On into the night sped the automobile, at as fast a pace as Colt dared to drive it along that bumpy twisting road, at the coulée-edge. Chang slumped, half-senseless, into a wayside clump of manzanita.
Colt had taken no foolish chances when he gave the Chinaman a fist-punch instead of the promised forty dollars. He was thrifty, was Fraser Colt. He was averse to unnecessary expense. He knew Chang would not dare betray him to Fenno or to Royce; and thus confess his own share in the kidnaping. With a smile of pure happiness, he drove on, not troubling to look back at his dupe.
Now, Treve was anything but a fool. When frantic struggles availed only to enmesh him the tighter and to exhaust what little air could still seep into the close-woven canvas sack—when his growls of wrath were smothered in the almost sound-proof bag—he sought the next expedient for escape.
By the time he had reached the gate, on Chang’s shoulders, the dog had rid his mouth of the stuffed folds of cloth which had been thrust therein as a gag. The first use he made of this freedom of teeth was to seize the nearest fold of canvas between his scissors-sharp incisors; and begin to gnaw.
Any one who has watched a mischievous puppy gnaw holes in a mat can imagine the power exerted by the skilled and mighty jaws of a grown collie; if put to such infantile use. By the time he was flung into the tonneau, Treve had worked a hole in the canvas, wide enough to permit his protruding nose to escape.
Wasting no time in vain howls, he wrought furiously and deftly on such portions of bag and rope as seemed to bind him most tightly. When it came to severing the twined rope, he resorted again to gnawing tactics. But with the rest of the bag, his curved tusks as well were brought into play.
Twice he heaved himself upright, only to find some part of him was still fast to the bag. Both times, he whirled about and bit fiercely into the trammeling folds or rope. He worked now with added zest of fury. For his nostrils had caught the hated scent of Fraser Colt, the man he detested above all the world. The man who had maltreated him and had fought with Joel Fenno,—the only unfriendly human the dog had known! And he saw and smelt that his mortal enemy was in the seat just in front of him.
Too wise to risk attack until he should be free, he continued to rend loose his bonds. The car was jolting and bumping and rattling at first speed over the bad bit of climb in the trail-like road; rendering its driver deaf to the muffled sounds behind him.
Then, as Colt bent forward over the wheel, to negotiate a particularly tricky twist of the climbing road, something silent and terrible launched itself upon him from behind.
Sixty-odd pounds of furry muscular weight crashed against his fat shoulders. A double set of razor-teeth sheared like red-hot iron into the back of his fat neck.
