As regards the episodes, it may just be said in a word that they are appropriate, and instead of retarding the movement of the piece, as has sometimes been alleged, they serve to give it breadth and massiveness of effect. Of course, there will always be found those who think them too long, just as there are those whose narrowness of view constrains them to wish the Introductions away. If the poet's conception of Marmion be fully considered, it will be seen that the Host's Tale is an integral part of his purpose; and there is surely no need to defend either Sir David Lyndsay's Tale or the weird display at the cross of Edinburgh. The episode of Lady Heron's singing carries its own defence in itself, seeing that the song of 'Lochinvar' holds a place of distinction among lyrics expressive of poetical motion. After all, we must bear in mind that though it pleases Scott to speak of his tale as flowing on 'wild as cloud, as stream, as gale,' he was still conscious that he was engaged upon a poem, and that a poem is regulated by certain artistic laws. If we strive to grasp his meaning we shall not be specially inclined to carp at his method. It may at the same time be not unprofitable to look for a moment at some of the notable criticisms of the poem. IV. CRITICISMS OF THE POEM. When 'Marmion' was little more than begun Scott's publishers offered him a thousand pounds for the copyright, and as this soon became known it naturally gave rise to varied comment. Lord Byron thought it sufficient to warrant a gratuitous attack on the author in his 'English Bards and Scotch Reviewers.' This is a portion of the passage:-- 'And think'st thou, Scott! by vain conceit perchance, On public taste to foist thy stale romance. Though Murray with his Miller may combine To yield thy muse just half-a-crown per line? No! when the sons of song descend to trade, Their bays are sear, their former laurels fade.' As a matter of fact, there was on Scott's part no trade whatever in the case. If a publisher chose to secure in advance what he anticipated would be a profitable commodity, that was mainly the publisher's affair, and the poet would have been a simpleton not to close with the offer if he liked it. Scott admirably disposes of Byron as follows in the 1830 Introduction:--
