Throughout this book, and the next, you will find passages taken from the writings of the best English authors. But the passages are not all equal, nor are they all such as we would call "the best," and the more you read and are able to judge them for yourselves, the better you will be able to see what is the difference between the best and those that are not so good. By the best authors are meant those who have written most skilfully in prose and verse. Some of these have written in prose, because they wished to tell us something more fully and freely than they could do if they tied themselves to lines of an equal number of syllables, or ending with the same sound, as men do when they write poetry. Others have written in verse, because they wished rather to make us think over and over again about the same thing, and, by doing so, to teach us, gradually, how much we could learn from one thing; if we think sufficiently long and carefully about it; and, besides this, they knew that rhythmical or musical language would keep longest in our memory anything which they wished to remain there; and by being stored up in our mind, would enrich us in all our lives after. In these books you will find pieces taken from authors both in prose and verse. But of the authors who have made themselves famous by the books which they have written in our language, many had to be set aside. Because many writers, though their books are famous, have written so long ago, that the language which they use, though it is really the same language as our own, is yet so old-fashioned that it is not readily understood. By and by, when you are older, you may read these books, and find it interesting to notice how the language is gradually changing; so that, though we can easily understand what our grandfathers or our great grandfathers wrote, yet we cannot understand, without carefully studying it, what was written by our own ancestors a thousand, or even five hundred, years ago.
