Treachery in the Air.  
At this time the half-breeds of the colony of Red River formed a small party compared with the numbers to which they multiplied in after years, and the band of hunters who annually went to the plains to chase the buffalo was proportionally small. Nevertheless, they were numerous enough to constitute a formidable band, capable of holding their own, when united, against any band of wandering Indians who might feel disposed to attack them. They were a brave, hardy race of men, but of course there were some black sheep among them like La Certe.
 
About sixty or a hundred miles from the Settlement, the party, under command of Antoine Dechamp, found the buffalo, and preparations were at once made to attack them. It was dusk, however, when the herds were discovered, so that the hunt had to be postponed to the following day.
 
A small clump of bushes afforded wood enough for camp-fires. The carts were ranged in a circle with the trains outward. Sentries were posted; the horses were secured; the kettles put on; pipes lighted; and noise, laughter, song and story, mingled with the shrill voices of children, were heard far on into the night.
 
Among the children, if we may venture so to class them, were Archie and Billie Sinclair—though we suspect that Archie would have claimed, and with some reason, to be classed with the men. They belonged to the camp-fire, which formed a centre to the party composed of Dan and Peter, Fergus, Dechamp, and Fred Jenkins the sailor. The latter, who it was thought had come out to the country by way of a skylark rather than as a settler, had followed the hunters, bent, he said, on firing a broadside into a buffalo. He had brought with him a blunderbuss, which he averred had been used by his great-grandfather at the battle of Culloden. It was a formidable old weapon, capable of swallowing, at one gulp, several of the bullets which fitted the trading guns of the country. Its powers of scattering ordinary shot in large quantity had proved to be very effective, and had done such execution among flocks of wild-fowl, that the Indians and half-breeds, although at first inclined to laugh at it, were ultimately filled with respect.
 
“I doubt its capacity for sending ball straight, however,” remarked Dan to Jenkins, who was carefully cleaning out the piece, “especially if charged with more than one ball.”
 
“No fear of it,” returned the sailor, with a confident air. “Of course it scattered the balls about six yards apart the only time I tried it with a lot of ’em, but that was at fifty yards off, an’ they tell me that you a’most ram the muzzle against the brutes’ sides when chasin’ buffalo. So there’s no room to scatter, d’ee see, till they get inside their bodies, and when there it don’t matter how much they scatter.”
 
“It’s well named a young cannon by La Certe,” said Peter Davidson, who, like the seaman, was out on his first buffalo-hunt. “I never heard such a roar as it gave that time you brought down ten out of one flock of ducks on the way up here.”
 
“Ay, Peter, she barked well that time,” remarked the sailor, with a grin, “but, then there was a reason. I had double-shotted her by mistake.”
 
“An’ ye did it too without an aim, for you had both eyes tight shut at the time,” remarked Fergus. “Iss that the way they teach ye to shoot at sea?”
 
“In course it is,” replied Jenkins, gravely. “That’s the beauty o’ the blunderbuss. There’s no chance o’ missin’, so what ’ud be the use o’ keepin’ yer eyes open, excep’ to get ’em filled wi’ smoke. You’ve on’y got to point straight, an’ blaze away.”
 
“I did not know that you use the blunderbuss in your ships at all,” said Dechamp, with a look of assumed simplicity.
 
“Ho yes, they do,” said Jenkins, squinting down the bell-mouthed barrel, as if to see that the touch-hole was clear. “Aboard o’ one man-o’-war that I sailed in after pirates in the China seas, we had a blunderbuss company. The first-leftenant, who was thought to be queer in his head, he got it up.
 
“The first time the company was ranged along the deck he gave the order to load with ball cartridges. There was twenty-six of us, all told.
 
“‘We’ve got no cartridges for ’em, sir,’ whispered the man nearest him.
 
“‘If you don’t obey orders,’ growled the leftenant ’tween his teeth, ‘I’ll have ye strung up for mutiny every man Jack of you—load!’ he repeated in a kind of a yell.
 
“We had our or’nary belts and pouches on, so we out wi’ the or’nary cartridges—some three, some four,—an’, biting off the ends, poured in the powder somehow, shoved in the balls anyhow, an’ rammed the whole consarn down.
 
“‘Present—fire!’ roared the leftenant.
 
“Bang! went the six an’ twenty blunderbusses, an’ when the smoke cleared away there was fourteen out o’ the twenty-six men flat on their backs. The rest o’ us was raither stunned, but hearty.
 
“‘Take these men below,’ cried the leftenant, ‘an’ send fourteen strong men here. We don’t want weaklings for this company.’
 
“After that we loaded in moderation, an’ got on better.”
 
