Whatever fascination the creature might exercise in his native haunts, Mr. Bernard found himself not in the least nervous or affected in any way while looking at his caged reptiles. When their cage was shaken, they would lift their heads and spring their rattles; but the sound was by no means so formidable to listen to as when it reverberated among the chasms of the echoing rocks. The expression of the creatures was watchful, still, grave, passionless, fate-like, suggesting a cold malignity which seemed to be waiting for its opportunity. Their awful, deep-cut mouths were sternly closed over the long hollow fangs which rested their roots against the swollen poison-gland, where the venom had been hoarding up ever since the last stroke had emptied it. They never winked, for ophidians have no movable eyelids, but kept up that awful fixed stare which made the two unwinking gladiators the survivors of twenty pairs matched by one of the Roman Emperors, as Pliny tells us, in his “Natural History.” Their eyes did not flash, but shone with a cold still light. They were of a pale-golden or straw color, horrible to look into, with their stony calmness, their pitiless indifference, hardly enlivened by the almost imperceptible vertical slit of the pupil, through which Death seemed to be looking out like the archer behind the long narrow loop-hole in a blank turret-wall. On the whole, the caged reptiles, horrid as they were, hardly matched his recollections of what he had seen or dreamed he save at the cavern. These looked dangerous enough, but yet quiet. A treacherous stillness, however,—as the unfortunate New York physician found, when he put his foot out to wake up the torpid creature, and instantly the fang flashed through his boot, carrying the poison into his blood, and death with it.

Mr. Bernard kept these strange creatures, and watched all their habits with a natural curiosity. In any collection of animals the venomous beasts are looked at with the greatest interest, just as the greatest villains are most run after by the unknown public. Nobody troubles himself for a common striped snake or a petty thief, but a cobra or a wife-killer is a centre of attraction to all eyes. These captives did very little to earn their living, but, on the other hand, their living was not expensive, their diet being nothing but air, au naturel. Months and months these creatures will live and seem to thrive well enough, as any showman who has then in his menagerie will testify, though they never touch anything to eat or drink.

In the mean time Mr. Bernard had become very curious about a class of subjects not treated of in any detail in those text-books accessible in most country-towns, to the exclusion of the more special treatises, and especially of the rare and ancient works found on the shelves of the larger city-libraries. He was on a visit to old Dr. Kittredge one day, having been asked by him to call in for a few moments as soon as convenient. The Doctor smiled good-humoredly when he asked him if he had an extensive collection of medical works.

“Why, no,” said the old Doctor, “I haven't got a great many printed books; and what I have I don't read quite as often as I might, I'm afraid. I read and studied in the time of it, when I was in the midst of the young men who were all at work with their books; but it's a mighty hard matter, when you go off alone into the country, to keep up with all that's going on in the Societies and the Colleges. I'll tell you, though, Mr. Langdon, when a man that's once started right lives among sick folks for five-and-thirty years, as I've done, if he has n't got a library of five-and-thirty volumes bound up in his head at the end of that time, he'd better stop driving round and sell his horse and sulky. I know the bigger part of the families within a dozen miles' ride. I know the families that have a way of living through everything, and I know the other set that have the trick of dying without any kind of reason for it. I know the years when the fevers and dysenteries are in earnest, and when they're only making believe. I know the folks that think they're dying as soon as they're sick, and the folks that never find out they 're sick till they're dead. I don't want to undervalue your science, Mr. Langdon. There are things I never learned, because they came in after my day, and I am very glad to send my patients to those that do know them, when I am at fault; but I know these people about here, fathers and mothers, and children and grandchildren, so as all the science in the world can't know them, without it takes time about it, and sees them grow up and grow old, and how the wear and tear of life comes to them. You can't tell a horse by driving him once, Mr. Langdon, nor a patient by talking half an hour with him.”

“Do you know much about the Venner family?” said Mr. Bernard, in a natural way enough, the Doctor's talk having suggested the question.

The Doctor lifted his head with his accustomed movement, so as to command the young man through his spectacles.

“I know all the families of this place and its neighborhood,” he answered.

“We have the young lady studying with us at the Institute,” said Mr. Bernard.

“I know it,” the Doctor answered. “Is she a good scholar?”

All this time the Doctor's eyes were fixed steadily on Mr. Bernard, looking through the glasses.
