Among the stories that Clemens did show, or read, to Howells that summer was “The Belated Passport,” a strong, intensely interesting story with what Howells in a letter calls a “goat’s tail ending,” perhaps meaning that it stopped with a brief and sudden shake—­with a joke, in fact, altogether unimportant, and on the whole disappointing to the reader.  A far more notable literary work of that summer grew out of a true incident which Howells related to Clemens as they sat chatting together on the veranda overlooking the river one summer afternoon.  It was a pathetic episode in the life of some former occupants of The Pines—­the tale of a double illness in the household, where a righteous deception was carried on during several weeks for the benefit of a life that was about to slip away.  Out of this grew the story, “Was it Heaven? or Hell?” a heartbreaking history which probes the very depths of the human soul.  Next to “Hadleyburg,” it is Mark Twain’s greatest fictional sermon.

Clemens that summer wrote, or rather finished, his most pretentious poem.  One day at Riverdale, when Mrs. Clemens had been with him on the lawn, they had remembered together the time when their family of little folks had filled their lives so full, conjuring up dream-like glimpses of them in the years of play and short frocks and hair-plaits down their backs.  It was pathetic, heart-wringing fancying; and later in the day Clemens conceived and began the poem which now he brought to conclusion.  It was built on the idea of a mother who imagines her dead child still living, and describes to any listener the pictures of her fancy.  It is an impressive piece of work; but the author, for some reason, did not offer it for publication.—­[This poem was completed on the anniversary of Susy’s death and is of considerable length.  Some selections from it will be found under Appendix U, at the end of this work.]

Mrs. Clemens, whose health earlier in the year had been delicate, became very seriously ill at York Harbor.  Howells writes: 

At first she had been about the house, and there was one gentle afternoon when she made tea for us in the parlor, but that was the last time I spoke with her.  After that it was really a question of how soonest and easiest she could be got back to Riverdale.

She had seemed to be in fairly good health and spirits for several weeks after the arrival at York.  Then, early in August, there came a great celebration of some municipal anniversary, and for two or three days there were processions, mass-meetings, and so on by day, with fireworks at night.  Mrs. Clemens, always young in spirit, was greatly interested.  She went about more than her strength warranted, seeing and hearing and enjoying all that was going on.  She was finally persuaded to forego the remaining ceremonies and rest quietly on the pleasant veranda at home; but she had overtaxed herself and a collapse was inevitable.  Howells and two friends called one afternoon, and a friend of the Queen of Rumania, a Madame Hartwig, who had brought from that gracious sovereign a letter which closed in this simple and modest fashion:
