But Chaucer's poetry derived its power to please from yet another quality; and in this he was the first of our English poets to emulate the poets of the two literatures to which in the matter of his productions, and in the ornaments of his diction, he owed so much. There is in his verse a music which hardly ever wholly loses itself, and which at times is as sweet as that in any English poet after him. This assertion is not one which is likely to be gainsaid at the present day, when there is not a single lover of Chaucer who would sit down contented with Dryden's condescending mixture of censure and praise. "The verse of Chaucer," he wrote, "I confess, is not harmonious to us. They who lived with him, and some time after him, thought it musical; and it continues so, even in our judgment, if compared with the numbers of Lydgate and Gower, his contemporaries: there is a rude sweetness of a Scotch tune in it, which is natural and pleasing, though not perfect." At the same time, it is no doubt necessary, in order to verify the correctness of a less balanced judgment, to take the trouble, which, if it could but be believed, is by no means great, to master the rules and usages of Chaucerian versification. These rules and usages the present is not a fit occasion for seeking to explain. (It may, however, be stated that they only partially connect themselves with Chaucer's use of forms which are now obsolete--more especially of inflexions of verbs and substantives (including several instances of the famous final e), and contractions with the negative ne and other monosyllabic words ending in a vowel, of the initial syllables of words beginning with vowels or with the letter h. These and other variations from later usage in spelling and pronunciation--such as the occurrence of an e (sometimes sounded and sometimes not) at the end of words in which it is now no longer retained, and again the frequent accentuation of many words of French origin in their last syllable, as in French, and of certain words of English origin analogously--are to be looked for as a matter of course in a last writing in the period of our language in which Chaucer lived. He clearly foresaw the difficulties which would be caused to his readers by the variations of usage in spelling and pronunciation--variations to some extent rendered inevitable by the fact that he wrote in an English dialect which was only gradually coming to be accepted as the uniform language of English writers. Towards the close of his "Troilus and Cressid," he thus addresses his "little book," in fear of the mangling it might undergo from scriveners who might blunder in the copying of its words, or from reciters who might maltreat its verse in the distribution of the accents:--