“And the pirates—what did they think o’ the new weapon?” asked Peter Davidson, with an amused expression.
 
“O! they couldn’t stand it at all,” answered the sailor, looking up from his work, with a solemnity that was quite impressive. “They stood fire only once. After that they sheered off like wild-cats. I say, Mistress La Certe, how long is that lobscouse—or whatever you call it,—goin’ to be in cookin’?” Slowfoot gave vent to a sweet, low giggle, as she lifted the kettle off the hook, and thus gave a practical answer to the question. She placed before him the robbiboo, or pemmican, soup, which the seaman had so grievously misnamed.
 
During the time that the hunters were appeasing their appetites, it was observed that Antoine Dechamp, the leader of the expedition, was unusually silent and thoughtful, and that he betrayed a slight look of anxiety. It therefore did not surprise Dan Davidson, when the supper was nearly ended, that Dechamp should rise and leave the fire after giving him a look which was a silent but obvious invitation to follow.
 
Dan obeyed at once, and his leader, conducting him between the various camp-fires, led him outside the circle of carts.
 
A clear moon lit up the prairie all round, so that they could see its undulating sweep in every direction.
 
“Anything wrong, Antoine?” asked Dan in a low voice, when they were out of earshot of the camp.
 
“Nothing wrong, Dan.”
 
“Surely,” continued the other, while Dechamp paused as if in perplexity, “surely there can be no chance of Red-skins troubling us on a clear night like this. I can distinguish every bush for miles around.”
 
“There is no fear o’ Red-skins. No, I am not troubled about them. It is matters concerning yourself that trouble me.”
 
“How’s that? What do you mean, Antoine?”
 
“Is your brother-in-law-to-be, Duncan McKay, coming to join us this spring?” asked Dechamp.
 
“I believe he is—after he has helped his father a bit longer wi’ the farm. Why do you ask?”
 
“Well, to say truth, I can’t give you a very good reason for my bein’ anxious. Only I can’t help havin’ my ears open, and I’ve heard some talk among the lads that makes me fear for the young man. They say, or hint, that he knows more about the murder o’ poor Perrin than he chooses to tell. I’ve not been quite able to find out what makes them suspect him, but they do suspect him, an’ it would be well to warn him not to come here, for you know there are many opportunities to commit murder on a buffalo-hunt!”
 
The incident of the knife, and of Duncan McKay’s significant glance, at once flashed across Davidson’s mind, and he felt a terrible sinking of the heart when the suspicion, once before roused within him, seemed now to be confirmed. He resolved, however, to reveal his thoughts to no one—specially not to Elspie.
 
“I think it a shame,” he said, “that men should allow such rumours to circulate, when nothing certain has arisen to rouse suspicion. That affair of the knife was clearly explained when young McKay declared that it was not his, though it looked like it. If he knew anything about the murder, would he not have been certain to have told us long ago? And, surely, you cannot suppose that Duncan killed Perrin with his own hand? Speak, Dechamp! Why do you shake your head?”
 
“I know nothing,” returned the leader. “What right have I to suppose anything? I only know that men’s deeds are often mysterious and unaccountable, and that our men have strong suspicion. For myself, I have no opinion. Duncan McKay is probably innocent, for he and Perrin were not enemies. I hope he is so, but I advise you to stop his coming to the camp just now if you can. His life may depend on it.”
 
“I cannot stop him,” returned Dan, with a perplexed look. “He is headstrong, as you know, and if he has made up his mind to come, nothing will stop him.”
 
“Perhaps if he knew his life would be in danger—that might stop him.”
 
“I doubt it; but I will give him the chance. I will ride back to Red River without delay, and warn him.”
 
“Good. When will you start?”
 
“To-night. The moon is clear and will not set till morning. I shall be well on my way by that time.”
 
“Will you ride alone?”
 
“No, there may be bad Indians about. I will ask Okématan or Fergus McKay to ride with me. Why did you not speak to Fergus instead of to me?”
 
“Because he has not been spoken to by any one,” answered Dechamp; “and I would not be the first to put suspicion into his head about his own brother. Besides, your head is clearer; and your interest in Duncan, for Elspie’s sake, is greater than his, no doubt.”
 
“Well, you may be right, Antoine. At all events if I take Fergus with me I shall send him back before reaching the Settlement, and say nothing whatever about my reason for going there. ‘Pressing business,’ you know, will be sufficient.”
 
“I’m not so sure of that,” returned Dechamp with a laugh. “Men are apt to want to know the nature of ‘pressing business.’ However, it may be as well to take Fergus. At any rate you cannot have Okématan, for he is not in camp, he left soon............
