“I knew it,” replied Dick.

“Well?”

Dick looked at him astonished.  “Well, what?” he inquired.

“Shall we give it up?”

“Give it up!” cried the young man.  “Of course not; what you thinking of?”

“There’s the caribou,” suggested Sam, doubtfully; “or maybe Jingoss has more grub than he’s going to need.  It’s a slim chance.”

They still further reduced the ration of pemmican.  The malnutrition began to play them tricks.  It dizzied their brains, swarmed the vastness with hordes of little, dancing black specks like mosquitoes.  In the morning every muscle of their bodies was stiffened to the consistency of rawhide, and the movements necessary to loosen the fibres became an agony hardly to be endured.  Nothing of voluntary consciousness remained, could remain, but the effort of lifting the feet, driving the dogs, following the Trail; but involuntary consciousness lent them strange hallucinations.  They saw figures moving across the snow, but when they steadied their vision, nothing was there.

They began to stumble over nothing; occasionally to fall.  In this was added effort, but more particularly added annoyance.  They had continually to watch their footsteps.  The walking was no longer involuntary, but they had definitely to think of each movement necessary to the step, and this gave them a further reason for preoccupation, for concentration.  Dick’s sullenness returned, more terrible than in the summer.  He went forward with his head down, refusing to take notice of anything.  He walked:  that was to him the whole of existence.

Once reverting analogously to his grievance of that time, he mentioned the girl, saying briefly that soon they must all die, and it was better that she die now.  Perhaps her share of the pemmican would bring them to their quarry.  The idea of return—­not abandoned, but persistently ignored—­thrust into prominence this other,—­to come to close quarters with the man they pursued, to die grappled with him, dragging him down to the same death by which these three perished.  But Sam would have none of it, and Dick easily dropped the subject, relapsing into his grim monomania of pursuit.

In Dick’s case even the hope of coming to grapples was fading.  He somehow had little faith in his enemy.  The man was too intangible, too difficult to gauge.  Dick had not caught a glimpse of the Indian since the pursuit began.  The young man realised perfectly his own exhaustion; but he had no means of knowing whether or not the Indian was tiring.  His faith waned, though his determination did not.  Unconsciously he substituted this monomania of pursuit.  It took the place of the faith he felt slipping from him—­the faith that ever he would see the fata morgana luring him out into the Silent Places.
