hookey, I do! It’s – it’s – ”
“A man!”
“Holy smoke! What’ll we do now?”
“Get after him, of course. Come on!”
Clutching his rifle in his gloved hands Tom started forward, but before he could move another step he stopped short. From over by the black fox’s cage there came a shot and a blinding flash.
“He’s shooting!” cried Sandy in real alarm.
“Yes, but not at us,” rejoined Tom excitedly, springing forward once more, “it’s the black fox he is after. We’ve got to head him off in that little game.”
CHAPTER IV – THE TRACKS IN THE SNOW
As they ran across the bridge of planks connecting the Yukon Rover with the shore, the boys saw something else. Standing by the cages in such a position that they had not seen it before was a dog-sled.
Even as they were still on the gangway the form of a man glided through the darkness toward the sled. In his arms he held a bundle of some sort.
“Stop where you are!” cried Tom, guessing with a catch at the heart what it was the man was carrying.
There was no reply. The man had reached the sled and bent swiftly over it an instant.
Crack!
Jack gave a jump. The man was not shooting. It was the sharp crack of his dog-whip, sounding like the report of a pistol on the frozen air, that had startled the boy.
The dogs started forward. The sled creaked on the hard, packed snow. It began to glide off through the night like a phantom.
“Stop or we’ll fire!” shouted Jack excitedly.
He raised his rifle but Tom sternly grasped his arm.
“None of that,” ordered the elder Dacre boy sternly.
“But – but he’s a robber, or at least attempted to be one,” sputtered Jack indignantly.
“That makes no difference. We don’t want any shooting.”
“Hoosh!” exclaimed Sandy disgustedly, “you’re going to let him get clear away.”
Before Tom could check him, the Scotch boy had leveled his rifle and fired in the direction of the sled, which could now only be made out as a dark object gliding swiftly off over the snow.
From that direction there floated back to them a laugh. It was a derisive sound that made Tom’s blood boil, but he kept his head.
“You do anything like that again, Sandy,” he said, turning on the Scotch lad, “and you’ll have me to settle with.”
“But we can’t let him get away like that without raising a finger, – hoosh!” exclaimed Sandy indignantly.
“Let’s first see if he has really done any harm,” said Tom, “he may have only intended it and we have frightened him off.”
But although he spoke hopefully, Tom’s inner senses told him that the daring marauder had done more than merely alarm them. In the first place, there was the shot coming from the direction of the black fox’s cage. To Tom that could mean only one thing and that was that the intruder had killed the occupant of the cage. In fact, that was the only way that he could have secured his prey, for the foxes were wild and savage to a degree, and it would have been impossible for anyone to abstract them alive.
All these thoughts and conclusions flitted through his mind while Jack and Sandy, at his orders, were getting a lantern. When it arrived, the three boys in any but enviable frames of mind made their way as quickly as possible to the fox cages.
The animals were excited and frightened, and through the darkness their anxious eyes glowed like jewels as the lantern light struck them. This showed Tom that at least six of the cages still held their occupants. But the seventh, the one that had been used to hold the black fox, was apparently empty.
When they reached the pen in question even Tom could not refrain from exclamations of anger, for the cage had been ripped open and the black fox was indeed gone.
On the snow were blood-stains in plenty, and enough mute evidence of the slaying and theft to enable them to reconstruct everything that had happened as well as if they had seen it all.
“Oh! wow! Fifteen hundred dollars gone ker-plunk!” wailed Jack.
“Hoots-toots,” clucked Sandy, clicking his tongue indignantly, “the bonny black fox killed and taken by that gloomerin’ thief!”
Tom alone was silent. The suddenness and completeness of the catastrophe had overwhelmed him. What could they say to Mr. Dacre and his partner when they returned from the settlement? What explanation could they make that would excuse their seeming carelessness?
As Tom stood there beside the empty cage with the blood-stained snow at his feet, he passed through some of the bitterest moments of his life. He was fairly at a standstill. In the dark it would be impossible to overtake the bold thief, and there was no means, of course, of sending out a warning as might have been done in a civilized region.
No; the thief had vanished and there appeared to be not the remotest chance of ever catching him. Any trader would be glad to buy the black fox skin, and with the proceeds the marauder could easily leave the country, leaving no trace behind him.
“What will Uncle Dacre say?”
It was Jack who voiced Tom’s gloomy thoughts. With his younger brother’s words a sudden resolution came into Tom’s mind. Undoubtedly he, as the one in charge of the camp, was responsible for the loss of the black fox. It would never be seen alive again, of that he was sure.
But its skin? That was valuable. If he could only recover that, it would at least be partial restoration for what he, perhaps unjustly, felt was a neglect of his duty.
He came out of his reverie. Swiftly he set about examining the remainder of the cages. They had not been tampered with. No doubt the thief knew that he was not likely to have time to rob more than one cage undisturbed after the noise of his gun had aroused those who were undoubtedly on watch. With this in mind he had taken the most valuable of the lot.
Tom’s eyes fell on the tracks of the dog-sled on the hardly frozen snow. They lay there in the yellow lantern light as clean cut and conspicuous almost as parallel lines of a railroad.
The boy knew that the sled must be packed heavily, probably with all the paraphernalia of a traveling trapper. The question of how the man had come to find out about the valuable collection of foxes on the bank of the Porcupine River, Tom, of course, could not guess. But one thing he did know – that the thief had left behind him a valuable trail which it would be as easy to follow as the red line on a map indicating a transcontinental railroad.
And that track Tom meant to follow before it grew cold. They had no dog sleds, but they knew that the man with his heavy load could not make very fast time. Before daylight, long before the first glimmerings of the brief winter’s day of the north, the boys’ arrangements had been completed.
Snow-shoes were looked over and thongs inspected, tea and provisions packed into provision bags secured with “tump-lines,” and everything put
