The Adventure Of Norah Sullivan And The Student Of Heredity
by
“What is it?”
“That was Ribot.”
“Who and what is Ribot?”
“Ribot was a celebrated French scientist, an authority on the subject of heredity. You doubtless know something of the subject, how certain traits appear in families generation after generation. Accidental traits, if repeated for two or three generations, often become inherent traits. To show you to what a strange extent this is true, I will call your attention to the case of the ducal house of Bethune in France, where three successive generations having had the left hand cut off at the wrist in battle, the next three generations were born without a left hand.”
The erudite dissertation of Wilhelm Klingenspiel was here interrupted by the reappearance of the mottled monster, who, with a scream that filled the blue vault of heaven, rushed into the yard and paused before a mighty oak, whose sturdy trunk had stood rooted in that soil before the city of Chicago existed, before the United States was born, when Cahokia was the capital of Illinois and the flag of France waved over the great West. The flash of terrible white teeth showed in the moonlight as the monster gnawed at the base of the tree a few times and with a crash its leafy length lay upon the ground. Contemplating for a brief space the ruin it had wrought, the monster emitted another of its appalling screams and was off once more on its erratic, aimless course.
“What in the world is this awful creature?” cried Nora.
“The subject of heredity,” resumed Klingenspiel, “is one of vast importance, and although its principles are well understood, man has hitherto not touched the possibilities that can be accomplished. The span of a man’s life is so short that in selecting and breeding choice strains of animals, an individual can see only a comparatively small number of generations succeed each other. Suppose some one family had for two hundred years carried on continuous experiments in breeding any race of animals. What remarkable results would have been attained! Behold what remarkable results are attained in raising varieties of plants, where the swiftness of succeeding generations enables man to accomplish what he seeks in a very short time. Observing the difficulties that confront the animal breeder and wishing to see in my own lifetime certain results that might ordinarily be expected only in a duration of several lifetimes, I sought an animal which came to maturity rapidly, whose generations succeeded each rapidly. At the same time, I wanted an animal comparatively highly organized, a mammal, not a reptile.”
At this point, his instructive discourse was interrupted by the reappearance of the monster, which charged into the yard with its nose to the ground, following some scent, sniffing so loudly that the sound was plainly audible despite the closed window. After having hastened about the yard for a few moments it was off up the road to the eastward, still with nose to the ground, until coming to the push cart left at the roadside by Nora, it examined it carefully and then with a sudden access of unaccountable rage, fell upon it and demolished it, beating and chewing it into bits.
Whatever celerity this terrible beast had exhibited before, was now completely eclipsed, as with nose to the ground, it rushed back to the yard, straight to the house, and rearing on its hinder quarters, placed its forelegs on the porch roof, which gave way beneath the ponderous weight. Not disconcerted by the removal of this support, the monster continued to maintain its sitting posture, looking in the window at the terrified persons beyond, snapping and gnashing its huge jaws in a manner terrible to hear and still more terrible to contemplate. Nora was partially reassured by observing that the animal’s head was too wide to go through the window, but the hopes thus raised were dashed by Klingenspiel moaning:
“He’ll gnaw right through the house, he’ll chew right through the roof. He’ll get in. He has smelled that big cabbage and he’ll get in.”
