Link Ferris, in blank incredulity, stood gaping at the picture before him--staring at the tireless swiftness of his dog in turning back and rounding up a scattered flock which Ferris himself could not have bunched in twenty times the space of minutes. Chum, he noted, did not touch one of the foolish beasts.
His bark and his zigzag dashes served the purpose, without the aid of teeth or of actual contact.
Presently, as the dumbfounded man gazed, the last stray was added to the milling, bleating bunch, and Chum was serenely trotting to and fro, driving back such of the sheep as sought to break loose from the huddle. Terrified and trembling, but mastered, the flock cowered motionless. The work was done.
As in a dream Link tumbled toward the prisoners. His mind functioning subconsciously, he took up his interrupted task of driving them to pasture. The moment he succeeded in getting them into motion they broke again. And again, like a furry whirlwind, Chum was encircling them; chasing the strays into place. He saw, without being told, the course his master was taking, and he drove his charges accordingly.
Thus, in far less time and in better order than ever before, the flock reached the rickety gateway of the stone-strewn sheep pasture and scuttled jostlingly in through it.
Link shut the gate after them. Then, still in a daze, he turned on the dog.
"Chum," he said confusedly, "it don't make sense to me, not even yet. I don't get the hang of it. But I know this much: I know you got ten times the sense what I'VE got. Where you got it an' how you got it the good Lord only knows. But you've got it. I--I was figgerin' on lickin' you 'most to death, a few minutes back.
Chum. Honest, I was. I'm clean 'shamed to look you in the face when I think of it. Say! Do me a favor, Chum. If ever I lift hand to lick you, jes' bite me and give me hydrophoby. For I'll sure be deservin' it. Now come on home!"He patted the silken head of the jubilant dog as he talked, rumpling the soft ears and stroking the long, blazed muzzle. He was sick at heart at memory of his recent murderous rage at this wonder-comrade of his.
Chum was exultantly happy. He had had a most exhilarating ten minutes. The jolliest bit of fun he could remember in all his two years of life. The sight of those queer sheep--yes, and the scent of them, especially the scent--had done queer things to his brain; had aroused a million sleeping ancestral memories.
He had understood perfectly well his master's order that he leave them alone. And he had been disappointed by it. He himself had not known clearly what it was he would have liked to do to them.
But he had known he and they ought to have some sort of relationship. And then at the gesture and the snarled command of "Go get them!" some closed door in Chum's mind had swung wide, and, acting on an instinct he himself did not understand, he had hurled himself into the gay task of rounding up the flock.
So, for a thousand generations on the Scottish hills, had Chum's ancestors earned their right to live. And so through successive generations had they imbued their progeny with that accomplishment until it had become a primal instinct. Even as the unbroken pointer of the best type knows by instinct the rudiments of his work in the field so will many a collie take up sheep herding by ancestral training.
There had been nothing wonderful in Chum's exploit. Hundreds of untrained collies have done the same thing on their first sight of sheep. The craving to chase and slay sheep is a mere perversion of this olden instinct; just as the disorderly "flushing" and scattering of bird coveys is a perversion of the pointer or setter instinct. Chum, luckily for himself and for his master's flock, chanced to run true to form in this matter of heredity, instead of inheriting his tendency in the form of a taste for sheep murder.
The first collie, back in prehistoric days, was the first dog with the wit to know his master's sheep apart from all other sheep. Perhaps that is the best, if least scientific, theory of the collie's origin.
But to Link Ferris's unsophisticated eyes the achievement was all but supernatural, and it doubled his love for the dog.
That afternoon, by way of experiment, Ferris took Chum along when he went to drive the sheep back from pasture to the fold. By the time he and the dog were within a hundred yards of the pasture gate Chum began to dance, from sheer anticipation; mincing sidewise on the tips of his toes in true collie fashion, and varying the dance by little rushes forward.
Link opened the crazy gate. Waiting for no further encouragement the dog sped into the broad field and among the grazing sheep that were distributed unevenly over the entire area of the lot.
Ordinarily--unless the sheep were ready to come home--it was a matter of ten or fifteen minutes each evening for Link to collect them and start them on their way. To-day, in less than three minutes, Chum had the whole flock herded and trotting through the opening, to the lane outside.
Nor, this time, did the sheep flee from him in the same panic dread as in the morning. They seemed to have learned--if indeed a sheep can ever learn anything--that Chum was their driver, not their enemy.
From the fold Link as usual went to the woodlot where his five head of lean milch cattle were at graze. Three of the cows were waiting at the bars for him, but one heifer and a new-dry Holstein were hidden somewhere in the recesses of the second-growth timber.
The afternoon was hot; it had been a hot day. Link was tired. He dreaded the labor of exploring ten acres of undergrowth for his two missing cattle. An inspiration came to him. Pointing to the three stolidly waiting cows at the bars he waved his arm in the general direction of the lot and called on Chum.
"Go find 'em! Bring 'em in!"
