in a criminal business and they don't want to be watched. If they are caught their stills and their whiskey are confiscated, they are fined heavily, and worse still they are imprisoned for very long terms. They are always on the lookout for agents of the revenue in disguise, and so they don't want any strangers in this 'land of the sky' on any pretence. They are desperate men to whom murder is a pastime and assassination an amusement."

"Then why did you anger the man as you did, Jack, and subject him to humiliation?" asked Ed Parmly. "Won't it make him and his people our enemies?"

"No," answered Jack. "They are that already. You remember that even after hearing my explanation of our purpose in coming up here, he ordered us to leave the mountain at once. Not being a pack of cowards of course we're not going to do anything of the kind. So it was just as well to let him know at once that we're going to stay, that we are fully armed, and that in the event of necessity we shall be what he would call 'quick on trigger.' I meant him to understand that clearly, and he understands it. You see men that are freest in killing other men have no more fondness than people generally for being killed themselves. Desperadoes are not heroes. They are merely bullies who take advantage of an unarmed enemy when they can and sneak away as that man did whenever an enemy 'gits the drap' on them as the fellow phrased it."

"But won't they attack us in our camp?" asked Jim Chenowith.

"Probably," answered Jack with perfect calmness. "They want us out of the mountains and they'll probably try to drive us out. But I for one am not going to be driven out, and I don't think the rest of you fellows are Molly Cottontails to be chased down the steeps."

"No!" called out little Tom. "We've got guns and we know how to use them. We're up here by right and here we'll stay. Won't we boys?"

"Yes! Yes! Yes!" answered the others in chorus.

"All right then," said Jack, "and I thank you all. But now that we know our danger we must look out for ourselves. We must never sleep
