This time his teeth flashed quicker and with deeper intent at the jowl-clutching hand, and, missing, he was seized and flung down the smooth incline harder and farther than before.  He was growing angry, as he clawed back, though he was not conscious of it.  But the mate, being a man, albeit a drunken one, sensed the change in Jerry’s attack ere Jerry dreamed there was any change in it.  And not only did Borckman sense it, but it served as a spur to drive him back into primitive beastliness, and to fight to master this puppy as a primitive man, under dissimilar provocation, might have fought with the members of the first litter stolen from a wolf-den among the rocks.

True, Jerry could trace as far back.  His ancient ancestors had been Irish wolf-hounds, and, long before that, the ancestors of the wolf-hounds had been wolves.  The note in Jerry’s growls changed.  The unforgotten and ineffaceable past strummed the fibres of his throat.  His teeth flashed with fierce intent, in the desire of sinking as deep in the man’s hand as passion could drive.  For Jerry by this time was all passion.  He had leaped back into the dark stark rawness of the early world almost as swiftly as had Borckman.  And this time his teeth scored, ripping the tender and sensitive and flesh of all the inside of the first and second joints of Borckman’s right hand.  Jerry’s teeth were needles that stung, and Borckman, gaining the grasp on Jerry’s jaw, flung him away and down so that almost he hit the Arangi’s tiny-rail ere his clawing feet stopped him.

And Van Horn, having finished his rearrangement and repair of the explosive-filled drawer under the mate’s bunk, climbed up the companion steps, saw the battle, paused, and quietly looked on.

But he looked across a million years, at two mad creatures who had slipped the leach of the generations and who were back in the darkness of spawning life ere dawning intelligence had modified the chemistry of such life to softness of consideration.  What stirred in the brain crypts of Borckman’s heredity, stirred in the brain-crypts of Jerry’s heredity.  Time had gone backward for both.  All the endeavour and achievement of the ten thousand generations was not, and, as wolf-dog and wild-man, the combat was between Jerry and the mate.  Neither saw Van Horn, who was inside the companionway hatch, his eyes level with the combing.

To Jerry, Borckman was now no more a god than was he himself a mere, smooth-coated Irish terrier.  Both had forgotten the million years stamped into their heredity more feebly, less eraseably, than what had been stamped in prior to the million years.  Jerry did not know drunkenness, but he did know unfairness; and it was with raging indignation that he knew it.  Borckman fumbled his next counter to Jerry’s attack, missed, and had both hands slashed in quick succession ere he managed to send the puppy sliding.

And still Jerry came back.  As any screaming creature of the jungle, he hysterically squalled his indignation.  But he made no whimper.  Nor did he wince or cringe to the blows.  He bored straight in, striving, without avoiding a blow, to beat and meet the blow with his teeth.  So hard was he flung down the last time that his side smashed painfully against the rail, and Van Horn cried out:
