A single case will sufficiently illustrate the nature of some of these apparitions. In the absence of sleep, and while engaged as was not unusual at this period in the perpetration of doggerel verse, the irritation of the stomach became intolerable. The sensation seemed similar to what. I had read of the final gnawings of hunger in persons dying of starvation; a new vitality appeared to be imparted to the organ, revealing to the consciousness a capacity for suffering previously unsuspected. In the earlier stages, this feeling, which did not exhibit itself till somewhat late in the process of leaving off opium, was marked by an insatiable craving for stimulus of some sort, and a craving which would hardly take denial. While suffering in this way intolerably on one occasion, and after having attempted in vain to find some possible alleviation suggested in the pages of De Quincey, which lay near me, I threw myself back on the bed with the old resolution to fight it out. Almost immediately an animal like a weasel in shape, but with the neck of a crane and covered with brilliant plumage, appeared to spring from my breast to the floor. A venerable Dutch market-woman, of whom I had been in the habit of purchasing celery, seemed to intervene between me and the animal, begging me not to look at it, and covering it with her apron. Just as I was about to remonstrate against her interference, something seemed to give way in the chest and the violence of the pain suddenly abated. It may aid the reader to form some adequate notion of the dreary length to which these nights drew themselves along, to mention that on one occasion, wearied out and disgusted with such illusions, I resolved neither to look at the clock nor open my eyes for the next two hours. It then wanted ten minutes to one; at ten minutes to three my compact with myself would close. For what seemed thousands upon thousands of times I listened to the clock's steady ticking. I heard it repeat with murderous iteration, "Ret-ri-bu-tion," varied occasionally, under some new access of pain, with other utterances. Though ordinarily so little endowed with the poetic gift as never to have attempted to write a line of verse, yet at this time, and for a few days previous, I had experienced a strange development of the rhythmical faculty, and on this particular occasion I made verses, such as they were, with incredible ease and rapidity. I remember being greatly troubled by the necessity for a popular national hymn, and manufactured several with extempore rapidity. Had their merit at all corresponded with the frightful facility with which they were composed, they would have won universal popularity. Unfortunately, the effusions were never written down, and can not, therefore, be added to that immense mass of trash which demonstrates the still possible advent of a true American _Marseillaise_.
