There was no answering shot, and he leaped forward, charging directly toward the tree that concealed the hidden foe before the man could reload; for by the roar of its discharge, MacNair knew that the weapon was an old Hudson Bay muzzle-loading smoothbore--a primitive weapon of the old North, but in the hands of an Indian, a weapon of terrible execution at short range, where a roughly moulded bullet or a slug rudely hammered from the solder melted from old tin cans tears its way through the flesh, driven by three fingers of black powder.
Near the tree MacNair found the gun where its owner had hurled it into the snow--found also the tracks of a pair of snowshoes, which headed into the heart of the black spruce swamp. The tracks showed at a glance that the lurking assassin was an Indian, that he was travelling light, and that the chance of running him down was extremely remote. Whereupon MacNair returned his automatic to its holster and bethought himself of Ripley, who was lying back by the stockade with his face buried in the snow.
Swiftly he retraced his steps, and, kneeling beside the wounded man, raised him from the snow. Blood oozed from the corners of the officer's lips, and, mingling with the snow, formed a red slush which clung to the boyish cheek. With his knife MacNair cut through the clothing and disclosed an ugly hole below the right shoulder-blade. He bound up the wound, plugging the hole with suet chewed from a lump which he carried in his pocket. Leaving Ripley upon his face to prevent strangulation from the blood in his throat, he hastened to the camp on the shore of the lake, harnessed the dogs, and returned to the prostrate man; it was the work of a few moments to bind him securely upon the sled. Skilfully MacNair guided his dogs through the maze of the black spruce swamp, and, throwing caution to the winds, crossed the lake, struck into the timber, and headed straight for Chloe Elliston's school.
In the living-room of the little cottage on the Yellow Knife, Harriet Penny and Mary, the Louchoux girl, sat sewing, while Chloe Elliston, with chair pulled close to the table, read by the light of an oil-lamp from a year-old magazine. If the Louchoux girl failed to follow the intricacies of the plot, an observer would scarcely have known it. Nor would he have guessed that less than two short months before this girl had been a skin-clad native of the North who had mushed for thirty days unattended through the heart of the barren grounds. So marvellously had the girl improved and so desirously had she applied her needle, that save for the beaded moccasins upon her feet, her clothing differed in no essential detail from that of Chloe Elliston or of Harriet Penny.
