“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.
