A lean, hungry, half-starved Wolf happened, one moonshiny night, to meet with a jolly, plump, well-fed Mastiff; and after the first compliments were passed, says the Wolf:--"You look extremely well. I protest, I think I never saw a more graceful, comely person; but how comes it about, I beseech you, that you should live so much better than I? I may say, without vanity, that I venture fifty times more than you do; and yet I am almost ready to perish with hunger." The Dog answered very bluntly, "Why, you may live as well, if you will do the same for it that I do."--"Indeed? what is that?" says he.--"Why," says the Dog, "only to guard the house a-nights, and keep it from thieves."--"With all my heart," replies the Wolf, "for at present I have but a sorry time of it; and I think to change my hard lodging in the woods, where I endure rain, frost, and snow, for a warm roof over my head, and a bellyful of good victuals, will be no bad bargain."--"True," says the Dog; "therefore you have nothing more to do but to follow me." Now, as they were jogging on together, the Wolf spied a crease in the Dog's neck, and having a strange curiosity, could not forbear asking him what it meant. "Pooh! nothing," says the Dog.--"Nay, but pray--" says the Wolf.--"Why," says the Dog, "if you must know, I am tied up in the daytime, because I am a little fierce, for fear I should bite people, and am only let loose a-nights. But this is done with design to make me sleep a-days, more than anything else, and that I may watch the better in the night-time; for as soon as ever the twilight appears, out I am turned, and may go where I please. Then my master brings me plates of bones from the table with his own hands, and whatever scraps are left by any of the family, all fall to my share; for you must know I am a favorite with everybody. So you see how you are to live. Come, come along: what is the matter with you?"--"No," replied the Wolf, "I beg your pardon: keep your happiness all to yourself. Liberty is the word with me; and I would not be a king upon the terms you mention."


JEAN LOUIS RODOLPHE AGASSIZ

(1807-1873)

t first, when a mere boy, twelve years of age," writes the great Swiss naturalist, "I did what most beginners do. I picked up whatever I could lay my hands on, and tried, by such books and authorities as I had at my command, to find the names of these objects. My highest ambition at that time, was to be able to designate the plants and animals of my native country correctly by a Latin name, and to extend gradually a similar knowledge in its application to the productions of other countries. This seemed to me, in those days, the legitimate aim and proper work of a naturalist. I still possess manuscript volumes in which I entered the names of all the animals and plants with which I became acquainted, and I well remember that I then ardently hoped to acquire the same superficial familiarity with the whole creation. I did not then know how much more important it is to the naturalist to understand the structure of a few animals than to command the whole field of scientific nomenclature. Since I have become a teacher, and have watched the progress of students, I have seen that they all begin in the same way. But how many have grown old in the pursuit, without ever rising to any higher conception of the study of nature, spending their life in the determination of species, and in extending scientific terminology! Long before I went to the university, and before I began to study natural history under the guidance of men who were masters in the science during the early part of this century, I perceived that though nomenclature and classification, as then understood, formed an important part of the study, being, in fact, its technical language, the study of living beings in their natural element was of infinitely greater value. At that age--namely, about fifteen--I spent most of the time I could spare from classical and mathematical studies in hunting the neighboring woods and meadows for birds, insects, and land and fresh-water shells. My room became a little menagerie, while the stone basin under the fountain in our yard was my reservoir for all the fishes I could catch. Indeed, collecting, fishing, and raising caterpillars, from which I reared fresh, beautiful butterflies, were then my chief pastimes. What I know of the habits of the fresh-water fishes of Central Europe I mostly learned at that time; and I may add, that when afterward I obtained access to a large library and could consult the works of Bloch and Lacépède, the only extensive works on fishes then in existence. I wondered that they contained so little about their habits, natural attitudes, and mode of action, with which I was so familiar."

It is this way of looking at things that gives to Agassiz's writings their literary and popular interest. He was born in Mortier, Canton Fribourg, May 28th, 1807, the son of a clergyman, who sent his gifted son to the Universities of Zürich, Heidelberg, and Munich, where he acquired reputation for his brilliant powers, and entered into the enthusiastic, intellectual, and merry student-life, taking his place in the formal duels, and becoming known as a champion fencer. Agassiz was an influence in every centre that he touched; and in Munich, his room and his laboratory, thick with clouds of smoke from the long-stemmed German pipes, was a gathering-place for the young scientific aspirants, who affectionately called it "The Little Academy." At the age of twenty-two, he had published his 'Fishes of Brazil,' a folio that brought him into immediate recognition. Cuvier, the greatest ichthyologist of his time, to whom the first volume was dedicated, received him as a pupil, and gave to him all the material that he had been collecting during fifteen years for a contemplated work on Fossil Fishes. In Paris Agassiz also won the friendship of Humboldt, who, learning that he stood in need of money, presented him with so generous a sum as to enable the ambitious young naturalist to work with a free and buoyant spirit.

His practical career began in 1832, when he was installed at Neufchâtel, from which point he easily studied the Alps. Two years later, after the 'Poissons fossiles' (Fossil Fishes) appeared, he visited England to lecture. Then returning to his picturesque home, he applied himself to original investigation, and through his lectures and publications won honors and degrees. His daring opinions, however, sometimes provoked ardent discussion and angry comment.
