on the foundation of other men's labours. No; pari passu with Solander, who bought his knowledge with pain and privations!”
“Have you discovered a mine, Doctor Bat?”
“More than a mine; a treasure coined, and fit for instant use, girl.—Listen! I was making the angle necessary to intersect the line of your uncle's march, after my fruitless search, when I heard sounds like the explosion produced by fire arms—”
“Yes,” exclaimed Ellen, eagerly, “we had an alarm—”
“And thought I was lost,” continued the man of science too much bent on his own ideas, to understand her interruption. “Little danger of that! I made my own base, knew the length of the perpendicular by calculation, and to draw the hypothenuse had nothing to do but to work my angle. I supposed the guns were fired for my benefit, and changed my course for the sounds—not that I think the sense more accurate, or even as accurate as a mathematical calculation, but I feared that some of the children might need my services.”
“They are all happily—”
“Listen,” interrupted the other, already forgetting his affected anxiety for his patients, in the greater importance of the present subject. “I had crossed a large tract of prairie—for sound is conveyed far where there is little obstruction—when I heard the trampling of feet, as if bisons were beating the earth. Then I caught a distant view of a herd of quadrupeds, rushing up and down the swells—animals, which would have still remained unknown and undescribed, had it not been for a most felicitous accident! One, and he a noble specimen of the whole! was running a little apart from the rest. The herd made an inclination in my direction, in which the solitary animal coincided, and this brought him within fifty yards of the spot where I stood. I profited by the opportunity, and by the aid of steel and taper, I wrote his description on the spot. I would have given a thousand dollars, Ellen, for a single shot from the rifle of one of the boys!”
“You carry a pistol, Doctor, why didn't you use it?” said the half inattentive girl, anxiously examining the prairie, but still lingering where she stood, quite willing to be detained.
“Ay, but it carries nothing but the most minute particles of lead, adapted to the destruction of the larger insects and reptiles. No, I did better than to attempt waging a war, in which I could not be the victor. I recorded the event; noting each particular with the precision necessary to science. You shall hear, Ellen; for you are a good and improving girl, and by retaining what you learn in this way, may yet be of great service to learning, should any accident occur to me. Indeed, my worthy Ellen, mine is a pursuit, which has its dangers as well as that of the warrior. This very night,” he continued, glancing his eye behind him, “this awful night, has the principle of life, itself, been in great danger of extinction!”
“By what?”
“By the monster I have discovered. It approached me often, and ever as I receded, it continued to advance. I believe nothing but the little lamp, I carried, was my protector. I kept it between us, whilst I wrote, making it serve the double purpose of luminary and shield. But you shall hear the character of the beast, and you may then judge of the risks we promoters of science run in behalf of mankind.”
The naturalist raised his tablets to the heavens, and disposed himself to read as well as he could, by the dim light they yet shed upon the plain; premising with saying—
“Listen, girl, and you shall hear, with what a treasure it has been my happy lot to enrich the pages of natural history!”
“Is it then a creature of your forming?” said Ellen, turning away from her fruitless examination, with a sudden lighting of her sprightly blue eyes, that showed she knew how to play with the foible of her learned companion.
“Is the power to give life to inanimate matter the gift of man? I would it were! You should speedily see a Historia Naturalis Americana, that would put the sneering imitators of the Frenchman, De Buffon, to shame! A great improvement might be made in the formation of all quadrupeds; especially those in which velocity is a virtue. Two of the inferior limbs should be on the principle of the lever; wheels, perhaps, as they are now formed; though I have not yet determined whether the improvement might be better applied to the anterior or posterior members, inasmuch as I am yet to learn whether dragging or shoving requires the greatest muscular exertion. A natural exudation of the animal might assist in overcoming the friction, and a powerful momentum be obtained. But all this is hopeless—at least for the present!”—he added, raising his tablets again to the light, and reading aloud; “Oct. 6, 1805. that's merely the date, which I dare say you know better than I—mem. Quadruped; seen by star-light, and by the aid of a pocket-lamp, in the prairies of North America—see Journal for Latitude and Meridian. Genus—unknown; therefore named after the discoverer, and from the happy coincidence of being seen in the evening—Vespertilio Horribilis, Americanus. Dimensions (by estimation)—Greatest length, eleven feet; height, six feet; head, erect; nostrils, expansive; eyes, expressive and fierce; teeth, serrated and abundant; tail, horizontal, waving, and slightly feline; feet, large and hairy; talons, long, curvated, dangerous; ears, inconspicuous; horns, elongated, diverging, and formidable; colour, plumbeous-ashy, with fiery spots; voice, sonorous, martial, and appalling; habits, gregarious, carnivorous, fierce, and fearless. There,” exclaimed Obed, when he had ended this sententious but comprehensive description, “there is an animal, which will be likely to dispute with the lion his title to be called the king of the beasts!”
“I know not the meaning of all you have said, Doctor Battius,” returned the quick-witted girl, who understood the weakness of the philosopher, and often indulged him with a title he loved so well to hear; “but I shall think it dangerous to venture far from the camp, if such monsters are prowling over the prairies.”
“You may well call it prowling,” returned the naturalist, nestling still closer to her side, and dropping his voice to such low and undignified tones of confidence, as conveyed a meaning still more pointed than he had intended. “I have never before experienced such a trial of the nervous system; there was a moment, I acknowledge, when the fortiter in re faltered before so terrible an enemy; but the love of natural science bore me up, and brought me off in triumph!”
“You speak a language so different from that we use in Tennessee,” said Ellen, struggling to conceal her laughter, “that I hardly know whether I understand your meaning. If I am right, you wish to say you were chicken-hearted.”
“An absurd simile drawn from an ignorance of the formation of the biped. The heart of a chicken has a just proportion to its other organs, and the domestic fowl is, in a state of nature, a gallant bird. Ellen,” he added, with a countenance so solemn as to produce an impression on the attentive girl, “I was pursued, hunted, and in a danger that I scorn to dwell on—what's that?”
Ellen started; for the earnestness and simple sincerity of her companion's manner had produced a certain degree of credulity, even on her buoyant mind. Looking in the direction indicated by the Doctor, she beheld, in fact, a beast coursing over the prairie, and making a straight and rapid approach to the very spot they occupied. The day was not yet sufficiently advanced to enable her to distinguish its form and character, though enough was discernible to induce her to imagine it a fierce and savage animal.
“It comes! it comes!” exclaimed the Doctor, fumbling, by a sort of instinct, for his tablets, while he fairly tottered on his feet under the powerful efforts he made to maintain his ground. “Now, Ellen, has fortune given me an opportunity to correct the errors made by star-light—hold—ashy-plumbeous—no ears—horns, excessive.” His voice and hand were both arrested by a roar, or rather a shriek from the beast, that was sufficiently terrific to appal even a stouter heart than that of the naturalist. The cries of the animal passed over the prairie in strange cadences, and then succeeded a deep and solemn silence, that was only broken by an uncontrolled fit of merriment from the more musical voice of Ellen Wade. In the mean time the naturalist stood like a statue of amazement, permitting a well-grown ass, against whose approach he no longer offered his boasted shield of light, to smell about his person, without comment or hinderance.
“It is your own ass,” cried Ellen,
