He had a friend named Richard Steele, with whom we must sometime get acquainted. This Mr. Steele was editor of a paper called _The Tattler_, for which Addison wrote a great deal. The paper which followed _The Tattler_ was named _The Spectator_, and in these two papers are gathered some of the finest writings of the two men. Newspapers were not so plenty then as now, and _The Spectator_ became famous. Everybody took it. Addison's essays which were written for it are still read and admired. When he was about forty-six years old, he quarrelled with his old friend Steele, and they took to writing against each other in the papers, and calling one another names, like naughty children. At least Steele did; I am not sure that Addison ever stooped so low. He did not live long after that. In fact, he died in the June after he was forty-seven. He was buried in Westminster Abbey in the Poets' Corner. Now you have been introduced to him, I hope as you grow older you will be interested to study his character. CHAPTER III. AGASSIZ, LOUIS JOHN RUDOLPH. Isn't that a pretty name? When he was a little Swiss boy roaming about his home, I wonder if his mother called him Louis or Rudolph, or plain John? How many years ago was that? Oh, not so very many. It was one May day, in 1807, that he opened his eyes on this world. I don't know very much about his boyhood that can be told here. He was always a good scholar. Everybody who has anything to say of him seems to be sure of that. And on questioning them, I find they mean by it that he worked hard at his lessons and learned them. No boy or girl must think that good scholars are born so. Every one of them has to work for their wisdom. Our boy studied at home. His father was a minister. When he was old enough he was sent away to the best schools within reach, where he studied medicine. He became a famous man, but not as a physician. The fact is he was an ichthyologist. Ah, now I've caught you! Who knows the meaning of that word? Boys, are there any ichthyologists among your friends? I asked a little girl what the word meant. She did not know and turned to her tall brother who was studying Latin. "Humph!" he said. "Of course I know. It is one who understands ichthyology." "But what is ichthyology?" she persisted. "Why, it is--it is ichthyology, of course," he said; and that is as much as he seemed to know about it. Really, I think we can do better than that. An ichthyologist is one who understands all about fishes. Think of the little slippery, scaly things having such a long word as that belonging to them! Where did they get it? Oh, go back to the Greek language, and ask your father, or your brother, or somebody, to tell you the Greek word for fish, and you will be able to guess the rest out for yourselves.
