Still what we have is no mean bulk of work for any man to have accomplished, especially when it is considered how extraordinarily good much of it is. To classify it is not particularly easy; and I doubt, myself, whether any classification is necessary. De Quincey himself tried, and made rather a muddle of it. Professor Masson is trying also. But, in truth, except those wonderful purple patches of "numerous" prose, which are stuck all about the work, and perhaps in strictness not excepting them, everything that De Quincey wrote, whether it was dream or reminiscence, literary criticism or historical study, politics or political economy, had one characteristic so strongly impressed on it as to dwarf and obscure the differences of subject. It is not very easy to find a description at once accurate and fair, brief and adequate, of this peculiarity; it is best hinted at in a remark on De Quincey's conversation which I have seen quoted somewhere (whether by Professor Masson or not I hardly know), that it was, with many interesting and delightful qualities, a kind of "rigmarole." So far as I remember, the remark was not applied in any unfriendly spirit, nor is it adduced here in any such. But both in the printed works, in the remembrances of De Quincey's conversation which have been printed, in his letters which are exactly like his articles, and in those astonishing imaginary conversations attributed to him in the _Noctes Ambrosianæ_, which are said, by good authorities, exactly to represent his way of talk, this quality of rigmarole appears. It is absolutely impossible for him to keep to his subject, or any subject. It is as impossible for him to pull himself up briefly in any digression from that subject. In his finest passages, as in his most trivial, he is at the mercy of the will-o'-the-wisp of divagation. In his later re-handlings of his work, he did to some extent limit his followings of this will-o'-the-wisp to notes, but by no means always; and both in his later and in his earlier work, as it was written for the first time, he indulged them freely in the text.
