I remember, too, how one day, when in Professor Dodd's class of mathematics, I, instead of attending to the lecture, read surreptitiously Cardanus _de Subtilitate_ in an old vellum binding, and carelessly laid it on the table afterwards, where Professor Dodd found it, and directed at me one of his half-laughing Mephistophelian glances. Reading of novels in lectures was not unknown; but for Dodd to find anything so caviare-like as Cardanus among our books was unusual. George Boker remarked once, that while Professor Dodd was a Greek, Professor James Alexander was an old Roman, which was indeed a good summary of the two. I have and always had a bad memory, but I continued to retain what I read by repetition or reviewing and by _collocation_, which is a marvellous aid in retaining images. For, in the first place, I read entirely by GROUPS; and if I, for instance, attacked Blair's "Rhetoric," Longinus and Burke Promptly followed; and if I perused "Rambles in the Footsteps of Don Quixote," I at once, on principle, followed it up with "Spain in 1830," and a careful study of Ford's Guide-Book for Spain, and perhaps a score of similar books, till I had got Spain well into me. And as I have found by years of observation and much research, having written a book on Education partly based on this principle, ten books on any subject read together, profit more than a hundred at intervals. And I may here add, that if this record of what I read be dull, it is still that of my real youthful life, giving the clue to my mind as it was formed. Books in those days were the only events of my life. Long before I went to college I had an attack of Irish antiquities, which I relieved by reading O'Brien, Vallancey, the more sensible Petrie, and O'Somebody's Irish grammar, aided by old Annie Mooney, who always remained by us. In after years I discovered an Ogham inscription and the famed Ogham tongue, or _Shelta_, "the lost language of the bards," according to Kuno Meyer and John Sampson. During my first half-year a college magazine was published, and I, a Freshman, was requested to contribute to the first number. I sent in an article on the history of English poetry. Before I wrote it, the great man among the senior students asked leave to be allowed to write it with me. I did not quite like the idea, but reflecting that the association would give me a certain prestige, I accepted his aid. So it appeared; but it was regarded as mine. Professor Dodd said something to me about the inexpediency of so young a person appearing in print. I could have told him that I had already published several poems, &c., in Philadelphian newspapers, but reflecting that it was not kind to have the better of him, I said nothing. From that time I published something in every number. My second article was an essay on Spinoza, and I still think it was rather good for a boy of sixteen.
