A, B, C, are, as you know, the first three letters of the alphabet, and the children in the picture are just beginning to learn them. It seems hard to them at first, but it will be easy presently. They will soon learn the name and shape of all the letters, and then will go on to learn what letters make a word, and then what meaning the word has. Thus they will soon be able to read and spell every word, and sit down and read the nice books in papa’s library.
