Any writer who has read even a little will know what is meant by the word intelligible. It is not sufficient that there be a meaning that may be hammered out of the sentence, but that the language should be so pellucid that the meaning should be rendered without an effort of the reader;--and not only some proposition of meaning, but the very sense, no more and no less, which the writer has intended to put into his words. What Macaulay says should be remembered by all writers: "How little the all-important art of making meaning pellucid is studied now! Hardly any popular author except myself thinks of it." The language used should be as ready and as efficient a conductor of the mind of the writer to the mind of the reader as is the electric spark which passes from one battery to another battery. In all written matter the spark should carry everything; but in matters recondite the recipient will search to see that he misses nothing, and that he takes nothing away too much. The novelist cannot expect that any such search will be made. A young writer, who will acknowledge the truth of what I am saying, will often feel himself tempted by the difficulties of language to tell himself that some one little doubtful passage, some single collocation of words, which is not quite what it ought to be, will not matter. I know well what a stumbling-block such a passage may be. But he should leave none such behind him as he goes on. The habit of writing clearly soon comes to the writer who is a severe critic to himself. As to that harmonious expression which I think is required, I shall find it more difficult to express my meaning. It will be granted, I think, by readers that a style may be rough, and yet both forcible and intelligible; but it will seldom come to pass that a novel written in a rough style will be popular,--and less often that a novelist who habitually uses such a style will become so. The harmony which is required must come from the practice of the ear. There are few ears naturally so dull that they cannot, if time be allowed to them, decide whether a sentence, when read, be or be not harmonious. And the sense of such harmony grows on the ear, when the intelligence has once informed itself as to what is, and what is not harmonious. The boy, for instance, who learns with accuracy the prosody of a Sapphic stanza, and has received through his intelligence a knowledge of its parts, will soon tell by his ear whether a Sapphic stanza be or be not correct. Take a girl, endowed with gifts of music, well instructed in her art, with perfect ear, and read to her such a stanza with two words transposed, as, for instance-- Mercuri, nam te docilis magistro Movit Amphion _canendo lapides_, Tuque testudo resonare septem Callida nervis--
